What is DevChain?
DevChain coordinates Claude Code, Codex, OpenCode, Antigravity and GitHub Copilot as teams of coding agents. Each agent runs in a separate tmux session, while a shared board tracks epics and subtasks. Its development template separates planning, implementation and code review, with plans submitted for approval before implementation.
The application serves a browser interface and stores its state in a local SQLite database. Projects can also run on user-managed virtual machines, with encrypted connections and bidirectional file synchronization through Syncthing. Optional mobile apps provide chat, task reassignment, terminal viewing and notifications, while review and merging remain on the web.
DevChain is free and source-available under the Elastic License 2.0. Its stated restrictions prohibit providing it as a managed service or a competing commercial offering. Agents use the user's own provider accounts rather than an included model service.

Key capabilities
- Agent coordination Organizes planning, implementation and review teams, with provider and model selection per agent.
- Live terminals Streams individual tmux sessions to the browser, with scrollback and manual takeover.
- Shared work board Lets agents claim epics and update task status through DevChain's MCP tools.
- Code review Provides a live pre-commit diff with inline comments, mentions and discussion threads.
- Remote execution Runs projects on user-managed virtual machines and synchronizes project files through Syncthing.
- Workflow tracking Imports ClickUp and Jira tasks, synchronizes statuses and subtasks, and records session transcripts, token usage and costs.
Where DevChain fits
DevChain fits development workflows where several coding agents need to share a plan, divide implementation work and submit changes for review. It can also keep a project running on a dedicated virtual machine while the developer's laptop is asleep, with mobile access for questions and progress monitoring.
Before deployment, teams should check Node.js, tmux and provider CLI requirements, provider account access and expected model costs. Remote execution additionally requires Syncthing and a suitable virtual machine. Teams should review file synchronization behavior, provider data handling and the license restrictions before using it with sensitive projects or offering services around it.
