Better Auth is listed for Auth, Identity workflows. Better Auth is a framework-agnostic authentication library for TypeScript with 50+ plugins, 35+ OAuth providers, and built-in support for organizations, passkeys, 2FA, and agent auth. Ships with MCP server, Claude Code skills, and Cursor rules so AI agents can configure auth. Supports any database via direct drivers or ORM adapters including Drizzle, Prisma, and MongoDB. Consider it when an agent needs this capability through a documented service boundary instead of custom infrastructure maintained inside the application.
In 4agent's task model, the product maps to authentication and secrets. That makes it a candidate for workflows that build and deploy software, communicate with users, automate business workflows, operate production agents.
Integration checklist
- Access: confirm the none authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
- Client support: official or documented clients are listed for typescript.
- Automation: OpenAPI is not currently recorded, MCP is listed as available, and CLI support is listed as available. Confirm each requirement in the provider's current documentation.
- Operations: test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.
