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

[sawarbandhe]

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.

A 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.

This is nicely done. Obviously haven't had time to check anything exhaustively but first impression is that it's very nice.

Thank you :)

Looks good (and AI generated). Do you use it yourself?

[sawarbandhe]

Yes, 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.

What's the monetization plan?

[sawarbandhe]

No monetization plan right now. Just keeping it simple.
