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 Payload CMS?
Payload v4 beta 3 adds Next.js cache components and moves TanStack Start to React Flight.
Payload 4.0 is on its fourth beta. beta.3 adds support for Next.js cache components, with the admin rendered at request time, and switches the TanStack Start adapter to React Flight for RSC responses, a breaking change for that adapter. The rest is fixes: per-locale validation when writing all locales, live-preview and bulk-upload UI bugs, and a Drizzle locale index tweak. The beta.0 bundle of admin redesign, TanStack Start support and the rewritten MCP server remains the release's core.
Knock vs Payload CMS: 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.
Payload CMS
6.3INFRA · APIS
Payload v4 beta 3 adds Next.js cache components and moves TanStack Start to React Flight.
◆ Current state
Payload 4.0 is on its fourth beta. beta.3 adds support for Next.js cache components, with the admin rendered at request time, and switches the TanStack Start adapter to React Flight for RSC responses, a breaking change for that adapter. The rest is fixes: per-locale validation when writing all locales, live-preview and bulk-upload UI bugs, and a Drizzle locale index tweak. The beta.0 bundle of admin redesign, TanStack Start support and the rewritten MCP server remains the release's core.
◆ Where it's heading
The betas are converging on two framework adapters with comparable rendering models: Next.js gains cache-components support while TanStack Start moves onto React Flight. Breaking changes are now confined to the newer adapter, and most of each beta is fixes and repo tooling, which points toward a stable 4.0.
◆ Prediction
Expect further weekly betas with adapter fixes and migration docs before 4.0 stable. The entries still give no stable date, and further TanStack Start breaking changes remain possible.
