About DevPocket
DevPocket — 49 tools, built by one developer.
Sourabh Kumar
Backend Developer
I build tools to remove the small daily frictions of backend work.
Why this exists
DevPocket started as a scratch-your-own-itch project: too many browser tabs open on formatter sites, cron decoders and "what does HTTP 409 mean again?" references — most of them slow, ad-heavy, or quietly uploading whatever you paste. So this one runs entirely in your browser. No backend, no analytics, no network calls. Your data never leaves the tab.
Nothing is uploaded
Every tool runs as JavaScript in your tab. There is no backend, no analytics and no network request — paste a production token or a customer payload without thinking twice.
Fast, and stays fast
Routes are code-split, so opening the SQL formatter never slows down the JSON one. No ads, no cookie banners, no consent dialogs.
Keyboard-first
Press ⌘K to jump to any tool, ⌘\ to collapse the sidebar. Built for people who would rather not reach for the mouse mid-task.

FAQ
Who built DevPocket?
Sourabh Kumar, a backend developer in India. It started as a set of tools he kept re-opening other sites for, and turned into one place that does them without an upload step.
Why does everything run in the browser?
Because the inputs are usually production payloads, tokens and customer data. A tool that posts them to a server asks you to trust that server; one that never sends them removes the question.
Is it open to suggestions?
Yes. The tools here exist because they came up in day-to-day backend work, so a gap someone else hits is worth hearing about.
