I just found this rather new project:
pdfdraw: PDF annotations for Nextcloud https://github.com/strukturag/pdfdraw
It seems it's a nextcloud addon and a separate server, and the addon communicates with the server via a yet undocumented api. So it's not nextcloud only, it could be integrated to other webservices as well.
Not cross platform (Windows only), but Sumatra PDF just got support for pdf annotations:
The UI of annotations is not really polished yet, but it's usable.
About Sumatra:
Based on MuPDF
GPLv3
UI is really small, so more screen space for content.
Extremely responsive, compared to commercial alternatives (but maybe it's mupdf achievement ) even on huge pdfs
@infeeeee that's great to see, and in fact mupdf already have those annotations... but the problem is not really with those types of annotations, it's about a few specific ones like measurement, measurement calibration, polygonal areas and perimeter measurement.
@Moult so I was a bit offtopic. Do we have a wiki page where we collect and compare the pdf viewers and and annotators? Or these should be added to the AEC Free Software directory?

I love sumatra pdf. It's my main reader on Windows and it has been for a long time. Far superior (speed) to mupdf on linux and to any pdf reader I have tried so far. So no it's not mupdf achievment. They did a lot of platform specific optimisation. That's why it's not cross platform. I didn't know about the new annotation feature.

Foxit has a strong annotation and measurement tool. It is cross platform but is freemium not open source.
Lately I have playedwith Drawboard a bit. It is proprietary and thus windows only too, but has some great tools to work with tablet computer. Very interesting if you out on building site and do some messurements.
@theoryshaw they all got a thumbs up from me - everyone else please do the same. We have earlier agreed this is quite an important tool without a good FLOSS solution.

A note that I've finally reached out to Okular and Evince - hopefully something comes out of it!

Hello,
Several tools seem to use the XFDF format to annotate PDFs:

Projectwise 365 de Bentley : "When you add markup to a PDF, your markup is stored in a separate XFDF document that gets created automatically and sits along side the original PDF document in ProjectWise (the original PDF is never modified)."

@Opus do you know any free software which uses XFDF?

@infeeeee sorry, just really keen on getting measurement annotations :) I think it makes sense in the wiki directory.

Perhaps put a +1 on the following issue: https://gitlab.com/MeldCE/first-draft/-/issues/172
Is my favorite web-based real time markup tool.
or a +1 here, https://gitlab.com/MeldCE/first-draft/-/issues/162, regarding importing/exporting pdfs.
or... XFDF portability: https://gitlab.com/MeldCE/first-draft/-/issues/171
