KeyUp

What it does

KeyUp turns your keyboard into a game. A free Chrome extension that plays punch and kick sound effects as you type, with stadium crowd BGM and a KO finisher on Cmd+Enter.

Stadium crowd. Punch and kick SFX. KO on send. The original KeyUp experience. Retro 8-bit chiptune BGM builds as you type. Dark arcade atmosphere. New themes dropping regularly. Each one a different world to type in. Yes. The Fighting theme is free forever. Additional worlds (Arcade, etc.) may be offered as one-time purchases in the future. Browsers block audio until the page receives a user gesture. Click anywhere on the page once, then start typing. Also check the volume slider in the popup — dragging it to 0 silences everything. Any site where you can type — Gmail, Google Docs, Notion, Slack, Twitter/X, GitHub, VS Code for the Web, and so on. Some sites with strict Content Security…from keyup-extension.vercel.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.
