GitHub Copilot is a free alternative to TabNine but access is limited to a small group of users currently.

Not aware of a free alternative to WallabyJS (but I can honestly say its worth it for the day job!)

When working in a Typescript/JavaScript stack the test runner WallabyJS has been a great productivity boost, as it constantly runs your tests and gives visual feedback. The debugging facilities are great too.

I also recommend TabNine - code intellisense on steroids!

I wrote a Chrome extension which demonstrates Typoglycemia by scrambling the words on whatever webpage you are on. It's similar to the OP's webpage but does not produce a constantly changing page of words.
