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 Sonarr?
Sonarr 5.0 builds add Trakt Smart Lists, OIDC Remember Me and more accessibility fixes.
Sonarr is publishing 5.0 test builds every few days. Recent ones added a Trakt Smart List import, an option to pass seed time to qBittorrent as an inactive-seeding limit, Remember Me for OIDC login and lower-memory media info migration. Accessibility work continues, with screen-reader feedback for form errors, named icon-only controls and an accessible Calendar.
Knock vs Sonarr: 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.
Sonarr
5.0INFRA · APIS
Sonarr 5.0 builds add Trakt Smart Lists, OIDC Remember Me and more accessibility fixes.
◆ Current state
Sonarr is publishing 5.0 test builds every few days. Recent ones added a Trakt Smart List import, an option to pass seed time to qBittorrent as an inactive-seeding limit, Remember Me for OIDC login and lower-memory media info migration. Accessibility work continues, with screen-reader feedback for form errors, named icon-only controls and an accessible Calendar.
◆ Where it's heading
5.0 is in a polish phase: each build mixes small features from contributors with accessibility and UI fixes, after the earlier builds removed Basic Auth and tightened file safety. The pace suggests the team is converging on a stable 5.0.
◆ Prediction
Expect more accessibility and migration fixes before 5.0 reaches the stable channel; new large features look unlikely this late.
