Microsoft Dev Box vs StackBlitz

Microsoft Dev Box provides developers self-service access to ready-to-code cloud workstations. Organizations can configure environments using YAML image definitions, custom Azure Compute Gallery images, or Azure Marketplace images. Developers can manage multiple boxes through a portal for separate projects, workloads, or tasks. Administrators can use autostop schedules and hibernation to control costs, and each provisioned box automatically enrolls in Microsoft Intune. Identity uses Microsoft Entra ID, with optional on-premises Active Directory Domain Services support; disks are encrypted by default with a platform-managed key. Network choices include Microsoft-hosted connections and customer-managed Azure networks. Users can connect with Windows App on listed desktop and mobile systems or through a browser. Windows Subsystem for Linux is supported for Linux development scenarios. Dev Box is in maintenance mode, with no additional features planned, and Microsoft recommends Windows 365 for virtualized developer environments. The service fully retires at 17:00 UTC on September 18, 2028; its closing-down period begins at 16:00 UTC on September 14, 2026. It requires work or school accounts, not personal accounts or guest access through Microsoft Entra B2B collaboration.

StackBlitz is a browser-based full-stack web IDE for the JavaScript ecosystem. Its WebContainers run Node.js development environments inside a browser tab, and the service lists millisecond startup and offline work. StackBlitz presents rapid prototyping and coding interviews as use cases. Integrations include a Figma plugin, Storybook addon, and userscript for opening GitHub projects in Codeflow. Viewing and editing projects needs no account, but saving or collaborating requires GitHub. WebContainers depend on SharedArrayBuffer and cross-origin isolation. Enterprise options connect GitHub Enterprise, GitLab, Bitbucket, private npm registries, JFrog Artifactory, and Sonatype Nexus. Enterprise code runs in an isolated browser sandbox with SAML2 single sign-on, an admin portal, and self-hosting on bare metal or in a VPC through Kubernetes. Plans include free access and a 14-day trial; listed plan prices are not provided.
