As a member of a team, I use :

• Skype,
• Gitlab,
• Git.

1. Trello
2. Slack

GIT

• Zoho
• Bitbacket
• gist
• skype

My combo is Slack, Trello, Bitbucket. Sometimes, Gitlab and ZenHub. For screen share, zoom or hangout is good. I am a contributor to side projects :) So, tried quite a lot.

Asana for project management (free account) Bitbucket for git repos Hangouts for communication

Trello, Skype, GitHub/BitBucket, Google Docs!!

My personal combo is to use to Atlasssian toolbox (including JIRA, Confluence and Bitbucket). They are super complete, though a bit on the pricy side. But they offer a wide range of possibilities, and it's a great way to handle a project in general.

Now, with Github projects you also have a great tool available for handling collaboration with other developers, though it has less functionalities than JIRA !

Aside, of course Slack is a must I think (some people start to use Discord around here !). I also recommend Paw for teams, a super good tools when coming to API's.

I'm using:

• Project Management: Trello
• Chat/Communication: Slack
• Video Conference: Google+ Hangouts

Gitlab now has a neat little kanban board embedded in projects. Very useful for task managemet.

This is what I have been using:

• Code Management, Wiki, Project Management: GitHub
• Chat: Slack / Skype
• Forum: NodeBB
• Voice: Teamspeak / Mumble
• (Bin.) Docs: Google Docs
