Developer Tools

Utilities for developers and data people. Everything runs locally, so API payloads and tokens you paste never leave your browser.

Developer Tools: common questions

Is it safe to paste API responses or tokens?

Yes. The tools run locally in your browser and never send what you paste to any server.

Which JSON standard is used?

Strict JSON as defined in RFC 8259, so comments and trailing commas are reported as errors.
