Forge inside MDx

Give agents real work.
Keep the final say.

Tell Forge what done looks like. MDx gives the work an isolated branch, shows you the proof, and stops where your judgment begins. Start on Mac, then check in from the web or iPhone.

Start with the outcome.

Describe the job once. Forge plans and runs it on an isolated branch, then returns the work for review.

See what happened before it ships.

Review the diff, the checks, and the proof in one place. Ask for a revision or decide what moves forward.

Mac at the center. Everywhere else when it matters.

Use the flagship Mac app for the full experience. Check in from the web or iPhone without losing the thread.

Hosted beta

Small by design.

MDx is early. Expect rough edges and direct conversations with the people building it. We are inviting a small group before making bigger claims.
