Best Free App Builders in 2026
Short answer: Draftbit is the best free app builder in 2026: free plan, no card required, 5,000 build credits, live at draftbit.dev, Standard from $12/mo once you outgrow it. Bolt is the pick for a free hosted app from a chat prompt, with 1M tokens a month before you pay. AppSheet is the pick for a free, permanent internal tool capped at 10 test users, never a public launch. Softr allows unlimited apps free but withholds a custom domain until you pay. Adalo and Bubble build for free but block publishing entirely until you pay.
Nine app builders ranked by what the free plan actually unlocks, not by the marketing page, with prices checked on vendor pages in September 2026.
Most "free" app builders let you design a screen for nothing, then charge the moment you want anyone else to see it. Draftbit is the exception on this list: its free plan ships a working app to a live web address, not just a canvas.
This guide only ranks builders with a genuine free tier, no trial clock attached, and scores each one by what the free plan lets you actually do: how many apps, whether you can publish, and what breaks the moment real users show up. The best AI app builders guide and the best AI app builders for non-developers guide rank the same category on overall fit and AI quality; this page answers a narrower question, what a reader with $0 to spend can actually ship.
Toolradar data: of the 154 app builders we track, 91 offer a freemium plan and 32% are paid only, so 68% of this category gives a builder something to try before paying a cent.
Methodology: these 9 picks were ranked against the 154 tools in the app builders category for what their free plan actually includes, checked on each vendor's own US pricing page in September 2026. None of these placements is paid.

Anyone who wants a working, shareable app link today without paying anything.
Draftbit's pricing is fair, especially with a generous free tier for learning and experimentation.
Builders who want a live, hosted result today and can live with Bolt's branding until they upgrade.
Bolt's pricing is fair, offering a clear progression from a free tier to paid options.
Watch out
Potential overage fees for tokens
Teams building an internal tool for a small group who never need a public launch.
AppSheet's pricing is generally fair, especially for small teams starting with the $5/user Starter plan.
Teams already keeping data in Airtable or Sheets who want to test more than one app idea for free.
For teams building internal tools or client portals, the user-count limits are the primary constraint.
Watch out
Softr Workflow actions are capped: 500 on Free, 2,500 on Basic, 10,000 on Professional, 25,000 on Business. Automation-heavy apps burn through these quickly, each form submission, email trigger, or data update counts as an action
Non-technical builders who want a chat-only path to a real app and may hand it to an engineer later.
Lovable is powerful for rapid React prototyping.
Builders already in the Vercel and GitHub ecosystem who want fast UI iteration before paying.
v0 is the leading AI code generation tool for frontend development, purpose-built for React and Tailwind CSS.
Watch out
Credits are consumed based on input and output tokens, not per generation. Longer conversations, larger codebases, and complex prompts consume credits exponentially faster, a multi-turn conversation can cost 5-10x more than a single prompt.
Builders who want an eventual App Store listing and may hand the project to a developer.
FlutterFlow is the leading visual Flutter builder but pricing gets steep for teams.
Watch out
Firebase/Supabase backend costs are separate, Blaze plan required for production Firebase apps
Beginners learning the block-based editor before committing to a paid, private mobile build.
Thunkable's pricing is fair, offering a generous free tier for beginners.
Builders fine with unpublished testing for now who plan to pay before launch anyway.
Adalo is straightforward no-code app pricing with no usage-based surprises on paid tiers.
What a free app builder actually gives you
A free app builder is a platform where you can design, and in the best cases publish, a working application without entering a card. The category splits sharply on that second word: publish.
Draftbit and Bolt let the free plan ship to a real, live address, Draftbit's own draftbit.dev subdomain and Bolt's built-in hosting. AppSheet lets a free app run forever for up to 10 named test users, but never in front of the public. Softr, Lovable, v0, and FlutterFlow let you build and in most cases publish something on free, but cap it with a metered credit, a thin AI allowance, or a missing custom domain. Thunkable and Adalo are the strictest: Thunkable's free apps stay public-only with no live install, and Adalo's free plan cannot publish anywhere at all, not to an app store, not to the web, not to a custom domain.
A reader who only needs to prototype before pitching a client or a boss is well served by any of these nine. A reader who needs a real app live this week for $0 should start at the top of this list, not the bottom.
