About ToolsWalla
A fast, privacy-first collection of everyday tools for Techies, built by a Techie, for Techies.
Why ToolsWalla Exists
As a working Cyber security engineer, I use dozens of small utilities every day: formatting JSON from an API response, decoding a JWT to debug an authentication issue, generating a UUID for a test fixture, or comparing two config files. The problem is that most online tools for these tasks are bloated with ads, pop-ups, and — worst of all — many quietly send your data to a server. That's not acceptable when you're pasting production tokens, log files, or sensitive configuration.
ToolsWalla is my answer: a single, clean, predictable place for the tools I reach for most often, built with a strict rule — everything runs in your browser. No data leaves your device. Ever.
What Makes It Different
- 100% client-side. Open DevTools → Network tab. Click "Format" on the JSON tool. Zero network requests. Entire computation is local.
- No accounts, no paywalls, no limits. Use any tool as many times as you want.
- Fast. Next.js on Vercel's edge network. Pages load in under a second.
- Reliable. Uses well-tested open-source libraries (PapaParse, jsdiff, RFC 4122 UUID) rather than fragile custom code.
- Ad-supported, privacy-respecting. Ads pay for hosting; we never sell your data — because we never have it.
The Tools
Eight tools covering the most common daily tasks: JSON Formatter, JWT Decoder, UUID Generator, Unix Timestamp Converter, Base64 Encoder/Decoder, Log Analyzer, Text Diff Checker, and CSV ↔ JSON Converter.
More are planned based on what developers actually need. If there's a utility you find yourself searching for often, I'd love to hear about it.
The Tech
Built with Next.js 14, React 18, TypeScript, and Tailwind CSS. Statically generated where possible; interactive tools run as client-side React components. All parsing uses well-maintained open-source libraries with millions of weekly downloads.
