Real-time & collaboration

Bricks that update live — from shared editing to streaming data to flag-gated sections.

Collaborative

  • CollabText — a shared text area; every keystroke merges live across everyone viewing it.
  • CollabChat — a shared chat box; post a message and everyone sees it immediately.

These build on the same real-time runtime as collaboration and live updates.

Streaming

  • LiveFeed — a live metric with a sparkline, fed from a server-sent stream.
  • CryptoChart — a live cryptocurrency price chart (streams over WebSocket) showing price, 24h change, and a rolling line.

For your own live data, use a dataset with a refresh interval — see Datasets & filters.

Feature-gated

  • FlagGate — renders its children only when a feature flag is on (or off, with invert). On Cloudflare or Harper deployments a flag flip takes effect live, with no redeploy. Use it to roll a section out gradually or run an experiment.

Wrap a new section in a FlagGate tied to a flag like beta_banner, deploy, then flip the flag from File → Live & feature flags… to reveal it to everyone — instantly on Cloudflare or Harper.
