Sterna
A multi-model AI workspace, now open source under AGPL-3.0: side-by-side model chat, a sandboxed coding agent with a GitHub issue-to-PR flow, a RAG knowledge base, MCP connectors, voice rooms, and per-message cost accounting.
- Open-sourced under AGPL-3.0: the full Django/DRF backend, React 19 + TypeScript frontend, FastAPI microservices, and the Kubernetes/Terraform infrastructure
- Sandboxed coding agent that turns a GitHub issue into a reviewed implementation plan and a pull request, with an in-browser Monaco IDE over its workspace
- Every message carries measured tokens, cost, and latency — pgvector RAG, MCP connectors, live multi-agent voice rooms, and BYOK provider keys round out the workspace
