Hi Product Hunt! I'm İlker, solo builder of Glowbit .
Glowbit turns any screen into a live LED sign. No special hardware, no complicated setup: open a link on a TV, pair it with a 4-digit code, and manage everything from one dashboard. Got more than one screen? Sync them into a single seamless video wall.
I've always had a soft spot for old-school LED signs, that warm glowing pixel charm. One day I caught myself thinking: why should that vibe stay stuck in the past when we're surrounded by TVs sitting idle most of the day? That's how Glowbit started.
It's running on restaurant menus 🍽️, hotel lobbies 🏨, build-status dashboards 💻 and office announcement boards 📢. Update from anywhere, instantly, or push live data in through the REST API.
Honestly, the hardest part was the video wall. Getting multiple screens, arranged horizontally and vertically, to stay in sync frame by frame took a lot of iteration (browsers measure the same text slightly differently, and that tiny difference turns into a visible offset across screens). Seeing a whole grid finally move as one canvas made it worth it.
Free plan, no card needed — try it on any screen you have. And for PH: code PH25 gets you 25% off, first 100 people.
Curious: if you had one always-on screen at work, what would you put on it? Happy to answer anything here today 🙌
