One graph. Two jobs.

Xolvyn parses your repository once and uses the result twice: to help engineers understand the codebase, and to investigate findings with dependency context.

Dependency Graph

Explore file dependencies.

Xolvyn analyzes supported source files to build an interactive map of resolved imports. Explore module connections and circular dependencies alongside the source.

App Router
Auth
API
Database
Cache
Security Audit

Investigate detected security findings.

Review potential source-code and dependency issues with severity, locations and remediation suggestions. Check the completed analysis coverage; no findings does not establish security.

PR Impact Analysis

Review a change’s structural context.

Inspect changed files and their import dependents. Structural connections suggest a review scope, not proof of runtime impact or safety.

AI Mentor

Ask questions with repository context.

Ask @mentor about the repository using its analysis as context. Check important answers against the linked files.

Where is the auth logic and how does it connect to the API?

Inspect lib/auth.ts and its import relationship with api/auth/[...nextauth]/route.ts. Check the source before inferring execution order.

Illustrative answer; verify against the source

How the engine works.

A transparent pipeline. No magic.

01

AST parsing

Supported source files are analyzed to map resolved imports, exports and architectural layers.

02

Security findings

Review detected findings with severity, source locations and structural dependency context. Import reach does not establish exploitability.

03

Explore the results

Read source files, follow dependencies and ask questions using the repository analysis as context.

Private & Secure

How your code is processed.

Analysis uses a temporary server-side clone, with cleanup attempted afterward. Review data handling before connecting private code.

Temporary analysis clone

Analysis uses a temporary server-side clone. Cleanup is attempted after the scan; analysis metadata is saved for signed-in users.

AI with repository context

AI features use repository analysis as context. Check important answers against the linked files and review provider handling before connecting private code.

Bring your own scanner

Where enabled by your plan, connect SonarQube or SonarCloud to import findings as metadata. Repository analysis uses a separate temporary clone.
