What is Durable Actors?
Durable Actors provides a runtime for building real-time, multi-agent systems where each actor maintains durable state and handles requests serially. It offers TypeScript and Python SDKs with automatic client generation, WebSocket support for live updates, and built-in observability. The system can be self-hosted on Google Cloud via a Helm chart deploying to GKE Sandbox with PostgreSQL, Redis, and GCS buckets. Local development runs on Bun. It's positioned as an open-source replacement for Cloudflare Durable Objects without vendor lock-in or memory limits.
