Tool insights
Reason lets engineers run several coding agents on one shared network instead of juggling separate tools. Sessions carry across the app, the CLI and the API, and work can run on a local machine or a Reason cloud computer.
Engineers who use more than one coding agent end up with separate sessions, separate setups and no shared place to start or follow work. Reason puts those agents on one network and keeps sessions in sync across its surfaces.
Engineers who already use tools such as Claude Code, Codex or Cursor and want them to work together, or who want to hand tasks off from Slack or GitHub. Anyone who needs a clear price before trying a tool should know that pricing isn't stated in the facts we have.
