Hyfn
A better way to track
and bill for AI work.
Every session your coding agents run becomes a billable work item — with evidence, invoices, and webhooks. Without a keylogger.

From the makers of Worklog
Built in the open, on Worklog
Hyfn is powered by Worklog, our source-available (fair-code) desktop work logger and capture agent. Read every line of what runs on your machine, ship your own connector under any license, or skip the cloud entirely and report to your own webhook.
