Extensions · productivity & tools
Small tools. Big leverage.
Browser extensions and focused platforms built for creators, teams, and founders.
X Multiplayer
X Multiplayer is a Chrome extension paired with a real-time collaborative dashboard that automatically captures the posts you dwell on while browsing 𝕏. It turns solitary scrolling into a shared multiplayer experience where you and friends see each other’s live feeds side-by-side.
Flag standout posts into a shared top queue, save them to Raindrop.io, or spin them out into discussion tabs or external messaging. Flexible relays (PartyKit for the open internet, local WebSocket for LAN, custom WSS) make low-latency multiplayer effortless.
Additional polish includes 𝕏 logo enhancements, keyboard shortcuts (Alt+X), and a full history dashboard that works even offline until you connect a relay. Built for teams, researchers, and anyone tired of losing great posts in the algorithmic firehose.
