Lovable vs Bolt vs v0 vs Replit vs Cursor: where each gets stuck
A plain comparison of Lovable, Bolt, v0, Replit and Cursor: what each one is good at, where projects built with each tend to get stuck, and how to choose.

Lovable, Bolt and v0 are browser-based builders where you describe an app in a chat and get working code, Replit is a cloud workspace with an AI agent that can build and host the whole thing, and Cursor is a code editor with AI built in that runs on your own computer. The first three are quickest for getting from idea to something clickable. Replit and Cursor give you more control and ask more of you in return. All five tend to get stuck in the same places: permissions, payments, production setup and projects that have grown past what the AI can keep in mind.
This comparison covers what each tool is like to work with. It leaves out pricing, which changes often, so check each vendor's site for current plans.
What is each tool, in one paragraph?
Lovable is a chat-based app builder that runs in your browser. It generates a React front end and connects to a backend for you, either Lovable Cloud (a managed backend built on Supabase) or a Supabase project of your own. It can sync your code with GitHub and publish the app on a Lovable address or on your own domain.
Bolt (bolt.new, from StackBlitz) is also a chat-based builder in the browser. It runs a full development environment inside the browser tab, so you see the files and the running app side by side. It can host the app, and it offers its own database or a connection to Supabase.
v0 is Vercel's builder. It is especially strong at user interfaces and defaults to Next.js. It adds databases and other services through the Vercel Marketplace (Supabase and Neon, for example) and deploys to Vercel.
Replit is a development environment in the cloud. Its Agent can plan and build an app, and Replit itself provides the database, secrets storage and deployment. It works with many languages, including Python.
Cursor is a desktop code editor, based on VS Code, with an AI agent that can read and change your whole project. It doesn't host anything. You choose the stack, the database and where the app runs.
How do they compare side by side?
| Tool | Where you work | Strongest at | Where projects tend to get stuck | Suits |
|---|---|---|---|---|
| Lovable | Browser chat | Full apps with login and a database, fast | Supabase permissions (RLS), auth redirects on a custom domain, long prompt loops | Founders and small teams without a developer |
| Bolt | Browser chat with visible files | Quick prototypes in JavaScript stacks, seeing the code as it's written | Large projects where fixes loop, database and deployment settings | People who want to watch and tweak the code |
| v0 | Browser chat | Polished interfaces and Next.js apps on Vercel | Server and client code mix-ups, environment variables, backend logic beyond the UI | Designers and teams already on Vercel |
| Replit | Cloud workspace with Agent | Apps in many languages with hosting and database in one place | Mixing development and production data, costs of long Agent sessions, moving off the platform | People who want everything in one account |
| Cursor | Desktop editor | Real codebases of any size and any stack | Everything outside the code: hosting, secrets, security setup | Developers, or people willing to learn the basics |
The table describes common patterns. A careful person can ship a solid app with any of these, and a rushed project can get stuck in any of them.
What is each one good at?
Lovable
Lovable is good at getting a complete app, with accounts, a database and a decent design, in front of people quickly. The GitHub sync matters: it means the code isn't trapped, and a developer can review or work on it with normal tools.
Bolt
Bolt shows you the files as they change, which helps if you want to learn what the AI is doing. It runs the app inside the browser, so there is nothing to install. It is a good fit for front-end heavy projects and quick experiments.
v0
v0 produces some of the cleanest interface code of the group, and its default stack (Next.js on Vercel) is a well-trodden path for production apps. If your project is mostly screens and forms, it gets you far.
Replit
Replit's strength is having everything in one place: code, database, secrets and deployment. It also handles back-end languages that the browser builders don't focus on, which helps for scripts, bots and APIs.
Cursor
Cursor works on real repositories of any size. You can open a project exported from Lovable, Bolt or v0 and keep going with full control. It suits people who are ready to understand their code, or who work with a developer.
Where does each one tend to get stuck?
Some problems show up across all five. These are the ones we see most often:
- Permissions. The app works, but users can read each other's data. In Supabase apps this almost always comes down to Row Level Security.
- Payments. Stripe checkout works, but access isn't granted afterwards, usually because of webhooks or test and live keys. See why a customer pays and still has no access.
- Production setup. Domains, environment variables and auth redirect URLs. Our guide to putting a Lovable or Bolt app on your own domain covers the usual traps.
- Size. Past a certain point the AI stops seeing the whole project. Fixes start contradicting earlier changes, and each prompt breaks something else.
A few patterns are more specific:
- Lovable: moving between Lovable Cloud and your own Supabase project isn't a one-click step, so choose deliberately early on.
- Bolt: existing projects can't be switched from Supabase to Bolt's own database, and connecting a new database to a project that has one can replace the connection. Read Bolt's notes before you change it.
- v0: Next.js separates code that runs on the server from code that runs in the browser. When that line is drawn wrong, you get errors that are hard to read, or secrets that end up public.
- Replit: the development and production databases need to stay separate, and long Agent sessions can use a lot of credits while the Agent retries the same fix.
- Cursor: the editor will happily change dozens of files at once. Without version control habits (small commits, reading the diff), it's easy to lose track of what changed.
How do you choose?
Ask yourself three questions.
- Do you want to see and own the code from day one? Bolt, Cursor, or Lovable with GitHub sync turned on.
- Do you need a back end in a language other than JavaScript? Replit or Cursor.
- Is the product mostly interface, and do you already use Vercel? v0.
If none of that applies and you want a working app with login and a database this week, Lovable or Bolt are the shortest path.
Can you switch tools later?
Usually yes, through GitHub. A common path is to start in Lovable, Bolt or v0, push the code to a repository, and continue in Cursor once the project grows. What moves less easily is the backend. If your data lives in a builder's managed database, check how to export it or claim it before you depend on it.
Quick answers
Which one makes the most secure apps? None of them is secure by default for your specific data. Each can produce a safe app, and each can leave a table open. Use our security checklist whichever you pick.
Is one of them best for non-developers? Lovable and Bolt ask the least of you at the start. Cursor asks the most.
Can a developer help with any of them? Yes. They all produce standard code, mostly React or Next.js with a common database behind it.
Stuck with one of them?
