Relay – open-source coding agent for non-mainstream/Chinese LLM providers

An open-source coding agent called Relay has been released, supporting non-mainstream and Chinese LLM providers like DeepSeek, Qwen, and GLM. The Electron app offers chat and code workspaces with file editing, command execution, and human-in-the-loop permissions, and encrypts API keys locally. It is in early public beta and welcomes community contributions.

An open-source, dark-mode desktop coding agent — built for people who want to use non-mainstream LLM providers , not just the big three. Relay is an Electron app that puts DeepSeek, Qwen, GLM, Kimi, MiniMax, and other open/Chinese models on equal footing with the usual suspects. Bring your own API key or run locally via Ollama , pick a model, and work in either a Chat workspace or a full Code workspace with real file editing, command execution, and human-in-the-loop permissions. Relay is an early public beta think alpha/0.1 . It already does a lot and is usable day to day, but it is not polished production software yet — you should expect bugs, half-finished corners, the occasional crash, and provider quirks rate limits, model-specific errors, auth gotchas across the many supported providers . That's normal for software this young. This is being shared openly precisely so we can fix those things together. If you hit an error, please open an issue https://github.com/LeventeNagy/relay-coding-agent/issues with what you did, which provider/model you used, and the error text or a screenshot — that's the single most helpful thing you can do. Bug reports, fixes, and ideas are all genuinely welcome; with more eyes on it we can squash these issues much faster than I can alone. See CONTRIBUTING.md /LeventeNagy/relay-coding-agent/blob/main/CONTRIBUTING.md . Known in-progress areas: signed installers / auto-update, broader automated test coverage, and additional renderer hardening. Your API keys are not affected by any of this — they're encrypted on your own machine and never leave it see the security model below . 📣 Follow @ for updates, progress, and release notes. levyathan on Twitter/X Many providers, one router. DeepSeek, Alibaba/Qwen DashScope + coding/token plans , Z.AI / GLM, Moonshot / Kimi global + China , MiniMax, SiliconFlow, Tencent, Xiaomi, OpenRouter, and Ollama Cloud — via the Mastra model router. Add a key in Settings and its models appear in the picker. Chat workspace. Streaming replies, reasoning "thinking" controls where the model supports them, image/document attachments, and web search + deep research Tavily / Brave / DuckDuckGo, key optional . Code workspace. Projects live in real folders. The agent reads, writes, and edits files and runs commands scoped to the project , with permission modes Ask / Approve / Full . Plan mode asks clarifying questions and proposes a plan before touching anything. Sources your design docs + framework docs are kept in the agent's context every turn so it never loses the plot, and new projects default to a Next.js + shadcn/ui stack the agent scaffolds and keeps current. Plugins MCP . Connect Model Context Protocol servers — Notion and Linear via one-click OAuth; GitHub, Filesystem, Git, Supabase OAuth , Convex, Postgres, and more. Plugins are chosen per conversation and filtered by workspace. Skills. Reusable instruction packs the agent can pull in on demand. Parallel sessions. Start a run in one session and switch away — it keeps streaming and saving in the background, with a "working" indicator. Context management. Per-model context windows, automatic compaction of older turns, and a live usage meter. - API keys, plugin credentials, OAuth tokens, and search keys are encrypted at rest with Electron safeStorage in the app's userData directory. - Decrypted secrets never leave the main process — the renderer only ever sees key names and connection status. - File and command tools are confined to the active project folder; writes and shell commands are gated by the permission mode path traversal is blocked unless you grant Full access . - The renderer runs with contextIsolation and no Node integration; links open in your real browser, never an in-app window.
