Developer productivity is less about typing faster and more about eliminating friction: invalid JSON in a pipeline, a malformed JWT in staging, or regenerating UUIDs by hand. These seven utilities — all free on CryptoRedar — remove recurring bottlenecks from modern web workflows.
1. JSON Formatter & Validator
Paste API responses, minify for production, or prettify for code review. Our JSON Formatter catches syntax errors before they reach CI.
2. JWT Decoder
Inspect header and payload claims without sending tokens to external services. Debug expiry, issuer, and scope issues locally with the JWT Decoder.
3. Base64 Encoder / Decoder
Encode binary-safe strings for data URLs, basic auth headers, and test fixtures using the Base64 tool.
4. UUID Generator
Generate RFC 4122 v4 identifiers in bulk for database seeds and mock APIs via the UUID Generator.
5. Timestamp Converter
Convert Unix epoch values to ISO 8601 and local timezones when debugging logs — Timestamp Converter.
6. Hash Generator
Compute SHA-256 and other digests for checksum verification without installing OpenSSL locally.
7. Robots.txt Generator
Ship correct crawl directives on launch day with the Robots.txt Generator.
