• run tests / lint
• e2e tests — Cypress GH Actions https://github.com/cypress-io/github-action#start-server
• authenticated API calls (are headers forwarded?)

Netlify vs Zeit

• There is no CI functionality out of the box, both will need CI integration e.g. GH Actions

Zeit

• More powerful regex rewrites similar as in NGINX
• Great GH integration. Easier access to multiple deployments from github history (still possible with Netlify but requires visiting Netlify's UI) e.g.
• Having now dev is pretty neat — it creates "local environment" of zeit framework and allow you to test e.g. server functions (Netlify has something similar in beta now https://www.netlify.com/products/dev/)
