The web,minus everythingyou didn't ask for.

Null is a browser built on removal. Ads, trackers, cookie walls, phishing — blocked on your device before they ever load. What's left is the page you actually wanted.

What Null removes

A feature list that's a receipt.

Most browsers compete on what they add. Null competes on what it takes away — the mark is ∅, the empty set, because the right amount of junk reaching you is none.

Where your data goes

Different sites. Same trackers, every time.

Open a news page, a shop, a recipe — behind each one, the same handful of ad-tech servers gets told you were there. This is that wiring, and the exact spot where Null cuts it: on your device, before your data leaves.

without null — every page phones the same servers

The morning paper, quieter

Every new tab keeps score for you.

We took a quick lap through three news homepages and let the dashboard do the counting — what got stopped, what it saved, who tried hardest to follow along. It all lives in one small file on your disk, and deleting it is allowed.

CNN.com open in Null Browser with 38 ads and trackers blocked on the page — edition.cnn.com — **∅ 38 blocked** on one page

The Verge open in Null Browser with 15 ads and trackers blocked — theverge.com — **∅ 15 blocked**, reading undisturbed

Times of India open in Null Browser with 8 ads and trackers blocked — timesofindia.com — **∅ 8 blocked**, no banner walls

The walkthrough

Two minutes of quiet, on tape.

A full lap of Null doing its job — real sites, live counters, and all the noise that never showed up. Nothing loads from anywhere until you press play.

Show me how

Three moves. That's the whole manual.

No setup wizard, no extension store, no filter lists to pick. Install it and it's already doing its job.

01 · INSTALL & OPEN

Every tab starts at your scoreboard

Blocking is on from the first second — nothing to configure.

02 · GO WHERE YOU ALWAYS GO

The shield counts what didn't load

That little ∅ is the whole story — 38 things just didn't happen. Site misbehaving? Click it and allow that site for 30 minutes — blocking switches itself back on when time's up.

03 · OPTIONAL: GLOAT

Flip "Show what Null hid"

A setting for the curious: every emptied ad slot signs its work.

Local by design

There is no Null cloud. There isn't even a Null server.

A privacy browser that phones home isn't one. Here's the complete journey of your browsing data:

Your devicepages · history · stats · filters ——→ ∅ nowherethat's the whole diagram

Blocking happens on-device

Filter lists download to your machine and every request is checked locally — nothing about your browsing goes out for "analysis."

No account, ever

Nothing to sign up for, nothing to log in to, nothing to breach. Install and browse.

Safe-browsing, still local

Known phishing and malware domains are checked against lists on your device — not by sending your URLs to someone's API.

The fine print, voluntarily

What we won't promise you.

01Some video ads are unblockable — for everyone. Platforms like YouTube can stitch ads into the video stream itself. No browser or blocker on earth removes those. Null detects them and auto-skips instead, so you see seconds, not minutes.
02Windows may warn you on install. Null is a young project and our code-signing certificate is still pending, so SmartScreen shows an "unknown publisher" notice. That's Windows being cautious, and we'd rather explain it than pretend it won't happen.
03It's early. Null is in active development and updated often. If something breaks, the fix ships fast — new versions land right here. (One-click auto-update is still being wired up; when it's live, the release notes will say so.)

Free. No account. One installer, and the noise stops.
