I built a free REST API for common dev tasks that usually require pulling in heavy dependencies or writing boilerplate.
Features include:
- URL shortener with click analytics
- QR code generation (PNG/SVG/data URL)
- Fake/mock data generator (person, address, email, company, etc.)
- JWT decoder, regex tester, password generator
- JSON diff/format/minify, YAML↔JSON, Markdown→HTML
- Base64, SHA256/MD5/SHA512 hashing, UUID v4
- Cron expression explainer, number base converter
- IP info, HTML tag stripper, list processor
No auth required for basic usage (rate limited). Pay 1 USDC on Base L2 for an unlimited API key.
Also available as a zero-dependency npm package: npm install conway-toolbox
