What it 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 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.
