JWT Decoder

Inspect header and payload locally. Your token never leaves the browser.

Compare two texts or code blocks with clear additions and deletions.

Base64 Encode / Decode

Encode or decode text safely with Unicode support.

Cron Generator

Build cron expressions or turn 0 0 * * * into plain English.

Why DevsDrill?

Every tool runs in your browser. No accounts, no server-side processing of secrets — ideal for JWT tokens, diffs and encodings.

Which tool should I use?

Decode JWTs without sharing tokens. Diff two snippets before a commit. Encode Base64 payloads. Humanize cron for ops and CI.

Private by design

Developer utilities often handle secrets. DevsDrill never sends your inputs to our servers.

FAQ
