Guide for Operators

This guide is for people who run a measurement database — deploying modernGraphTool, adding measurements to it, and making the page their own. If you’re browsing someone else’s database, the Guide for Users is the one you want.

A new database takes four steps, in this order:

1. Choose a deployment — GitHub Pages, CDN, a pre-built release, or a source build. Each option has its own setup page.
2. Prepare your measurements — export FR data in the plain .txt format modernGraphTool reads. Skip this if you already have CrinGraph data.
3. Add them to the database — the data/ folder layout and phone_book.json, which lists every device and its variants.
4. Customize the page — page metadata, theme.css, and every config.js option.

The Config Editor, phone_book.json Editor and Theme Generator let you build those three files visually instead of editing them by hand.

Already running a database?

• On modernGraphTool v1 — see What’s New in v2, then Migrating from v1 to v2.
• On CrinGraph or one of its forks — see Migrating from CrinGraph. To run both tools side by side instead, see Dual-Hosting with CrinGraph.
