Aarunya Apps is live on Product Hunt!
16 free browser-based tools for developers and marketers. Zero uploads. Zero servers. Your data never leaves your tab.
Why we built this
Most developer tools upload your input to a server. We removed the server.
Architecture beats policy
"We don't log your data" is a policy promise. We removed the server entirely so there's nothing to log. Open DevTools → Network while using any tool — you'll count exactly zero outbound requests for your inputs.
Instant, no round-trips
Client-side processing means results appear in milliseconds. No API latency, no rate limits, no queues. Your .env is sanitized before you finish reading this sentence.
Works completely offline
After the initial page load, Aarunya Apps works with no internet connection. Paste secrets, decode JWTs, run OCR — all offline. Ideal for airgapped environments.
Free forever, seriously
All 14 core tools are free with no usage limits, no account, no credit card. We monetize with a $9/month Pro tier for AI features and saved history — not by mining your data.

Built for
“The .env sanitizer is the first tool I open when onboarding a contractor. Paste the file, redact everything, share the .env.example — 10 seconds.”
“I decode JWTs dozens of times a day for debugging. I'm not pasting tokens into jwt.io anymore. Aarunya's debugger uses Web Crypto locally and I can verify it in DevTools.”
“Our OCR vendor uploads documents to their servers. We switched to Aarunya's local OCR for redacting intake forms before they enter our document management system.”
Simple pricing
All 16 tools are free forever with no usage limits. Pro ($9/month) unlocks unlimited AI Regex, unlimited OG testing, and saved history.
