Bill every hour you work in Linear.
A timer that lives inside the issue, rates and budgets on every project, and timesheets your clients can read. No new tab, no context switch.
14-day free trial · No credit card · Reads your issues, posts time as comments.
Everything time tracking should be, and nothing it shouldn't
Klockwurk reads one thing from Linear — the issue you're on — and does the rest server-side. A Linear redesign can never mis-bill a client.
In the issue
The timer sits in Linear's sidebar, styled like the rest of it — total, your time, the estimate — without ever leaving the page.
Rates & budgets
Set a rate on a Linear project and the hours you sold. Klockwurk snapshots the rate per entry and warns you at 80% of budget.
Timesheets & export
Roll time up by member, project, or day. Filter, review, and export a clean CSV your client can read. Ask Claude, if you use MCP.
Start a timer right from the list.
A control sits beside every issue in Linear. One click runs a live timer; one more stops it. Switch issues and the old timer closes itself — you can never bill two clients for the same hour.
