Oracle OpenGrok

Oracle OpenGrok was traditionally the most popular open source code search tool. Originally developed inside Sun Microsystems around 2004, it’s now an Oracle open source project after Oracle acquired Sun.

Sourcegraph is a good replacement for OpenGrok for almost every organization.


  • Simple interface
  • Support for non-Git repositories
  • Easy deployment (for Java shops)


  • Slow and difficult-to-manage indexing process (leading to stale results for users)
  • Poor support for searching/browsing multiple commits and branches
  • Poor scalability to many repositories and for large repositories
  • Inflexible and buggy API (using the new REST API)
