Keep your laptop fast while your agents build
Headroom runs your coding agents' builds and tests on other computers or cloud sandboxes, so a few agents at once can't max out your laptop.
Every agent you start builds on this Mac.
Builds run where there's room
Your agents send their builds and tests to Headroom, and it runs them on another computer or sandbox with room. Uncommitted changes go too, with no commit or push. Each branch keeps its own checkout there, so node_modules and target carry over to the next run.
$ headroom run --os macos -- xcodebuild test headroom: syncing 4c1e09d27a plus uncommitted changes to mac-mini headroom: job 7f3a20c9 running on mac-mini ** TEST SUCCEEDED **
Connect each agent with one switch.

Jobs wait their turn
Each machine takes a few jobs at a time. The rest wait in line, and each agent is told its place.
Add a computer from a list
Pick one of your Tailscale devices, nearby computers or SSH hosts. If it needs a password, Headroom asks once and forgets it.
8 cores and 32 GB would save about 7 agent hours a week.
No spare computer needed
Paste an E2B or Daytona key, and Linux jobs run in sandboxes on your account. Idle ones pause after 10 minutes.
Bigger sandboxes when builds need them
When a pool's builds spend most of their time at full CPU, Headroom says how many agent hours a week the next size up would save. One click resizes it.
Safe to hand to your agents
Your .env files, keys and credentials never leave your laptop, even ones you've committed. Agents can run jobs but can't add machines, change settings or raise a limit.
Nothing is installed on your computers. Headroom adds one line to ~/.ssh/authorized_keys, and only when you add a computer with a password.
