Editorial developer utilities
A browser-first desk for the small tasks that break flow.
Format JSON, decode JWT payloads, generate UUIDs, convert timestamps, encode Base64, and test regex patterns without leaving the page or shipping your data to a server.
Tool index
Six precise utilities, each with context and examples.
The first release is intentionally narrow. Every page combines an immediately useful tool, clear usage guidance, FAQs, and internal linking so the site can grow without turning into a shallow list.
JSON Formatter
Format, minify, and validate JSON directly in the browser with readable error feedback.
- Pretty-print or compact valid JSON
- Inline validation feedback for malformed input
JWT Decoder
Decode JWT header and payload in the browser to inspect claims, timestamps, and token metadata.
- Decode header and payload locally
- Readable summary for time-based claims
UUID Generator
Generate UUID v4 values in the browser for database seeds, test fixtures, and identifiers.
- Uses the browser crypto API
- Generate 1, 5, or 10 values at once
Timestamp Converter
Convert Unix timestamps, ISO strings, and date text into UTC and local time representations.
- Detects 10-digit and 13-digit Unix values
- Returns UTC and local time together
Base64 Encoder
Encode UTF-8 text to Base64 or decode Base64 back into readable text directly in the browser.
- Supports UTF-8 text
- Fast encode and decode modes
Regex Tester
Test regular expressions with flags, inspect matches, and review captured groups against sample input.
- Pattern, flags, and test text in one place
- Returns match positions and groups
Local-first
Your input stays in the browser unless you choose to copy it out.
That matters for JSON debugging, token inspection, and regex experiments. The site is designed around small, trustworthy tasks: accurate transforms, fast feedback, readable outputs, and enough surrounding explanation to be useful for both repeat visits and search discovery.
