the flow experts

Flow brings soundness and type safety to JavaScript, eliminating whole classes of bugs and making JS development easier, more scalable and more productive.

Flow Support & Consulting

Ever since its first public release in 2014 we've been helping push Flow forward and we've become the leading experts in this technology (outside of Facebook of course). With Flow we help companies radically improve their code quality, documentation and catch bugs before they get anywhere near production.

We're the company behind projects such as flow-runtime and babel-plugin-typecheck which make it easier to bring Flow to existing codebases.
