What is Expo?
SDK 56 ships and MCP integration goes free — opening AI-coding workflows to every Expo developer.
Expo just shipped SDK 56 (following a May 6 beta) and made the Expo MCP Server available on the Free plan, opening up the AI-coding-assistant integration path to all users. Around it: continued workflow changes for Expo Go's project loading, Android build acceleration via Gradle cache, and the recurring App Store status update for Go users.
What is Knock?
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
Expo vs Knock: editorial side-by-side
Expo
5.0INFRA · APIS
SDK 56 ships and MCP integration goes free — opening AI-coding workflows to every Expo developer.
◆ Current state
Expo just shipped SDK 56 (following a May 6 beta) and made the Expo MCP Server available on the Free plan, opening up the AI-coding-assistant integration path to all users. Around it: continued workflow changes for Expo Go's project loading, Android build acceleration via Gradle cache, and the recurring App Store status update for Go users.
◆ Where it's heading
The two lines being pushed hardest are (a) AI-coding integration — MCP now free, expanded GitHub bot permissions earlier in the quarter — and (b) build pipeline performance. Expo Go remains a maintenance surface, with the May post and loading-behavior changes hinting at continued constraints on what the iOS App Store will allow. The SDK cadence (55 → 56) stays roughly quarterly.
◆ Prediction
Expect more MCP-server capabilities now that the gate is open, continued EAS Build optimization, and the next SDK 57 beta before the end of summer if the prior cadence holds. Expo Go's iOS story remains the open question.
Knock
6.3INFRA · APIS
Knock is pushing its agent into more surfaces while making notification config a no-engineering job.
◆ Current state
Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.
◆ Where it's heading
The direction is toward less engineering involvement per change — agents, dashboard-built audiences, and hosted end-user UI all shorten the code path. Integrations like the Shopify data source extend Knock's triggers into commerce events, broadening what notifications can be driven by. The agent and the dashboard keep absorbing tasks that previously required custom code.
◆ Prediction
The next moves likely deepen the agent (more surfaces or skills) and add further data sources, continuing the shift toward dashboard- and agent-driven configuration over hand-written integration code.
