BugLens reviews every pull request before your team does - catching bugs, vulnerabilities, and style violations using your own codebase as context.

// how it works
Three agents.
One verdict.
BugLens uses a LangGraph pipeline of three specialised AI agents that work in sequence on every PR diff.
Lens agent
Parses diffs with AST analysis. Detects OWASP vulnerabilities, logic errors, and anti-patterns at the line level.
Context agent
Searches your team's docs, past PR comments, and standards via RAG. Every review knows your codebase.
Review agent
Writes structured inline comments with severity scores and one-click suggested fixes - posted directly on the PR.
GitHub native
Install via GitHub App in 60 seconds. Works on any repo, any language. No config files needed to get started.
MCP server
Expose BugLens agents to any MCP-compatible AI tool. Let your IDE assistant query review history and standards.
Review analytics
Track bug patterns, recurring violations, and team-wide code health over time on your BugLens dashboard.
