🥒 cucumbero

Yet another vegetable-themed timer + website blocker to help you focus, maybe. You set a timer, and the extension blocks your chosen websites, while you're trying to finally get some work done.

Vibe-coded with Claude 5, mostly.

The Chrome Web Store page

Features

• Minimalistic. Just a timer and a blocklist.
• Set a length and the timer counts down. Set it to 0 and it counts up until you stop it.
• Covers blocked tabs with an overlay instead of redirecting them, so pages keep their state. When the session ends, you'll find them exactly as you left them.
• Fullscreen and picture-in-picture get closed too, so a video can't play over the top of the overlay. Sound carries on though, and keyboard events go through.
• Keyboard support: type a number or use the arrow keys to set the session length, then press Enter to start the timer. (You can also assign a shortcut under chrome://extensions -> Keyboard shortcuts)
• Catches tabs you already had open, ones you open later, and ones that run into a blocked site mid-session.
• Add the current tab's domain to the blocklist in one click, even during a session.
• Subdomains get blocked automatically, e.g. blocking reddit.com also blocks old.reddit.com. You can also block a specific path, e.g. reddit.com/r/quick_dopamine.
• A 10-second break button in case you need to pause a video or leave a call.
• Shows the remaining time on the toolbar icon.
• No sign-in, no analytics, no network requests, no remote URLs anywhere in the code. Nothing leaves your browser.

Install

1. chrome://extensions
2. Turn on Developer mode (top right)
3. Load unpacked → select this folder
4. Pin it to the toolbar

Known limits

• A speed bump, not a cage. Anyone who disables the extension, uses incognito, or a different browser gets right past it. That's fine. It's built to beat your reflexes, not your intent.
• Some pages can't be covered: chrome://*, the Chrome Web Store, the PDF viewer, and other extensions' pages. Chrome forbids injection there.
• Audio keeps playing behind the overlay. This is inherent to the overlay-instead-of-redirect approach. So you can listen, but not watch. Depending on your case, this can be a feature or a deal-breaker.
• Keyboard events go through so you can still, say, pause/unpause a youtube video using K without even using a 10-second break.

Two things in here aren't mine:

Nunito, bundled as fonts/nunito-var.woff2 and used for the wordmark, the timers and the overlay title. SIL OFL 1.1, © 2014 The Nunito Project Authors; the licence travels with it in fonts/OFL-Nunito.txt, as the OFL requires.

The cucumber, rendered by tools/make-icons.py from the 🥒 glyph of Noto Color Emoji — © Google Inc. 2013–2017, Apache License 2.0. That font isn't bundled and none of its files ship here: the icons are images produced with it, so no OFL notice is owed for them the way one is owed for Nunito above.
