KraiNode: JSON-RPC Playground

A browser-based JSON-RPC playground for testing endpoints, inspecting responses, and investigating request behavior.

GitHub Website

I built KraiNode to make JSON-RPC requests easier to reproduce and inspect in a browser. It provides a playground for sending requests to blockchain RPC endpoints and examining the responses and timing, so another engineer can repeat the same check.

Open KraiNode or explore the source code linked above.
