About Development & Code Tools

Developers reach for small utility tools dozens of times per day — formatting a JSON blob, decoding a JWT, generating a UUID, converting a cron expression to English. NoxaKit's Development & Code collection puts those operations one tab away, with no signup, no rate limit, and no code sent to a server.

**Who uses these tools?** Backend engineers use the JSON formatter, SQL formatter, YAML↔JSON converter, and regex tester. Frontend developers use the CSS formatter, Tailwind converter, flexbox generator, and CSS specificity calculator. Full-stack teams use the JWT decoder/builder, bcrypt tester, Base64 encoder, and ENV file parser. DevOps engineers use the crontab generator, cron explainer, Dockerfile generator, and gitignore generator. Security engineers use the hash generators, AES encrypt/decrypt, and RSA key pair generator.

**Common workflows** API debugging: paste raw JSON → prettify → diff against expected → validate against JSON Schema → copy clean output. Auth debugging: paste JWT → decode header and payload → inspect expiry and claims → rebuild with corrected payload. Database query: format SQL → check regex pattern in regex tester → test cron expression for scheduled job.

**Why no-upload matters for developers** Production tokens, API keys, and environment variables sometimes appear in the data being debugged. Browser-only processing ensures that a JWT or .env file never leaves the local machine during inspection.

**Subcategories** Code Formatting covers JSON, YAML, XML, SQL, HTML, CSS, JS prettifiers and minifiers. Encoding & Decoding includes Base64, URL encoding, HTML entities, and hex/binary converters. Code Analysis offers regex tester, CSS specificity, and JWT decoder. Code Generation includes UUID, cron builder, Dockerfile, gitignore, and JSON Schema generators. Utilities covers browser info, user-agent parser, HTTP headers, and screen resolution. Networking handles subnet, CIDR, IP conversion, and DNS formatting.
