PrimeTime stands on open-source work done by people who shared their fire. If PrimeTime is useful to you, the best thanks you can give is a star on the projects that made it possible.
The engine under the hood
Traggo pioneered tag-based time tracking, and PrimeTime Server is built from its internals, extended under AGPL 3.0 to enhance the label-based workflow UX — The PrimeTime way. Traggo's data model is the foundation we build on. Without it there'd be no PrimeTime.
The spark that guides us
Prometheus made labels the primitive for observability at scale: every metric carries key: value dimensions you can slice and aggregate any way you like. PrimeTime organizes your time with the same principles in mind, whether you're starting your first project or managing dozens.
Stars are the currency of open source — they signal that work matters and help others find it. A star on Traggo and Prometheus costs nothing and keeps the fire burning for the next person who needs it.
PrimeTime and this site are assembled from a lot of excellent open-source work.
