Just a little movement in the open source world, Sebastian is leaving Facebook.

McKenzie is also behind a newer project called Rome...

An experimental JavaScript toolchain

Rome is an experimental JavaScript toolchain. It includes a compiler, linter, formatter, bundler, testing framework and more. It aims to be a comprehensive tool for anything related to the processing of JavaScript source code.

Rome is not a collection of existing tools. All components are custom and use no third-party dependencies.

Rome is experimental and in active development. It's open for contributors and those interested in experimental tools. It is not ready for production usage. The only way to use it is to build from source.

Rome aims to be a replacement for many existing JavaScript tools. We will, however, offer integrations for components in other tools. For example, using the Rome compiler as a plugin for another bundler.

Rome is MIT licensed, and the project managed under the Contributor Covenant Code of Conduct.


Rome was started by Sebastian McKenzie, the author of Babel and Yarn

I'm sure wherever he ends up next week, he'll continue to do great things.


Based on some replies to that Twitter thread, he will keep working on Rome at least part-time.


Yup, it's his baby I guess and it was already open source and Facebook will most likely benefit from it as well even if he no longer works for their organization.


In the Tweet thread, he said he’d mention it next week, once he starts working wherever he ends up at.
