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 Buildkite?
Buildkite widens its API surface for agent-driven CI debugging and observability
Buildkite's recent releases cluster around one theme: exposing more of the CI runtime through APIs. Richer REST job and agent objects, per-job performance metrics, and MCP server tooling all aim at automated and agent-driven consumers, alongside a security fix and an infrastructure notice.

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.
Buildkite

Buildkite widens its API surface for agent-driven CI debugging and observability
◆ Current state
Buildkite's recent releases cluster around one theme: exposing more of the CI runtime through APIs. Richer REST job and agent objects, per-job performance metrics, and MCP server tooling all aim at automated and agent-driven consumers, alongside a security fix and an infrastructure notice.
◆ Where it's heading
The platform is being reshaped for programmatic and agentic use — surfacing signal_reason and runner context so automation can tell infrastructure failures from code failures, adding job-level CPU/memory/disk metrics, and splitting jobs from builds for large-matrix querying. The MCP investment (elsewhere in the feed) is the same bet from another angle.
◆ Prediction
Expect the REST and GraphQL surfaces to keep expanding toward machine consumers, with the MCP server becoming the primary interface for automated build triage.
