The best AI app builder depends on what you are building and how much of the code you want to touch. For a guided full-stack web app, start with Lovable or Base44; for the fastest prototype, Bolt; for a full cloud IDE, Replit; for native phone apps, FlutterFlow; and for chat plus the code, a database and hosting in one workspace, Mythex.

We compared 12 tools on how you build, what you get, who owns the code and what they cost as of October 2026. Mythex is our product, so it is listed first and labelled; we have described it with the same limits as everyone else.

The quick comparison

Prices change often. Every figure here is from the vendor's own pricing page or docs in October 2026; check before you pay.

What an AI app builder actually is

An AI app builder turns a description into a running app. You type what you want ("a booking page for my clinic with a calendar and email reminders"), and the tool writes the screens, the logic and often the database, then shows you a live preview. Most also host the result so you can share a link.

They differ in three ways that matter more than any feature list:

• How you change things. Some are chat-first (you keep describing changes), some are visual (you drag and configure), and some give you a full code editor. Many mix two of these.
• What runs behind the app. Some include a managed database and login; others expect you to connect your own services.
• Who owns the result. Code-generating tools usually let you export the code. Visual platforms often do not, because your app only exists inside their runtime.

If you are new to the category, what an AI app builder is explains it from scratch, and AI app builder vs. AI coding assistant covers where tools like Cursor fit.

1. Mythex: best for chat-to-code with a database and hosting in one place

What it is. Mythex (that's us) is an AI app builder made in Dubai, UAE. You describe the app in chat, in English, Arabic or any of the 69 languages the interface supports, using Build, Plan or Ask mode. It writes the code and runs it in a live preview inside a private cloud workspace with a code editor, file tree and terminal. The default stack is Vite, React, TypeScript and Tailwind; you can ask for Next.js, a static site, or a Python, Node, C# or Java API. A dedicated Postgres database and file storage are added when the app needs them, secrets are stored per project, and checkpoints let you roll back. You publish with one click to yourname.mythex.app or, on Pro, a custom domain.

Strengths.

• Chat, preview, code editor, terminal, database and publishing in one workspace, so there is no second account to set up for the basics.
• A clean exit: on Pro you can edit the code directly, export the project or sync it to GitHub.
• Arabic and right-to-left apps, including bilingual Arabic/English sites, are a first-class case rather than an afterthought.
• An MCP server, so Claude, Cursor or Codex can build in a Mythex workspace (MCP tool calls need Pro).
• Teams on Business get a shared workspace with roles, members-only published apps, Google Workspace SSO and required two-factor sign-in.
• Around 200 starting points in templates.

Limits. There is no visual point-and-click editor; you change things by chatting or editing code. Mythex builds web apps. On Pro it can turn a web app into Android and iPhone apps by wrapping it with Capacitor, but the screens are still your web app, not native UI built for each platform. Login and payments inside your app use your own provider and keys rather than a built-in managed auth product. Code editing, export, GitHub and custom domains need Pro.

Pricing as of October 2026. Free gives 5 credits a day (up to 30 a month), a read-only code view and publishing for up to 3 apps at once. Pro is $25/month or $250/year for 100 credits a month plus daily credits, with full code editing, export, GitHub sync and custom domains. Business starts at $50/month and Enterprise at $680/month. Members are unlimited with no per-seat fee. See Mythex plans or pricing.

Who should pick it. Founders and small teams who want to describe a web app, keep the code, and not assemble hosting and a database themselves; and anyone building in Arabic. If you want to click and drag on the page, pick Lovable, Base44 or Bubble instead.

2. Lovable: best for guided full-stack web apps

What it is. Lovable describes itself as a full-stack AI development platform for web applications. You chat, it builds the frontend, backend, database and login, and you can refine on the preview: its toolbar lets you select elements and edit text inline. Its backend, Lovable Cloud, is built on Supabase's open-source foundation and includes a database, storage, authentication and functions.

Strengths. A polished guided path for non-developers, a backend that works without a second account, Git sync, and on-preview editing for small visual changes. Plans are priced by credits rather than seats, and workspaces allow unlimited members.

Limits. Web apps only. Code editing, custom domains and removing the "Edit with Lovable" badge are paid features, and SSO is on Business. The managed backend is convenient but ties the running app to Lovable Cloud unless you move it.

Pricing as of October 2026. Free gives 5 build credits a day, up to 30 a month. Pro starts at $25/month for 100 credits and Business at $50/month, with higher credit tiers on both; paid plans also get daily build credits. See Lovable's plans.

