The Take

Bundles a predictable but genuinely handy set of small tools — URL shortener with analytics, QR (PNG/SVG/data URL), fake-data generator and JWT/regex helpers — behind a no-auth REST API and a zero-dependency npm package. The on-chain 1 USDC unlimited-key option is a smart monetization experiment, but this space is crowded: reliability, clear rate limits and docs will determine whether it becomes a daily go-to or just another utilities site.

Target Audience

Backend/frontend engineers, QA and SREs, hobbyist developers who need lightweight utilities via API or an npm package

Post Description

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

Devly – 50 developer tools in a native macOS menu bar

Everything lives in the menu bar and is keyboard-first (⌘K to search, ⌘↵ to process), so common tasks — JSON/YAML/XML formatting, JWT inspection, hashing, color conversion, regex testing — feel immediate. The author emphasises pure SwiftUI and sandbox-compatible implementations rather than a web wrapper, which is a small but meaningful engineering win for responsiveness and privacy. It's not a novel idea — apps and web tools already do this — but the native UX and offline clipboard-first flow make it genuinely useful.
