What is Monorepo Support?

In a monorepo, one repository holds many services owned by different teams with different languages and standards. A tool that treats it as a single unit produces one undifferentiated finding list and one meaningless quality grade.

Real support means scoping analysis to changed paths, applying different configuration per subdirectory, and routing findings to the owning team. Without it, adoption stalls because nobody feels responsible for the shared number.

Top 18 Monorepo Support tools

Every tool in the directory documented as supporting Monorepo Support, 12 fully, 6 partially, with what its own documentation says.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.

1. 1
   AikidoCode Security PlatformPro

   Split monorepo per path (Pro+); GitLab/Azure DevOps only, no secrets scanning

2. 2
   ChatGPT / CodexAgent Coding ToolPlus

   Nested per-service AGENTS.md rules and path-based severity overrides; review pane also handles multi-repo projects.

3. 3
   Claude CodeAgent Coding Tool

   Dedicated docs cover per-package CLAUDE.md, sparse worktrees, and per-directory skills for monorepos.

4. 4
   CorgeaCode Security Platform

   BLAST endpoint-reachability analysis attributes findings to the correct sub-project within a monorepo.

5. 5
   Cursor (Bugbot)PR ReviewPro

   Nested BUGBOT.md discovery upward from changed files, glob-scoped rules, ROUTING.md product boundaries.

6. 6
   DeepSourceQuality Platform

   All tiers provide monorepo support alongside unlimited pull request reviews.

7. 7
   GitHub Advanced SecurityCode Security PlatformFree on public repos; add-on Code Security for private

   category param documented for monorepo SARIF differentiation; matrix builds run per-component analysis in parallel

8. 8
   GreptilePR Review

   Cascading .greptile/ per-directory config lets monorepo packages own strictness, rules and filters

9. 9
   QltyQuality PlatformFree (CLI)

   Sandboxed per-plugin installs, prefix/package_file scoping, directory-scoped triage, differential analysis, directory-level UI

10. 10
    QodoPR Review

    Path-pattern rule scopes, folder-level rule scoping, folder allow-listing in ignore rules

11. 11
    SnykCode Security Platform

    The CLI's --all-projects flag explicitly documents monorepo scanning, alongside --detection-depth and --exclude for multi-package repos.

12. 12
    SonarQubeQuality Platform

    Multi-project repository analysis with monorepo branch, PR, and scoped analysis.

13. 13
    CodeAnt AIPR ReviewPartial

    "Monorepo" appears only in test-coverage upload tagging docs (per-module coverage); no equivalent guidance for code-review or security scanning across a monorepo's packages.

14. 14
    CodeRabbitPR ReviewPartialPro

    Glob path filters/instructions and hierarchical per-directory config; monorepos never named explicitly

15. 15
    CodeSceneQuality PlatformPartialStandard

    Architectural definitions give subsystem, component and service-level analysis; monorepos never named explicitly

16. 16
    Gemini Code AssistAgent Coding ToolPartial

    Multiple separate repositories can be selected as chat context; scanning or configuring multiple packages within a single repository is not documented.

17. 17
    SemgrepCode Security PlatformPartial

    Dashboard project filters can target a monorepo subfolder; no wider monorepo handling documented.

18. 18
    VeracodeCode Security PlatformPartial

    Multi-module build uploads let you choose which modules to scan, adjacent to monorepo scanning; repo-scanning docs never use the term "monorepo" or describe per-directory project scoping.

What to look for

• Per-directory configuration and quality gates
• Analysis scoped to changed paths rather than the whole tree
• Ownership routing, typically via CODEOWNERS
• Pricing model, since some tools bill a monorepo as a single project, others by size
