Soketi
Soketi is an open-source, high-performance WebSocket server designed for developers who need real-time pub/sub messaging at scale. It implements the Pusher protocol, enabling teams to self-host real-time features such as notifications, collaboration, and dashboards without vendor lock-in. Soketi is well-suited for those seeking a cost-effective and customizable alternative to hosted solutions like Pusher, offering flexibility across deployment environments from local development to large production clusters.
With compatibility for Pusher client libraries and a modern, Node.js-based setup, Soketi can be quickly integrated into existing infrastructures. Its focus on efficient resource use and prominent support for industry tools (like Prometheus and Redis) makes it appealing for both startups and established engineering teams looking to optimize spending and maintain ownership of their real-time data systems.
Use Cases
- Engineering teams requiring real-time features for chat, notifications, IoT dashboards, or live collaboration tools.
- Organizations migrating from Pusher seeking to reduce costs or gain more control over data hosting.
- Developers building SaaS platforms, custom applications, or internal tools with scalable pub/sub messaging requirements.
- Companies prioritizing cost efficiency by leveraging self-hosted infrastructure instead of SaaS billing models.
Strengths
- High Performance WebSocket Server: Handles thousands of concurrent connections efficiently, suitable for large-scale real-time apps.
- Pusher Protocol v7 Compatibility: Integrates seamlessly with existing Pusher client libraries for quick migration.
- Open Source and Self-Hosting: MIT license enables full auditability and custom deployments on any infrastructure.
- Cost-Effective Scaling: Operates at low hardware requirements, reducing operational and cloud costs.
- Flexible Deployment: Supports Docker, monolith, and clustered setups to fit diverse workflows.
- Built-in Metrics: Exports Prometheus-compatible metrics for observability and production monitoring.
- Multiple Storage Integrations: Connects with Redis, DynamoDB, PostgreSQL, or static arrays for scaling state management.
- Cluster Support via Redis: Horizontal scaling for mission-critical, high-traffic applications.
- Low Resource Footprint: Typical setups require less than 1GB RAM and 1 CPU.
Limitations
- Missing advanced analytics and comprehensive dashboards found in mature SaaS solutions (e.g., Pusher).
- Large-scale deployments demand correct Redis clustering and infrastructure expertise for optimal reliability.
- Smaller community and evolving documentation may make troubleshooting and onboarding harder for new users.
Final Thoughts
Soketi stands out as a robust alternative for teams aiming to self-host and control their real-time WebSocket infrastructure while benefiting from full Pusher compatibility and open-source flexibility. It particularly excels for developers who value cost efficiency, data privacy, and integration with modern monitoring stacks. However, teams should anticipate investing in setup, monitoring, and (for large deployments) clustering expertise. Organizations seeking advanced analytics or turnkey enterprise support may find greater value in managed SaaS offerings.
For teams experienced with Pusher or Node.js, Soketi presents a smooth transition toward self-hosted, scalable real-time messaging—provided they are prepared to manage the operations in-house.
