Quay vs Gloo Gateway
A side-by-side editorial comparison of Quay and Gloo Gateway — release velocity, themes, recent moves, and the top alternatives to consider.
Quay vs Gloo Gateway: at a glance
What is Quay?
The public release feed is pure CVE backporting across two frozen branches.
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
What is Gloo Gateway?
One status-churn fix, shipped to four maintenance branches inside forty minutes.
Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.

The public release feed is pure CVE backporting across two frozen branches.
◆ Current state
Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.
◆ Where it's heading
This is what a supported enterprise registry looks like from the outside: two older branches on life support for customers who have not moved, with feature development happening somewhere the feed does not see. The pattern is machine-driven — cherry-pick robots, changelog bump bots, Renovate-style dependency updates — with human authorship visible mainly on the security fixes. Nothing here indicates what the current development branch is doing.
◆ Prediction
Expect the 3.10 and 3.12 branches to keep receiving paired dependency CVE backports on the same cadence until their support windows close. Any read on Quay's product direction needs a source other than this feed.
Gloo Gateway
5.0INFRA · APIS
One status-churn fix, shipped to four maintenance branches inside forty minutes.
◆ Current state
Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.
◆ Where it's heading
The recurring theme is translation correctness under Kubernetes Gateway API — specifically, bugs where the translator's internal state does not behave the way its callers assume. The report-churn fix found equality checks comparing maps of pointer values, so identical output registered as changed on every recompute. The delegateOptions fix in beta11 found RouteOptions assigned by reference from the snapshot, so merging parent Virtual Service options mutated shared protos and contaminated every other route for the rest of the cycle. Both ship with the same instinct for caution: the second one is gated behind GLOO_ISOLATE_DELEGATE_ROUTE_OPTIONS so operators can revert.
◆ Prediction
The 1.22 beta line will keep collecting Gateway API translation fixes ahead of a stable release, and each one that matters will be backported across all four maintenance branches on the same day, as this window shows twice.
