10 free apps I wish were open source

When it comes to web applications, I think free and open source software fans are settling for “free” instead of looking for the freedom they would get from open source.

Here are some free applications that I wish had open source software equivalents.  I am not unhappy with these applications. I just wish I had open source software alternatives that were as good!

Here are 10 of the good web applications that I use daily that don’t have good enough open source software equivalents.

  1. Gmail. How many free software developers use Gmail as their primary email interface?
  2. Remember the Milk. I want a way to sync tasks across multiple computers, tag them, date them, prioritize them and share them with other users.
  3. TripIt. I forward any reservation to it and it adds it to my itinerary. I can also share with friends to coordinate travel plans or just to share where we are.
  4. Facebook. There’s Identica as an alternative to Twitter but there’s no open source software alternative to Facebook.
  5. Delicio.us/Diigo. Mozilla is working on tools to help me synchronize my bookmarks across multiple machines. I also want to share and search them.
  6. Kayak.com. The best way to find cheap airfare with all the options you need.
  7. Doodle. Ever tried to schedule a meeting with lots of busy people in different time zones?
  8. Google calendar. I can manage my calendar from any where and invite others to meetings. All synced on the web, not dependent on any particular machine I’m on.
  9. Google reader. Judging from how many open source software users share items with me in Google reader, a lot of us are using this RSS reader to follow our favorite websites.
  10. Dropbox. Dropbox and UbuntuOne have become the default way for users to access files across multiple machines, remotely and to share them. Why don’t we have an open source software option yet?

Why hasn’t open source software kept up with the web application space? What needs to happen for us to have open source software web applications in these spaces?

What other spaces are also missing open source software options?
