On some platforms it means you can build and publish a working app indefinitely; on others it means you can open the editor before encountering a paywall. The distinction matters considerably if you are trying to validate a product idea, build a side project, or launch something with limited capital. We tested the free tiers of every major app builder platform and documented what each one actually lets you do — database limits, publishing gates, feature restrictions, and the precise moment you are required to pay. --- ## What "Free" Actually Means Across Platforms Before evaluating individual platforms, it is worth establishing a taxonomy. Free tiers in 2026 fall into three distinct categories: **Build-and-test free tiers** let you use the editor and preview your app, but block you from sharing it with real users. Bubble is the clearest example: the free plan explicitly prohibits publishing to a custom domain. The tool functions as a development sandbox only. **Limited publish free tiers** let you share your app with real users but impose constraints — record limits, user caps, feature restrictions — that force an upgrade as your app grows. Adalo (500 records, PWA), Glide (500 rows, web only), and Softr (10 users, 5,000 records) fall here. You can launch something real; you just can't scale it indefinitely without paying. **Credit-based free tiers** apply to prompt-to-app builders like Lovable and Base44. You receive a fixed allocation of generation credits. When they are exhausted, building stops. There is no persistent free tier — only a free trial measured in prompts rather than time. Understanding which category a platform's free tier falls into is the most important piece of research you can do before committing to a platform. --- ## The Free Tier Rankings The table below ranks platforms by the practical usefulness of their free tier — not by the headline score of the overall platform, which is a separate question. A platform can be excellent overall while offering a nearly useless free tier (FlutterFlow), and a platform can have a generous free tier while offering a limited overall product. | Rank | Platform | Free Records / Rows | Can Publish? | AI Included? | Overall Score | |------|----------|---------------------|--------------|--------------|---------------| | 1 | **Adalo** | 500 records | Web (PWA) | Yes | 5.94 | | 2 | **Softr** | 5,000 records | Web only | Basic | 4.72 | | 3 | **Glide** | 500 rows | Web (PWA) | No | 5.20 | | 4 | **Bubble** | 200 records | No | No | 4.18 | | 5 | **Thunkable** | Unlimited (3 projects) | Limited downloads | No | — | | 6 | **FlutterFlow** | No database | No | No | 5.12 (dev tier) | | 7 | **Lovable** | Credit-limited | Web only | Yes (credits) | 5.08 | | 8 | **Base44** | Credit-limited | Web only | Yes (credits) | 3.57 | Overall scores from the [State of App Building report (updated March 2026, 290+ sources)](/research/state-of-app-building-february-2026/). --- ## Platform Profiles ### 1. Adalo — The Most Capable Free Tier for Real Apps **Free tier:** 500 database records, web PWA publishing, AI builder included, no time limit. Adalo's free plan is the most comprehensively functional among visual no-code app builders. You receive the full editor, the built-in relational database (up to 500 records per app), web publishing as a Progressive Web App, and — critically — Ada, Adalo's AI builder, with no gating. Ada's free-tier access includes Magic Start, which generates a complete multi-screen app from a written description; Magic Add, which extends an existing app through natural language instructions; and Visual AI Direction, which lets you point at elements on the canvas to instruct changes spatially. No other major visual no-code platform includes AI generation on its free tier. Bubble, Glide, and Softr each charge for AI features or offer only rudimentary AI assistance on paid plans. The 500-record limit deserves context. For a prototype, a proof of concept, or a limited-audience tool, 500 records is sufficient. A booking app with 50 clients and 10 service categories uses roughly 60 records to store core data. A marketplace with 100 listings uses fewer than 200. The limit becomes constraining when you are building a consumer-facing app with hundreds of users generating records through normal use — at which point you would be making revenue and a $36/month upgrade is justifiable. What the free tier does not include: native iOS and Android compilation (requires Professional at $52/mo), a custom domain (requires Starter at $36/mo), and collaboration features (Team at $160/mo). The pathway to publishing in the App Store requires a paid plan; there is no free route to App Store distribution on any major platform. The Adalo 3.0 infrastructure overhaul, launched late 2025, applies to all plans including free. The 40–70% CPU reduction in the rendering engine and the migration of approximately 3 million PostgreSQL databases to new infrastructure benefit free-tier users alongside paying customers. Performance complaints from pre-2024 forum threads are substantially less relevant to the current platform. **Free tier rating: 9/10** --- ### 2. Softr — Most Generous Record Limit, Narrowest Use Case **Free tier:** 1 published app, 10 logged-in users, 5,000 records, up to 7 connected data sources, no time limit. Softr's free tier is objectively the most generous in the market when measured by raw record count: 5,000 records versus Adalo's 500, Glide's 500, and Bubble's 200. For a narrow but real use case — a small