cornercase
The fastest way to run agents in parallel
A fast terminal multiplexer for coding agents. Turn GitHub, GitLab, Linear, Jira, Plane or Shortcut issues into running Claude Code, Codex or Gemini agents in a click. Each agent gets its own git worktree and tab. See which agent needs you, review the diff as it's written, and close the window: they keep running Away from your desk? Continue from your phone or on Telegram. Everything works with clicks. Really fast: 34 ms launch, 53 MB RAM. Free and open source. Linux and macOS.
Hey!,
I'm Zam.
I used to wake up and check if my dog memecoin had made me rich. Now I check what the 10 agents I left running overnight did 💀
Starting ten agents is easy. Keeping up with them isn't. So I built cornercase, the fastest way to run agents in parallel.
Each agent gets its own branch, worktree and tab.
See who's working, who needs you and who's done at a glance.
Read the diff while it's being written.
Close the laptop. Nothing stops.
Opens in 34 ms and uses 53 MB of RAM. Open source.
Last week I shipped 40 PRs in 24 hours with 51 agents. Not a typo.
Brutal feedback welcome 🙏
