Compare AI tools

	OpenRouter S	GitHub Copilot B	Stripe Link A	Aider A
Tagline	One API, every model. Pay-as-you-go, no subscriptions.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	A digital wallet that lets AI agents spend on your behalf — without ever seeing your actual card number.	Terminal-based AI pair programmer. Git-aware, model-flexible.
Category	Dev Platform	Coding	Agents	Coding
Pricing	Pay per token — model-dependent	Free (limited) + $10/mo Pro + $19/mo Business	Free for consumers; standard Stripe per-transaction fees for merchants	Free (open source) + whatever API you use
Best for	Developers experimenting across models. Apps that want fallback logic.	Teams with GitHub already. Devs who don't want to change IDEs.	Anyone running autonomous AI agents (shopping bots, booking assistants, personal AI) who wants delegated payment capability without handing over raw card data.	Developers who want open-source tooling with full control.
Strengths	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Great enterprise story Works in your existing IDE Chat + autocomplete	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	Works in any terminal Auto-commits changes with meaningful messages Works with any model (Claude, GPT, local) Minimal learning curve
Weaknesses	Slight markup over direct API Some provider features not exposed	Less agentic than Cursor/Claude Code Model quality varies	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	Terminal-only Less agentic than Claude Code Setup on Windows is fiddly
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	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.)	A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