Who should pick it. Non-technical founders and designers who want a full-stack web app and like to tweak things visually. If on-preview editing is what you want most, Lovable is the better pick over Mythex. More: Mythex vs Lovable and Lovable alternatives.

3. Bolt: best for fast prototypes in the browser

What it is. Bolt, from StackBlitz, is an AI builder for websites, web apps and mobile apps that runs in your browser on WebContainers. It builds with JavaScript-based frameworks; mobile apps go through its Expo integration, and Bolt's docs describe distributing them through TestFlight and the App Store with your own developer accounts. Bolt Cloud adds hosting, databases and custom domains.

Strengths. Very quick to a first running preview because the runtime is the browser tab. Broad choice of frontend frameworks, hosting and databases included, and connectors and MCP on Pro.

Limits. Token use grows with project size. Backends stay in the JavaScript world. Free sites carry Bolt branding and cannot use a custom domain.

Pricing as of October 2026. Free gives 1M tokens a month with a 300K daily limit. Pro is $25/month for 10M tokens, with rollover, custom domains and no Bolt branding. Teams is $30 per member per month. Yearly billing saves up to 28%. See Bolt pricing.

Who should pick it. Anyone who wants a working prototype or demo quickly, and JavaScript developers who like seeing the code. More: Mythex vs Bolt and Bolt alternatives.

4. Replit: best for a full cloud IDE with an agent

What it is. Replit is a cloud development environment with an AI Agent that builds apps and sites from a description, with built-in authentication, database, hosting and monitoring. It supports many languages and several deployment types, including always-on and scheduled ones. Replit's docs describe building mobile apps with Expo and publishing them to the App Store through a Launch wizard, with the build compiled on Expo's servers and an Apple Developer membership required.

Strengths. The broadest runtime in this list: long-running servers, scheduled jobs, bots and many languages, plus a real IDE when you want it. Pro adds parallel agents and up to 15 collaborators.

Limits. The IDE is always there, which can feel like a lot for non-developers. Agent and hosting usage are metered, so the plan price is a floor rather than a ceiling.

Pricing as of October 2026. Core is $20/month ($18 billed annually). Pro is $100/month ($90 billed annually) with up to 15 collaborators and 50 viewers. Enterprise is custom. See Replit pricing.

Who should pick it. Developers and technical founders who want one cloud machine for everything, and anyone who needs background workers or scheduled jobs. More: Mythex vs Replit and Replit alternatives.

5. v0: best for UI and Next.js apps on Vercel

What it is. v0 is Vercel's AI agent for building UI and full-stack apps with Next.js, Tailwind CSS and shadcn/ui. Apps deploy to Vercel, and it has GitHub sync and a visual Design Mode.

Strengths. Strong interface generation, and a direct path into Next.js repositories and Vercel hosting that many engineering teams already use.

Limits. Databases and other services come through integrations rather than one built-in product, and the natural home is Vercel. Paid plans are per user, which adds up for larger teams.

Pricing as of October 2026. Free has a 7-message daily limit, and new users get $5 in one-time credits. Plus is $30 per user per month and Business $100 per user per month, each with $30 of monthly credits per user plus daily login credits. See v0 pricing.

Who should pick it. Teams already on Vercel and Next.js, and designers or engineers who mainly need UI to drop into an existing codebase. More: Mythex vs v0 and v0 alternatives.

6. Base44: best for the fewest infrastructure decisions

What it is. Base44 is a no-code AI platform that builds apps and websites from a prompt, with a managed backend, authentication, integrations and hosting built in, plus a visual editor.

Strengths. Backend, auth and hosting are there from the start, so there are very few choices to make. Paid plans add in-app code edits and custom domains; GitHub integration starts at Builder.

Limits. The free tier is small, and code-level access is gated to paid plans. As of October 2026 its docs describe submitting apps to the App Store and Google Play in a web-view wrapper, with the store files on the Builder plan and up.

Pricing as of October 2026. Free gives 25 message credits a month. Billed annually, Starter is $16/month (100 message credits), Builder $40/month (250), Pro $80/month (500) and Elite $160/month (1,200); annual billing saves 20% over monthly. See Base44 pricing.

Who should pick it. People who want the fewest infrastructure choices and a visual editor alongside chat. More: Mythex vs Base44 and Base44 alternatives.

7. Bubble: best for visual programming on web and native

What it is. Bubble is a long-running no-code platform that pairs AI prompting with its visual editor. It builds full-stack web apps and native iOS and Android apps, with hosting included.

Strengths. Deep visual control over workflows, data and privacy rules without reading code, and web plus native mobile from one platform.

