The user is asking about a wiki software that uses HTTP GET requests for edits (as opposed to the more standard POST method for modifying data).
Let me think about this carefully. Using GET for edits is unusual and generally considered a security concern (CSRF) and violates REST semantics. However, there are some wikis that historically or by design use GET for edits.
Let me think...
MoinMoin - I believe MoinMoin uses POST for edits.
MediaWiki (Wikipedia) - Uses POST for edits.
Wiki.js - Modern, uses POST.
TiddlyWiki - It's a single-file wiki, client-side, so it doesn't really use HTTP in the traditional sense.
DokuWiki - Uses POST for edits.
Wait, let me think about older or simpler wikis...
Actually, I recall that MoinMoin in some very old versions might have used GET for certain actions, but I'm not confident.
What about UseModWiki? It was one of the earliest wikis. Let me think... UseModWiki was very simple. I believe it might have used GET for some operations given its simplicity.
Actually, I'm thinking of Wiki by Ward Cunningham (the original wiki). The original wiki was extremely simple and I believe it used GET requests for edits - you would click a link and the edit would happen via a URL change. But I'm not 100% certain about this.
Let me also think about Wikkli - a very simple PHP wiki. I think it might use GET for edits since it's very minimal.
Actually, I recall that some very early/simple wikis used GET for edits because they were built before POST forms were common or for simplicity. The original Wiki (WikiWikiWeb) by Ward Cunningham - I think the edit was done by appending to the URL.
Hmm, let me also consider TiddlyWiki - but that's local.
I think the most notable example would be the original Wiki (WikiWikiWeb) or possibly UseModWiki. But I'm not 100% certain about the exact HTTP method they used.
Actually, wait - I recall that MoinMoin had a period where it supported editing via GET URLs for convenience (like ?action=edit&...), but the actual submission was POST.
Let me think about this differently. The user is asking specifically about a wiki that uses GET for edits. This is a specific technical detail. I should be honest about what I know and don't know.
I believe the answer they might be looking for could be:
The original WikiWikiWeb by Ward Cunningham
Wikkli (a very simple PHP wiki)
Some other minimal wiki
Actually, I'm not fully confident in my specific knowledge here. Let me think if there's a well-known example...
I think I should mention that using GET for state-changing operations is generally discouraged (violates idempotency, vulnerable to CSRF, can be cached by browsers/proxies), but acknowledge that some early or minimal wikis did this. I'll mention candidates I can think of while being transparent about my uncertainty.
Hmm, actually - could they be thinking of TiddlyWiki? No, that's a single HTML file.
What about Wiki.js? No, that uses REST with POST/PUT.
I think the most likely answer is either the original WikiWikiWeb or a very simple early wiki. Let me go with what I can reasonably suggest while being honest about uncertainty.
This is a bit of a niche question, and I want to be upfront that my confidence on the exact HTTP verb used by some very early wikis is limited.
A few candidates:
WikiWikiWeb (the original wiki by Ward Cunningham, ~1995) and its early descendants were extremely simple. Given their minimal architecture, I believe some of them performed edits via GET URLs (e.g., appending the new page content to a query string) before the broader web community settled on POST for state-changing operations.
Wikkli, a deliberately tiny single-file PHP wiki, is the kind of minimal implementation where a GET-based edit is plausible.
Some UseModWiki forks/early versions had a similarly minimal request model.
That said, I'm not 100% certain which specific one you have in mind. Using GET for a state-changing action like an edit is unusual because:
It violates the idempotency expectation of GET.
Browsers and proxies may cache the response.
It's vulnerable to CSRF (a crafted link in an email can "edit" a page when clicked).
URL length limits can truncate the edited content.
For that reason, essentially every modern wiki (MediaWiki, MoinMoin, DokuWiki, Wiki.js, etc.) uses POST (or PUT in REST-style APIs) for the actual save.
Do you have a more specific context — a version, a language, or a use case? That might help me pin down the exact software you're thinking of.

You tell me if it's right. That's just what the model speculates when being asked "Do you know a wiki software that uses GET for edits?"
