solidtime
Solidtime is open-source time-tracking software for teams and freelancers, available as a cloud service or self-hosted deployment. A live timer, drag-and-drop calendar, and weekly timesheet record work organized by client, project, task, and tag; projects can also have rates and budgets. Reports can be filtered by those categories and billable status, then shared or exported as PDF, CSV, or Excel. Invoices can be generated from billable time with PDF and structured e-invoice output, tax rates, discounts, and EU reverse-charge. The desktop app detects the active app and document, and pauses the timer when it detects idle time; that activity stays on the device until converted into a time entry. Desktop versions are offered for macOS, Windows 10/11, and Linux. The Professional plan is €8 a month when billed annually, excluding VAT, or €9 a month billed monthly, excluding VAT. The Open Source plan is free and includes self-hosted deployment.
