Clockoli vs Harvest

Harvest is the closest thing to a direct competitor on the list. It claims 70,000+ companies, and it is really an invoicing product with a timer attached rather than a tracker that later learned to bill. If getting money out of clients is the whole job, it has years of head start on the paperwork around it.

What Harvest does better

Invoicing maturity. Clockoli now invoices from a filtered report — numbered, taxed, printed or saved as PDF — but that is where it stops. Harvest adds the paperwork around getting paid: recurring invoices, reminders, payment integrations and expenses. If chasing money is the main job, Harvest is the more complete product.

The GitHub integration is the best of the set. A “Track time” button on every issue and pull request header, and — the good part — the popup tells you ”Write copy outline has 1:45 tracked to it” before you start. It remembers the project per repository and the task per issue for the whole team, and the entry links back to the issue. That per-task context is the cheapest useful thing any of these extensions do, and we intend to copy it.

Duration-first, deliberately. The default day view is a timesheet: project, task, hours. Start and stop times are hidden behind an account-wide setting. Plenty of teams genuinely never want to think about intervals, and Harvest is honest about building for them. Day tabs across the week carry per-day totals and act as the navigator for the whole timesheet.

Two rows are worth expanding.

Rate privacy. Harvest stores rates in its service with role-controlled access; that does not mean every teammate sees them. Clockoli keeps rates out of shared time files. Access to the browser and financial exports still needs protection.

Getting your data out. Harvest provides report exports and an API. Clockoli’s canonical records are already files in Git that you can clone. Its commit history is inspectable, but is not an immutable audit log. Harvest also offers an activity log on Enterprise; see the sourced comparison.

Harvest’s current pricing includes a Free plan for one seat and two projects, with invoicing and expenses. Team plans and some usage are paid. Check those limits against your actual billing workflow.

Which to pick

Take Harvest if the billing paperwork is the job — retainers, reminders and payment links. That is not a hedge; it is the answer. Also take it if your team wants duration-only timesheets and never wants to see a start time.

Take Clockoli if you want precise intervals per URL, or if you would rather your rates and your clients’ task titles were not in a separate tracker’s database. You can invoice from those hours while the time records stay in your GitHub repository.
