|---|---|---|
| Tagline | A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number. | VS Code fork that made AI coding actually work. |
| Category | Agents | Coding |
| Pricing | Free for consumers; standard Stripe per-transaction fees for merchants | Free + $20/mo Pro + $40/mo Business |
| Best for | Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data. | Developers. Non-developers who want to ship working code. |

| Kai's verdict | Stripe Link is the most credible first move toward a real agentic payment layer — the one-time-use card model is genuinely clever, and the existing merchant network gives it a head start no startup wallet can match. But the 'approve every transaction' UX will get old fast, and the hard part (autonomous spending with guardrails) is still on the roadmap. (Verdict pending Phi's full review.) | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
