modheader-export-backup

Export your ModHeader profiles without ModHeader.

npx @requestly/modheader-export-backup

Overview

ModHeader was pulled from the Chrome Web Store and Edge Add-ons in mid-2026, so its Export → Download JSON button is out of reach — you can't export from an extension you can't open.

Your profiles are still sitting in your browser profile on disk. This CLI reads them and writes the exact same export file ModHeader would have, which Requestly imports directly.

How to export

1. Run it

npx @requestly/modheader-export-backup

Needs Node.js 20 or newer. Nothing is installed permanently, and you can leave your browser open — nothing is written to your browser profile.

2. Pick a browser profile

It lists every browser profile on your machine that has ModHeader data. Move with the arrow keys and press enter.

Found 2 ModHeader backups. Which one?

  BROWSER  BROWSER PROFILE  MODHEADER PROFILES IN IT
❯ chrome   Testing          2 profiles: Profile 1, Profile 2
  edge     Person 2         1 profile: Profile 1
  Quit

up/down move · enter select · esc cancel

One row per browser profile: which browser, which of that browser's profiles, and what ModHeader has stored in it.

3. Choose where to save it

Press enter for ~/Downloads, or type another folder.

Export to [/Users/you/Downloads]

It writes modheader-<browser-<profile.json and returns to the list with that row marked ✓ exported, so you can repeat steps 2–3 for your other profiles. Choose Done when you have them all.
