Agentcard tech stack

Resend

“Resend handles all our transactional email — magic links, card notifications, receipts. Clean API, reliable delivery, and a developer experience that feels like it was built by people who actually send email.” — the maker, Sep 2026 ↗

Stripe

“Stripe Issuing is the backbone of AgentCard. We create virtual Visa cards in milliseconds through their API. The reliability, documentation, and developer experience are unmatched — there was never a serious alternative.” — the maker, Sep 2026 ↗

Claude

“Claude is the AI model behind our smartest agent integrations. Anthropic's focus on safety aligns perfectly with how we think about giving agents financial capabilities — powerful but controlled.” — the maker, Sep 2026 ↗

Railway

“Railway makes deploying and scaling our backend effortless. Push to main, it's live. No Dockerfiles to debug, no infra to babysit. We went from zero to production in an afternoon.” — the maker, Sep 2026 ↗

PostHog

“PostHog gives us full visibility into how agents and users interact with AgentCard. Event tracking, session replays, feature flags — all self-serve, no sales calls. Perfect for a fast-moving team.” — the maker, Sep 2026 ↗

Claude Code

“Claude Code is how we build AgentCard. It's also one of our most popular integrations — agents using Claude Code can create and use virtual cards through MCP without leaving the terminal. We use it, we build for it.” — the maker, Sep 2026 ↗

Vercel

“Vercel hosts our landing page and dashboard. Instant deploys, perfect caching, zero config. It just works — which is exactly what you want when you're focused on building the product, not the infra.” — the maker, Sep 2026 ↗
