Overview
AnyCable is a real-time WebSocket server that runs alongside an application's backend to handle long-lived connections at scale. It was created by Vladimir Dementyev and has been developed as open source by Evil Martians since 2017, with production use at more than 50 companies.
Key Features
AnyCable provides delivery guarantees, automatically recovering missed messages after network interruptions and preserving connections through application deployments. It handles over 10,000 concurrent connections per server with low memory overhead, and integrates with Rails (including native Hotwire/Turbo support), Laravel, Node.js, and Python, or any backend via HTTP API. It uses an embedded NATS pub/sub layer, requiring no additional infrastructure beyond the HTTP API.
Pricing Overview
The open-source edition is free and includes Hotwire support, JWT authentication, and Prometheus/StatsD instrumentation. A Pro plan costs $1,490 per year (with a two-month free trial) and adds unlimited instances, cluster-mode consistency, slow-drain shutdown, and binary compression. A managed hosted offering is also in development, and consulting for setup, deployment, and load testing is billed at $200 per hour.
