What is Lasius?
Lasius is an open-source time-tracking tool that runs on your own infrastructure. Developers, freelancers and teams use it to record working hours per project and task, analyse them and use the data directly for client billing. Because all data stays stored locally, Lasius falls into a category that is especially relevant for privacy-sensitive environments: self-hosted tools with no cloud dependency and no ongoing licence costs.
Core features
- Time tracking at the level of individual projects and tasks
- Billing of client projects based on actual recorded working time
- Productivity analysis and time auditing for teams
- Fully self-hosted, no data on third-party servers
- No subscription costs, as it is open source
Who is Lasius for?
Anyone familiar with Docker who runs their own server environment can set up Lasius without much effort. For everyone else, the difficulties start at installation. Without experience in self-hosting setups, the foundation needed to run and maintain the system is quickly missing.
The target audience is correspondingly well defined: technically proficient freelancers, small agencies and developer teams that deliberately want no SaaS solution. Organisations with strict data protection requirements that are not permitted to outsource time tracking to external services also get what they need here. Anyone who simply wants to track hours quickly without dealing with infrastructure is better served by a hosted alternative.
Context & alternatives
In the self-hosted time-tracking segment, Lasius is one of the few options explicitly aimed at freelancers and teams rather than just individuals. Commercial alternatives such as Toggl Track or Harvest offer more out-of-the-box integrations and broader support, but tie users to cloud infrastructure and monthly fees.
Anyone who, for regulatory or principled reasons, cannot transmit time data to external services will find in Lasius one of the few open-source options that combine project billing and team reporting in a single tool.
