Lovable is an AI app builder that turns plain-language chat prompts into working full-stack web applications, generating React, TypeScript, and Tailwind CSS code with an optional built-in backend called Lovable Cloud. Founded in 2023 in Stockholm, it lets non-technical founders and developers build, iterate, and publish real software without writing code by hand — though production-grade apps still typically need manual polish for the last stretch.

Why "AI app builder" undersells what Lovable actually does
Most people hear "AI website builder" and picture a drag-and-drop tool with an AI assistant bolted on. Lovable is closer to a junior full-stack engineer that lives in your browser: you describe a feature in a chat panel, and it writes, runs, and previews real code — the same React and TypeScript a human developer would write, not a proprietary block format you're locked into. Under the hood, Lovable's builder runs on Anthropic's Claude models through an agent harness that can spin up subagents for different parts of a task, rather than a single raw LLM call. Anthropic's own case study on Lovable credits Claude Opus 4.5 with a step change in reliability on long, multi-step builds, and Lovable has been testing newer Claude generations (including Sonnet 5) against its hardest real-world pull requests. There is no model picker in the product — Lovable routes the work internally and doesn't publish which exact model version is live at any given moment. What comes out the other end is a genuine Vite or TanStack Start React application (TanStack Start with full server-side rendering is now the default for new projects created from May 13, 2026 onward; older projects remain client-rendered Vite single-page apps unless upgraded), styled with Tailwind CSS, wired up to shadcn/ui components, and — if you turn it on — backed by Lovable Cloud, a managed Supabase instance built directly into the editor.
- It writes real, exportable React/TypeScript code — not a locked proprietary format
- It runs on Anthropic Claude models orchestrated through an agent harness, not one raw LLM call
- Lovable Cloud bundles a managed Supabase backend directly into the editor, no separate signup required
- Two work modes — Plan Mode for scoping, Build (Agent) mode for execution — control how and when changes get made
Before you start
- A free Lovable.dev account (email, Google, or GitHub sign-in)
- A clear one- or two-sentence description of what you want to build
- For backend features: willingness to connect Lovable Cloud or your own Supabase project
- For custom domains, private projects, or code downloads: a Pro plan or higher
How to fix it
Describe what you want to build in plain language
Lovable is prompt-first: the entire workflow starts from a natural-language description, not a template picker or a canvas
You sign up (email, Google, or GitHub) and land on a chat box asking what you want to build. You can type something as simple as "a waitlist landing page for a fitness app" or as detailed as a multi-paragraph spec. Lovable's agent reads the request, decides what pages, components, and (if needed) database tables it implies, and starts generating a first working version — usually visible in the live preview within a minute or two.
Expected result: A working first draft of your app in the preview pane, with a chat history you can keep building on.
Lovable's agent writes and runs the code in Build mode
Build mode (the default "Agent" mode) is what actually edits files, installs dependencies, and fixes its own errors, rather than just chatting about the app
In Build mode, every message you send can create, edit, or delete files in the project — React components, Tailwind classes, TypeScript types, Supabase queries if Cloud is connected. The agent runs a build after each change and attempts to fix errors it introduces before showing you the result. This is also where most of your credit usage happens: simple edits cost a fraction of a credit, larger features (adding auth, a new database table, a payment flow) cost more.
Expected result: Code changes applied directly to the project, with the live preview updating automatically.
Use Plan Mode before big or risky changes
Plan Mode is read-only, so it lets you and the agent agree on an approach before any code is touched — cheaper than undoing a wrong turn
Switch to Plan Mode (next to the chat input) and describe a bigger feature — say, a full checkout flow. Lovable analyzes the existing codebase and returns a structured plan: which files it will touch, what the data model looks like, what edge cases it's accounting for. Nothing changes in your project until you approve it and Lovable switches into Build mode to implement it. Plan Mode messages cost 1 credit each, though Lovable can spin up research subagents that add to that cost for complex plans.
Expected result: A written plan you can review, edit the wording of, and approve — before a single line of code changes.
Connect Lovable Cloud for auth, database, and storage
Most real apps need a backend, and Lovable Cloud lets the agent wire one up without you leaving the editor or managing a separate Supabase project
Open the Cloud tab (the "+" icon next to the preview) and you'll find Database, Users & Auth, Storage, Edge Functions, AI, Secrets, Logs, and Usage sections. Prompting for "user login" or "a table to store orders" causes Lovable to generate the schema, Row Level Security policies, and auth flow through Cloud automatically. Lovable Cloud is managed Supabase under the hood and is not visible in your own separate Supabase dashboard — if you later need direct database access outside Lovable, you connect your own Supabase project instead.