Limits. Bubble's documentation says apps run only on Bubble and cannot be exported as code; if you leave, you rebuild the logic. Usage is metered in workload units, and the learning curve is real. Deploying a live mobile app needs a paid plan.

Pricing as of October 2026. Free includes 50K workload units a month. Billed annually, Starter is $59/month (175K WU), Growth $209/month (250K) and Team $549/month (500K). See Bubble pricing.

Who should pick it. People who never want to see code and will learn a visual programming model in exchange for control. More: Mythex vs Bubble and Bubble alternatives.

8. FlutterFlow: best for native mobile apps with a visual editor

What it is. FlutterFlow is a visual builder for mobile, web and desktop apps built on Flutter, with AI generation, Firebase and Supabase integrations, and one-click app store deployment on paid plans.

Strengths. One of the clearest paths in this list to native apps in both stores, with downloadable Flutter code from Basic and GitHub integration from Growth.

Limits. It is a visual builder first; AI requests are capped per plan (5 lifetime on Free, 50 a month on Basic). Expect to learn its editor and some Flutter concepts.

Pricing as of October 2026. Free, then Basic $39/month, Growth $80/month for the first seat and $55 for the second, and Business $150/month for the first seat. Annual billing saves about 25%. See FlutterFlow pricing.

Who should pick it. Anyone whose product must be a native phone app today and who is happy to work visually. More: FlutterFlow alternatives and Bubble vs FlutterFlow.

9. Anything: best for prompt-to-phone-app with Expo

What it is. Anything builds mobile apps, websites and tools from plain-language descriptions. Its docs say it generates Expo (React Native) code, previews the app in a device frame or on your phone through Expo Go, and submits to the App Store through TestFlight; Google Play publishing is in beta and uploads to the internal testing track.

Strengths. A chat-first route to a real phone app, with an App Store review check before submitting and the code visible in Code mode.

Limits. You need an Apple Developer account ($99/year, per its docs) for the App Store. Google Play support is still in beta. Credits are consumed per build, so heavy iteration costs more.

Pricing as of October 2026. Pro is $19/month for 20K credits, with custom domains and no Anything branding; a $199/month tier adds more credits. A free plan is mentioned. See Anything pricing.

Who should pick it. Non-developers who want a phone app from chat and are fine with an Expo-based stack. More in the best AI mobile app builders.

10. Zite: best for business apps with unlimited users

What it is. Zite is an AI app builder for business software: internal tools, internal and external portals, dashboards, websites and automated workflows. It includes a built-in Postgres database you can export, user authentication with roles, integrations such as Salesforce, and MCP access from Claude, ChatGPT and Cursor.

Strengths. Every plan lists unlimited users, which matters for portals with many outside users. Paid plans remove Zite branding, and Business adds white-label emails and unlimited custom domains.

Limits. It is aimed at business apps rather than consumer products. SSO is listed for Enterprise only, and database records are capped per plan (5,000 on Free).

Pricing as of October 2026. Free with 50 credits. Pro is $20/month billed annually ($240/year) with 100 credits and one custom domain; Business is $75/month billed annually with 400 credits. See Zite pricing.

Who should pick it. Teams building client portals and internal tools for a lot of users who would otherwise pay per seat.

11. Softr: best for client portals on your existing data

What it is. Softr builds client portals and internal tools — CRMs, intranets, trackers, forms and dashboards. Its AI Co-Builder creates the database, pages, user roles and logic from a description, and you keep editing with visual controls. It has its own Softr Databases and connects to Airtable, Notion, Google Sheets and others on every plan, with SQL databases, HubSpot and BigQuery on higher tiers.

Strengths. Mature user groups and record-level permissions, several login methods (email and password, one-time codes, Google sign-in, magic links), and a large set of data connectors.

Limits. Some data sources, custom user groups and two-factor authentication are gated to higher plans. It is a block-based builder, so you do not get the generated code.

Pricing as of October 2026. Softr has a free plan; paid plans are listed on Softr's pricing page.

Who should pick it. Teams whose data already lives in Airtable, Sheets or a CRM and who need a portal on top of it. More: Mythex vs Softr and Softr vs Glide.

12. Glide: best for spreadsheet-based internal apps

What it is. Glide builds internal business apps and AI agents on your company's data. It starts from Excel and Google Sheets and connects to databases and tools such as Salesforce and NetSuite. Apps work on desktop and phone.

Strengths. Very fast from a spreadsheet to a usable app for a team, with AI features you can use inside apps. Pro adds bring-your-own-agent over MCP and org-level roles.

