Caddy vs CircleCI: at a glance
What is Caddy?
Caddy 2.11's betas add ECH key rotation and a release process without its founder.
Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.
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.

Caddy 2.11's betas add ECH key rotation and a release process without its founder.
◆ Current state
Caddy's tracked entries are the two 2.11 betas from December 2025 and January 2026. Beta 1 was the first release cut by the maintainer team's automated process without the original author, and brought time-based log rolling, argon2id basic auth and named socket activation. Beta 2 added ECH key rotation, multiple intermediates in PKI signing chains and a fix for the ZeroSSL issuer.
◆ Where it's heading
Caddy is investing in privacy-preserving TLS through Encrypted ClientHello, and in project continuity through a team-run release pipeline. The rest of the betas are edge-case fixes, consistent with a mature server polishing details.
◆ Prediction
The beta notes point to a 2.11 stable release; no newer entries are tracked, so its timing isn't visible here.
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.
