Lovable vs Bolt vs v0: choose the app you can maintain
Compare repository import, code handoff, publishing, and generation costs before choosing an app builder.
Choose an app builder by the work you need to bring in and the code you need to take out. A convincing first screen is a useful start. For a project you intend to maintain, the next questions are whether it can use your repository, how changes reach production, and what happens to the database when you leave.
Our starting shortlist is Lovable for a new app with a managed backend, Bolt for a JavaScript project you want to edit in the browser, and v0 for a GitHub-and-Vercel workflow. These are fits suggested by the documentation, not rankings of generated-code quality.
Start with the repository you already have
| Builder | Starting from existing code | Review before release |
|---|---|---|
| Lovable | Git sync creates a new repository; existing repositories cannot be imported | Synced commits update the preview; publishing is a separate action |
| Bolt | Import an existing GitHub repository within its supported JavaScript stack | Work across branches; merge branches in GitHub |
| v0 | Import a GitHub repository and choose a base branch | Generated changes go to a working branch; publishing can merge a pull request |
Lovable’s Git sync supports GitHub, GitLab, and Bitbucket. Once connected, code can move both ways on the synced branch. The initial connection still starts from Lovable and creates a new repository. Its export includes database migration files, not the database contents. A team migrating an established application should resolve that import constraint before investing in a prototype.
Bolt’s GitHub integration supports import, automatic commits, and branches, but merging happens in GitHub. Its documentation also warns that near-simultaneous Bolt and GitHub changes can result in Bolt overwriting the GitHub version. For a handoff between a builder and a developer, agree who edits the branch and test that transition.
v0’s GitHub workflow creates a working branch from the selected base and pushes generated changes there. Its publish action can create or reuse a pull request, merge it into the base branch, and wait for deployment. Branch protection still applies. If every production change needs a human review, set that requirement in GitHub and verify it with a small change.
Check the stack before you compare the output
Bolt supports JavaScript backends, including Node.js; it does not support Python or PHP backends. It also documents an Expo route for mobile apps. Browser choice affects the working environment: Safari’s Code view is read-only, and its previews are hosted. A successful Chrome trial therefore does not establish the same editing experience for a teammate using Safari.
Lovable documents full-stack app creation with managed database and authentication capabilities. Test the backend as part of the prototype: create two accounts, write a record as one, and check what the other can read. For v0, inspect the connected Vercel project and the services the generated app uses. The builder’s preview is only one part of the deployed system.
Credits and tokens buy different amounts of work
| Builder | Generation budget | What to measure |
|---|---|---|
| Lovable | Workspace credits and usage-specific grants; paid plans add general credits | Building, Cloud, and in-app AI consumption after included grants |
| Bolt | Pro starts at $25/month with 10M tokens; Teams starts at $30/member/month | Context cost as the project grows; per-member token use |
| v0 | Free allowance and paid per-user plans with usage credits | Chosen model, generated changes, and connected service bills |
Sources: Lovable pricing, Bolt pricing, and v0 pricing. Plan names, promotions, and allowances change. Compare the price shown for your billing interval and team size rather than treating the entry price as the cost of operating an app.
Lovable’s usage documentation distinguishes build usage, Cloud usage, and AI features in deployed apps. General credits can cover these after the relevant grants are exhausted. Bolt says project filesystem synchronization accounts for much of its token use, so a longer project can cost more to revise. Teams allowances are allocated per member rather than pooled. Track the second and third change, not just the first prompt.
Run a handoff trial before committing to a builder
Give each candidate the same small app: a private request tracker with two users, a status field, and a CSV export. Use synthetic records. Keep the acceptance criteria fixed and record every repair you make.
- Build and inspect: sign in as both users, test record visibility, submit invalid input, and open the exported CSV.
- Make a second change: add a due date and filter. Record generation spend and review time for this revision separately.
- Hand over the code: clone the repository in a fresh environment and build it from the documented setup. Identify required secrets and services.
- Publish and recover: verify the live URL, then restore the previous release. Check whether the data needs a separate recovery step.
Score the result with our coding-agent trial scorecard. A builder earns its place when the maintained app, review effort, and operating costs fit your team. Save the repository and data-export instructions alongside that decision.
