What StackBlitz is

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 says these environments can start in milliseconds. The site lists offline work as a capability and describes rapid prototyping and coding interviews as uses for its browser-based workspace. Integrations include a Figma plugin, a Storybook addon, and a userscript that opens GitHub projects in Codeflow. Viewing and editing projects does not require an account, but saving work or collaborating requires GitHub. WebContainers rely on browser features including SharedArrayBuffer and cross-origin isolation. Enterprise options list GitHub Enterprise, GitLab, Bitbucket, private npm registries, JFrog Artifactory, and Sonatype Nexus. Enterprise code runs in an isolated browser sandbox, with SAML2-based single sign-on, an admin portal, and self-hosting on bare metal or in a VPC using Kubernetes. The plans include a free option and a 14-day trial; listed plan prices are not provided.
