Reviewer Notes

Thunkable is fundamentally a UI/UX-first visual development platform optimized for human interaction, not API-driven agent automation. While it has a free tier and OAuth support, there is no published OpenAPI spec, MCP server, or programmatic API documentation that would allow agents to discover capabilities, authenticate, or build applications autonomously. The platform requires interactive UI manipulation and visual block arrangement, making it incompatible with headless agent workflows. Best suited as a tool humans use directly rather than one agents integrate with.
