Over the last few years I’ve noticed something odd:
You now need an account to merge a PDF. Or format JSON. Or generate a QR code.
For utilities that can run entirely in the browser.
Many of these tools:
Upload files unnecessarily, Inject heavy ads, Track usage aggressively, Gate basic functionality behind email walls.
As a developer, this started bothering me more than it should have.
So I built my own versions.
Bitlist is a collection of browser-based utilities where:
No signup is required, No ads are shown, No popups exist, No tracking or monitoring scripts are included.
If something can run client-side, it runs locally
This isn’t a growth experiment or a funnel. It’s just a clean toolbox for simple tasks.
Current tools include:
JSON formatter / validator, PDF merge, WebRTC leak test, Internet speed test, QR code generator, Base64 / UUID / converters, It will remain ad-free and tracking-free.
Would appreciate feedback on:
Performance, Security concerns, UX improvements, Missing utilities.

Tools like JSON formatting, validation, Base64, UUID generation, and most converters are processed entirely client-side using plain JavaScript.
There are intentionally no ad networks, no analytics scripts, and no tracking pixels. I wanted the site to load fast and do one thing well.
If anyone spots architectural issues, edge cases (especially large payload handling), or security concerns, I’d genuinely appreciate the critique.
