Chat with Artifacts & Previews

Threads, sandboxes, preview URLs, and how artifacts reach you.

  1. Start a thread in Chat. Threads carry context across messages (v2 chat API: 41 operations under the v2-chat tag in the generated reference).
  2. Ask for something executable. When a task needs code, Flowmanner runs it in a sandbox bound to your account — chat-created sandboxes register to their owner (fixed 2026-08-25, commit a838d249), so no one else can reach your runtime.
  3. Open previews safely. Live previews are served from dedicated *.preview.flowmanner.com origins, isolated from the main app by Content-Security-Policy frame-src https://*.preview.flowmanner.com (frontend/next.config.ts). Only embed previews from that domain.
  4. Collect artifacts. Files produced in the sandbox are delivered as chat artifacts — download them from the message they belong to.