Expected result: A working database, auth flow, or file storage bucket, manageable from the Cloud tab without external tools.
Publish, connect a custom domain, and sync to GitHub
A working preview isn't a live product — publishing and version control are what make the app usable and safe to keep iterating on
Clicking Publish (top right) pushes the current version live on a free yourapp.lovable.app subdomain on every plan; a custom domain requires a paid plan. For version control, connect GitHub (or GitLab) under Settings then Connectors — this creates a two-way synced repository, so every Lovable change becomes a commit and you can also push code from outside Lovable and have it pulled back in. Renaming or deleting the connected repo breaks the sync, so treat it as fixed once connected.
Expected result: A live, publicly reachable app plus a GitHub repository with full commit history as a safety net.
Know what Lovable is not good at (and who should hire out the rest)
Being honest about the limits saves you from shipping something fragile or burning credits chasing a bug the agent can't see
Lovable is genuinely strong at getting an idea to a working 60-80% state fast. Where it struggles: the last 20-30% of polish and edge cases, debugging loops where the agent repeats the same failed fix, credit burn on complex multi-system features, and anything that needs true native mobile output (Lovable produces web apps, not App Store binaries). For teams that need production hardening, security review, or the final mile done right, RapidDev's engineers pick up exactly where Lovable's agent starts to struggle, working directly in your existing project and GitHub repo.
Expected result: A realistic sense of when to keep prompting solo and when to bring in a developer for the finishing work.

- Start with a single, clear prompt describing the core feature, then iterate in small steps
- Use Plan Mode before any change that touches multiple files or the database schema
- Connect GitHub from the first session so every change is version-controlled and reversible
- Treat the free tier as a prototyping sandbox, not a production plan — public projects only, capped daily credits
- Read the auto-generated database schema and Row Level Security policies before publishing anything with real user data
- Budget for a Pro or Business plan once you need custom domains, code downloads, or private projects
- Expect to hand off the last 20-30% of a serious app — edge cases, hardening, performance — to manual review or a developer
Still stuck?
Copy one of these prompts to get a personalized, step-by-step explanation.
I'm evaluating whether to build my app idea in Lovable.dev, an AI app builder that generates React/TypeScript apps with an optional Supabase backend from chat prompts. Here's my idea: [describe your app]. Help me figure out: 1) whether this is a good fit for a prompt-based builder versus custom code, 2) what backend features (auth, database, payments, file storage) I'll realistically need, and 3) a rough plan for the first three prompts I should send to Lovable to get a solid first version.
Explain the current structure of this project: what pages, components, and database tables exist, and how they connect to each other. Check whether Row Level Security is enabled on every Supabase table this project uses, and flag any tables that aren't protected. List any TODOs, placeholder content, or clearly incomplete features you can find in the code.
Frequently asked questions
Where can I find Lovable's official documentation?
At docs.lovable.dev, which covers features, integrations, pricing, and troubleshooting, plus an AI-powered docs assistant you can chat with directly on the site.
Does Lovable have a blog?
Yes, at lovable.dev/blog. It covers product launches (like Lovable 2.0 and Plan Mode), engineering deep dives, and major company announcements including funding rounds.
Is there an official Lovable Discord or community?
Yes, lovable.dev/discord hosts a community of 160,000+ builders. It's explicitly peer-to-peer help, not an official support channel — for account, billing, or platform issues, go through in-app support or email instead.
Does Lovable run hackathons?
Lovable has sponsored and participated in community hackathons, but as of September 2026 there's no standing, published hackathon program on lovable.dev — treat any specific event as ad hoc rather than a recurring offering.
What was "Lovable 2.0"?
A major relaunch on April 24, 2025: a new brand and UI, multiplayer workspaces, Chat Mode (the predecessor to today's Plan Mode), a Security Scan for Supabase-connected apps, Dev Mode for code editing (now called the Code tab), Visual Edits, and built-in custom domain purchasing.
Is Lovable free to use, or do I need to pay?
There's a genuine free tier: 5 daily build credits (capped at 30/month) plus small monthly Cloud and AI credit grants, but free projects are public-only with no custom domain or code download. Paid plans start at $25/month for Pro.
What does the Lovable logo look like?
A simple heart-based icon in Lovable's signature color palette, used consistently across the editor, marketing site, and published-app badge ("Edit with Lovable").
What if I outgrow what Lovable can build on its own?
That's normal for anything beyond an MVP — most serious products need a developer for the final 20-30%. RapidDev's engineers work directly inside existing Lovable projects and GitHub repos to harden, extend, or scale apps that started in Lovable.
