Live updates
A deployed Cloudflare or Harper site stays connected to a live runtime, so some things change on a running site without a redeploy — today that's feature flags and live data.
Feature flags
Toggle features on a running deployment without rebuilding. Open File → Live & feature flags…, add a flag, and switch it on or off. On Cloudflare or Harper the change takes effect on the live site immediately; on other hosts it applies on the next deploy.
Gate anything behind a flag with the FlagGate brick (or bind any brick to the store key flag:<name>) —
see Bricks overview. Flags are also baked into each deploy, so first paint always
honors their current values.
Live data
Datasets can refresh on an interval and update live as the underlying data changes — see Build a dashboard.
Content & structure changes
Edits to the page itself — layout, copy, components — ship on your next deploy; re-deploying updates the same site in place. (Live push of full page changes to a running site isn't available yet.)
How it works
On Cloudflare or Harper, the deployed app keeps a live channel to a durable spine; flag flips and live data flow through it and re-render the affected pieces with no reload. Other hosts are static — redeploy to update.
Live flags + live data are Cloudflare and Harper only. A standard redeploy works on every host.
