Fishtank
An open source tool that turns API monitoring into a living fish tank.

Monitoring, made fun.
Monitoring API endpoints is often tedious and overlooked—until something breaks. This open source tool transforms endpoint health into an animated fish tank, making system status easy to understand at a glance for both technical and non-technical team members.
View on GitHub →Every endpoint is a fish.
Point Fishtank at your API endpoints and each one becomes a fish in an animated aquarium. As long as an endpoint is healthy, its fish keeps happily swimming.
A simple config page keeps setup lightweight — add your endpoints and the tank takes care of the rest.


Bad news, delivered gently.
When an endpoint goes down, its fish floats belly-up — a status moment that both technical and non-technical teammates understand instantly, no dashboards required.
The playful brand carries through the whole experience, from the aquarium to the logo, type, and color system.
