## Meaning

A developer or team responsible for maintaining, reviewing, and making decisions about a specific part of the codebase. Code owners are typically designated to ensure code quality and consistency in their areas.

In software development, a code owner is a person or group who has primary responsibility for a particular module, service, or section of code. This role is critical in larger organizations where different teams work on different parts of the system. Code owners are expected to review pull requests, approve changes, and maintain the quality and documentation of their code areas. They act as subject matter experts and gatekeepers, ensuring that changes align with architectural decisions and best practices. Many organizations use CODEOWNERS files in their repositories to explicitly define who owns what, automating notifications when relevant code is modified. Being a code owner comes with both authority and responsibility—you have decision-making power but also accountability for the code's reliability and performance.

## When you hear it

During code review, the code owner approves or requests changes to ensure quality standards are maintained.

## Examples

- **in a standup:** "The API gateway code owner will handle performance improvements this sprint."
- **in a code review:** "Since you're the code owner, please review these changes to the authentication system."
- **in a team meeting:** "We need to establish clear code owners for each microservice to improve accountability."

## What native speakers say

- "The code owner needs to approve this pull request."
- "We should assign a code owner to the payment module."
- "Make sure the code owner reviews this before merge."

## Common mistakes

- ✗ "He is the code owner of our company." → ✓ "He is the code owner of the payment processing module." (Code owner refers to responsibility for code sections, not business or company ownership.)
- ✗ "We code owner this project yesterday." → ✓ "We assigned code owners to this project yesterday." (Code owner is a noun describing a role or person, not typically used as a verb. Use assign, designate, or name instead.)
- ✗ "All code owners must code own the entire system." → ✓ "All code owners must maintain their assigned sections of the system." (Code owners are responsible for specific areas, not the entire system.)

## Be careful

Do not confuse with 'owner' of a company or product. Code owner refers to responsibility for specific code sections, not business ownership.

## FAQ

### What does code owner mean in software engineering?

A code owner is a developer or team member who has primary responsibility for a specific section of code. They review changes, approve modifications, and ensure quality standards in their assigned area. In large organizations, code owners help manage the review process and maintain consistency across different parts of the codebase.

### How do you use code owner in a sentence at work?

You typically use it when discussing responsibility or review processes. For example: 'We need the code owner to approve this before we merge,' or 'Who is the code owner for the payment module?' It is also used in documentation: 'Code owners are listed in the CODEOWNERS file.'

### Is code owner formal or informal?

Code owner is neutral in formality. It is used in both casual conversations and formal documentation. It is professional and standard terminology in the software industry, appropriate for standups, documentation, and formal meetings.

### What is the difference between code owner and maintainer?

Code owner specifically refers to someone responsible for a code section within a company or team. Maintainer is a broader term often used for open-source projects to describe someone who maintains a library or project. In many contexts they are used similarly, but maintainer has a wider scope.

### Can one person be the code owner of multiple modules?

Yes, one person can own multiple modules, though this depends on team structure and workload. However, many teams prefer to have primary and secondary code owners for important modules to avoid single points of failure.
