Good use cases

• Debugging API payloads and tokens locally
• Quick checksums and encoding during support work
• Formatting JSON before committing config
• Testing regex against sample logs

Alternatives (and when to pick them)

• Desktop apps — best for heavy daily editing with lots of files
• OS built-ins — fine for occasional jobs when you already know the workflow
• Upload-based websites — convenient, but avoid for sensitive inputs
• Toolkase browser tools — fast, private-by-default for one-off and recurring light work

Tips for developer utilities

• Never paste production secrets into a tool you have not verified is local-only.
• Prefer SHA-256 over legacy digests for new integrity checks.
• JWT decoding is for inspection — it does not prove a token is valid.
• Minifiers here are best-effort; run your production bundler before shipping.
