Expo keeps expanding past builds into testing, observability, and AI-assisted developer tooling.
Expo's recent cadence centers on its cloud platform (EAS) as much as the SDK itself. The last month added a Maestro test-insights dashboard, iOS device-registration automation in EAS Workflows, and a free-plan MCP server for AI coding assistants, alongside the SDK 56 release. The picture is a React Native toolchain steadily absorbing the surrounding lifecycle: build, test, ship, and now observe.
Very high-cadence sandbox infra building the primitives agents need to run code
Daytona is shipping roughly every few days (v0.161 through v0.170 in this window), iterating fast on its code-execution sandbox platform. Recent releases add sandbox forking and snapshots, per-sandbox and per-region resource limits, runtime network controls, a BuildKit build path, and multi-language SDKs.

The picture is a React Native toolchain steadily absorbing the surrounding lifecycle: build, test, ship, and now observe.
The throughline is moving the end-to-end developer workflow onto EAS, from the local SDK out to CI, testing, and runtime monitoring via the Expo Observe preview. Making the MCP server free across plans signals a bet that AI-assistant access is becoming table stakes rather than a paid upsell. Each SDK release stays the anchor, but the differentiated investment is increasingly the managed cloud surface around it.
Expect Expo Observe to move from private preview toward general availability, and the Maestro test work to deepen into flake detection and CI gating. The SDK 56 line should settle into point releases as attention shifts to the next major.
Daytona is shipping roughly every few days (v0.161 through v0.170 in this window), iterating fast on its code-execution sandbox platform. Recent releases add sandbox forking and snapshots, per-sandbox and per-region resource limits, runtime network controls, a BuildKit build path, and multi-language SDKs.
The work clusters around making sandboxes a controllable, forkable primitive for AI agents: snapshot/fork to branch execution state, resource and network limits to contain it, and SDK simplification (moving execution to the daemon) to make it programmable. Daytona is building toward a fuller sandbox-orchestration layer.
Expect the forking/snapshot capability to graduate from experimental toward stable, with continued SDK and resource-control depth — the consistent themes across this release run.
