One source of truth for your protocols.
Protocol Registry is a managed schema registry for game networking. Define your message formats once, version them with confidence, and distribute them automatically to every client and server.
Schema-first protocol design
Define packet schemas in a simple IDL. Protocol Registry compiles them into typed client libraries for TypeScript, C#, C++, and Rust.
Semantic versioning
Every schema change is versioned. Breaking changes are flagged automatically and blocked from publishing until all dependants have migrated.
Live schema distribution
Push protocol updates to all connected clients and servers instantly. No re-deploy required for backward-compatible changes.
Multi-game isolation
Each game or environment gets its own registry namespace. Protocols never bleed between projects, and access is controlled per namespace.
Auto-generated SDK
Every time you publish a schema, typed serialisers and deserialisers are generated and pushed to your package registry automatically.
Validation at the edge
Incoming packets are validated against the registered schema at the Relay layer before they ever reach your game server, blocking malformed or malicious messages.
Schema diffing and changelogs
Every version diff is stored and queryable. Review what changed between any two versions, who published it, and when.
Global replication
Registry data is replicated across all edge regions so schema lookups are fast regardless of where your servers are running.
Networking
