I built the most stripped-down API tester I could.
One feature only for v1: test an API.
No extra tabs, no clutter, no 47 settings.
Just request → response → done.
Open source too.

Would you actually use something this minimal day-to-day?
API Playground.
Not a mockup — a working tool I designed and built myself. Request builder, headers, live response preview.
Sharing screenshots first, full demo video to follow.
Built an interactive prototype for Synapse. If you're tired of staring at Alchemy/Infura dashboards trying to figure out what's actually wrong.
this is what monitoring should feel like.
