OneDevToolkit
Free Developer Tools
Chain local tools into recipes, keep secrets on your device, and prove it with privacy receipts. 300+ client-side developer utilities nothing uploaded.
I got tired of pasting JWTs, client PDFs, and HAR files into random “free online tools” and hoping they weren’t logging anything.
So I built OneDevToolkit — a set of developer utilities that run entirely in the browser. Your files/text stay on your device; core tools don’t upload to a server.
What it covers so far:
• Format / validate JSON, HTML, CSS, JS, YAML
• PDF merge, compress, protect, redact
• Image compress / resize / convert
• JWT decode, regex, Base64, hashing, API helpers
• AI prompt + token/cost helpers
• Recipe Studio to chain tools together
• Privacy receipts (proof that processing stayed local)
No ads. Core tools aren’t behind a paywall.

I’d genuinely like feedback from other devs:
1) What’s the first tool you’d trust only if it stayed local?
2) What’s missing that you still have to upload somewhere else?
3) Anything confusing on first use?
Happy to take feature requests.
