An architecture diagram generated from your code
Not boxes someone drew once, and not a graph of every import: the areas of the product, what each one does, the customer paths through them and the rules between them — read from the repository and redrawn after every push.
In short
To generate an architecture diagram from code, a tool has to read what the code does, not only what it imports. GitMir reads a repository into a model of its areas, screens, API routes, records, customer paths, status flows and rules, and draws it as a product map you can open down to a single rule. Because the model is updated on every push, the diagram stays current — and the same model answers questions, shows what a change reaches and gives coding agents their context.
What each kind shows, and how long it stays true
| Kind | What it shows | How it stays current |
|---|---|---|
| Drawn by hand | Boxes and arrows as somebody understood the system | It does not — every change after the drawing makes it a little less true |
| Dependency graph | Imports and calls between files and modules | Regenerated from code, but it shows how the code is wired, not what the product does |
| Product map from GitMir | Areas, screens, API routes, records, customer paths, status flows, rules and how they connect | Rebuilt from the repository on every push |
Open-source products, read in full
Each row is a published GitMir model. Open the architecture page to see the areas, paths and rules behind the numbers.

The same drawing answers four jobs
Onboarding
Find where a feature lives and what it touches without a tour from whoever is free. On the projects GitMir has run, the time to a first accepted change went from 21 days to 4 days.
Planning a change
Open the area, follow its connections and see what a change reaches before anyone estimates it.
Migration
Know what depends on what before you move it — including the connections no import shows.
Review
Changes shows the drawing at any commit: what appeared, what was removed and what changed.
The diagram is one view of the model
GitMir Intelligence
Connect a repository and get the product map, answers about it and change impact — current with every push.
Public models
Eight open-source products drawn from their code, open to anyone with no account.
GitMir Business Review
What each push changed in the product, computed from two versions of the same model.
Asked about architecture diagram from code
Connect the repository to GitMir. It reads the code into a model of the product and draws the areas, screens, API routes, records, customer paths, status flows and rules, with the connections between them, as a map you can open down to one rule.
TypeScript, JavaScript, Python, Ruby, Go, Java, Kotlin, C#, Swift, PHP, Rust and Dart, plus Vue, Svelte and Astro files. It reads repositories from GitHub, GitLab and Bitbucket.
A dependency graph connects files and symbols and answers where something is used. A product map connects rules, customer paths, status flows and features and answers what the product does and what a change reaches.
Yes. Every push to the connected branch is read, and only what the push touched is read again; the drawing and every answer name the commit they are current to.
Yes. Eight open-source products, Supabase Studio among them, are modelled in public at gitmir.com/models, each with an architecture page.
