CounterAPI is a REST API for tracking counts and metrics without running a database. Increment a counter with one call — through the JavaScript or Go client library, or the REST API directly — and watch it update on a real-time dashboard. Counters live in workspaces with public/private visibility and team access control.

The free tier includes 1,000 counts/day, 5 public counters, 5 workspaces, and 3 teams of up to 5 users each — no credit card required.
