Expo vs Vercel
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.
Vercel trials flat-rate CDN pricing and lines up its sandbox as the runtime for managed AI agents.
Vercel opened a Limited Beta of Flat Rate CDN for Pro teams — fixed monthly fee instead of usage-based bandwidth — and shipped a Claude Managed Agents integration for Vercel Sandbox in the same week. AI Gateway gained Gemini 3.5 Flash and provider sorting by cost, latency, or throughput. Around that, Firewall-mitigated traffic became free, monorepos got consolidated GitHub commit statuses, and Trusted Sources brought OIDC to deployment protection.
Two strategic moves are visible: a hedge against the usage-pricing backlash (Flat Rate CDN, free firewall-mitigated traffic) and a serious bid to host AI agent workloads (Sandbox + Claude Managed Agents, AI Gateway provider routing controls). Developer-experience polish continues underneath — natural-language WAF rules, native curl in CLI, protected source maps.
Expect Flat Rate to widen from CDN to compute and ISR cache once the beta closes, and Vercel Sandbox to gain integrations with at least one more major agent runtime beyond Claude.
