Userback vs Prowler
A side-by-side editorial comparison of Userback and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Userback vs Prowler: at a glance
What is Userback?
Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
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.

Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.
◆ Current state
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
◆ Where it's heading
Sites moves Userback toward running many properties from one account. Copying widget settings and sorting Sites by open feedback are built for agencies with a Site per client. The readable IDs that travel into Jira and other integrations show the same push seen in the 'Sent to Integrations' filter: making Userback the traceable start of a ticket, not a separate inbox.
◆ Prediction
Expect more cross-Site tooling, such as copying integrations or templates between Sites, since the October 28 notes say integrations still have to be set up per Site.
Prowler
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.