Limits. Free cannot publish apps. Plans cap team members and published apps (2 published apps on Basic), and annual plans were listed as coming soon.

Pricing as of October 2026. Free, Basic $25/month, Plus $50/month and Pro $125/month. See Glide pricing.

Who should pick it. Operations teams turning a spreadsheet into an app quickly. More: Glide alternatives.

What about Cursor and other AI coding tools?

Cursor, GitHub Copilot and Claude Code are not app builders: they are AI assistants for developers working in a codebase, usually on their own machine, and you provide the hosting and database. As of October 2026 Cursor lists a free plan, individual plans from $8 to $200 a month and Teams from $30 per user per month (Cursor pricing). If you are a developer with an existing repository, one of these may serve you better than any builder above. You can also combine them: Mythex's MCP server lets Cursor or Claude build inside a Mythex workspace. See Cursor alternatives and AI app builders with MCP.

How we compared

This is a comparison of publicly stated features and pricing, not a hands-on benchmark. We read each vendor's own pricing page and documentation in October 2026 and compared them on:

• How you build — chat, visual editor, code editor, or a mix
• What you get — frontend only, or backend, database, login and hosting too
• Ownership — can you edit, export or sync the code
• Mobile — web apps only, a wrapped web app, or native iOS and Android
• Pricing — the free tier, the first paid tier, and how usage is metered (credits, tokens, seats or workload units)

We did not run timed tests, and we avoid claims about output quality that we cannot link to. Where a vendor's page did not state something, we say so instead of guessing. Mythex is our product; we listed it first because it is our site, and we have described its limits as plainly as anyone else's.

Which one should you choose?

Start from the constraint that matters most.

You are a non-technical founder building a web app. Lovable, Base44 or Mythex. Pick Lovable or Base44 if you want to edit visually on the page; pick Mythex if you want the code, a terminal and a database in the same workspace, or if the app is in Arabic.

It must be a native app in the App Store. FlutterFlow if you are happy to build visually; Anything or Rork if you want to prompt an Expo app; Bubble if you also need a web version from the same platform; Replit if you are a developer. If a web app inside a phone shell is enough, Mythex can wrap your web app for Android and iPhone on Pro. The full breakdown is in the best AI mobile app builders.

You want the fastest throwaway prototype. Bolt, or v0 if it is mostly UI.

You need background workers, cron jobs or many languages. Replit.

Your team is already on Vercel and Next.js. v0.

You are building a client portal or internal tool on existing data. Softr or Glide if the data lives in spreadsheets or Airtable; Zite if you will have many users; Mythex if you want custom code and your own database. See how to build a client portal and the best AI app builders for agencies.

You need dashboards. For BI on a data warehouse, a dashboard tool is usually better than an app builder; for a custom dashboard inside your own product, an app builder works well. See the best dashboard software.

You never want to see code. Bubble, Base44, Softr or Glide.

You are a developer with an existing repository. Cursor or another AI coding assistant, possibly connected to a builder over MCP.

How to test an AI app builder before you pay

Free tiers are small, so use them on a test that tells you something. A good one takes an hour:

1. Build one real slice. A form that saves to a database and a page that lists what was saved, with a detail view. This touches the frontend, the data model and the backend.
2. Ask for a change that crosses screens. "Add a status field and filter the list by it." Watch whether the tool updates everything consistently or breaks the other screens.
3. Look at what you can see. Can you read the code? Can you see the database tables? Can you roll back a bad change?
4. Publish it. Open the link on your phone. Check that it loads, looks right and works without you signed in.
5. Check the exit. Find where export, GitHub sync or data download lives, and which plan it needs.
6. Read the meter. After the hour, look at how many credits, tokens or messages you used. Multiply by how much building you expect to do in a month.

Run the same test on two or three tools and the right one is usually obvious. Our guide to writing prompts for AI app builders covers how to phrase requests so the comparison is fair.

Costs that do not show on the pricing page

The headline price is rarely the bill. Watch for:

• Usage meters. Credits, tokens, messages and workload units all run out at different speeds. Big projects use more per change on token-metered tools.
• Hosting and database usage. Several tools bill hosting, bandwidth or storage separately from building, or from a separate allowance.
• Seats. Per-user plans (v0, Bolt Teams, extra FlutterFlow seats) grow with the team; credit-priced plans with unlimited members (Lovable, Mythex) do not.
• Store fees. Native apps need an Apple Developer membership and a Google Play developer account, on top of any builder plan.
• Third-party services. Payments, email sending, maps and AI APIs are usually billed by their own providers.

How much it costs to build an app works through a realistic budget.
