In their own words
StackBlitz
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.
Theia IDE
Theia IDE is an open-source, AI-native development environment for cloud and desktop, built on the Theia Platform. Users can select cloud, self-hosted or local AI models and create custom agents. It integrates official SDKs for providers including OpenAI, Anthropic and Google, and sends AI data to the provider the user chooses. The IDE supports VS Code extensions through Open VSX, though some Microsoft-proprietary extensions are unavailable and some extension API features may not work as expected. Language support uses the Language Server Protocol, including for Python, Java, JavaScript and C++. Workspace Trust puts untrusted folders in Restricted Mode and disables features that could execute code or read sensitive workspace content, but the project says this protection is still maturing. The IDE does not collect or transmit user activity, project details or code, though it can check for IDE and extension updates. The ready-to-use IDE is free at free. Its online demo is limited to 30 minutes per session. The modular Theia Platform can be used to build customized or white-labeled cloud and desktop IDEs and tools.
