About DevStash
DevStash is a free collection of online developer tools built for speed, privacy, and convenience. Every tool runs entirely in your browser — no data is sent to any server, no sign-up is required, and there are no paywalls.
Our Mission
Developers search for tools like JSON formatters, regex testers, and Base64 encoders dozens of times each week. Too often, the top results are slow, cluttered with pop-ups, or require sign-ups. DevStash was created to solve this — we provide fast, reliable versions of essential developer utilities in one clean, accessible place.
Our goal is simple: be the first bookmark every developer reaches for when they need a quick utility. Dark mode by default, keyboard shortcuts built in, and zero friction from landing page to result.

Why DevStash?
100% Client-Side
Your data never leaves your browser. Every tool processes input locally using JavaScript — nothing is uploaded, stored, or logged on our servers. This makes DevStash safe for working with sensitive data like API keys, tokens, or proprietary code.
Fast & Lightweight
Each tool page loads under 40 KB of JavaScript. We use static site generation with Astro, so pages load instantly as pre-rendered HTML. No heavy frameworks, no loading spinners, no waiting.
Developer-Friendly Design
Dark mode by default, a command palette (Ctrl+K) for quick tool search, copy buttons on every output, and responsive layouts that work on any device. DevStash is designed by developers, for developers.
Free & No Sign-Up
All tools are completely free with no account required. No rate limits, no feature gates, no premium tiers. Just open the page and start using the tool.
How It Works
DevStash is built as a static site using Astro, a modern web framework that generates pre-rendered HTML at build time. Interactive tool components are built with Svelte, which compiles to lightweight vanilla JavaScript — no virtual DOM, no runtime overhead.
When you use a tool, all computation happens in your browser's JavaScript engine. For example, the JSON Formatter parses and formats JSON using native browser APIs. The Hash Generator uses the Web Crypto API for cryptographic hashing. Nothing is sent to an external server.
Who Maintains DevStash
DevStash is built and maintained by Sukeesh, a software developer passionate about building useful tools for the developer community. The project is actively developed with new tools and improvements being added regularly.
