Best AI App Builders in 2026 (Lovable, Bolt, v0, Replit and More)

The Short Answer

You want to go from a sentence to a working app, and every vendor promises exactly that. The differences show up after the first demo: what the plan really costs, whether the backend is real, whether you can point your own domain at it, and whether you can take the code and leave. Lovable is the best all-round pick for web apps with a managed backend. Bolt.new is the best budget start and the clearest path to a native mobile app. v0 wins for Next.js on Vercel. Replit Agent is the most complete single product. All prices in this guide are as of Nov 11, 2026, taken from each vendor's own pages.

One framing note. These tools are prototyping accelerators first and production hosts second. Most serious teams generate the first version here, push it to GitHub, and continue in a coding agent. If that second stage is your real question, read our guide to the best AI coding agents in 2026.

Quick Picks

Master Comparison Table

Prices are USD, as of Nov 11, 2026, from each vendor's pricing or docs page. Where a page did not state something, the cell says so instead of guessing. Credit units are not comparable across vendors: a Lovable credit, a Bolt token and a Replit dollar of credit measure different things.

None of these is open source. If open-source and self-hosted is a hard requirement, the category you want is coding agents rather than app builders.

Lovable

Lovable is a chat-driven builder that generates both the frontend and the backend. Its built-in backend, called Cloud, includes a database, authentication, storage and edge functions, plus realtime updates, scheduled jobs, secrets and logs. The docs say Cloud builds on Supabase's open-source foundation, and you can connect your own Supabase project instead. Lovable's docs do not name the framework of generated apps, so I will not either.

Pricing (as of Nov 11, 2026). Free gives 5 build credits a day, capped at 30 a month, plus 20 Cloud credits and 4 AI credits. Pro starts at $25 a month for 100 credits ($250 a year, about $21 a month). Business starts at $50 a month for 100 credits. Both scale up to 10,000 credits, where Pro is $2,250 a month. Verified students and teachers get 50% off Pro for up to 12 months. Monthly plan credits expire two months after issue, and top-ups last 12 months.

Strengths. GitHub, GitLab and Bitbucket sync is available on every plan, including Free. Custom domains, code editing and download, design systems and removal of the Edit with Lovable badge start at Pro. Workspaces allow unlimited members on all plans and price by credits rather than seats, which suits small teams.

Weaknesses. The Free plan blocks custom domains and code download, so you cannot fully evaluate the exit path before paying. Credits are consumed by debugging loops as well as by new features. I found no mobile build path in the Lovable docs I fetched, so treat mobile as unverified.

Best for: founders and product managers who want a managed full-stack web app and a clean GitHub handoff.

Bolt.new

Bolt.new runs in the browser and now includes Bolt Cloud: a built-in database with authentication settings and file storage, hosting with publish and domain guides, and an optional Supabase connection on Pro and Teams plans. It offers a choice between Standard and Max agents.

Pricing (as of Nov 11, 2026). Free is $0 with 1M tokens a month and a 300K daily limit, no rollover, a 10MB upload limit and Bolt branding on published sites. Pro is $25 a month, starting at 10M tokens, with no daily limit, rollover, 100MB uploads, custom domains, private site sharing and SEO boosting. Teams is $30 per member a month and adds centralized billing, admin controls and private NPM registry support. Yearly billing saves up to 28%, though yearly prices are not listed. Hosting is separate: Free allows 10 GB bandwidth and 333,333 requests a month with a hard stop, and Pro hosting, included with every paid plan, allows 30 GB and 1 million requests.

Strengths. A large free token budget (1M a month), and the most detailed Expo path to the stores in this list (see the Mobile section). The help center documents project download, rename, duplicate and transfer, plus GitHub integration.

Weaknesses. Token billing is harder to predict than message billing. The help center warns that web projects do not easily switch over to mobile, so decide on mobile in your first prompt. Free hosting goes offline at the limit and stays offline until the next billing cycle.

Best for: cost-sensitive builders, and anyone aiming at an iOS and Android app from day one.

v0 (Vercel)

v0 describes itself as an agent that builds production-ready code, full-stack apps and agents from natural language. It generates Next.js, React and shadcn-based projects, connects to databases including Supabase and Neon, deploys to Vercel infrastructure, supports custom domains and syncs with GitHub. The docs also mention mobile support without detail, so I treat it as unverified.

Pricing (as of Nov 11, 2026). Free is $0 with a limit of 7 messages a day, Vercel deploys, Design Mode and GitHub sync. Plus is $30 per user a month with $30 of included credits, $2 of free daily credits on login and access to all models. Business is $100 per user a month with training opt-out by default. Enterprise adds SAML SSO and guaranteed support SLAs. New users get $5 in one-time credits.

Strengths. The cleanest fit if your production target is Vercel. GitHub sync on the free plan means the code never feels locked in.

Weaknesses. It leans frontend. You wire your own database and auth through integrations rather than getting a managed backend from the builder itself, and per-user pricing climbs fast for teams.