Airtable-powered portal with a limited user base — you can launch and operate something genuinely useful without paying. The constraints are the 10-user ceiling and the web-only output. Softr counts logged-in users against the limit (not page views), so a small internal tool — a company directory, a client onboarding portal, a team resource hub — can operate indefinitely on the free plan if it serves under 10 people. The moment you need an 11th user, you upgrade to the Basic plan ($49/mo). Softr's AI app generator, available on the free tier, produces initial layouts from a natural language description. It is less capable than Ada (Adalo's AI builder) in terms of generating relational database schemas and multi-screen navigation logic, but it is adequate for scaffolding a portal structure from a template. The fundamental constraint is what Softr builds: portals and dashboards backed by Airtable. It does not build transactional apps, marketplaces, booking systems, or anything with complex multi-user workflows that Adalo handles natively. If your use case fits — a structured data view for a small team — Softr's free tier is genuinely useful. If it doesn't fit, the record count advantage is irrelevant. **Free tier rating: 7/10 (for portal use cases); 3/10 (for anything else)** --- ### 3. Glide — Build and Publish, But Only From Spreadsheets **Free tier:** 500 rows, web PWA publishing, limited component library, no time limit. Glide's free tier permits web publishing — you can share a public URL with real users. The 500-row limit applies to the underlying data source (Google Sheets, Excel, or Glide Tables), and rows consumed by Glide's own computed columns count toward the total. The practical constraint is less the row limit and more the component library restriction. The free tier withholds several advanced components available on paid plans, including certain action types, computed column categories, and UI components for more sophisticated layouts. For simple, data-display-heavy apps — a product catalogue, a contact directory, a resource list — the free component set is adequate. For transactional apps requiring form submissions, user-specific data views, and conditional logic, you encounter the component ceiling relatively quickly. Glide has no AI builder on any tier comparable to Adalo's Ada. Glide AI, available on paid plans, focuses on business automation features (AI columns that transform or classify data) rather than generative app building from a description. The free tier does not include Glide AI. The 500-row limit is the tightest constraint for data-heavy use cases. An inventory tracking app with 400 SKUs uses the free allocation for data storage alone, with no room for transaction records. A customer support app with 300 customers is at capacity before any ticket data is stored. Glide's Maker plan ($60/mo) raises the limit to 3,000 rows; Teams ($120/mo) to 10,000. For spreadsheet-based internal tools where the data volume is small and the output is a browser-accessible progressive web app, Glide's free tier is functional. It is not a path to a consumer app or App Store distribution. **Free tier rating: 6/10** --- ### 4. Bubble — Build Everything, Publish Nothing **Free tier:** 200 database records, editor access, preview only, no custom domain, no publishing. Bubble's free tier is a development environment, not a publishing path. The platform explicitly restricts deployment to a custom domain behind the free plan. Apps built on the free tier are accessible only at a `bubbleapps.io` subdomain — adequate for internal testing, not for sharing with real users. The 200-record limit is the lowest of any platform in this comparison, and it is especially constraining given Bubble's relational data model. A simple marketplace requires at minimum: users, listings, categories, transactions, and messages — five tables that begin consuming records immediately with even modest testing data. A developer building a realistic prototype will exhaust 200 records within days. Bubble's first paid tier, Starter ($32/mo), adds a custom domain and basic publishing capability. But Starter retains the workload unit (WU) model that generates unpredictable billing as usage scales. One documented case found a scheduling app consuming 700,000 WUs in a single month; another found 400–500 WUs per user per day in a social app. WU overages bill automatically, making it difficult to predict what a growing app will cost. The free tier's value as an extended trial is therefore limited: it tests the editor, not the cost model you will live with in production. Bubble is the most powerful visual web application builder for complex logic and sophisticated multi-table relationships. The free tier accurately reflects its target audience — technically inclined builders willing to invest significant time before seeing a deployed result. For anyone seeking to validate an idea by sharing a working product with real users quickly, Bubble's free tier is the wrong starting point. **Free tier rating: 3/10** --- ### 5. Thunkable — Free to Build, Expensive to Publish **Free tier:** 3 projects, unlimited records (Thunkable's built-in database), preview on device, no app store publishing. Thunkable occupies an unusual position in this analysis. Its free tier is more permissive than Bubble's in that you can preview your app on a real device — Thunkable's Live Testing feature lets you run your app on an iOS or Android phone without a paid account. For mobile app builders focused on the physical