One repository is manageable. Ten repositories get complicated. A hundred repositories become overwhelming. As your organization grows, multi-repository maintenance becomes a critical challenge - maintaining consistent quality, coordinating updates, and ensuring nothing falls through the cracks.
This guide covers strategies for maintaining code quality across many repositories. When single-repo practices don't scale, you need systematic approaches to multi-repo maintenance.
The Multi-Repo Challenge
Why multiple repositories are harder to maintain.
Scale Complexity
Numbers create challenges:
Scale challenges:
- Inconsistent standards across repos
- Updates needed everywhere
- Different code ages
- Different team ownership
- Visibility gaps
Each repository adds management overhead.
Coordination Difficulty
Keeping things aligned:
Coordination challenges:
- Breaking changes affect many repos
- Dependency updates across repos
- Standard changes need propagation
- No single view of state
Coordination across repos is hard.
Discovery Problems
Finding what needs attention:
Discovery challenges:
- Which repos need updates?
- Which repos have security issues?
- Which repos are unmaintained?
- What's the overall health?
Discovery is harder at scale.

Ownership and Responsibility
Who maintains what.
Clear Ownership
Every repo has an owner:

- No orphan repos
Ownership enables accountability.
Ownership Tracking
Know who owns what:
@devonair ownership tracking:

Track to prevent gaps.
Handling Orphans
Unowned repositories:
@devonair orphan handling:
- Identify orphan repos

Orphans need resolution.
Shared Ownership
Multi-team repositories:
@devonair shared ownership:

Multi-repository maintenance requires systematic approaches that single-repo practices can't provide. By building visibility, establishing consistent standards, enabling coordinated updates, and automating at scale, you can maintain quality across many repositories without drowning in management overhead.
FAQ
How many repositories require a different approach?
There's no magic number, but once manual per-repo attention becomes impractical - often around 10-20 repositories - you need systematic approaches. The earlier you adopt multi-repo practices, the easier the transition.
Should we consolidate to fewer repositories?
Sometimes. Consolidation has benefits (easier coordination) and drawbacks (larger blast radius, slower builds). Consider consolidation for tightly coupled code, but don't force it. Multi-repo tooling often works better than forced consolidation.
How do we handle legacy repositories with different standards?
Tier them appropriately. Grandfather existing repos at their current state. Prevent new repos from starting that way. Gradually bring legacy repos up to standard as they're touched.
Who should own multi-repo tooling and standards?
Typically a platform or developer experience team. They provide tooling and set standards; individual teams adopt them. The central team enables rather than controls.