Best for: designers and engineers who already deploy on Vercel and want UI-heavy Next.js output. If you route models through Vercel, our MCP servers guide covers what to plug in next.

Replit Agent

Replit started as a browser IDE and now wraps an agent, a database, auth, publishing and mobile tooling in one workspace on web, desktop and mobile. Its docs have dedicated pages for adding a database, adding login, publishing, custom domains, domain purchase and connecting a GitHub repository.

Pricing (as of Nov 11, 2026). Core is $20 a month ($18 billed annually) with $20 toward more powerful models, up to 30 hours of chat on Free Mode and unlimited workspaces. Pro is $100 a month ($90 annually) with $100 toward the most powerful models, $100 in credits, up to 15 collaborators and database rollback up to 28 days. The page also lists higher Pro price points ($215, $425, $825 and $2,000) without saying what they include. Publishing is metered: Autoscale has a $2 monthly base plus $0.60 per million compute units and $0.40 per million requests; Reserved VM runs from $15 to $130 a month; Static hosting is free with $0.05 per GB transfer. Publishing costs come out of your monthly credits and unused credits do not roll over. The Starter plan includes one free published app that expires after 30 days but can be republished.

Strengths. Breadth. One account covers build, data, auth, hosting and an App Store submission flow. Plan and Build modes let you review a plan before the agent edits files.

Weaknesses. Two meters (agent credits and deployment usage) make monthly cost hard to forecast. The docs index lists no dedicated code export page; the closest are GitHub connection and workspace copy pages, so verify your exit path before committing.

Best for: solo builders who want one environment from prompt to published app, including mobile.

Base44

Base44 targets non-technical builders and ships a managed backend from the first prompt. Its docs cover entities (the data model) with row- and field-level security rules, backend functions, automations, login and registration, SSO and backups. The Free plan already includes authentication, database functionality and analytics.

Pricing (as of Nov 11, 2026, billed annually). Free: 25 message credits and 100 integration credits a month, up to 5 apps. Starter: $16 a month, 100 message credits, connect a domain, free domain for one year. Builder: $40 a month, 250 credits, adds AI model select and GitHub integration. Pro: $80 a month, 500 credits. Elite: $160 a month, 1,200 credits and premium support. Annual billing saves 20%. The page says exact usage varies by action and model, so credits are not a fixed unit.

Strengths. The most backend-complete free plan here, with sensible security primitives for internal tools and portals. Domain connection includes buying a domain through Wix.

Weaknesses. Code export to GitHub or ZIP requires the Builder plan or higher, so the cheapest paid tier does not give you the exit. Base44's own GitHub connector page covers calling the GitHub API from your app, and points to Base Code for syncing app code to a repository. And its mobile output is a web wrapper (see Mobile).

Best for: business users building internal tools, dashboards and portals who want security rules without writing a backend.

Anything (Create)

Anything, which this guide treats as the product formerly branded Create, says it turns words into mobile apps, sites, tools and products built with code, with GPT-5 and 40+ integrations. Beyond that headline, the pages I could fetch do not describe the stack, backend, database or auth, so I cannot compare it on those axes.

Pricing (as of Nov 11, 2026). Pro is $19 a month for 20K credits with private projects, removal of Anything branding, custom domains, unlimited projects and messages, and 50 GB storage. Max is $199 a month for 200K credits and adds parallel agents, visual QA with a computer-use agent, 1M context, automated testing, 150 GB storage and priority support. The page lists Submit to App Store in its comparison table without saying which plan includes it, and does not mention GitHub.

Strengths. The cheapest paid entry in this list, and automated testing plus visual QA at the top tier is a distinctive angle. Weaknesses. Thin public documentation on what it generates. Best for: small founders who want a low-cost paid tier with a mobile focus and are willing to test the output themselves.

Emergent

Emergent markets itself as an agentic platform that designs, codes and deploys apps from a description, covering web apps, mobile apps and dashboards, with databases and APIs preconfigured, built-in hosting and GitHub integration. The homepage does not name a stack. It also states you own the generated code and can host it anywhere, and claims SOC 2 and ISO 27001; those are vendor claims I did not test.

Pricing (as of Nov 11, 2026). Free: 10 monthly credits, with web and mobile builds. Standard: $17 a month billed annually ($20 otherwise) for 100 credits a month, GitHub and private project hosting. Pro: $167 a month billed annually ($200 otherwise) for 750 credits, a 1M context window, ultra thinking, system prompt editing and custom AI agents. Business and Enterprise are custom, with SSO, role-based access, real-time co-editing and, for Enterprise, deployment in your own VPC.

Strengths. A free tier that includes mobile builds, and an enterprise path that includes self-hosted databases. Weaknesses. The big jump from $17 to $167 mirrors Replit's and Anything's shape, and the free tier's 10 credits will not finish a real app. Best for: founders who want web and mobile from one prompt and may later need a private-cloud option.

