What it does
Coder lets companies give developers ready-to-use coding environments on their own cloud or servers, instead of everyone setting up their own laptop. Environments are defined as templates and shut down automatically when idle to save money.
It can also hand coding tasks to AI agents that run on the company's own infrastructure, using any AI model. AI keys stay out of the workspaces, every action is tied to a real user, and admins get central controls for model access, cost tracking and audit logs. Agents like Claude Code, Codex and OpenCode can also run inside isolated Coder workspaces.
There is a free open-source version and a paid Premium tier for large teams.
Who it's for
Engineering and IT teams managing development environments and AI coding agents for many people.
