ACE Sidecar
A local proxy that sits in front of your coding agent and
A local proxy that sits in front of your coding agent and tells you what each session actually cost, where the time went, and which optimisations would be worth anything on your traffic. Runs on your machine, uploads nothing. Beta opening now.
Hey everyone! :wave:
We just published a detailed post on what we’ve been building: The Local ACE Sidecar!
:book: Read the full announcement: https://acefleet.dev/blog/announ...
Why we built this:
Modern AI coding agents (Claude Code, Cursor, multi-turn terminal scripts) make development super fast, but how it's calculating tokens in/out and how cache reads works under the hood remains a blackbox with little control by users.
The ACE Sidecar **runs locally on your machine** to observe your coding sessions, spot context inefficiencies, and give you full visibility into what’s happening behind the scenes—before token bills explode.
ACE Sidecar will be published as an open source project, fully community owned and Upcoming Early Access:
We are getting ready to roll out distribution via Homebrew, npx, and MCP. If you want to be among the first to get early access and optimize your local AI development workflow, sign up today!
