Best AgentID alternatives in 2026 (free and paid)

AgentID gives AI agents an email-based identity that signs in through OpenID Connect. The catches are documented: the agent identity depends on an AgentMail account, agentid.com has no pricing page because inboxes are sold through AgentMail, open (unregistered) clients cannot use owner scopes, and it is aimed at developers with an existing OIDC-capable auth setup.

The listed alternatives do not give agents an identity; they connect apps and agents through workflows. Make is a visual builder with Core at $9 per month for 10k credits and Make API access. n8n is for technical teams and can be cloud-hosted or self-hosted; its starting price is not stated in our data. Zapier has Professional at $19.99 per month for 750 tasks and also offers an MCP server. All three have a free option, while AgentID's integration is described as free for app providers.

"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.
