Lovable you can actually host yourself

What it does

Tinykit is an open-source platform where you prompt an AI to build web apps, and it handles code, database, content, and deployment. Each app is a single Svelte file you can edit directly, backed by auto-generated PocketBase tables that sync in real-time. You build at /tinykit/studio and the finished app serves from / — or from its own domain, since one server can host hundreds of apps with domain-based routing.

The interesting bit

The “batteries included” part is the real story: realtime database, file uploads, a mini-CMS for editing text without touching code, a visual design system editor, and time-travel snapshots on every change. It’s less a code generator and more a small self-hosted PaaS with an AI attached.

Key highlights

• Agentic builder that writes code, creates tables and fields, and wires them together
• Runs on your own server via PocketBase; Docker optional, Railway one-click deploy available
• Time Travel: snapshot on every change, undo anything
• Bring your own LLM — OpenAI, Anthropic, or Gemini
• 12+ starter templates (Kanban, invoice generator, HN reader, Linktree, etc.)

Caveats

• Explicitly early alpha — the README says so itself, and it’s “evolving every day”
• Several headline features are still “soon”: auth, background jobs/CRON, server-side routes, community showcase
• One Svelte file per app is tidy, but the README doesn’t say how that scales for anything non-trivial

Verdict

Worth a look if you want the Lovable/v0 experience without renting your soul to a hosted platform. Skip it if you need auth or a backend today — those are still on the roadmap.
