Expo vs Auth0
Side-by-side trajectory, velocity, and editorial themes.
Extending from build-and-ship into runtime observability and CI primitives.
Expo is in active release mode — SDK 55 landed in February, SDK 56 beta is now out, and the team is filling the gaps with build-time wins (Gradle and compiler caches), new product surfaces (Expo Observe in private preview), and developer-ergo additions like GitHub sign-in. A separate thread on Expo Go's App Store posture keeps recurring, signaling continued platform-store friction.
The arc is broadening past "build and ship React Native apps" into the operational layer around them: production observability with Expo Observe, CI primitives via MCP tools and compiler caches, and authentication ergonomics. The SDK cadence remains the metronome, but the most interesting motion is happening adjacent to it — at the dev-experience and runtime-ops edges.
Expo Observe is the directional bet for 2026; expect it to exit preview tying crash, performance, and user-flow analytics directly to the EAS pipeline. On the iOS side, expect ongoing posts and a push toward Dev Client and bare workflows as the more durable distribution path, with Expo Go reserved for prototyping rather than production handoff.
Auth0 ships Auth for MCP GA and starts unbundling the rest of identity for AI agents.
Auth0 just made Auth for MCP generally available — a bundle of CIMD client registration, On-Behalf-Of token exchange, and OAuth resource-parameter compatibility purpose-built for AI agents talking to MCP servers. Around it, the team is reworking core identity primitives: non-unique emails reached GA, online refresh tokens entered beta with session binding, and the Account API now supports step-up auth for sensitive scopes. Smaller polish items (CMD+K palette, Resend GA, signing algorithm coverage) round out the release stream.
Auth0 is repositioning from a B2C/B2B login provider to an authorization layer for agent ecosystems. The MCP work is the centerpiece, but the supporting moves — session-bound refresh tokens, step-up auth on the Account API, non-unique emails — all point at use cases where users, agents, and resources have more complex relationships than classic OIDC was designed for. Outbound event streams to AWS EventBridge and Okta Workflows extend the same direction outward.
Expect Auth for MCP to gain a managed catalog of pre-vetted MCP clients and deeper Actions-based policy hooks for OBO token exchange, plus online refresh tokens reaching GA within a quarter.
