About

OpenCoWork is an open-source software tool for developers who work with code, terminal output, and project files. It provides an agent-based way to work with a local development environment instead of keeping the agent limited to a separate chat context. The tool is intended for tasks where an agent needs to inspect project material and make changes with the developer’s permission.

With Local Agency, agents can read and write files and execute shell commands when the user allows those actions. Its context-awareness functions let agents explore a codebase and review logs without requiring the developer to manually copy each item into a conversation. This can support work such as examining existing code, using terminal information, and applying changes to files. OpenCoWork also supports task orchestration, allowing complex requests such as refactoring a module and updating its tests to be divided among specialized sub-agents.

The user remains involved through a transparent tool-call approval system. This approval process makes file access, file changes, and shell command execution subject to the developer’s permission. As a result, OpenCoWork fits workflows in which the agent assists with development tasks while the human retains control over actions taken in the local environment.

OpenCoWork is available for Windows and is distributed under an open-source license. MirrorNest mirrors the official Windows build directly on its own storage and scans it for malware before publishing it in the catalog.

What's new in v1.4.0

Added - Sign in to a RoutIn desktop account from the sidebar. Tokens stay encrypted in Main (safeStorage); the window only sees the profile, never the access or refresh token. - Phone remote control from the account menu: enable, scan a QR, and pair a phone over SignalR. Remote terminal execution and git commits from the phone are off by default. - Added Claude Fable 5.1, Gemini 3.8 Flash (official thinking_level LOW/MEDIUM/HIGH), Gemini 3.7/3.6 Flash, and Gemini 2.5 Pro/Flash/Flash-Lite to the Routin AI catalog. - Anthropic models now expose a thinking-budget slider on the model switcher (minimum 1024 tokens, default 10K, capped by the model's output limit). Changed - A quoted prompt typed while a run is in flight is injected into that run (agent/append-messages) instead of waiting for a brand-new turn after the current one finishes. - New sessions pick a model in this order: the composer selection, the project binding, a fixed new-session default, then the global active model. - Native Worker outbound HTTP now uses the same OS/system proxy Electron resolved (Clash, Surge, a corporate PAC). Provider traffic no longer bypasses the proxy the renderer already honors. - Channel auto-reply and cron background runs now persist late-disclosed thinking in front of the answer, matching the desktop transcript. Fixed - Fixed Anthropic interleaved thinking signatures overwriting an earlier block. Each signature stays on the thinking block it belongs to, so the next user turn is no longer rejected by the Messages API. - Fixed OpenAI Responses reasoning item ids being dropped from persisted thinking blocks, which broke cross-turn reasoning replay on endpoints that never return encrypted_content. - Fixed Copilot-only local model fields leaking onto other providers when a Copilot row was copied or restored.
