Reviewer Notes

Payload is well-documented with comprehensive REST/GraphQL APIs and good developer experience, but lacks agent-specific discovery mechanisms like OpenAPI specs, MCP servers, or llms.txt files. Account creation requires manual setup and database configuration—agents cannot self-serve. The self-hosted nature means agents must deploy and manage infrastructure (Docker, database) before use, creating significant friction. API tooling is solid with structured JSON responses and error handling, but self-hosting responsibility limits reliability scoring. Pricing is free to self-host but requires infrastructure costs; no managed SaaS tier for frictionless agent access.
