timeBuzzer is a time-tracking platform with desktop, mobile and web apps and an optional physical Desktop Buzzer: a button on the desk that starts and stops the timer and shows by LED whether time is being recorded. It is aimed at freelancers, teams, small businesses and larger organisations, such as agencies, IT service providers, accountants and lawyers. Features include unlimited customers, projects and tasks, analytics, reports with your own logo, export to Excel or CSV, team roles and permissions, and an open API with many integrations.
timeBuzzer is operated by timeBuzzer GmbH in Saarbrücken, Germany. According to the vendor, it deliberately chose Germany as its server location and keeps all data in ISO 27001-certified data centres; the link to the certification points to Hetzner's documentation, but the vendor does not name the hosting provider in the text. Data is synchronised online. timeBuzzer is not open source and no self-hosted option is documented.
