The terms of 15 July 2025 call the service an early version provided as is, with no uptime commitment below Enterprise.\n\n**Keycard.** Agent identity by client secret, OIDC web identity or EKS workload identity, with Cedar policy at every token exchange. Early Access with sign-up by request, and no terms of service page.\n\n## Before you call either\n\n### Arcade.dev\n\n1. Call `POST /v1/tools/authorize` first and send the user the returned URL when the status isn't completed\n2. Pass a stable user ID from your own database as user_id, never a shared value\n3. Read retry_after_ms on an UpstreamRateLimitError and wait that long before calling again\n4. Register your own OAuth app and a custom user verifier before real users sign in, because the default apps only accept members of your Arcade project\n5. Revoke a user's access with `DELETE /v1/admin/user_connections/{id}`\n\n### Keycard\n\n1. Set audience to the server's registered resource identifier, or the verifier accepts tokens minted for any resource in the zone\n2. Check `AccessContext.has_errors()` after a grant, since the SDK never throws on a failed exchange\n3. Treat `insufficient_authorization` on the token endpoint as a revoked or missing grant and stop, not retry\n4. Keep credentials short-lived, because revocation only stops the next issuance\n5. Pin keycardai-mcp to a major version, since 1.0.0 and 2.0.0 shipped a day apart\n\n## Other comparisons with Arcade.dev or Keycard\n\n- [Arcade.dev vs Auth0 for AI Agents (Token Vault)](https://www.anchorterminal.com/compare/arcade-vs-auth0-ai-agents.md)\n- [Arcade.dev vs Descope Agentic Identity Hub](https://www.anchorterminal.com/compare/arcade-vs-descope-agentic-identity.md)\n- [Arcade.dev vs Nango](https://www.anchorterminal.com/compare/arcade-vs-nango.md)\n- [Arcade.dev vs Scalekit AgentKit](https://www.anchorterminal.com/compare/arcade-vs-scalekit-agentkit.md)\n- [Arcade.dev vs Stytch Connected Apps](https://www.anchorterminal.com/compare/arcade-vs-stytch-connected-apps.md)\n- [Arcade.dev vs WorkOS Pipes and Agents](https://www.anchorterminal.com/compare/arcade-vs-workos-pipes.md)\n- [Auth0 for AI Agents (Token Vault) vs Keycard](https://www.anchorterminal.com/compare/auth0-ai-agents-vs-keycard.md)\n- [Descope Agentic Identity Hub vs Keycard](https://www.anchorterminal.com/compare/descope-agentic-identity-vs-keycard.md)\n- [Keycard vs Nango](https://www.anchorterminal.com/compare/keycard-vs-nango.md)\n- [Keycard vs Scalekit AgentKit](https://www.anchorterminal.com/compare/keycard-vs-scalekit-agentkit.md)\n- [Keycard vs Stytch Connected Apps](https://www.anchorterminal.com/compare/keycard-vs-stytch-connected-apps.md)\n- [Keycard vs WorkOS Pipes and Agents](https://www.anchorterminal.com/compare/keycard-vs-workos-pipes.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Arcade.dev vs Keycard", "url": "" } ], "description": "Arcade.dev has a score of 67 (B) against Keycard's 56.3 (C).
