CodeSpy
An open-source AI reviewer that catches bugs, improves code quality, and integrates directly into your PR workflow, without sacrificing control or security.

Why CodeSpy?
Most AI code reviewers are:
- ❌ Black boxes
- ❌ SaaS-only
- ❌ Opaque about reasoning
- ❌ Risky for sensitive codebases
CodeSpy is different:
- 🔍 Transparent reasoning
- 🔐 Self-hostable
- 🔄 Native PR integration
- 🧩 Extensible architecture
- 📦 100% open-source
Built for engineering teams that care about correctness, security, and control.
Features
- 🔒 Security Analysis — Detects common vulnerabilities (injection, auth issues, data exposure) with CWE references
- 🐛 Bug Detection — Identifies logic errors, null references, resource leaks, edge cases
- 📝 Documentation Review — Checks for missing docstrings, outdated comments, incomplete docs
- 🔍 Intelligent Scope Detection — Automatically identifies code scopes (frontend, backend, infra, microservice in monorepo, etc.)
- 🧠 Cross-Review Memory — Agents learn patterns, constants, and domain knowledge from past reviews of the same codebase
- 💰 Cost Tracking — Track LLM calls, tokens, and costs per review
- 🤖 Model Agnostic — Works with OpenAI, AWS Bedrock, Anthropic, Gemini, Ollama, and more via LiteLLM
- 🐳 Docker Ready — Run locally or in the cloud with Docker
GitHub & GitLab — Works with both platforms, auto-detects from URL
- 🖥️ Local Reviews — Review local git changes without GitHub/GitLab — diff against any branch, ref, or review uncommitted work
- 🧩 MCP Server — IDE integration via Model Context Protocol — trigger reviews from AI coding assistants without leaving your editor
- 🔌 GitHub Action — One-line integration for automatic PR reviews

Quick Start
Get up and running in 30 seconds:
# 1. Set your Git token (or let codespy auto-discover from gh/glab CLI)
export GITHUB_TOKEN=ghp_xxxxxxxxxxxxxxxxxxxx # For GitHub
# OR
export GITLAB_TOKEN=glpat-xxxxxxxxxxxxxxxxxxxx # For GitLab
# 2. Set your LLM provider (example with Anthropic)
export DEFAULT_MODEL=anthropic/claude-opus-4-6
export ANTHROPIC_API_KEY=sk-ant-xxxxxxxxxxxxxxxxxxxx
# 3. Review a PR or MR!
codespy review https://github.com/owner/repo/pull/123
# OR
codespy review https://gitlab.com/group/project/-/merge_requests/123
codespy auto-discovers credentials from standard locations (~/.aws/credentials, gh auth token, glab auth token, etc.) - see Configuration for details.
