Solidtime is an open-source time tracking application designed for freelancers and agencies that need to track billable hours, manage clients and projects, and generate reports, without paying for a closed-source SaaS subscription.
Founded around 2024 and based in Vienna, Austria, Solidtime is released under the AGPL-3.0 license with its full source code on GitHub. It can be self-hosted for free indefinitely, or used through Solidtime's managed cloud offering.
Key Features
Solidtime tracks time entries against clients, projects, tags, and tasks, with support for billable rates so freelancers and agencies can invoice clients accurately based on logged hours.
The Professional plan adds team-level access management at both the project and organization level, invoicing, project and task estimates, time entry rounding, and exportable PDF or shareable reports, making it suitable for small agencies as well as solo freelancers.
Pricing
Solidtime's cloud pricing has two tiers: Solo, which is free and aimed at freelancers tracking their own time, and Professional, priced at 8 euros per user per month billed annually or 9 euros per user per month billed monthly, aimed at teams that bill clients and need access control.
Because Solidtime is open source, self-hosting the software remains free indefinitely under the AGPL-3.0 license. A separate on-premise pricing structure covers organizations that want commercial licensing terms or support beyond the free self-hosted option.
Key Features
Time Entry Tracking — Log billable and non-billable time against clients, projects, and tasks with a simple, modern interface.
