Which OTRS versions are supported?
OTRS 6, OTRS Community Edition (Centuran fork) and Znuny. Selectors target the agent interface — dashboard, ticket overview, article view, compose form, dialogs.
Does it send anything to a server?
No. The extension only injects CSS into the host you explicitly enable. No analytics, no remote config, no telemetry.
Is it really free?
Yes. It has been free since 2023 and will stay that way. If you want to send a coffee my way, the link in the popup goes to a Stripe pay-what-you-want page — completely optional.
