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.
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.

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.

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.
