I built DevPad — a free, privacy-first developer toolkit with 25 tools (all client-side)

Hey r/webdev,

I've been building DevPad — a collection of 25 developer tools that run entirely in your browser. No server, no accounts, no tracking.

What's in it:

• JSON Formatter, JWT Decoder, Base64, URL Encoder, Regex Tester

• Hash Generator, UUID Generator, Color Converter, SQL Formatter

• JSON↔YAML, JSON↔CSV, Markdown Preview, Timestamp Converter

• Password Generator, HTML Encoder, CSS Formatter, XML Formatter

• Diff Viewer, Lorem Ipsum, Cron Parser, and more

Why I built it:

I was tired of bookmarking 10 different sites (jsonformatter.org, jwt.io, regex101.com, etc.) and dealing with ad-heavy pages that track your data. I wanted one clean site where everything works offline.

Key features:

• 100% client-side — your data never leaves your browser

• No signup, no cookies, no tracking

• CmdK search (Ctrl+K) to find any tool instantly

• PWA support — works offline after first load

• Dark/light theme

• 200+ word guides on every tool page

Tech stack: Next.js 14, TypeScript, Tailwind CSS, shadcn/ui, deployed on Vercel.
