Pick two tools. Watch the data flow between them.

8 tools in a selection grid. Pick a source and destination, and the engine fires a pre-mapped API sequence with variable timing (GETs are fast, POSTs take longer). Each call logs with color-coded HTTP method badges, real endpoint paths, and expandable JSON payloads showing request and response bodies. A scenario context card sets the business narrative before each sequence starts. Unmapped tool pairs generate plausible API calls from tool-specific endpoint patterns. Connection animation, completion summary cards, and progressive messaging build across runs. All data is client-side.

8 tools (Gmail, Slack, Google Sheets, HubSpot, Notion, Stripe, Twilio, Calendly) with 8 pre-built integration pairs. Select a source, watch valid partners glow Copper, pick a destination, and click Connect. A narrative context card appears, then API calls fire with variable timing. Click any expand arrow to see the full JSON payload. After completion, a trigger-to-outcome summary card shows what happened. Run all 8 to see cumulative stats. Unmapped pairs still show real-looking API sequences.
