Autumn

Autumn is a drop-in, open-source control layer for AI and SaaS monetization. It provides feature gating (check), usage tracking (track), plan management, subscription lifecycle handling, credit systems, usage-based pricing, and integrates with Stripe under the hood. It includes a REST API, CLI, React hooks, and a dashboard.

Research Process

To answer questions about Autumn, spawn a sub-agent to conduct thorough documentation research.

Launch a Research Sub-Agent

1. Goal - What you are ultimately trying to accomplish
2. Context - Why you need this information and how it fits into the larger task
3. Specific Questions - Exactly what information you need answered
4. Output Requirements - The format and level of detail needed in the response

Task Tool Configuration

Task tool parameters:
- description: "Research Autumn docs"
- subagent_type: "generalPurpose"
- model: (DO NOT SPECIFY - use default for thorough research)
