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 Vapi?
Vapi widens its transcriber menu as Soniox hits GA and Deepgram Flux goes multilingual
Vapi is a platform for building voice AI agents. The substantive recent shipping is concentrated in its speech-to-text layer: the Soniox transcriber reached general availability for all customers, and Deepgram's Flux model gained multilingual support — both configurable per assistant. Most other weekly changelog entries in this window are empty placeholders with no described changes.
Expo vs Vapi: 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.
Vapi
5.0INFRA · APIS
Vapi widens its transcriber menu as Soniox hits GA and Deepgram Flux goes multilingual
◆ Current state
Vapi is a platform for building voice AI agents. The substantive recent shipping is concentrated in its speech-to-text layer: the Soniox transcriber reached general availability for all customers, and Deepgram's Flux model gained multilingual support — both configurable per assistant. Most other weekly changelog entries in this window are empty placeholders with no described changes.
◆ Where it's heading
The visible direction is widening transcriber choice and quality for real-time, multilingual voice agents. Within a short span Vapi promoted one new STT provider to GA (Soniox) and extended multilingual coverage on another (Deepgram Flux), both emphasizing low latency and turn-taking — the parts of a voice agent users feel most. The thin, content-free weekly entries make the rest of the roadmap hard to read from the changelog alone.
◆ Prediction
Expect continued expansion of the transcriber/provider menu and multilingual coverage; beyond the speech-to-text layer the changelog is too sparse to call a confident next move.
