A local-first Chrome extension for tabs, tasks, notes, workspaces and wishlists. Your data stays in a file on your computer — no account, no cloud sync.
Building software well means measuring it constantly — and living in the tools we ship. Over the years we assembled our own checks for speed, accessibility, security and how a page reads to a machine, and we built a Chrome extension when tab managers all wanted a cloud account we did not.
Publishing them costs us very little and is the most honest sales pitch we know: use the instrument, see how we think, and decide for yourself whether you want us building the thing it measures.
We publish an instrument whenever one proves itself on client work. If there is something you keep wishing existed, tell us — that is usually how these start.