Why the free tier, not the paid tier, decides the ranking
Every app builder markets its AI, its templates, and its paid plan's ceiling. Almost none leads with what happens if you never pay. That gap matters because most readers hitting this page have not decided the project is worth a subscription yet; they want to test the idea first.
The honest split is publish versus build-only. Bubble's free plan caps out at 50,000 workload units a month and gives a full development editor, but has no live website capability and no custom domain at any usage level: you are testing a product you cannot show anyone outside your own account. Glide's free plan allows 10 projects and 2 team members but zero published apps. Compare that to Draftbit, where the free plan's 5,000 credits go toward an app that is live at a real URL the moment you hit publish, or Bolt, where a free project deploys with real hosting attached, just with Bolt's own branding on it.
The second gap is the metered unit. Lovable's free plan grants 5 build credits a day, capped at 30 a month; v0's free plan resets 7 messages a day with a small monthly credit allowance. Those numbers sound generous until a single real feature burns through a day's allowance in one prompt, which is a different experience than AppSheet's free tier, which never expires but also never leaves prototype mode.
Key Features to Look For
Publishing included on the free plan (Essential)
A usable number of apps or projects (Essential)
Softr's free plan allows an unlimited number of apps, capped instead by 5 app users and 5,000 database records total. Glide caps free projects at 10, and FlutterFlow caps free projects at 2, so the app count matters as much as the credit meter.
A metered unit you can actually predict (Important)
Lovable's free plan grants 5 build credits a day up to 30 a month, Bolt gives 300K tokens a day and 1M a month, and v0 resets 7 messages a day with a monthly credit allowance. A thin daily reset burns out faster than a larger monthly pool on a busy build day.
A custom domain or a subdomain you keep (Important)
Draftbit's free plan ships to its own draftbit.dev subdomain at no cost, and FlutterFlow's free web publishing includes 2 subdomains. Softr withholds a custom domain until you upgrade to Basic, and Adalo withholds any live address, custom or not, until you upgrade to Starter.
No expiration date on the free plan (Important)
AppSheet's free tier for personal or prototype apps never expires and never asks for a card, unlike a builder that runs a time-limited trial disguised as free. Every pick on this list carries a genuine, ongoing free tier, not a countdown.
AI generation available without paying (Nice to have)
FlutterFlow's free plan includes only 5 AI generation requests for the life of the account, a thin trial next to Thunkable's 2,000 AI tokens or Bolt's daily token allowance. A reader planning to lean on AI generation should weigh this before the app count.
What to check before you build on the free tier
Decide if the project needs to be public before you start. AppSheet's free plan is the strongest pick for an internal tool capped at 10 named users, but it will never carry a public launch without a paid seat.
Read the metered unit as a daily rate, not a monthly total. Lovable's 5-credit daily cap and v0's 7-message daily cap reset faster than the monthly figure suggests on a busy build day.
Count how many separate apps the free plan allows: Softr's free plan is unlimited apps, Glide caps at 10 projects, and FlutterFlow caps at 2, a real constraint for anyone testing more than one idea.
If the eventual build is closer to an internal database and workflow tool than a customer-facing product, the wider no-code platforms guide covers backend-heavy options this list leaves out on purpose.
Evaluation Checklist
Confirm on the vendor's own pricing page whether the free plan can publish at all, and to whom, before you build a real project on it.
Build your actual first screen, not the demo prompt, and time how fast the daily or monthly credit meter moves.
Count how many separate ideas you want to test and compare that to the free app or project cap: Softr is unlimited, Glide caps at 10, FlutterFlow caps at 2.
Ask whether the free plan's output can leave the platform later as real code, a factor that matters more once a free prototype turns into something worth keeping.

Mistakes to Avoid
- ×
Building a real launch on Adalo or Bubble's free plan, then discovering neither can publish anywhere until you pay for Starter.
- ×
- ×
Picking AppSheet for a customer-facing product, then hitting the 10 test user ceiling that free plan was never meant to cross.
- ×
- ×
Ignoring Bolt's visible branding on a free-plan site and only noticing it once a client or user sees the live link.
Expert Tips
- →
- →
If the build lives entirely inside your own team, price AppSheet's free tier against a mid-tier paid plan elsewhere before assuming you need to pay.
- →
Read the metered unit as a daily number first, not the monthly total the pricing page leads with.
