What is Knock?
Knock pushes an AI agent over its notification stack, from CLI to Slack.
Knock is a developer-first notifications platform, and its recent releases split between hardening the core (MFA, test-runner sandbox mode) and pushing an agent-driven control layer over notification workflows. Teams can now build, trigger, and manage engagement resources from an AI agent — in the dashboard, CLI, or Slack — rather than only through code.
What is Expo?
Expo is running its SDK and EAS release engine at a fast, steady clip.
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.
Knock vs Expo: editorial side-by-side
Knock
6.3INFRA · APIS
Knock pushes an AI agent over its notification stack, from CLI to Slack.
◆ Current state
Knock is a developer-first notifications platform, and its recent releases split between hardening the core (MFA, test-runner sandbox mode) and pushing an agent-driven control layer over notification workflows. Teams can now build, trigger, and manage engagement resources from an AI agent — in the dashboard, CLI, or Slack — rather than only through code.
◆ Where it's heading
The throughline is making notification operations conversational and self-serve: agent skills, dynamic audiences buildable by an agent, a hosted preference center non-engineers can configure, and now the agent inside Slack. Knock is widening who can operate the system beyond developers while keeping its API-first core.
◆ Prediction
Expect the agent surface to keep expanding — more data sources beyond Shopify and deeper agent actions — pulling notification configuration out of code and into conversation and the dashboard.
Expo
6.3INFRA · APIS
Expo is running its SDK and EAS release engine at a fast, steady clip.
◆ Current state
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.
◆ Where it's heading
Two threads: keeping the SDK on a rapid major-version cadence, and deepening EAS as the paid cloud around it (workflows, device registration, testing insights). The MCP server going free signals interest in making Expo projects addressable by AI coding assistants. Expect the SDK cadence to hold and EAS to keep adding CI and testing surface.
◆ Prediction
Next likely: point releases and migration guidance following SDK 57, and continued EAS Workflows and testing features. Specific features are hard to call from the stub-level content in this feed.
