Django ORM Lens

The schema intelligence layer for Django.

Your entire model graph — live in your editor sidebar, gating your CI, and answering your AI agent over MCP. All from static parsing: no database, no runserver, no working venv.

Replaces: graph_models + django-schema-graph + hand-drawn ER diagrams + grep archaeology.

⚡ 10 seconds to first insight

uvx django-orm-lens scan      # or: pipx run django-orm-lens scan

Cold clone, broken venv, no settings module — you still get every app, model, field, and relation of the project in your terminal.

Then pick your surface — three distributions, one parser core:

MCP setup is one JSON block — see Integrations. Point DJANGO_ORM_LENS_ROOT at your Django project's absolute path.

🆓 Paid-tier capabilities, free and MIT

Schema review is a paid category nearly everywhere. A bot that reviews every pull request, analysis that follows a queryset past the function it was built in, a check that catches schema drift, index advice grounded in real table statistics — those normally sit behind a per-seat or per-database subscription.

All of it is here, MIT-licensed, with no tier gate, no seat count, no account, and no telemetry:

There is no Pro tier, and none is planned. If the tool saves you an afternoon, a star is the entire ask.

📊 Traction

If the tool saves you a grep next time you touch a strange Django project — a star helps others find it.

⚡ Install

VS Code / Cursor / Windsurf (VS Code Marketplace):

code --install-extension frowningdev.django-orm-lens

VSCodium / code-server / Gitpod / any OSS Code fork (Open VSX):

codium --install-extension frowningdev.django-orm-lens

Or search Django ORM Lens in the Extensions view — same publisher frowningdev on both registries.

Terminal & AI coding agents:

pip install django-orm-lens              # CLI only
pip install "django-orm-lens[mcp]"       # + MCP server for AI agents

Requires Python 3.9+. Zero runtime dependencies for the CLI.

Docker (v0.6+):

docker run --rm -v "$PWD:/workspace" ghcr.io/frowningdev/django-orm-lens scan --path .

Multi-arch (amd64 + arm64). No Python required on the host. Good for CI and one-off audits.

🎯 The problem

Works offline. Works on a broken venv. Works on someone else's laptop. Works in CI.

You open a Django project. It has 20 apps. You need to answer a simple question:

"Which app owns the Order model, and how is it connected to User?"
