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 Velociraptor?
Velociraptor's recent releases are mostly about patching CVEs.
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.
Knock vs Velociraptor: 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.
Velociraptor
0.0INFRA · APIS
Velociraptor's recent releases are mostly about patching CVEs.
◆ Current state
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.
◆ Where it's heading
Since June the project has been in security mode, fixing CVEs on the current line and backporting to the previous one. Feature work shows up as new artifacts, here an Azure Monitor export, which keeps Velociraptor feeding results into the logging tools teams already use.
◆ Prediction
Expect further 0.77 patch releases and possibly another backport if new CVEs are published; the timing of a 0.78 feature release is not signaled here.
