What is Windmill?
Windmill hardens its runtime: daemonless containers, SSH execution, dev/prod workspaces.
Windmill is an open-source developer platform that runs scripts, flows, and apps as a workflow and internal-tools engine. Its changelog is a genuine, dense stream of runtime and operations features. The current cluster centers on execution flexibility (containers, remote SSH, SQL S3 inputs), environment safety (dev/prod workspaces), and enterprise observability and governance (OTEL tracing, audit-log export, Kubernetes autoscaling).
What is Expo?
Expo is running its SDK and EAS release engine at a fast, steady clip.
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.

◆ Current state
Windmill is an open-source developer platform that runs scripts, flows, and apps as a workflow and internal-tools engine. Its changelog is a genuine, dense stream of runtime and operations features. The current cluster centers on execution flexibility (containers, remote SSH, SQL S3 inputs), environment safety (dev/prod workspaces), and enterprise observability and governance (OTEL tracing, audit-log export, Kubernetes autoscaling).
◆ Where it's heading
Windmill is maturing along two tracks at once: a more capable, safer execution runtime (sandboxed multi-tenant containers without a Docker daemon, remote SSH targets) and the enterprise scaffolding around it (environment promotion, distributed tracing, audit export, smarter K8s scale-in). The direction is making the platform safe to run untrusted, multi-tenant code at scale while giving teams real dev/prod discipline.
◆ Prediction
Expect continued investment in isolation/runtime breadth and enterprise operability — more sandboxing options, deeper observability, and workspace/promotion tooling. The cadence is fast and consistent, with the daemonless container runtime the most likely lever for new multi-tenant and cloud use cases.
Expo
6.3INFRA · APIS
Expo is running its SDK and EAS release engine at a fast, steady clip.
◆ Current state
Expo's feed shows its core release machine turning over: SDK 57 just shipped roughly six weeks after SDK 56's stable release, alongside EAS Workflows automation (iOS device registration), Maestro test insights, and an MCP server now on the free plan. The work spans the SDK, the build/CI cloud (EAS), and testing. Several entries carry only 'Read more' stubs, so feature detail is thin in this feed.
◆ Where it's heading
Two threads: keeping the SDK on a rapid major-version cadence, and deepening EAS as the paid cloud around it (workflows, device registration, testing insights). The MCP server going free signals interest in making Expo projects addressable by AI coding assistants. Expect the SDK cadence to hold and EAS to keep adding CI and testing surface.
◆ Prediction
Next likely: point releases and migration guidance following SDK 57, and continued EAS Workflows and testing features. Specific features are hard to call from the stub-level content in this feed.
