Web based IDEs

Hi

I’m looking for a free of charge, free (as in free speech) web based editor with no login (I don’t want to pay with my personal data) for web and applications projects, compatible with Git and Subversion. I already tested lots of them:

  • Ecco seems to be abandoned
  • Codiad SVN plugin is abandoned and there is no language syntax highlighting for Java
  • I haven’t succeeded in using Eclipse Orion
  • ICEcoder seems to be only for web projects
  • CodePen is only for web projects
  • Codeanywhere requires a login like Cloud9, Koding, …
  • I haven’t found how to use Git or SVN with ecoder
  • ShiftEdit supports Java, SFTP, FTP but I don’t know if it supports SVN and it is neither free nor free of charge
  • JSFiddle is only for web projects
  • Mozilla WebIDE doesn’t support Java

I would like to edit some source code on some machines unable to support Eclipse (occasionally, mainly with my smartphone) and on some computers on which I don’t want to let any track of Git and Subversion usage or on which I’m not allowed to install an IDE. It’s mainly for web projects as if there is no way to install OpenJDK, I won’t be able to test my Java code but sometimes it would be enough for prototyping a bit.

Which web based IDE(s) do you use? Which one would you advise me to use?
