Works great with Angular SPAs. Our web UI is actually an Angular SPA hosted on Netlify and using our API.
You can easily setup a rewrite rule to serve your index.html instead of giving 404's so it works with history push state and we also just added support for integrating with services like prerender.io or brombone for SEO.
The last part is not in our docs or UI yet, but just write us and we'll get you setup...
