What Clockoli is
Clockoli is a free, open-source time tracker delivered as a Chrome or Chromium extension, with GitHub providing sign-in and storage. It treats GitHub issues, pull requests, and any website URL as tasks. A timer is available in the GitHub header and, on other sites, in a browser-toolbar popup. One timer per account stays synchronized between browsers. For reviewing work, Clockoli offers an editable timeline, daily, weekly, and monthly calendar views, plus search by URL or title. Reports can organize shared-repository time by day, person, source, or task, then export to CSV, JSON, or PDF. The browser can also generate invoices, while hourly rates remain in the browser. Records are saved as plain JSONL files in a GitHub repository and can be read from a clone. The extension communicates directly with GitHub; the site says Clockoli endpoints do not receive tracked URLs, titles, or descriptions. Read access to a shared repository exposes those details and timestamps, but rates remain local. Setup uses GitHub device flow and a private repository. Clockoli is an open beta installed as an unpacked extension, with updates applied through git pull.

Clockoli suits people who already use GitHub and want task-based time capture for issues, pull requests, or web work. It also fits teams needing shared-repository reports, browser invoices, and locally retained hourly rates.
