Coop
ROOSTAn open, self-hosted review and moderation console from ROOST. It provides review queues, routing, automated enforcement rules, analytics, and REST/GraphQL integrations, with child-safety workflows (HMA hash matching, NCMEC reporting) and integrations with the OpenAI Moderation and Google Content Safety APIs. Trust & Safety operational tooling that orchestrates AI safety signals rather than an AI guardrail model.

README says 'Coop is free and open source so your data stays within your infrastructure', that the codebase is 'auditable, with no hidden logic and no vendor lock-in', and runs it 'with a single command using Docker Compose'. No paid tier, enterprise directory or license key on the page.
Adoption
3 medium confidenceGitHub breadth is modest, but Coop is deployed across varied production environments. Coop is the open-sourced productization of the acquired Cove codebase, and former Cove clients carried over as users. Notion is publicly committed and is likely Coop's largest production deployment to date. The v1.0 announcement adds named production feedback from Kyodo (a community-first messaging platform with over 150 million messages sent; CEO testimonial) and an unnamed large-scale adopter (tens of millions of users, ~95% cut in safety-tooling costs), plus NCMEC as a CSAM-reporting integration partner. Adoption rests on named production deployments rather than community breadth, mirroring sibling Osprey. The repo carries none of this: its 'Used in production' list is empty and it shows 77 stars, so the Notion/Kyodo/Musubi names rest on the announcements alone, and Musubi appears on ROOST's Coop page as a hosted provider rather than an adopter. The level and the niche reach stand on the named deployments.
