Architecture

Scale up. Scale down. Never restart.

Synapse Pro is purpose-built for demanding production environments. Its elastic worker architecture automatically adjusts capacity in response to real-time demand — scaling up under load and conserving resources during quieter periods, without ever requiring a server restart.

The result is a homeserver that handles sudden surges — thousands of users logging in simultaneously — with no manual intervention and no degradation in performance.

  • Autoscaling worker architecture responds to demand in real time
  • Horizontal scalability across multiple nodes and data centres
  • Industry-standard Helm-chart deployment on Kubernetes
  • LTS releases every six months, supported for 12 months with Level 3 support

Capabilities

Built for every dimension of scale.

Six engineering pillars that make Synapse Pro the most capable Matrix server available for enterprise and sovereign deployments.

Dynamic Scaling

Worker processes scale up and down automatically in response to real-time load. Traffic spikes — morning login rushes, large broadcast events — are absorbed without manual tuning or restarts.

High Availability

Designed for zero-downtime by default. Redundant failover operates transparently within and across data centres, ensuring your communications platform stays online regardless of individual node failures.

Rust Architecture

Critical server components are written in Rust, unlocking multi-core CPU utilisation and exceptional memory efficiency. Shared data caches reduce RAM overhead significantly — delivering more capacity from the same hardware.

Kubernetes-Native

Full Helm-chart deployment support enables fast, repeatable provisioning on any Kubernetes cluster. Integrates cleanly with existing infrastructure tooling — CI/CD pipelines, monitoring stacks, and secrets management.

High-Density Multi-Tenancy

Run tens of thousands of independent tenant instances on a single cluster. Shared microservices eliminate redundant data duplication, enabling extraordinary density without sacrificing isolation or performance per tenant.

Fleet Management

Operate and manage thousands of deployments from a single control plane. Synapse Pro's architecture is designed for operators managing large portfolios of hosted instances — with resource tracking, policy enforcement, and centralised update management.

Performance

More users. Less hardware. Lower cost.

Synapse Pro's shared microservice architecture fundamentally changes the economics of running a large Matrix deployment. By eliminating redundant processing and pooling resources intelligently, the same infrastructure serves exponentially more users.

For organisations running multi-tenant deployments, the savings compound further. With up to 50 tenant instances per shard, RAM costs can be reduced by up to 90% — without any reduction in per-tenant isolation or performance guarantees.

Deployment models

From a single organisation to thousands.

Synapse Pro's architecture scales from a focused enterprise deployment to a hosted platform serving thousands of independent tenants — without changing the underlying stack.

Large-scale deployments

Enterprise & sovereign deployments

For large organisations running a single deployment at scale. Synapse Pro's dynamic scaling and autoscaling worker architecture means it adapts to your organisation's actual usage — not a worst-case provisioned estimate.

  • Dynamic autoscaling — capacity adjusts without restarts
  • High availability across multiple nodes and data centres
  • Handles sudden load spikes — thousands of concurrent logins
  • Full Kubernetes-native deployment with Helm charts

Multi-tenant platforms

Hosted service providers

For managed service providers and operators running Matrix infrastructure for multiple independent organisations. Synapse Pro's multi-tenancy model shares microservices across tenants, delivering extraordinary resource efficiency at the platform level.

  • Up to 50 tenant instances per shard
  • Shared data caches — eliminate redundant storage across tenants
  • Fleet management tools for thousands of simultaneous deployments
  • Full isolation per tenant — separate data, policies and access controls

FAQ

Common questions.

What makes Synapse Pro different from a standard Matrix homeserver? +
Synapse Pro is the enterprise-grade server at the core of every ESS PRO deployment. It is built in Rust for superior CPU utilisation and memory efficiency, features autoscaling worker architecture, shared data caches that dramatically reduce RAM overhead, and high availability across multiple nodes — capabilities that are not present in standard open-source homeservers. It is also ISO 27001 and CRA compliant, and ships under an enterprise LTS programme with 12-month support windows.
How does the 80% resource saving work? +
The savings come from shared microservices that eliminate redundant data duplication across the deployment, combined with high-density multi-tenancy where resources are pooled intelligently across tenant instances. Synapse Pro's Rust-based components also use shared data caches to dramatically reduce per-instance RAM consumption — giving the same hardware far greater capacity than a conventional homeserver architecture.
What does "high availability by default" mean in practice? +
Every Synapse Pro deployment includes redundant failover mechanisms that operate transparently — no manual intervention required. If a node or worker fails, traffic is automatically redistributed. This applies both within a single deployment and across multiple data centres. Combined with zero-downtime scaling, it means your communications platform continues operating without interruption even during infrastructure events or high-load periods.
Is Synapse Pro compatible with our existing Kubernetes infrastructure? +
Yes. Synapse Pro ships with full Helm-chart support and is designed to deploy cleanly into any standard Kubernetes environment. It integrates with existing CI/CD pipelines, secrets management solutions, and observability stacks. For organisations already running Kubernetes workloads, Synapse Pro slots in without requiring a parallel infrastructure track.
How does LTS and support work? +
Synapse Pro ships on a Long-Term Support release cadence — a new LTS version every six months, each supported for 12 months. This gives enterprise operators a predictable, stable upgrade path with packaged security updates and advisories throughout the support window. Level 3 support covers all functionality issues and bug fixes, with response times prioritised by severity.
