Contribution guidelines and code of conduct

Thank you for your interest in contributing! Please see the Mattermost Contribution Guide which describes the process for making code contributions across Mattermost projects and join our Contributors community channel to ask questions from community members and the Mattermost core team.

When you submit a pull request, it goes through a code review process outlined here.

All contributions must adhere to the following Code of Conduct.

We also expect you to adhere to our Community Expectations guidelines while participating within the Mattermost community.

Our Pledge

We as members, contributors, and leaders pledge to make participation in our community a harassment-free experience for everyone, regardless of age, body size, visible or invisible disability, ethnicity, sex characteristics, gender identity and expression, level of experience, education, socio-economic status, nationality, personal appearance, race, religion, or sexual identity and orientation.

We pledge to act and interact in ways that contribute to an open, welcoming, diverse, inclusive, and healthy community.

Our Standards

Examples of behavior that contributes to a positive environment for our community include:

  • Demonstrating empathy and kindness toward other people

  • Being respectful of differing opinions, viewpoints, and experiences

  • Giving and gracefully accepting constructive feedback

  • Accepting responsibility and apologizing to those affected by our mistakes,

    and learning from the experience

  • Focusing on what is best not just for us as individuals, but for the

    overall community

Examples of unacceptable behavior include:

  • The use of sexualized language or imagery, and sexual attention or

    advances of any kind

  • Trolling, insulting or derogatory comments, and personal or political attacks

  • Public or private harassment

  • Publishing others' private information, such as a physical or email

    address, without their explicit permission

  • Other conduct which could reasonably be considered inappropriate in a

    professional setting


This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.


Reporting a Violation

There are several ways you can report a Code of Conduct violation:

  • On the Mattermost Community server: Send a direct message to @mattermostconduct.

    • If the violation is in a public or private channel, include a link to the conversation being reported.

    • If the violation is in a direct message conversation, provide screenshots.

  • On the Mattermost forum: Send a message to @mattermostconduct.

All complaints will be reviewed and investigated promptly and fairly.

All community leaders are obligated to respect the privacy and security of the reporter of any incident.

All reports will remain anonymous. The exception is direct message violations: while we cannot provide reporter anonymity in those situations, they will be handled with extra care so as to not escalate the situation. A draft of the violation message will be sent to the reporter for final review before it is sent.

Enforcement Responsibilities

Community leaders are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.

Community leaders have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.

While the Community leaders are responsibile for handling violations, we ask that you do your best to immediately disengage and report infractions quickly to ensure situations do not escalate.

Enforcement Guidelines
