Is LiChess Tools, by Siderite safe?

Clean risk

LiChess Tools uploads pasted chat and profile images from Lichess pages to imgbb.com.

When you paste or drop an image into supported Lichess chat or profile fields, LiChess Tools reads the image file and uploads it to imgbb. The extension then stores the returned image metadata locally and inserts the public image URL into the active Lichess field.

Shared hosts - 21 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
