What is Knock?
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
What is Retool?
Retool is fencing in its app-building agent — plan mode above, row-level data policies below.
Releases arrive several times a week and split cleanly. One line extends the app-building agent: standing building context, multiple threads per branch, and now a plan mode that shows intended changes before they land. The other tightens administration: PostgreSQL access policies in public beta, BYOK token accounting, an admin onboarding hub, plus self-hosted release and migration notices.

Knock

Knock is hardening for enterprise buyers while its agent takes over the analysis work.
◆ Current state
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.
◆ Where it's heading
Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
◆ Prediction
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
Retool
5.0INFRA · APIS
Retool is fencing in its app-building agent — plan mode above, row-level data policies below.
◆ Current state
Releases arrive several times a week and split cleanly. One line extends the app-building agent: standing building context, multiple threads per branch, and now a plan mode that shows intended changes before they land. The other tightens administration: PostgreSQL access policies in public beta, BYOK token accounting, an admin onboarding hub, plus self-hosted release and migration notices.
◆ Where it's heading
The two lines are the same bet. Retool is making agent-built apps acceptable to organizations that cannot let a generated app decide what data it reads, so every agent capability is paired with a constraint — instructions the agent must follow, a plan the reviewer sees, and access policies enforced at the resource rather than in app code. The self-hosted channel keeps pace, which matters for exactly the buyers those controls target.
◆ Prediction
Expect access policies to extend past PostgreSQL to other resource types as they leave beta, and further review or approval steps around the app-building agent.
