Elasticsearch is Open Source under the Apache 2 License. The code is hosted at GitHub and we love receiving contributions from our community, whether they are bug reports, feature requests, document improvements or patches to Elasticsearch itself. Have a look at our guide to How to contribute to Elasticsearch.
Sometimes it’s just easier to get help or discuss matters in real time. The #elasticsearch channel on irc.freenode.net allows for just that (webchat.freenode). Note: IRC discussions tend to exclude large parts of the community. Therefore Elasticsearch core technical discussions and decisions must take place on the mailing lists, not IRC. They don’t count otherwise.
Issues and feature requests can be filed at GitHub Issues (if you are not sure, please post a question at the mailing list first).
We welcome vulnerability reports in all of our software. Please go to our vulnerability page to see how to report a potential issue and a history of issues.
