We use github for our code repository and code reviews, sentry.io for error reporting, asana to track our weekly objectives, slack to communicate, google hangouts for team meetings, google docs for sharing proposals, spreadsheets, various documents, and figma to share design assets. This has worked well for us so far for about a year. No complaints really.
