OctoPrint vs Prowler: at a glance
What is OctoPrint?
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
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.

OctoPrint
5.0INFRA · APIS
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
◆ Current state
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
◆ Where it's heading
The 2.0 line is in a long stabilisation, with each candidate fixing regressions and asking testers to cover the new connectors. The thin notes on rc6 and rc7 suggest the remaining changes are small.
◆ Prediction
A 2.0.0 final is likely within a few candidates; the exact date is unclear from the entries.

7.5INFRA · APIS
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.
