We're excited to announce the general availability of CometChat On-Premise Deployment, giving you complete control over your real-time messaging infrastructure. This update enables you to deploy CometChat within your own infrastructure, whether on private cloud, data centers, or air-gapped environments, with full data sovereignty and enterprise-grade performance.
Instead of relying on our managed cloud service, you can now run the entire CometChat platform on your own servers. This makes it possible to meet strict compliance requirements, control data residency, and achieve predictable costs at scale while maintaining the same feature-rich messaging experience your users expect.
Why does this matter to me, as a developer?
Real-time messaging infrastructure is critical, but it's not one-size-fits-all. Many organizations face regulatory requirements, data sovereignty mandates, or security policies that make cloud-hosted solutions challenging or impossible to adopt.
With CometChat On-Premise, you can:
Meet compliance requirements by keeping all user data within your controlled infrastructure, essential for GDPR, HIPAA, SOC 2, and industry-specific regulations.
Eliminate per-user pricing unpredictability with fixed infrastructure costs, making budgeting and scaling more transparent as your application grows.
Deploy in air-gapped or restricted environments where external cloud services aren't permitted, such as government, defense, or highly regulated industries.
Achieve consistent sub-100ms latency with dedicated resources and optimized data locality, rather than competing for shared cloud resources.
Integrate with existing security infrastructure including private networks, custom authentication systems, and internal monitoring tools.
Integrate with existing security infrastructure including private networks, custom authentication systems, and internal monitoring tools.
This gives you the flexibility to design communication experiences that align with your organization's security, compliance, and operational requirements.
Key features and capabilities
Multiple deployment options
Choose between Docker Swarm (recommended for 10k-200k monthly active users) or Kubernetes (for enterprise and multi-region deployments). Both options provide production-grade reliability with different operational complexity profiles.
Complete feature parity
All CometChat features work identically in on-premise deployments: 1:1 and group messaging, typing indicators, read receipts, push notifications, webhooks, content moderation, and our complete REST API suite.
Polyglot persistence architecture
The platform uses purpose-built data stores optimized for specific workloads: TiDB for distributed SQL with ACID guarantees, MongoDB for flexible document storage, Redis for sub-millisecond caching, and Kafka for guaranteed event delivery.
Enterprise monitoring and observability
Built-in Prometheus, Grafana, and Loki stack provides real-time operational dashboards, SLA monitoring, and comprehensive audit trails, giving you complete visibility into system behavior.
Interesting tech details
This deployment architecture builds on cloud-native principles and battle-tested open-source technologies, designed to handle enterprise workloads from day one.
The platform employs a microservices architecture where:
Stateless services enable linear scaling by adding compute resources without data migration or architectural changes.
Apache Kafka serves as the central event backbone, providing guaranteed message ordering, fault-tolerant persistence, and effectively-once delivery semantics.
WebSocket gateway maintains persistent connections with automatic reconnection handling and session recovery for uninterrupted real-time experiences.
Encrypted overlay networking isolates backend services with service-to-service communication secured by default within the Docker Swarm cluster.
This approach ensures your messaging infrastructure remains reliable, predictable, and scalable as your application grows from thousands to hundreds of thousands of monthly active users.
