Lovable

Lovable Summary

Lovable is a popular cloud-based full-stack application builder. Like Lovable, Denjin lets you build full-stack applications, including support for Supabase integration.

Key Differences

• Denjin runs locally; Lovable runs in the cloud – This is the core distinction. Denjin runs apps directly on your machine, which means your code stays local and you can easily switch between Denjin and tools like Cursor or VS Code. However, on older machines, Lovable’s cloud-based approach may offer a better experience.

• Lovable’s free tier is more restricted – Lovable’s pricing restricts free users to 5 messages per day and public-only projects. Denjin, on the other hand, is bring-your-own-API-key. You can use generous free APIs like Google’s Gemini, which currently offers up to 500 messages/day for Gemini 2.5 Flash. Denjin apps are also private by default.

• Denjin gives you full control over AI models – Denjin lets you choose from leading or low-cost models across providers. Lovable doesn’t publicly specify which models it uses, which can lead to confusion if the behavior changes unexpectedly. With Denjin, you’re always in control.

Which Should You Choose?

If you prefer a local app builder with greater control, flexibility, and a generous free tier, Denjin is a great choice.

If you’d rather not run apps locally—especially if your computer can’t run Node.js—then Lovable’s cloud-based approach might be a better fit.
