Add section for developers (SDKs) and open-source projects

• Titan (golang)
  • GCM
• Neptulon
  • ShortID
  • CA
  • CMap
    ...

It might also be worth considering to use GitHub API v3 to auto fetch projects, their build statuses, descriptions, etc. on the client side as info is already public and the API is very basic even without a JavaScript SDK.
