Eclipse Che vs StackBlitz

Eclipse Che is an open-source development environment that runs IDEs in Kubernetes. Users create workspaces from a Git repository or sample, then access them online through a browser. Visual Studio Code and JetBrains IDEs are available. Workspace definitions use Devfiles, YAML files that can be versioned with application source code, and a devcontainer configuration is listed. GitHub, GitLab, and Bitbucket identities can connect through OAuth. Teams can share a development setup by URL, and Che can run on public or private Kubernetes clusters, including self-hosted deployments. Access uses OIDC authentication and Kubernetes RBAC authorization. Enterprise support includes air-gapped networks, TLS certificates, proxies, and FIPS. Code is cloned to persistent storage by default, but other file changes disappear when a workspace stops unless stored on a persistent volume. Che is free, with no stated usage limits.

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.
