Introduction to DevKit
DevKit is a privacy-first toolbox for developers who want fast answers without sacrificing control. Everything runs in your browser—no logins, no servers, just focused utilities that respect your workflow.
Why DevKit?
Context switching kills momentum. DevKit keeps essential tools at arm's reach so you can convert, check, optimize, and ship without leaving your browser or leaking your data. It's built by a developer who needed the same frictionless, private experience for daily work.
Built Around Four Pillars
Privacy by Default
Processing happens entirely in-browser. Your snippets, images, and tokens never touch a server.
Instant Feedback
No loading bars. DevKit responds as fast as you type, so you stay in flow.
Clarity First UI
Clean layouts and predictable actions keep the focus on your work, not the tool.
Free & Open
No paywalls or ads. DevKit is open source and always available when you need it.
How It Fits Your Day
DevKit is designed to be invisible until you need it. Pick a tool, drop in your input, and get a copy-paste-ready result.
- 1Choose a tool
Navigate from the catalog or search to jump straight to what you need.
- 2Work locally
Paste text, upload images, or tweak settings. Everything runs in-browser.
- 3Ship the result
Copy, download, or reuse outputs instantly without breaking your flow.
What You Can Do with DevKit
Convert & Validate
Format JSON, YAML, and XML, convert timestamps, encode/decode Base64, and keep data tidy before it hits your repos or APIs.
Generate on Demand
Spin up UUIDs, QR codes, passwords, placeholder text, and other building blocks without switching tabs.
Ship Web-Ready Assets
Extract, optimize, and convert images or SVGs, create React-ready components, and keep assets lightweight.
Check & Debug
Compare diffs, test regex, inspect JWTs, and hash content so you can verify changes before they ship.
Tech & Philosophy
DevKit runs on Next.js, React, TypeScript, and Tailwind. The tooling is lean so it stays fast, resilient, and easy to maintain. The promise: keep your data local, be transparent about how things work, and ship incremental improvements often.
About the Creator
DevKit is built by a full-stack developer who wanted a trustworthy toolbox that never phones home. It's crafted for teams that value privacy, speed, and quality over noise.