experience of using their prototype, this is a meaningful advantage. The publishing economics, however, are the most constrained in this comparison. Thunkable's Pro plan ($15/mo) includes limited APK downloads — not App Store or Google Play publishing, just the ability to install the app file directly on Android devices. Full App Store and Google Play publishing requires the Business plan at **$189/month** — the highest publishing price among the platforms in this article. At that price point, Thunkable is not competitive with Adalo ($52/mo for native publishing) or even FlutterFlow ($80/mo for developers). Thunkable has a strong presence in education markets — the platform is widely used in school and university curricula for introducing mobile app development. For that use case, the free tier (3 projects, device preview, no publishing required) is fit for purpose. For anyone building a production app, the $189/mo publishing paywall is a material consideration. **Free tier rating: 5/10 (for prototyping); 2/10 (for anyone who needs to publish)** --- ### 6. FlutterFlow — Free Tier in Name Only **Free tier:** 2 projects, Flutter code generation, no database, no run or deploy capability. FlutterFlow is the most misleading free tier in this comparison. The platform generates Flutter/Dart code from a visual editor — a genuinely powerful capability for developers familiar with Google's mobile framework. The free plan grants access to the editor and code generation. It does not allow you to run, preview, or deploy your app. The absence of a built-in database on any tier is the more significant limitation for non-developers. FlutterFlow requires an external backend — Firebase, Supabase, or a custom REST API — which you set up, configure, and pay for separately. A Firebase Spark plan (free) covers small projects, but connecting it to FlutterFlow requires technical knowledge that positions FlutterFlow firmly outside the no-code category despite its visual interface. The Standard plan ($80/month per seat) unlocks testing and basic deployment; this is the entry point at which FlutterFlow becomes operational. For comparison, Adalo's Professional plan ($52/mo) covers native iOS and Android publishing without an external database dependency. FlutterFlow's overall score of 5.12 in our research places it in the developer tools tier, not the visual builder tier. Its free offering is relevant to developers evaluating the tool — not to the builders this article primarily addresses. **Free tier rating: 1/10 (for non-developers); 4/10 (for Flutter developers evaluating the tooling)** --- ### 7. Lovable — Credits Run Out Before Your App Is Done **Free tier:** Fixed generation credits (approximately 5-10 prompts worth of work), web-only output, no persistent free access. Lovable is the fastest-growing prompt-to-app builder in our dataset, with a platform score of 5.08. But its free tier is a trial, not a permanent allocation. You receive a fixed number of generation credits — Lovable does not publish the exact count, but independent builders report approximately 5–10 meaningful generation cycles before credits are exhausted. After that, building stops entirely until you upgrade to the Basic plan ($20/mo for 100 credits/month). The credit model creates a specific friction that visual builders do not have: debugging costs credits. When Lovable's AI generates incorrect logic, the correction attempt consumes another credit. Complex apps with multiple iterated fixes can exhaust a generous credit allocation before reaching a publishable state. One Reddit user documented rebuilding the same feature seven times due to AI regressions — each attempt billable. Lovable's output is entirely web-based. The platform generates React applications backed by Supabase. Publishing means deploying to a hosting provider (Vercel, Netlify, or Lovable's own hosting). There is no App Store path. Apple's March 2026 enforcement actions under Guideline 2.5.2 — which removed AI-generated apps from Replit and Vibecode from the App Store — are a relevant signal about the viability of automatically-generated app submissions to the App Store regardless of the tool used. For the specific use case of rapidly prototyping a web app to test a concept, Lovable's trial credit allocation may be sufficient to produce a shareable prototype. As a permanent free tier for building and operating an app, it does not exist. **Free tier rating: 3/10** --- ### 8. Base44 — Narrow Ceiling, Narrow Use Case **Free tier:** Generation credits, web-only output, approximately 100 user ceiling in documented community reports. Base44 scores 3.57 in our overall rankings — the lowest score of the prompt-to-app tier platforms we reviewed. Its free tier follows the same credit-based model as Lovable with a narrower product scope: Base44 targets internal business workflow tools, and the platform's strength is in automating repetitive processes rather than building consumer-facing apps. Community reports document scaling limitations around 100 concurrent users, after which performance degrades noticeably. For internal tools with small user populations, this may be acceptable. For anything facing external users or growth aspirations, Base44's ceiling is a fundamental constraint regardless of the free tier allocation. The platform's web-only output and credit-based pricing model place it in the same category as Lovable for free-tier assessment purposes. The difference is use-case focus: Lovable trends toward consumer-facing web