solidtime
Modern open-source time tracking for freelancers and teams, with projects, tasks, clients, rates, reporting, and PDF invoicing in one place.

solidtime is a modern open-source time tracking application built for freelancers, agencies, and teams. It combines time entry tracking with project organization, client management, and billing workflows in a single web app.
Key Features
- Time tracking with a fast, modern interface
- Projects, tasks, and client management
- Billable rates per project, member, organization, and more
- Roles and permissions for team collaboration
- Multiple organizations per user account
- Import from other trackers (including Toggl and Clockify)
- Billing, reporting, and PDF invoice generation
- Progressive Web App (PWA) experience for mobile devices
Use Cases
- Freelancers tracking billable hours per client and generating invoices
- Agencies managing projects, team access, and rates across multiple clients
- Teams centralizing time entry reporting for internal or client-facing summaries
Limitations and Considerations
- Some announced features may be marked as “coming soon” depending on the version (for example offline support and certain client templating features)
solidtime is a good fit for organizations that want a modern UX and strong core time-tracking features while keeping control via an open-source, deployable product. It is especially well-suited when projects, client billing, and permissions need to live in the same system.
