We love a good query. Here are a few common ones to get you started.

Are Elasticsearch, Kibana, Beats, and Logstash still open source?

Yes. We did not change the license of any existing Apache 2.0 code. We only opened the code of X-Pack under a commercial license and added it to the existing Elasticsearch, Kibana, Beats, and Logstash repositories.

How do I contribute to Elasticsearch, Kibana, Beats, and Logstash now that there is non-Apache 2.0 code in the repository?

The same way you always have. There are no changes to the contributor license agreement or contribution process. What did change is that you can now contribute to X-Pack features. Interested in an extra chart or view for monitoring Elasticsearch or an improvement to the Grok Debugger for Logstash? You can now participate in improving those features the same way you have with our open source products.

If the code of X-Pack is open, does that mean it's all free?

No. Many features in X-Pack are free, such as monitoring, tile maps, Grok Debugger, and Search Profiler. Some features in X-Pack are paid, and require a license that comes with a Gold or Platinum subscription.

Is X-Pack now open source?

Updated on 2018-04-24 with a link to the Elastic License

Open source licensing maintains a strict definition from the Open Source Initiative (OSI).

As of 6.3, the X-Pack code is open under the Elastic License. However, it will not be 'open source' as it will not be covered by an OSI approved license. The interaction model for open X-Pack will be identical to the open source Elastic Stack, including the ability to inspect code, create issues and open pull requests via our existing GitHub repositories.
