Quests

Quests is an open-source desktop application for building and running full-stack applications on a user's computer with an LLM provider. It supports bring-your-own-key connections to numerous providers, including OpenAI, Anthropic, Google, OpenRouter, Mistral, Groq, xAI, DeepSeek, and Ollama.

The documented workflow includes creating multiple applications, making targeted edits with a coding agent and real-time linting, versioning and restoring projects, comparing model and application outputs with evaluations, and exporting applications that can run anywhere. It includes templates for React, Angular, Astro, and Svelte, and runs on macOS, Windows, and Linux.
