Flomesh Service Mesh (FSM) stands out as a cloud-native service mesh solution renowned for its lightweight design and adaptability, catering to both x86 and ARM architectures. FSM excels in seamlessly managing traffic for deployments while ensuring the security of service-to-service communication through mutual TLS. Moreover, it empowers users to define and enforce finely-tuned access control policies, providing valuable insights into application metrics for effective debugging and service monitoring, thanks to its robust observability features. What sets FSM apart is its effortless integration with external certificate management services through a pluggable interface. Simplifying the onboarding process for applications onto the mesh, FSM achieves this through the automatic sidecar injection of the Pipy proxy. Noteworthy is FSM's support for Multi-cluster Kubernetes, facilitated by the implementation of the MCS-API and support of Kubernetes Gateway API via its own implementation of Kubernetes Gateway API specification. FSM package includes built-in controllers for Ingress/Egress and the Gateway API, along with support for protocols such as MQTT.

High performance, low resources.

Data plane proxy Pipy is developed in C++. It uses an asynchronous network framework; allocated resources are pooled and recycled. Provides high performance with a shallow resource footprint, suitable for large-scale, high-density cloud scenarios and edge scenarios with limited processing power and performance.

High performance, low resources


With ErieCanal, which supports Ingress, Gateway API, and cross-cluster service discovery, it provides Kubernetes intra-cluster + multi-cluster "east-west + north-south" traffic management and service governance capability. It enables cross-cluster interoperability and traffic scheduling to solve the traffic management challenges in multi-cluster use cases.

ARM Ready.

Supports x86, ARM64, Longxin, and RISC-V computing architectures to improve hardware compatibility and meet the needs of diverse computing scenarios.

ARM Ready
Easy to scale

Easy to scale.

The data plane uses a programmable proxy Pipy and a built-in JavaScript engine, which allows customization and extension of the service mesh functionality using JS syntax scripts.
The control plane is based on OSM (Open Service Mesh) developed by Go, and the open design makes it easy to extend the functionality.


Generates comprehensive telemetry data for network traffic within the mesh, providing non-intrusive observability for application containers, including metrics, distributed traces, and logs. Easily customize various metrics and provide multiple log collection and processing methods through the ease of scalability of the data plane.
Visual display of telemetry data is provided through the console.

Multi-protocol Support

Multi-protocol Support.

Pipy natively supports HTTP1, HTTP2/gRPC, TCP, UDP, MQTT, Dubbo, Thrift, and other protocols; the control plane currently supports HTTP1, HTTP2/gRPC, TCP, UDP traffic management, and more protocols can be supported through extensions.

Support for SMI.

SMI (Service Mesh Interface) provides a standard interface to the Kubernetes Service Mesh, a basic set of features for standard Service Mesh scenarios, the flexibility to provide new Service Mesh features, and a space for innovation in the Service Mesh technology ecosystem that is easy to use.

Support for SMI


Provides a powerful console that facilitates managing the Service Mesh and configuring service governance features in addition to rich data presentation.