Rocket

Rocket builds websites, landing pages, web apps and mobile apps, with staging and production environments and one-click deploy. It can pick up an existing Next.js project and continue it, and connectors link internal systems and APIs. Its homepage names no backend platform and no export path, so those stay unverified. It states SOC 2, ISO 27001, GDPR, CCPA and SSO/SAML support, which are vendor claims.

Pricing (as of Nov 11, 2026). Free includes 20 one-time credits. Pro is $25 a month for 100 credits, Rocket is $50 for 250 and Booster is $250 for 1,500. All plans have unlimited team members with no per-seat fees, credits never expire according to the page, and annual billing saves 20%.

Strengths. No per-seat pricing, and credits that carry forward. Weaknesses. The free tier is a one-time grant, not a monthly one, and public detail on stack and export is thin. Best for: small teams that want shared access without seat costs, and agencies shipping marketing sites and portals.

Google AI Studio Build

Build mode in Google AI Studio creates web apps or native Android apps from natural language. Web apps use React on the frontend and a Node.js server-side runtime that supports secure API calls, database connections and npm packages. Android apps use Kotlin and Jetpack Compose. For web apps the agent can set up Firestore and Firebase Authentication, including Sign in with Google. You publish to Cloud Run, and custom domains require a paid Google Cloud project.

GitHub support is two-way: import an existing repository or link one in Settings, with AI-generated commit messages and a conflict-resolution dialog. The docs do not describe a free tier or list prices. They note that paid models and Cloud Run usage may be billed, and API calls from shared apps count against your usage limits. There is no real-time collaborative editing, and direct storage support is planned but not yet available.

Best for: teams already on Google Cloud and Firebase, and anyone who wants a real Kotlin Android app from a prompt. The Antigravity setup guide covers Google's code-first IDE, the other half of its migration story.

Firebase Studio

Firebase Studio is on this list as a warning. It offered an App Prototyping agent powered by Gemini, a Code OSS-based IDE, Firestore and Firebase Authentication setup, and deployment to Firebase App Hosting and Hosting. Per Google's docs, the sunset was announced on March 19, 2026, new workspace creation and signup were disabled on June 22, 2026, and Firebase Studio shuts down on March 22, 2027, when remaining data is permanently deleted. Google points app-prototyping users to Google AI Studio and code-first users to Google Antigravity. Firestore and Authentication are not affected. Do not start anything new here.

Same

Same began as a site-cloning agent and, according to third-party reviews, now builds apps from prompts on a monthly token model. I could not verify any of that first-hand: both same.new and same.dev refused connections from my test machine on Nov 11, 2026, and the aggregator pages disagree on pricing. That is why Same is the one row in the table with no numbers. Check the vendor directly before you rely on it.

Backend, Deploy and Export Compared

The real split is how much of the backend the builder owns. Lovable Cloud, Bolt Cloud, Replit, Base44 and Emergent ship a managed data layer. v0 connects you to Supabase or Neon and runs on Vercel. Google AI Studio Build leans on Firebase and Cloud Run. The cost of a managed backend is coupling: the more of it the builder hosts, the more work a migration becomes, even when the generated code exports cleanly.

Before you commit to any of them, run a short exit test: generate a small app, sync it to GitHub, clone it, and try to run it locally. If it does not start, you have learned the real lock-in cost for the price of one prompt. For the next step after export, see our AI agent hosting platforms guide, and for a retrieval layer behind an AI feature see best vector databases for AI agents.

Mobile

Mobile claims deserve the most skepticism, because “works on a phone” covers three very different things.

Bolt documents the Expo flow in the most detail. A snippet from its help center for the web export of a mobile project:

npx expo export --platform web
eas deploy --prod

One constraint from Bolt's docs is easy to miss: you cannot change the app slug after the first build. Replit has the same kind of rule for the bundle ID. Pick both on purpose.

Benchmarks and Independent Data

There is no neutral, widely accepted leaderboard for prompt-to-app builders. Output quality depends on the prompt, the underlying model, which agent mode you pick and how many iterations you pay for, and vendors change all of those weekly. The search results I saw were mostly vendor-published or affiliate-style comparisons, and one popular comparison guide was published by Lovable itself, so I did not use any of them for rankings. The only numbers in this guide are prices and limits from vendor pages, and the only claims about quality are the ones I label as vendor-reported. If you need evidence, run the same prompt on two or three tools on their free tiers and compare the output.

How to Choose

If the generated app will run user-submitted code or agents, put it behind isolation; our AI agent sandboxes guide covers the options.

How We Evaluated

Every price, limit and feature in this guide comes from the vendor's own pricing or documentation page, fetched on Nov 11, 2026. Where a page was silent, the guide says so. Where a page could not be reached (Same), the entry is marked unverified. I did not run generation tests for this edition, so there are no first-hand quality claims. There is no paid placement and no affiliate link in this ranking. Prices change often, so confirm on the vendor page before buying.
