Rooibos is an independent open-source project maintained exclusively by volunteers.
You might want to help! Get in touch via the slack group or raise issues.
To work on Rooibos locally:
npm install
npx ropm copy # copies the framework's ropm dependencies into framework/src
npm testnpx ropm copy is required because npm install alone doesn't copy the ropm modules the framework depends on. npm run build also runs it for you, and the test/device scripts will tell you if you've forgotten it.

Yes, it's been used in production by quite a few respectable companies. There are 10,000's of tests in production.
We at RokuCommunity love rooibos, and regularly keep it up to date.
Dependencies flagged by npm audit that we have reviewed and chosen not to upgrade are tracked in audit-ci.jsonc. Each entry includes the advisory ID, the date it was added, and the reason it does not apply to this project.
