Show HN: I built simple browser tools bcoz I'm tired of everything becoming SaaS
Hi HN,
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.

- sawarbandhe 8mo agoA bit more technical context: 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.
- aadesh56 8mo agoWhat's the monetization plan?
- sawarbandhe 8mo agoNo monetization plan right now. Just keeping it simple.
- f30e3dfed1c9 8mo agoThis is nicely done. Obviously haven't had time to check anything exhaustively but first impression is that it's very nice.
- sawarbandhe 8mo agoThank you :)
- XCSme 8mo agoLooks good (and AI generated). Do you use it yourself?
- sawarbandhe 8mo agoYes, I built it for myself first. The JSON, SQL Formatter, Text Diff and PDF tools were things I needed often, and I didn’t like uploading files or creating accounts for trivial tasks.
