What is Knock?

Knock keeps widening from a notifications API into an agent-driven engagement platform

Knock remains a developer-first notifications infrastructure product, but recent releases push past send-a-message plumbing. The last month added warehouse sync for delivery and engagement events, a hosted end-user preference center, dashboard MFA, and faster workflow testing. Data now moves both into Knock (Shopify) and back out to the warehouse.

What is SavvyCal?

SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.

SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.

Knock keeps widening from a notifications API into an agent-driven engagement platform

◆ Current state

Knock remains a developer-first notifications infrastructure product, but recent releases push past send-a-message plumbing. The last month added warehouse sync for delivery and engagement events, a hosted end-user preference center, dashboard MFA, and faster workflow testing. Data now moves both into Knock (Shopify) and back out to the warehouse.

◆ Where it's heading

Two arcs stand out: an agentic control surface — a Slack agent that creates and schedules resources, plus dashboard/CLI/agent parity for building audiences — and a maturing enterprise posture via MFA, the preference center, and warehouse analytics. Knock is positioning as a system of record for customer engagement, not just a delivery layer.

◆ Prediction

Expect the agent surface to deepen so more resources are manageable conversationally, and more data connectors after Shopify, given the warehouse-sync and dynamic-audiences direction.

SavvyCal keeps polishing scheduling ergonomics on a slow, steady cadence.

◆ Current state

SavvyCal is a scheduling tool competing on booking-experience quality. Its changelog moves at a measured pace — roughly one release a month — and the recent run is a series of contained refinements: duplicating workflows, locking links against last-minute changes, per-event buffer control, multi-language booking pages, and improvements to booking on behalf of others.

◆ Where it's heading

The through-line is control and convenience for the host and for assistants who schedule for others: workflow reuse, guardrails on rescheduling, richer contact records, and localized booking pages. Nothing here shifts the product's category; it is deliberate incrementalism aimed at making the existing scheduling surface more flexible and reliable.

◆ Prediction

Expect more of the same — small, self-contained booking and workflow refinements on a monthly rhythm — absent any signal of a larger platform or AI move in these entries.
