What is Knock?
Knock is building an agent-and-environments layer on top of its notifications infrastructure
Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.
What is Render?
Render keeps hardening its PaaS: faster builds, deeper operability, agent-friendly tooling
Render is a managed application platform (a Heroku-style PaaS) shipping a steady stream of platform refinements rather than headline features. The last ten releases cluster around build performance (Node and Python median build times down 25–27%), operability (SSH into ephemeral instances, changing a service's backing repo or image from the dashboard), networking (dedicated outbound IPs), and runtime version automation. A quieter but consistent thread is agent-oriented tooling — CLI service creation and the Workflows beta for durable background tasks.

Knock

Knock is building an agent-and-environments layer on top of its notifications infrastructure
◆ Current state
Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.
◆ Where it's heading
Knock is moving from a notifications API toward an agent-operable platform with environment-promotion workflows — audiences, layouts, and inputs all becoming versioned, previewable artifacts drivable from dashboard, CLI, or agent. Expect more agent-triggerable surface area.
◆ Prediction
Likely more agent-driven authoring (additional data sources, agent skills) and continued environment/versioning tooling; the Slack agent and CLI/agent build paths point to deeper automation of notification ops.

Render keeps hardening its PaaS: faster builds, deeper operability, agent-friendly tooling
◆ Current state
Render is a managed application platform (a Heroku-style PaaS) shipping a steady stream of platform refinements rather than headline features. The last ten releases cluster around build performance (Node and Python median build times down 25–27%), operability (SSH into ephemeral instances, changing a service's backing repo or image from the dashboard), networking (dedicated outbound IPs), and runtime version automation. A quieter but consistent thread is agent-oriented tooling — CLI service creation and the Workflows beta for durable background tasks.
◆ Where it's heading
The direction is incremental hardening: making the platform faster, more debuggable, and more self-serve from both the dashboard and CLI. Moving operations that previously required the API into the dashboard, and adding ephemeral SSH, point to a focus on day-two operations for teams already on the platform. The agent and durable-workflow investments hint at positioning Render as a runtime for automated and long-running backend processes.
◆ Prediction
Expect continued build-time and runtime-automation work across more languages, plus further migration of API-only operations into the dashboard and CLI as Render rounds out its self-serve operability story.
