Skipper vs Contour
A side-by-side editorial comparison of Skipper and Contour — release velocity, themes, recent moves, and the top alternatives to consider.

Skipper vs Contour: at a glance
What is Skipper?
One pull request per version tag, and most of them are dependency bumps.
Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.
What is Contour?
Three supported branches, patched in lockstep within the same minute.
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.

Skipper
5.0INFRA · APIS
One pull request per version tag, and most of them are dependency bumps.
◆ Current state
Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.
◆ Where it's heading
The visible work is maintenance of an already-stable proxy rather than feature development. What the test changes hint at is where the correctness concerns sit: an OPA policy test updated to explicitly deny truncated request bodies, because oversized JSON cannot be fully parsed and a policy that ignores input.truncated_body can be bypassed. That is authorization-under-load hardening, and it is the most interesting thing in the window even though it landed as a test.
◆ Prediction
The per-PR tagging rhythm will continue producing several versions a week regardless of change size. Readers tracking this product should expect the meaningful changes to be a small minority of the tags.
Contour
0.0INFRA · APIS
Three supported branches, patched in lockstep within the same minute.
◆ Current state
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.
◆ Where it's heading
This is a proxy whose release cadence is governed by its data plane rather than its own feature work. Envoy security releases set the schedule, and Contour's job is to bump, verify compatibility and ship across every supported branch simultaneously. The changes that do originate in Contour are operational sharp edges found in production: an HTTPProxy CRD schema wrongly marking a status error field as required, which broke load balancer status updates, and shutdown-manager being CPU-throttled at a 50m limit.
◆ Prediction
The next release will almost certainly be another simultaneous three-branch batch triggered by an Envoy security bump, since both batches in this window followed exactly that pattern.
