What is Kestra?
Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.
Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.
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.
Kestra vs Knock: editorial side-by-side
Kestra
5.0INFRA · APIS
Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.
◆ Current state
Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.
◆ Where it's heading
The visible work is a frontend refactor onto Kestra's own design system, which should show up as filter and table improvements in the 2.1 UI. The feed has no notes on 2.1's orchestration features.
◆ Prediction
Expect 2.1.0 to ship with new filtering in the UI; the entries don't say what else it contains.
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.
