Probably. GPL "infects" code that's linked to it, so a GPL'd library can only be used in GPL'd programs. A GPL'd text editor doesn't "infect" source code, of course. A GPL'd runtime probably infects the applications that depend on it, but might not if apps can run without linking directly to it.
If you care a lot about GPL infection, this is a problem AGPL addresses; by the logic of the AGPL, even just using your code on a server as part of an ensemble in a SAAS app triggers infection. AGPL can be a reasonable choice, but people will grump about it, because it means it can't be used in commercial SAAS apps.
