About MakeMyDev

Why this exists

Developers reach for small utilities dozens of times a day — format some JSON, decode a JWT, test a regex, generate a UUID. Most of the sites that show up in search results are plastered with ads, require an account, or silently upload your data to a server.

MakeMyDev is the alternative. Every tool processes data on your machine using JavaScript in the browser tab you already have open. Nothing leaves the page. There is no backend, no database, no user accounts, and no data collection beyond basic analytics (which you can opt out of).

How it works

Each tool is a self-contained client-side application. When you paste a JSON blob, encode a string to Base64, or build a cron expression, the work happens in your browser's JavaScript engine. The page never makes a network request with your input. You can verify this yourself by opening DevTools and watching the Network tab — you won't see anything leave.

The site is built with Next.js, TypeScript, and Tailwind CSS. It is deployed as a static site on Vercel.

What we believe

• Privacy by architecture. If data never leaves the browser, there is nothing to leak, breach, or subpoena. We don't want your data — we designed the system so we can't have it.
• No account walls. Developer tools should be available the moment you need them. Creating an account to format JSON is absurd.
• Fast and focused. Each tool does one thing well. No bloated dashboards, no onboarding flows, no upsells.
• Free. The tools themselves are never gated or degraded.

Available tools

MakeMyDev currently includes tools for JSON formatting, Base64 encoding, URL encoding, HTML entity encoding, text diffing, regex testing, UUID generation, cron expression building, test credit card number generation, QR code generation, JWT decoding, YAML/JSON conversion, timestamp conversion, and code syntax checking. More are on the way.
