Prometheus is developed in the open. Here are some of the channels we use to communicate and contribute:

IRC: #prometheus on (for the easiest start, join via Riot)

User mailing lists:

Twitter: @PrometheusIO

Issue tracker: Use the GitHub issue tracker for the various Prometheus repositories to file bugs and features request. If you need support, please send your questions to the prometheus-users mailing list rather than filing a GitHub issue.

Please do not ask individual project members for support. Use the channels above instead, where the whole community can help you and benefit from the solutions provided. If community support is insufficient for your situation, please refer to the Commercial Support section below.


We welcome community contributions! Please see the file in the respective Prometheus repository for instructions on how to submit changes. If you are planning on making more elaborate or potentially controversial changes, please discuss them in the developers IRC channel or on the mailing list before sending a pull request.

IRC: #prometheus-dev on

Development mailing list: prometheus-developers โ€“ for discussions around Prometheus development

Developer summits

We strive to be as open and public as possible. Technical discussions happen on the development list, our in-person meeting notes are public, and we have public calls. Below, you can find links to our developer summits at PromCon 2017 & 2018, respectively. These developer summits are open to join upon request as long as we have capacity. Preference is given to friendly projects and companies, plus diversity. Attendees are free not to be listed in the public meeting notes.

Project Governance

Prometheus is an independent open-source project and not controlled by any single company. To emphasize this we joined the Cloud Native Computing Foundation in 2016.

Within the project, we make decisions based on these rules.

Code of Conduct

To make Prometheus a welcoming and harassment-free experience for everyone, we follow the CNCF Code of Conduct.

Commercial Support

This is a list of third-party companies and individuals who provide products or services related to Prometheus. Prometheus is an independent open source project which does not endorse any company. The list is provided in alphabetical order.


Prometheus was started by Matt T. Proud and Julius Volz. The majority of its initial development was sponsored by SoundCloud.

We would also like to acknowledge early contributions by engineers from Docker and Boxever.

Special thanks to DigitalOcean for providing hosting resources.
