Quests is a privacy-first, open-source desktop app that lets you build and run full-stack AI-powered applications entirely on your local machine. No cloud dependencies or sign-ups required. Bring your own API key for any LLM (including Groq for blazing-fast inference), experiment with multiple projects simultaneously, and export polished apps with one click, all powered by a smart coding agent that handles edits, linting, and error fixes in real-time.
Why did we build Quests?
We believe developers prefer their tools to be open source and local. We built Quests as the alternative to the cloud-hosted non-private vibe coding tools like v0, Lovable, and Bolt.
What makes Quests unique?
What sets Quests apart is its zero-friction local runtime with no terminals, no Docker, just download and build. You can juggle 5+ full-stack apps at once (each with its own AI agent), switch LLMs mid-project. Unlike cloud-heavy alternatives, it’s 100% OSS (Apache 2.0), with built-in versioning to rollback experiments safely.
Bonus: v1.4 just added any JS framework (Next.js, Svelte, Vue, and even HTMX).
