What is Knock?
Knock is treating notification config like code — branches, tests, and now event-driven waits.
Knock has spent the last two months building the tooling a team needs to manage notification logic as a codebase rather than a settings page: branches with rebasing, sandbox test runs, schema management, tags and saved views. Alongside that it widened what feeds a workflow (Clay tables, warehouse sync) and closed out dashboard security with MFA and passkeys. The delivery engine itself is settled; the surface being built is authoring and governance.
What is Retool?
Retool is fitting its app-building agent into a real git workflow, not around it.
The changelog is a steady stream of app-builder refinements centred on the building agent: multiple agent conversations per branch, checkout of branches created outside Retool, clarifying questions when a request is ambiguous, and support for the newest Claude and GPT model families. Alongside that sits operational housekeeping — a one-time permissions database migration required for self-hosted 4.31 and later, and the sunset of Microsoft SQL integration versions 1.0 and 2.0.

◆ Current state
Knock has spent the last two months building the tooling a team needs to manage notification logic as a codebase rather than a settings page: branches with rebasing, sandbox test runs, schema management, tags and saved views. Alongside that it widened what feeds a workflow (Clay tables, warehouse sync) and closed out dashboard security with MFA and passkeys. The delivery engine itself is settled; the surface being built is authoring and governance.
◆ Where it's heading
Two arcs are running in parallel. The first treats notification config as software — versioned branches, rebasing onto main, tests that run without delivering — which is what a large team with many workflows needs before it will move messaging off in-house code. The second expands the workflow from a linear send into a durable process that can wait, branch, and pull data from outside the product. The newest entry is where those meet.
◆ Prediction
With a wait primitive in place, the next additions are likely more control-flow around it — timeouts, escalation paths, cancellation — plus additional data-source connectors following the Clay pattern.
Retool
6.3INFRA · APIS
Retool is fitting its app-building agent into a real git workflow, not around it.
◆ Current state
The changelog is a steady stream of app-builder refinements centred on the building agent: multiple agent conversations per branch, checkout of branches created outside Retool, clarifying questions when a request is ambiguous, and support for the newest Claude and GPT model families. Alongside that sits operational housekeeping — a one-time permissions database migration required for self-hosted 4.31 and later, and the sunset of Microsoft SQL integration versions 1.0 and 2.0.
◆ Where it's heading
The agent is being fitted into the development workflow teams already have rather than replacing it. Per-branch threads and external branch checkout mean agent work is versioned the way engineers expect, while clarifying questions attack the rework loop that makes generated apps unusable. On the self-hosted side, a mandatory migration and integration sunsets show a platform tightening its supported surface as it grows.
◆ Prediction
The branch-and-thread work points toward review and merge flows for agent-authored changes, since versioning is now in place but nothing shown covers reconciling parallel threads on the same branch.
