Google started out with indexing / organizing publicly accessible data. And later added all kinds of tools to manage organizational and personal data. The main source of revenue is advertising.

Tiki Suite can be seen as a FLOSS self-hosted alternative to Google Apps. So for most of the tools Google offers to manage your organizational data (including personal data if it's for home/family use) , Tiki Suite has an alternative. However, Tiki Suite is not in the game of indexing public data. Although something like DuckDuckGo or YaCy could be added later on.

Organizational data

• Gmail -> Kolab, including Roundcube or Thunderbird
• Calendar -> Kolab for appointments and Tiki Calendar for public events
• Docs -> Tiki Wiki with or without WYSIWYG
• Sheets -> Tiki Spreadsheet
• Slides -> Tiki Slideshow
• Drawings -> Tiki Draw
• Hangouts -> Otalk & Jitsi
• Voice -> FreeSWITCH and FusionPBX
• Drive -> Tiki File Gallery
  • Data stored on ClearOS Flexshare and Ind.ie Pulse for automated sync
• Sites -> Various feature in Tiki: Wiki, Blog, RSS, etc.
• Contacts -> Tiki Trackers can be configured as a CRM. But even better would be to integrate with Kolab to have better integration in mail system
• Apps Script -> For End user programming, use the existing feature set in Tiki. Especially Trackers. JavaScript, jQuery and many other Wiki Plugins can be used. For more advanced use cases, you can use Tiki as Framework or even direct PHP & JavaScript.
• Analytics -> Piwik
• Picasa -> Tiki File Gallery
• Tasks -> Tiki Trackers or Tiki Tasks or Kolab Tasks
• Google+ -> Tiki can be configured to make your own Social Networking site.
• Groups -> Tiki Forums
• YouTube -> Kaltura
• Google Vault -> Kolab Bonnie
• Code -> Tiki Suite doesn't yet offer Source Control Management and an Integrated development environment but this is on the radar for later.

• Blogger/Blogspot -> Tiki Blog

Other

• ChromeOS -> Lubuntu
