Everything in one window
A complete cockpit for coding agents.
Chat, diffs, files, and terminals — the whole loop, without stitching together five different tools.
Run agents in parallel
Spin up as many agents as you like across isolated workspaces and let them work at the same time — no tab juggling.
Built-in chat
Streaming, multi-turn conversations with every agent in one consistent interface — prompts, reasoning, and results.
Diff review
See exactly what each agent changed and review every diff before it lands. Nothing is committed without you.
File explorer + editor
Browse the tree and edit files inline with a full Monaco editor — read, tweak, and ship without leaving Grex.
Integrated terminals
Real terminals attached to each workspace, so you can run, test, and debug right alongside your agents.
Local-first & private
Your workspaces, sessions, and messages live in a local SQLite database on your machine. Nothing leaves unless you send it.
Context, under control
Give every agent exactly the right context.
Great output starts with great context. Grex scopes it per workspace and keeps it local — so every agent works with the full picture of one project, and nothing more.
- Each workspace keeps its own history, files, and sessions — context never bleeds between projects.
- Bring diffs, files, and terminal output into the conversation so the agent sees what you see.
- Switch models or agents mid-task without losing your place.