- →
If the app might outgrow the platform, favor Bolt, FlutterFlow, or Draftbit for a real code export path, even if today's free build looks the same either way.
- →
Test the free plan's actual publish step before you invest real time; a platform that cannot publish free is a design sandbox, not a launch path.
Red Flags to Watch For
- !
A free plan that builds and previews but cannot publish on any channel, like Adalo, when the whole point is a live app for $0.
- !
A credit or token meter with no visible per-action cost, so you cannot tell how fast a real building session will spend it.
- !
A free tier framed as permanent that is actually a disguised trial with a hidden expiration once you dig into the terms.
- !
A public-only free project, like Thunkable's, when the build contains anything you would not want visible to strangers.
- !
A free plan advertised as unlimited apps that turns out capped hard on users, records, or AI credits the moment you scale past a demo.
The Bottom Line
Draftbit is the best free app builder in 2026 for one reason most competitors avoid stating plainly: its free plan actually publishes to a live web address, no card and no upgrade required.
Bolt is the runner-up for anyone who wants free hosting attached to a chat-built app, branding included until you pay. AppSheet is the pick for a permanent internal tool capped at 10 named users. Softr, Lovable, v0, and FlutterFlow all let you build for free but meter the result with app caps, daily credits, or a thin AI allowance. Thunkable and Adalo sit at the bottom because their free plans will not put a real, private app live at all.

Frequently Asked Questions
What is the best free app builder in 2026?
Draftbit is the best free app builder in 2026 for most readers: its free plan includes 5,000 build credits, a Supabase backend, and 1-click publishing to a live draftbit.dev address, all without entering a card. Bolt is the close second for a free hosted app or site built from a chat prompt, with 1M tokens a month before you pay anything.
Which free app builders actually let you publish, not just build?
Draftbit and Bolt both publish a real, live app on the free plan, Draftbit to draftbit.dev and Bolt with its own hosting. AppSheet publishes too, but only to a private group of up to 10 test users. Softr and FlutterFlow allow free publishing with real limits, FlutterFlow to 2 web subdomains and Softr without a custom domain. Adalo, Bubble, Glide, and Thunkable's free plans build but do not publish a live private app at all.
Is there a truly free app builder with no trial or expiration?
Yes. Every builder ranked on this page has a permanent free plan verified on the vendor's own pricing page in September 2026, not a time-limited trial. AppSheet's free tier is the most durable of the group: personal apps and prototypes stay free indefinitely for up to 10 test users, with no countdown attached.
How much do these app builders cost once you outgrow the free plan?
Checked on vendor pages in September 2026, entry paid plans start on AppSheet Starter (charged per user) and run up through $12/mo on Draftbit Standard, $18 to $19/mo on Thunkable Accelerator and Softr Basic (both billed yearly), similar entry pricing on Bolt Pro and Lovable Pro, $30/mo on v0 Plus, $36/mo on Adalo Starter, and $39/mo on FlutterFlow Basic. The real monthly cost still depends on the credits, records, or seats each plan includes.
Draftbit vs Bolt for a free app: which should I pick?
Pick Draftbit when you want a database-backed app with a visual editor and a Supabase backend, published free to draftbit.dev. Pick Bolt when the build is more prompt-to-code and you want real hosting attached immediately, accepting Bolt's branding on the free tier until you upgrade. See Bolt's alternatives for more prompt-first options.
Can I build a free app for internal use only, not the public?
Yes, AppSheet is built for exactly that: a free, permanent app for up to 10 named test users, never intended for a public launch. Softr's free plan also works for an internal pilot, with 5 app users and 5,000 database records total, though it lacks a custom domain until you upgrade to Basic.
What is the catch with these free app builder plans?
Most catches are a metered unit or a missing publish step, not a hidden price. Lovable and v0 reset their AI credits daily, so a heavy build session runs out fast. Adalo, Bubble, Glide, and Thunkable let you build for free but will not put the app live anywhere until you pay. AppSheet's free apps never go public. Reading the free plan's publish rule before you start avoids the surprise.
Do free app builder plans include a custom domain?
Rarely. Draftbit's free plan publishes to its own draftbit.dev subdomain, and FlutterFlow's free plan includes 2 free web subdomains, but neither includes a custom domain you own. Softr keeps the free plan on its own default subdomain instead of a custom one, and Adalo's free plan has no live address, custom domain or otherwise, until you pay for Starter.
