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 SigNoz?

SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.

SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.

Knock vs SigNoz: editorial side-by-side

K
Knock
INFRA · APIS
5.0

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.

5.0

SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.

◆ Current state

SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.

◆ Where it's heading

SigNoz is retiring its v1 alerting API in stages, history first and rules next, while widening where alerts go (Jira, incident.io, now Telegram) and what it ingests. The August plugin for AI coding agents remains its main directional bet; recent weeks are platform cleanup around it.

◆ Prediction

Expect weekly reminders until November 11, then a release that removes v1 rules. Further alert channels and cloud-integration log sources are the likely feature follow-ups.
