Review and moderation, your way.
Coop is the open source review and moderation tool from ROOST that provides a comprehensive solution for online safety:
- Review Console: Human review interface for complex moderation decisions
- Content Processing: Support for posts, comments, media, and custom content types
- Analytics: Detailed insights into moderation effectiveness and trends
- Rules Engine: Automated content evaluation against customizable policies
- API Integration: Simple REST and GraphQL APIs for seamless platform integration
Coop is for anyone who needs to make online safety decisions: platforms of all sizes, solo developers, and community teams without dedicated trust and safety staff.
Most moderation tooling is proprietary and priced for platforms that can already afford it. Coop is free and open source so your data stays within your infrastructure, and you can customize it for your community's needs.
A few things that shape how we build it:
- The platform owns its policy. Coop is the plumbing to implement and enforce your own rules.
- Child safety is a prioritized workflow. As the first free end-to-end online child safety system, it is one of the reasons Coop exists.
- The codebase is auditable, with no hidden logic and no vendor lock-in.
