discontinued JetBrains discontinued Fleet on December 22, 2025, refocusing the platform into JetBrains Air — a new agentic development product in preview. Distribution ended via Toolbox and direct download. Existing AI work continues across IntelliJ, PyCharm, WebStorm, and other established IDEs through JetBrains AI Assistant.
GitHub Codespaces is a cloud-hosted development environment that spins up a full VS Code workspace in a dev container directly from any GitHub repo. Configurable via devcontainer.json, prebuilt for fast cold starts, and accessible through the browser or local VS Code. Used by teams that want zero-setup onboarding, consistent environments, and reproducible builds across platforms.
Gitpod is an open-source cloud development environment platform that launches ephemeral, pre-configured workspaces in seconds from any Git repository on GitHub, GitLab, or Bitbucket. Configured via .gitpod.yml, it ships a full VS Code / JetBrains IDE, cached prebuilds, and workspace snapshots — eliminating 'works on my machine' for distributed teams and open-source contributors.
StackBlitz is a browser-based development environment powered by WebContainers — a WebAssembly micro-OS that runs Node.js natively inside the browser. Boot full-stack Next.js, Vite, Angular, or Astro apps in milliseconds with no remote VM, share live via URL, and embed interactive code examples in docs. Also the home of Bolt.new, StackBlitz's AI full-stack app builder.
