What it does

Every site blocker makes you maintain a list of "bad" sites. That list never ends. Lockby flips the model. Pick the 1-3 domains you need for your current task, set a timer, and everything else disappears. Non-whitelisted tabs get killed before the page loads. No loopholes. Want to quit early? You have to type a full sentence and wait 5 seconds. It's a speed bump between impulse and action. Built for ADHD brains and chronic tab-openers Works on Chrome, Edge, Brave, and Arc.

Lockby is a Chrome extension that locks your browser to only the domains you choose during timed focus sessions. Pick what you need, everything else disappears. Built for ADHD brains and chronic tab-openers.

Pick the domains you need for your task, set a timer, and everything else disappears. No blocklist to maintain. Just a whitelist of what matters right now. You sit down to do one thing. Ten minutes later you have 30 tabs open across 12 different sites and zero memory of what you were doing. Pick the sites you need for your task. Your email and a spreadsheet? Add both. Everything else disappears. Choose 5 minutes or 8 hours. Hit start and your browser locks down. A toolbar countdown shows how long you have left. Try to open Reddit. Go ahead. Lockby kills the tab before the page even loads. No willpower required. Traditional blockers make you maintain a list of bad sites. That list never…from lockby.app

  • I built a frontpage for personal blogs▲783

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
