Ionide is an organization which builds high quality, cross platform developer tools for F#. Our flagship project is Ionide-VSCode - a Visual Studio Code plugin, with more than 1 million downloads, transforming VSCode into a fully-fledged F# IDE. But Ionide is more than just an editor plugin - we build a whole ecosystem of developer tools - from a documentation generator, to an F# LSP server, to experimental and innovative projects like F# Analyzers.
