DevPouch
Every dev tool. In your browser.
A growing pouch of 72 developer utilities that open instantly in a browser tab — formatters, converters, generators, image and PDF toolkits, network checks and more. Most run entirely on your machine: no upload, no account, no tracking.
72 tools, one tab
JSON, YAML, CSV and XML converters; hash, JWT and UUID generators; regex and cron testers; full image and PDF toolkits — 72 utilities across 14 categories, each a keystroke away.
Private by default
56 of the 72 tools never send your data anywhere — they run entirely in your browser. The 8 network tools (DNS, SSL, IP, SEO checks) and 8 opt-in AI assists are clearly badged, so you always know where your data goes.
Install it like an app
DevPouch is a PWA — install it to your dock and most tools keep working offline once they've loaded. Dark mode follows your system.
Built for flow
A ⌘/Ctrl-K command palette, pinned favourites, recent tools, and drag-and-drop file input. No sign-up, no cookies, no ads.
AI where it actually helps
A few tools offer an optional AI-powered assist — explain a regex, plan an image pipeline, or turn a screenshot of a table into clean CSV or JSON. Always opt-in, never automatic.
