Does crucible integrate with teamcity?If not then what peer code review tool can be used with Teamcity for continuous integration?
Also I have another question.... does gerrit work with subversion? I saw reitveld had some support for subversion but does gerrit has the support for svn?
Crucible doesn't integrate directly with TeamCity, however, JIRA (Atlassian's issue tracker) integrates quite nicely with both TeamCity and Crucible/FishEye.
Here are some resources for further reading:
Also, no, Gerrit only supports Git. This SO comment also suggests rietveld as an alternative for SVN.
