OpenChamber is a lightweight, agentic development environment that lets developers harness AI models without leaving their workflow. It runs on macOS, Windows, and Linux, and offers a native desktop app, a mobile beta, and browser/PWA access that can be gated with a UI password. The core features include Session Goals, which keep the agent pursuing a target even if the app is closed, and Multi‑run / Fusion Run that lets you run a single task across five models, keeping the best result or fusing the strongest parts.

The interface is tightly integrated into the editor: you can open files directly from tool output, right‑click on selections for context actions, and manage parallel runs with the Agent Manager. Project actions let you launch dev servers, SSH tunnels, and local URLs, while a scheduled work feature allows cron‑style prompts that can be paired with Session Goals. Privacy is built in—no project data is collected, browser access can be password‑protected, and a Private Relay tunnel gives end‑to‑end encryption without opening ports.

OpenChamber is open source on GitHub, runs on the Open Code SDK, and is free to use. Install it with curl: `curl -fsSL https://opencode.ai/install | bash`. It’s already praised by users like Srikanth for its polish and streaming capability.
