💡 Our Take
Choose bolt.diy if your team is technical and wants to inspect, fork, and adapt the AI app builder itself. Choose Lovable if you want a more productized hosted workflow for building apps quickly with less infrastructure responsibility.
bolt.diy - Pros & Cons
Pros
- ✓Public GitHub template with strong community signal: 19.5k stars and 10.4k forks were visible on the repository page in the 2026-06-15 capture.
- ✓Forked from stackblitz/bolt.new, so it targets the same prompt-run-edit-deploy workflow rather than a generic chatbot coding interface.
- ✓Designed around user-selected LLMs, which gives technical teams more flexibility than app builders tied to a single model provider.
- ✓The repository is public, so developers can inspect the code, fork it, and adapt the implementation to their own infrastructure.
- ✓The project shows active development signals with 77 issues and 39 pull requests visible on the GitHub page in the 2026-06-15 capture.
- ✓Best suited for developers who want more control over their AI app builder stack than hosted-only products usually allow.
Cons
- ✗No hosted product or managed onboarding is visible in the provided website content, so users should expect a developer-led setup process.
- ✗The GitHub page shows 77 issues and 39 pull requests, which can mean users may encounter unresolved bugs or fast-moving changes.
- ✗Pricing for model usage, hosting, and deployment is not published on the repository page, so total cost depends on the user’s own setup.
- ✗Non-technical users may find it harder to use than hosted AI app builders because the primary website is a GitHub repository.
- ✗Commercial support, enterprise SLAs, and managed security documentation are not visible in the provided website content.
Lovable - Pros & Cons
Pros
- ✓Real React + Supabase output — not a locked-in low-code black box
- ✓Integrated Cloud gives you hosting, Postgres, and secrets without extra vendors
- ✓Visual Editor is genuinely useful for non-technical iteration
- ✓GitHub export lets a developer take over cleanly when scope grows
- ✓European GDPR-first data handling matters for EU customers and regulated verticals
Cons
- ✗Credit costs escalate quickly in Agent Mode on larger projects
- ✗Only outputs a React/Supabase stack — no Vue, Svelte, or non-Supabase backends
- ✗No MCP server, so custom tool wiring means writing code inside the project
- ✗Business plan pricing raises credit costs versus Pro for the same edit types
