Store Builder runs on your own machine — the client starts it, so there is no endpoint to ping. 7 104 installs a week from npm. Last commit 30 Oct 2026.
Design, fill with real store data, render and publish Store Builder pages from an AI agent.
Nothing serious here today
Today is the operative word: we check Store Builder every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
