Sandbox
The real Gravit Verifier runs here, in your browser. Pick an example or paste your own artifact, and see what the claim may be called and why. Nothing you enter leaves your device.

Records must be signed by keys in the registry to count towards a Verified Fact. The examples are signed with public test keys from the verifier's test suite, so editing a signed field makes that record inadmissible: that is the point. Your own keys and registry will come with the hosted plans (planned).
Runs the verifier's Python code with Pyodide, which your browser loads from the jsDelivr CDN; what you enter stays in your browser. Source of the code shown here: verifier. Bundle with file hashes: bundle.json.
