Source-available successor to Ingress NGINX with Gateway API v1.4.0 support and 50+ NGINX annotation compatibility
JANUARY 1, 2026 — Asticou Island LLC today announced the public source-available release of Asticou Ingress Gateway, a high-performance, Kubernetes-native ingress controller built as a modern successor to Ingress NGINX. The project is available under the Elastic License 2.0 (ELv2) with Apache 2.0 for example code and provides a production-ready alternative with full compatibility for 50+ NGINX Ingress annotations.
The Ingress NGINX project, which powers ingress traffic for millions of Kubernetes clusters worldwide, is in maintenance mode with security updates only. Combined with recent CVE-2025-1974 vulnerabilities, enterprises are actively seeking a modern replacement.
Asticou addresses this gap with a purpose-built Java/Netty implementation featuring:
Drop-in compatibility with 50+ Ingress annotations (HTTPRoute routing, session affinity, canary deployments)
Modern Gateway API built on Gateway API v1.4.0 standard
High performance benchmarks comparable to other modern ingress controllers on similar hardware
Zero-downtime reloads for configuration updates without service disruption
Kubernetes-native design with full support for virtual hosting, path-based routing, and TLS termination
Production-ready with comprehensive metrics, health checking, and operational observability
Asticou Ingress Gateway is available immediately under the Elastic License 2.0 (ELv2) with Apache 2.0 for example code. This source-available model provides transparency, auditability, and the ability to review and modify the codebase while supporting the continued development of the project.

Performance Characteristics (RC1)
Asticou's engine uses Java 25 Virtual Threads and Netty with io_uring support (Linux 5.9+). In internal end-to-end benchmarks on like-for-like hardware, the 1.0.0-rc1 build benchmarks comparably to NGINX Ingress and other modern ingress controllers, typically showing small (2–4%) improvements in throughput and latency once warmed up. Actual RPS, latency, and memory usage depend heavily on workload and environment.
Feature Parity
50+ NGINX Ingress annotations supported with full compatibility:
nginx.ingress.kubernetes.io/rate-limit
nginx.ingress.kubernetes.io/rewrite-target
nginx.ingress.kubernetes.io/proxy-buffering
nginx.ingress.kubernetes.io/enable-cors
...and 46 more
