Stacklink — Products

2One run, dissectedInstead of six separate demos, one ask crosses all six products as stations — trigger to record. The detail line narrates each hop with real keys and honest numbers; the amber station is the approval gate doing its job.

One run, all six

Watch one ask cross the whole stack.

A payment fails at 02:14. By 02:15 the reminder is drafted, held, approved, and on the record — every product touched once, in order.

Connections outlive the client.

Swap Claude Code for Cursor tomorrow, or ship your own app next quarter — your users' connections, their memory, and your rules stay exactly where they were. They live with Stacklink, not with the agent.

✓Same endpoint, every client — nothing to re-integrate.

✓Nobody re-connects an account because you changed agents.

✓Memory and the record carry over, per user.
