Alibaba Cloud Service Mesh vs Flomesh Service Mesh

Alibaba Cloud Service Mesh has no write-up on Specifiction yet; its figures are above.

Flomesh Service Mesh (FSM) provides traffic management and service governance for microservices running on Kubernetes. It uses the Flomesh Pipy proxy, which is automatically added as a sidecar to onboarded applications. FSM supports traffic shifting, ingress and egress, and Kubernetes Gateway API capabilities, along with HTTP, TCP, gRPC and MQTT traffic. For service security, it enables mutual TLS and fine-grained access policies. Certificate management can use Tresor, cert-manager or HashiCorp Vault. Documentation marks Prometheus and Grafana integrations as stable and Jaeger distributed tracing as beta; integration guides also cover Dapr and discovery registries such as Consul, Eureka and Nacos. FSM supports x86 and ARM architectures and multi-cluster Kubernetes connectivity through the MCS API, though multicluster is marked alpha. It is open source, free and self-hosted, with Kubernetes and OpenShift listed. Installation requires Kubernetes 1.19 or later; version 1.1 is listed for Kubernetes 1.19 through 1.24.
