CircleCI vs Skipper
A side-by-side editorial comparison of CircleCI and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
CircleCI vs Skipper: at a glance
What is CircleCI?
CircleCI's SSH reruns now open from the browser, through one trusted address.
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.
What is Skipper?
Skipper fixes a 304 path that could drop active routes after an interrupted download.
Skipper, Zalando's HTTP router and Kubernetes ingress, tagged a dozen releases in early November, most of them security fixes in how filters see the request path. v0.28.72 and v0.28.74 made the oidcClaimsQuery and OPA filters check the normalized path. v0.28.76 on November 12 fixes a route-loading bug: an interrupted route download could save an incomplete cache with a new ETag, and a 304 reply then removed routes that were active.

CircleCI

CircleCI's SSH reruns now open from the browser, through one trusted address.
◆ Current state
CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.
◆ Where it's heading
CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.
◆ Prediction
Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
Skipper
5.0INFRA · APIS
Skipper fixes a 304 path that could drop active routes after an interrupted download.
◆ Current state
Skipper, Zalando's HTTP router and Kubernetes ingress, tagged a dozen releases in early November, most of them security fixes in how filters see the request path. v0.28.72 and v0.28.74 made the oidcClaimsQuery and OPA filters check the normalized path. v0.28.76 on November 12 fixes a route-loading bug: an interrupted route download could save an incomplete cache with a new ETag, and a 304 reply then removed routes that were active.
◆ Where it's heading
After the auth-filter fixes, the work has moved to the route data client, where a partial download combined with ETag caching could take routes out of service. The project is in a hardening phase across both request handling and configuration loading.
◆ Prediction
Expect further v0.28.x tags fixing edge cases in route loading and filters; the entries show no feature work queued.
