Lovable AI builds a complete web app from a description written in plain language. On its website, Lovable claims you can work up to 20 times faster than with manual coding, and its demo shows a Wordle clone built in two minutes. Both figures come from the vendor.
This approach, known as vibe coding, lets you describe your app instead of coding it. You get a site with authentication, a database and online payments without any programming skills.
Lovable AI: definition and how it works
The Lovable team sums up its ambition in one line: to build "the last piece of software", a tool that generates all the others. You describe an app idea in English or French, and you get a working product without writing a single line of code.
Where Lovable came from
The story begins in mid-2023 with GPT-Engineer, an open source project exploring AI-driven software generation. The repository became one of the most followed on GitHub, with more than 50,000 stars. Anton Osika and his team then founded Lovable with a broader mission: to let anyone turn an idea into a business.
The name Lovable reflects the goal of making software creation enjoyable. Growth followed: Lovable reports $10 million in annual recurring revenue two months after launch.
Building through conversation
You describe what you want in your own language, and the AI writes the code. Lovable calls this conversational development.
Chat mode goes beyond generation: the assistant supports you through every phase of the project. You can ask it to explain a concept, try out a variation or fix a bug, all without leaving the interface.
The technical architecture
Lovable generates React and TypeScript for the front end. Supabase provides authentication, the PostgreSQL database and file storage. GitHub stores the code with automatic repository sync, and Netlify hosts the app with one-click deployment.
The team highlights the AI's ability to fix its own mistakes: when a generation fails, the assistant reads the error message and suggests a fix.
Getting to know Lovable: the platform and what it can do
Lovable dev fundamentals
You work in a full development environment that runs in your browser, with nothing to install. The interface brings together AI-assisted code generation, real-time collaboration (in beta) and project sharing.
The core features: generating a complete app from a prompt, code suggestions, error detection, debugging help and documentation generation. You deploy to the cloud in a few clicks and connect a database without any manual setup.
What you can build
With Lovable, you can build:
- product launch pages and company websites
- online stores and service pages
- conference websites with ticketing
- job boards and portfolios
- fundraising platforms and media kits
Lovable also handles heavier applications: subscription platforms, rental marketplaces with search, online auction systems, and mentorship networks with automatic matching.
The tech stack (React, Vite, Supabase)
On the front end, React builds the components and Vite compiles the project, which gives you fast reloads during development.
On the back end, Supabase, an open source alternative to Firebase, provides authentication, the PostgreSQL database, storage and cloud functions. You keep the same database as your data volume or traffic grows.
GitHub stores the code history. Supabase edge functions add the advanced building blocks: calls to an AI model, payments, sending emails.
Getting started with Lovable: building your first app
A few steps are all it takes to go from an idea to a live app.
Creating an account and learning the interface
Go to lovable.dev and create a free account. The dashboard lists your projects. The main interface consists of an input area where you describe your project, plus editing tools to modify the generated elements directly.
You get a version history and an undo function, so you can experiment without breaking your project. If you know how to code, you can sync the project with GitHub and continue in your usual editor.
Writing effective prompts
The quality of your prompt determines the quality of your app. Structure your instructions in four parts: the context (the app's purpose), the task (the features you expect), the guidelines (technologies and visual style) and the constraints (specific limits or requirements).
Write precise descriptions, avoid vague wording, and break complex projects into several successive prompts. An example or a visual reference improves the result.
Connecting Supabase for your database
Supabase adds back-end functionality to your app. To set up the connection:
- Click the Supabase button in the top right corner
- Create a Supabase account if you don't have one
- Authorize Lovable to access that account
- Create an organization, then a project in Supabase
- Go back to Lovable and select the project you created
Connect Supabase before requesting any feature that needs a database. Without an established connection, Lovable sometimes generates incomplete code.
Testing and deploying your app
Test every feature on several devices before publishing, especially authentication and payments, which depend on the connection to Supabase and Stripe.
To deploy, click "Publish" in the top right corner. Lovable generates a public URL you can share with anyone. The "Preview" feature gives you a temporary link to gather feedback without touching the published version.
You can add a custom domain through Entri, Netlify, Vercel or Namecheap.
Lovable's advanced features for no-code
User authentication
You describe authentication in a single sentence and Lovable generates it through Supabase: sign-up and login forms, OAuth login with Google or GitHub, and email verification. Lovable also writes the validation logic and error handling, so you don't have to configure authentication APIs or validation code.
Payment integration with Stripe
Lovable integrates Stripe so you can collect one-time payments or subscriptions directly in your app. The simplest method uses Stripe payment links, which cover a complete checkout flow.
For webhooks and subscription management, Lovable recommends combining Supabase and Stripe. You then process payments server-side and assign roles based on subscription tier.
Building installable mobile apps
Lovable produces web apps, but a single instruction is enough to convert your project into a Progressive Web App (PWA). Users can then install the app on their phone from the browser, open it from their home screen, and access previously loaded pages even offline.
Connecting GitHub for customization
You sync the code to your GitHub repository for collaboration and version control. Sync works both ways: a change pushed to GitHub shows up in Lovable, and vice versa.
This lets you edit the code in your usual environment while keeping Lovable's AI assistance on the same project.
Lovable vs Bolt: which one to choose
Lovable and Bolt take two different approaches to AI-assisted no-code development. For a full overview, see our comparison of vibe coding tools (Cursor, Lovable, Bolt) and our dedicated review of Bolt.new. For other AI tools in a startup stack (CRM, agents, analytics), see our selection of AI tools for startups.
Comparing the user interfaces
Lovable offers a "Select and Edit" feature: you click an element on the page and describe the change you want. Bolt embeds a full development environment in the browser, powered by WebContainers, which suits rapid prototyping.
Technical differences and performance
Lovable stands out with its GitHub and Supabase integrations, which simplify databases and authentication. Bolt doesn't offer these, but its "diff" feature sends only the modified lines to the model, which saves tokens during iterations.
Pricing and value for money
The two vendors bill differently. According to its pricing page, Bolt counts in tokens: the Pro plan gives you 10 million tokens per month for $25, and unused tokens roll over to the following month. According to its own, Lovable counts in credits: the free plan grants 5 credits per day, capped at 30 per month, and the $25/month Pro plan includes 100 credits, with each message using one or more credits depending on the complexity of the request.
With Bolt, you get more back-and-forth for the same price. Lovable's pricing becomes a constraint on a complex project that needs many iterations. Its integrations make up for that if you need a database and authentication from day one.
FAQ
Do you need to know how to code to use Lovable?
No. You describe the app in plain language and Lovable generates the React, TypeScript and Supabase code. Some technical background helps you write more precise prompts and review the code, but it isn't a prerequisite.
Is Lovable free?
The free plan grants 5 credits per day, capped at 30 per month, according to Lovable's pricing page. The Pro plan costs $25 per month for 100 credits. A simple message uses one credit, while a complex request uses several.
Can you export the code Lovable generates?
Yes. You connect your GitHub account and Lovable pushes the code to a repository you control. Sync works both ways, so you can edit the code in your editor and then pick up again with the AI.
Can Lovable build a mobile app?
Lovable generates web apps. A single instruction converts the project into a Progressive Web App, which can be installed on a phone from the browser. For a native app distributed through the app stores, you'll need a different tool.
What should you do when Lovable throws an error?
Chat mode reads the error message and suggests a fix. If the problem involves the database, first check that you've actually connected Supabase to the project: without a connection, Lovable sometimes generates incomplete code. The version history lets you roll back to the previous state.
