Use cases

Know what a string can do before another parser decides for you.

tryb.dev is a local-first inspection bench for the ambiguous material developers handle every day. Start with the workflow that matches the boundary you are reviewing.

Before execution

Inspect an unknown string safely

Identify pasted tokens, hashes, encoded blobs, URLs, certificates, and configuration values before they reach a terminal or production system.

Open the analyzer Decode Base64

Authentication

Review token and key material

Decode JWT claims, surface unsafe algorithm choices, check bounded weak-secret candidates, and inspect RSA or X.509 metadata without uploading secrets.

Inspect a JWT Analyze certificates

Parser boundaries

Find interpretation disagreements

Detect duplicate JSON keys, Unicode control characters, HTTP request ambiguity, and files accepted as multiple structural formats.

Detect JSON differentials Compare Unicode normalization Check polyglot files

Configuration review

Catch risky values before commit

Examine environment files, permissions, network addresses, ports, serialized payloads, and secret-shaped values while keeping the input local.

Analyze environment files Inspect chmod values
