Is Open Prompt Manager safe?

Low risk

Open Prompt Manager places saved prompt titles, contents, and tags into the page DOM on permitted sites.

When Open Prompt Manager loads on a permitted AI provider or custom site, it reads the user's saved prompts from local extension storage and builds an in-page prompt list. Each prompt list item includes the prompt title, content, and tags in DOM data attributes, so scripts running on that page can read the saved prompt library while the UI is present.

Shared hosts - 1 hostname

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.