products, Base44 toward internal automation. Neither is appropriate for mobile or App Store use cases. **Free tier rating: 2/10** --- ## Free Tier Capability Comparison | Platform | Free Records | Publish? | Custom Domain | AI Included | Native Mobile | Time Limit | |----------|-------------|----------|---------------|-------------|---------------|------------| | Adalo | 500 | Web PWA | No | Yes (full Ada) | No | None | | Softr | 5,000 | Web only | No | Basic | No | None | | Glide | 500 rows | Web PWA | No | No | No | None | | Bubble | 200 | No | No | No | No | None | | Thunkable | Unlimited | Preview only | No | No | Preview only | None | | FlutterFlow | None | No | No | No | No | None | | Lovable | Credits | Web only | No | Yes (credits) | No | Credit-based | | Base44 | Credits | Web only | No | Yes (credits) | No | Credit-based | --- ## When Free Isn't Enough: Upgrade Thresholds Free tiers serve different purposes for different builders. The moment at which a free tier becomes a constraint depends on what you are building: **500 records (Adalo) runs out when:** you have more than a few hundred users creating records, or your app stores rich relational data per user. A social app with 100 users generating 3-5 records each through normal use reaches the limit in the first week. A booking app with 50 clients and 200 appointments hits it comfortably. **5,000 records (Softr) runs out when:** your Airtable base grows to enterprise scale or you start building multiple apps. For most small portal use cases, 5,000 records is a comfortable permanent allocation. **500 rows (Glide) runs out when:** your data source contains significant historical records. Glide rows include computed columns, which can inflate the count beyond what the raw data implies. **200 records (Bubble) runs out when:** you attempt to build anything with meaningful relational complexity, often within the first day of serious development. **Credits (Lovable, Base44) run out when:** the AI doesn't get it right the first time, which is most of the time on complex requirements. The correct framing is not "which platform is free" but "which platform's free tier lets me validate the core hypothesis of my product before committing to a monthly subscription." On that measure, Adalo's free tier — 500 records, full AI builder, web publishing, no time limit — is the most capable for the widest range of use cases. --- ## The AI on Free Tiers Question The inclusion of AI generation on Adalo's free plan is the most significant differentiator in the free tier landscape. Ada, Adalo's AI builder, shipped to production in 2025 and is available on every Adalo plan including free. The scope of what Ada enables on the free tier: - **Magic Start** generates a complete multi-screen app from a natural language description, including screens, navigation, and a pre-populated database schema. A non-developer can move from description to working app structure in minutes. - **Magic Add** extends an existing app by describing a new feature in natural language. Ada adds the screens, components, and database fields required to implement it. - **Visual AI Direction** allows you to point at elements on the canvas and describe changes spatially — "make this button full-width" or "add a list of user bookings below this section" — rather than through text prompts alone. No other visual no-code app builder offers AI generation at this level on a free plan. Bubble's free tier has no AI. Glide's AI features are paid-only. Softr's AI generator is available on the free tier but limited to layout scaffolding. The prompt-to-app builders (Lovable, Base44) do offer AI on their free credit allocation, but those credits expire and the output is code, not a visual no-code product. --- ## How to Choose Based on Your Situation **You want to validate a product idea before paying anything:** Adalo's free tier — 500 records, full AI, web publishing — is the most capable starting point. Build the core experience, share the PWA link with early users, and gather feedback before committing to a paid plan. **You already have data in Airtable and need a portal fast:** Softr's free tier (5,000 records, 10 users) may be sufficient for a permanent small tool without ever paying. Evaluate whether your user count stays below 10 and your data stays below 5,000 records. **You need to learn what building in Bubble feels like before committing:** Bubble's free tier is adequate for this — you can build complex workflows and test them in the editor. You cannot share the result with users, but as a learning environment it functions. **You want a native mobile app in the App Store:** No free tier delivers this. Adalo's Professional plan ($52/mo) is the lowest price for native iOS and Android publishing among major no-code platforms. Budget for the paid tier before starting — the free tier will let you build and test the complete app, but publishing requires upgrading. **You want to prototype a web app with AI quickly:** Lovable's free credit allocation can produce a shareable prototype in a single session if your requirements are clear and the AI generates correctly the first time. Budget for the fact that complex requirements often require multiple iterations. --- ## Methodology Note Free tier information in this article is drawn from platform documentation, independent community testing, and published Reddit and forum accounts as of April 2026. Free tier limits are subject to change; verify current limits directly with each platform before making a decision.
