Resistor

Block distracting websites
behind a moment of thought.

Resistor puts YouTube, Reddit, X and anything else you name behind a short, deliberate pause — long enough to notice you were drifting, short enough that you do not start hating the tool and uninstall it.

How it works

  1. Pick your sites

    Choose from the usual time sinks or add your own. Chrome asks permission for exactly those sites — Resistor never requests access to the rest of the web.

  2. Meet the pause

    Open a blocked site and the page never loads. You get a calm screen instead: what you tried to open, your streak, and one question — what were you about to do?

  3. Choose on purpose

    Go back to work in one click, or let yourself in for a few minutes. Either way it was a decision rather than a reflex, and access re-blocks itself automatically.

What you get

⏱️

Timed access that closes itself

Let yourself in for five minutes without disabling anything. When the timer ends the block comes back on its own — no willpower required at the far end.

🎚️

Three levels of resistance

Gentle for a nudge, Focused to make you write why you are there, Locked when you want no way through at all. Set it per site.

📅

Work-hours schedules

Block only when it matters. Outside your hours everything is open, so evenings and weekends stay yours.

🔥

Streaks and a daily allowance

See how often you turned back, and cap how many minutes a day you can spend letting yourself through.

🛡️

It actually blocks

The page is stopped before it loads, so nothing renders and no video starts playing underneath a pop-up. There is nothing to click away.

🔒

Nothing leaves your browser

No servers, no analytics, no account. Settings live in your own Chrome sync storage and that is the entire data story.

The permissions question

Most website blockers ask to read and change all your data on all websites the moment you install them. Resistor asks for nothing at install. When you add a site, Chrome asks whether Resistor may access that one site — and that is the only access it ever holds.

Remove a site from your list and the permission is handed straight back. You can check any of this yourself on chrome://extensions, and the privacy policy spells out the rest.

Questions

Is Resistor really free?
Yes. Every feature, no account, no paid tier, no upsell inside the extension.
Does it track my browsing?
No. There are no servers to send anything to. Resistor only holds permission for the sites you explicitly chose to block.
Can I get past a block when I genuinely need to?
Yes — unless you picked Locked. Gentle and Focused both let you grant yourself timed access, and it closes itself again automatically.
What happens if I uninstall it?
Everything goes with it. The permissions are revoked by Chrome and your settings are removed along with the extension.
Does it work in Incognito?
Only if you turn that on for Resistor at chrome://extensions. Chrome keeps extensions off in Incognito by default.
Will it block sites in other browsers?
No — a Chrome extension can only govern Chrome. If you need blocking across your whole machine you want a system-level tool instead.

Built by TechNerdXp

I build small, careful browser extensions and web tools — the kind that ask for the least access they can get away with and still do the job properly. Resistor is free and always will be.

If you need something similar built, I take on client work: find me on Upwork or say hello on X.
