Arclat is a studio shipping focused developer tools for teams building AI agents. Our tools live where engineers already work: inside the editor and the command line.
🟢 Relay (live)
Find the latency in your AI agent, before your users do.
An open-source MCP server + CLI that audits AI agent and voice-agent codebases for latency bottlenecks. It reads your real source with an AST engine, ranks issues by the time they cost, runs a verification pass to drop false positives, and can apply fixes directly from Claude Code.
No account. No API key. No backend. It runs entirely on your machine.

We ship deliberately, one focused tool at a time. The next products for teams running AI agents in production are in design. Details soon.
Built for the terminal. Our tools plug into the editor and the shell, not another browser tab.
Your code stays yours. Analysis runs locally wherever possible. We sync metadata, never your source.
One focused tool at a time. We'd rather ship one product that nails a real problem than ten that almost do.
Relay is open source and we read every issue. Start with CONTRIBUTING.md, or open a discussion if you've found agent latency our detectors miss. Those reports are the single most useful thing you can send us.
Security reports go to the process in SECURITY.md, not to a public issue.
