Discord Open Sources Osprey Safety Rules Engine Processing 2.3 Million Rules per Second

Discord open-sourced Osprey, a safety rules engine processing 400 million daily actions and 2.3 million rules per second. Osprey uses a polyglot architecture: a Rust coordinator manages traffic, while stateless Python workers execute logic using a Python-based domain-specific language called SML. This design allows trust and safety teams to deploy real-time threat mitigations at high scale.
