At some point we noticed that new (and not so techy) users don't even know how DAVx5 looks/works *before* they install and start using it 😅
So … we've teamed up with a young and talented 3d artist (link below) and created a 60 sec catchy showcase video for DAVx5 😃
We hope you enjoy it!
(although most likely you already use DAVx5 and probably don't need an intro anymore 😇 ).

🚨 ALERT 🚨 for all #FOSS projects out there which get donations via PayPal.
In the last 2 days we've gotten several donations (some as "purchase") ranging from 250 → 500 USD. Always same amount as USD (which was suspicious since we rarely get USD).
The trick of the cheaters: They will open a "Paypal Buyers protection" case and if you just send back the money rather than "cancelling" the real transaction, they will get the money twice...
Suggestion: Mark it as fraud and let Paypal resolve it.

@nprofile…4krt @nprofile…wxk0 if you had push in use already, then no need to change anything.
If you're setting it up freshly then justrefresh the collections list in the davx5 account, in the details view it will then see that the server is rdy for push. a distributer for the push is automatically selected from davx5. if you want to change it you can do so in the DAVx5 settings at the bottom.

2026-06-28 14:13:51 UTC

Nextcloud folks: Do you need something to do on a hot day (like this - at least in central europe ;-))?
Why not update your dav_push app in the NC app store? @nprofile…wxk0 has included support for NC34 today, so you'll be able to instant-sync your contacts/calendars and tasks/notes/journals again with the latest version of Nextcloud 💙

DAVx5 4.5.14 is out!
Release notes: https://github.com/bitfireAT/davx5-ose/releases/tag/v4.5.14-ose
Since we had a major icalendar-processing update in 4.5.12 we've released 4.5.13 and 4.5.14 recently that should fix all occurring special edge cases which were not detected through our tests and betas.
So... if you had an issue with tasks or events please update to the new version. Most likely it will be fixed :)

@nprofile…8udl @nprofile…zgz0 Yes, we've seen that before we started with our specification years ago. But there are no official specs how this is/was implemented in the Apple universe and elsewhere. So it is more or less unusable. We are going the open way :)
Nevertheless if you have official specs for this we'll happily compare them with our WebDAV Push specs and will see if there is room for improvement.

We've just released DAVx⁵ 4.5.12 🎉 !
This version brings major upgrades to event + tasks processing (big ical4j library update).
When using WebDAV Push for instant sync there is now a nice selection view where you can control your @nprofile…amy7 distributor.
For many users DAVx5's sync was a little bit of a blackbox. We now provide more details on how many events/contacts/tasks were synced by DAVx5 and which are stored in the respective content providers.
We hope you enjoy the new version 🤘

@nprofile…wxk0 @nprofile…u9pr This has nothing to do with Nextpush. It can be activated independently to push your contacts calendars and tasks to be received by DAVx5. Just install the davpush app on Nextcloud, then refresh calendars/ address books in DAvx5 and select the UnifiedPush provider you want in the DAVx5 settings at the bottom.

@nprofile…zaq9 mhmm, https:// is used normally when the URL is written without http or https. If one needs http:// without the S then it must be written explicitly. And if https:// is in the URL it should already be handled correctly. did it appear twice like https://https:// ?

2026-02-19 11:50:35 UTC

@nprofile…wxk0 is maintaining the DAV Push extension for your @nprofile…u9pr and we're super happy that it again got day-1-support for Nextcloud 33 / Nextcloud Hub 26 Winter (released yesterday!). 🎉 🎉 🎉

@nprofile…zaq9 thanks :) Synology offers only a very basic tasks implementation. but contacts and calendars should work fine. you need to create seperate accounts for these services in DAVx5!

@nprofile…p388 That's highly unusual. Even excessive syncing of multiple accounts should barely be noticable in the battery stats. which device and which network config? Maybe try to completely remove the app and reinstall.

See you all in 2026!

@nprofile…kl7y On the server side there is a directory that stores contacts and calendars in vcard/ical format. This https://www.davx5.com/tested-with/ shows some examples. If the server is able to provide these data via the CalDAV and CardDAV protocol you can use our app to sync it down to your Android device.

While DAVx⁵ is a client-server sync tool we often get questions if there is a possibility to sync in server to server. We had a nice talk today with the creator @nprofile…uqnt from pimsync who does work on a tool that does exactly that.
Check out the project here if you're interested:
https://pimsync.whynothugo.nl/
We also added it to our FAQ: https://www.davx5.com/faq/synchronization/how-can-i-synchronize-entries-between-servers

@nprofile…p3su Even better! Do multiple VAPID keys work with "instance" in UnifiedPush.register? Is there a limit of max VAPID keys? Do we need to renew the registration?
Sorry if these things are already covered by the docs. I haven't read everything in detail yet, but trying to get an overview.

2025-02-20 19:03:02 UTC

- reply

@nprofile…p3su That's great news! We plan to implement this in DAVx⁵, too: https://github.com/bitfireAT/davx5-ose/issues/1321
Do I understand correctly that the approach for FCM w/o hosted gateway "only" works if there's only one VAPID key?
In case of multiple WebDAV-Push servers, they'd have different VAPID keys. In this case we could still provide a DAVx⁵ gateway or suggest another distributor, right?
But getting Push over FCM for the big fraction of users who only need Push for one account would absolutely be awesome!

@nprofile…295w Yes, currently this is not possible, since internally this is not just a few database entries that could be changed easily, but stored also in various places on a system level. You need to remove the account and redo the setup.

2025-01-13 16:18:06 UTC

- reply

@nprofile…ylwl Hi, currently this is not possible because it is a very complicated thing to implement. We would have done that already since it is often requested. The original user entered URL is only used during service detection, and the resulting "real" collection paths are saved inside DAVx5 but also with connections to the Android System. We are doing a lot of refactoring right now, which will make this a bit easier in the not too distant future.

2024-12-28 20:24:54 UTC

- reply

@nprofile…vg08 Does DAVx⁵ sync without errors on the CB? If yes most likely events are in the calendar storage of the CB (like they are on every Android device). They are never stored by DAVx5 itself.You can see a number of synced events in the debug info of DAVx5. If there are events > 0 then you'd need to find a calendar app that is accessing the calendar storage. Google Calendar has an option to display "third party non-Google" calendars (activate this in the settings of the Google Calendar app).

https://github.com/bitfireAT/davx5-ose/releases/tag/v4.4.5-ose
We also continued work on Push! You can now select your desired UP distributor app yourself + DAVx5 will automatically re-subscribe your collections now.
This is the last release of this year and we want to 🧡 Thank You 🧡 so much for your support!
