Fisheye is a revision-control browser^[1] and search engine owned by Atlassian, Inc. Although Fisheye is a commercial product, it is freely available to open source projects and non-profit institutions.^[2] In addition to the advanced search^[3] and diff capabilities,^[4] it provides:

• the notion of changelog and changesets^[5] - even if the underlying version control system (such as CVS) does not support this
• direct, resource-based URLs down to line-number level^[6]
• monitoring and user-level notifications via e-mail or RSS^[7]

Use in open-source projects

Atlassian approves free licenses for community and open-source installations^[2] under certain conditions. Many major open source projects use Fisheye to provide a front-end for the source code repository:^[8]

Atlassian provides free licences of Fisheye and Crucible for open-source projects.^[9]

Integration

As of 2010^[update] Fisheye supported integration with the following revision control systems:^[10]

• CVS
• Git
• Mercurial
• Perforce
• Subversion

Due to the resource-based URLs, it is possible to integrate Fisheye with different issue and bug tracking systems. It also provides a REST and XML-RPC API. Fisheye also integrates with IDEs like IntelliJ IDEA^[11] via the Atlassian IDE Connector.
