Tagline	Cognition Labs' autonomous coding engineer.	A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number.	Run LLMs locally. One-line install, GUI optional.	OpenAI's browser agent. Clicks and types on websites for you.
Category	Agents	Agents	Dev Platform	Agents
Pricing	$500/mo	Free for consumers; standard Stripe per-transaction fees for merchants	Free + open source	Included with ChatGPT Pro $200/mo
Best for	Engineering teams offloading tickets. Ops/platform work.	Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data.	Devs wanting offline/local LLMs for privacy or experimentation.	Power users willing to pay $200/mo for a browser bot.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	First mainstream wallet with a built-in agent authorization layer — AI agents get one-time-use cards, not your real credentials OAuth-based approval flow means you review every agent spend request before payment credentials are shared 250M+ existing Link users means instant network coverage at hundreds of thousands of Stripe-powered merchants Developer-friendly: agent builders can use Link's wallet infra instead of rolling their own payment rails Subscription tracking, auto payment-method updates, and 90-day purchase protection bundled in	Run Llama, Mistral, Qwen, etc. on your laptop Simple CLI + API Hardware-aware (picks the right quant)	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	Stablecoin, agentic token, and BNPL agent-payment support is still 'coming soon' — traditional cards only at launch Per-transaction approval flow can be tedious for high-frequency agent tasks until spending-limit presets ship Merchant adoption for agent checkout paths is still early; real-world agentic commerce coverage is thin	Needs beefy laptop for larger models Speed way behind cloud APIs	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	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 local inference. If you care about privacy or want to tinker, install this today.	B-tier. Still early. Manus is more flexible for less money.
