## Numbers

- 16,652 stars — checked on GitHub 2026-09-19 22:57 UTC
- 7-day +6 observed via GH Archive (as of 2026-09-19 18:00 UTC)
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.

## TESIGN TAKE

The diagram earns its place because each box opens the actual file. On an unfamiliar repository it saves the first few minutes of deciding where to start reading.

## WHY IT MATTERS

Opening someone else’s repository shows folder names, not how the parts fit. GitDiagram reads the file tree and the README and draws a system-level graph instead of a folder chart. You can also just swap "hub" for "diagram" in a GitHub URL.

## BUILD FROM THIS

- Next.js 16, React 19 and TypeScript, with the graph drawn in Mermaid. Clicking a component opens the real file or directory on GitHub, and you can copy the Mermaid source or download a PNG. Private repositories work with a token held in your browser, stored separately. Generation uses OpenAI by default, with OpenRouter available for self-hosted deployments.

## WHO IT'S FOR

- People opening an open-source project for the first time, developers inheriting a codebase, and new joiners finding their way around.

## START IN 5 MINUTES

```
# Paste a repository URL at gitdiagram.com, or replace "hub" with "diagram" in the GitHub URL you are already looking at.
```

## CAVEATS

- The diagram is an AI’s reading of the code and can be wrong. The hosted service meters usage, and self-hosting needs your own OpenAI or OpenRouter key.

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
