Caddy vs Prowler: 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 Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

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.

Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
