FluxGate: Open-Source API Gateway for Microservices
Route, secure, and scale your Kubernetes workloads with zero configuration overhead. Built for teams that demand sub-millisecond latency and transparent infrastructure.
kubectl apply -f fluxgate-crds.yaml
fluxctl init --cluster prod-us-east-1
✓ Control plane initialized
✓ eBPF programs compiled
✓ Listening on :8080
Deployed Across 12,000+ Production Clusters
From fintech platforms to global SaaS providers, FluxGate handles over 80 billion requests daily with a 99.99% uptime SLA.
80B+ Requests/Day
Processed across global edge nodes without memory leaks or GC pauses.
99.99% Uptime
Validated by independent audits at Stripe, Datadog, and HashiCorp.
Open Source (MIT)
Fully transparent codebase with 4.2k GitHub stars and active maintainer support.
Kubernetes-Native Traffic Management
FluxGate compiles your routing policies into eBPF programs, bypassing traditional userspace bottlenecks while maintaining full compatibility with Service Mesh standards.
Dynamic Route Compilation
Update routing tables in under 2ms without restarting pods or reloading sidecar containers.
Zero-Trust mTLS
Automatically rotates certificates and enforces mutual TLS across all service-to-service communication.
Rate Limiting & Circuit Breaking
Token bucket algorithms with sliding window counters prevent cascade failures during traffic spikes.
Observability Hooks
Native OpenTelemetry export with structured logging, Prometheus metrics, and distributed tracing.
Benchmark: FluxGate vs. Industry Standards
Independent load testing conducted by CloudNative Labs on AWS c6gn.2xlarge instances using wrk2 with 10,000 concurrent connections.
FluxGate delivered 4.2 million requests per second with a p99 latency of 1.8ms, outperforming NGINX Ingress Controller by 340% and Envoy by 210% under identical memory constraints (512MB limit). CPU utilization remained flat at 12% even during sustained peak loads.
Built for Scale, Trusted by Practitioners
"We replaced our legacy Envoy fleet with FluxGate and cut our infrastructure spend by 40%. The eBPF compilation model eliminated our sidecar overhead entirely, and the declarative YAML configuration fits perfectly into our GitOps workflow."
— Elena Rostova, Principal Platform Engineer at NovaPay
Common Deployment Queries
Does FluxGate require a service mesh?
No. FluxGate operates independently or alongside Istio/Linkerd. It compiles routing logic directly into the kernel via eBPF, removing the need for intercepting containers.
How does configuration hot-reloading work?
Changes are validated against our CRD schema, compiled to bytecode, and injected into active workers without dropping a single packet or triggering a rolling update.
Is the commercial support tier required?
FluxGate Core is fully open-source under the MIT license. Commercial support offers SLA-backed incident response, custom plugin development, and dedicated architecture reviews.
Start Routing at Line Speed
