What is Knock?
Knock adds single-step test runs and retries for failed workflow runs.
Knock is a notification infrastructure platform that spent September and October wiring itself into AI assistants (Claude, ChatGPT/Codex, Cursor) and Stripe Projects. Its latest two releases turn to the workflow debugger: a failed run can now be retried from where it stopped, and a single channel step can be tested in sandbox without running the whole workflow.
What is Prowler?
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.
Knock vs Prowler: editorial side-by-side
Knock
5.0INFRA · APIS
Knock adds single-step test runs and retries for failed workflow runs.
◆ Current state
Knock is a notification infrastructure platform that spent September and October wiring itself into AI assistants (Claude, ChatGPT/Codex, Cursor) and Stripe Projects. Its latest two releases turn to the workflow debugger: a failed run can now be retried from where it stopped, and a single channel step can be tested in sandbox without running the whole workflow.
◆ Where it's heading
With distribution through AI tools in place, Knock is now improving the day-to-day build-and-debug loop for workflows, following the September analytics tab. The pattern points to more operational tooling around runs, not new channels.
◆ Prediction
Expect further debugger and test-runner features, such as bulk retries or replays with edited data, given two debugging releases in three days.
Prowler
6.3INFRA · APIS
Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.
◆ Where it's heading
Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.
◆ Prediction
Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.
