!!! info "Last updated" This document and the table below were last updated on 2026-02-23. Implementation statuses, GitHub stars, and contributor counts change frequently — verify against the official implementations page for the latest status.

Requirements

For inclusion in this documentation, Gateway API implementations must meet the following criteria:

  1. Open Source: The implementation must be open source software
  2. Official Listing: Must be listed on the official Gateway API implementations page

Available Open Source Implementations

Implementation Status Type GitHub Stars Contributors Description

WSO2 APK 🔴 Stale Other 166 30+ Open source API management solution
ingate ⚠️ Retiring Other 685 Multiple Kubernetes SIG Network reference impl — retiring early 2026

Status Legend: ✅ GA = Generally Available, fully conformant | ✅ Conformant = Passes full conformance tests (no GA label) | ✅ SM = Service mesh conformance only | 🟡 Partial = Partially conformant (passes some but not all conformance tests) | 🔴 Stale = No recent conformance reports submitted to the official registry | ⚠️ Retiring = Deprecated / being retired

Notes:

  • ingate was a migration path from NGINX Ingress Controller to Gateway API — SIG Network recommends migrating away immediately
  • GitHub Stars are approximate and were last checked on 2026-02-23
  • Status is based on the official conformance registry
