Contributing to Valgrind

If you would like to contribute to Valgrind's development, there are a number of ways you can help.

Bug Reports

Bug reports are good. Good bug reports are even better. They should be submitted to our Bugzilla site (instructions are here). Please follow the guidelines about writing good bug reports. Small sample programs that exhibit a bug are particularly helpful.


Valgrind's documentation is not always kept up to date. Any documentation patches that help in this respect are welcome. Please send them to the valgrind-developers list.

Software Infrastructure, Code and Research

If you are interested in writing code for Valgrind itself or its infrastructure, or doing research with it, please consult our project suggestions page.
