StateSync is an alternative to Headroom
StateSync vs Headroom
Headroom compresses tool output in a proxy you run beside the agent. StateSync removes only output that adds nothing, and the agent finishes in fewer, shorter requests.

Where StateSync wins
Smaller requests, not a bigger bill.
Compressing a request can break the provider's cache, so more of each turn is billed at full price. In Dasein's July test of 100 tasks, Headroom cost 44% more than plain Claude Code.
Savings everywhere, not in one place.
Headroom saves mostly on what the agent reads. StateSync saves on shell output and on finding code, and the agent finishes in fewer, shorter requests.
Nothing to run beside the agent.
Headroom needs its proxy running, or a wrap command for each agent. StateSync is one app.
Side by side
Pick Headroom if you want a free, open source compressor you can also call as a library, or use an agent StateSync does not run.

Headroom's figures are its own and its testers', as published. StateSync's come from our own run on one model, so the two were not measured the same way.
