I want to use syncthing with devices that rarely are online at the same time. I thought maybe I could simultaneously run it on a raspberry pi (or similar) with an ssd attached, which would always be on and bridge that gap.

Is this reasonable, and what specific hardware would you recommend?

It's my first project of this kind, so I thought I'd get some second opinions before buying the hardware.

Browser: Waterfox (Mozilla-based)
Add-ons in question: NoScript and maybe some Dark Reader
Cause: Adjusting these add-ons' individual website settings on the local computer
Issue: Syncing the add-on adjustments across all computers

I read that the best way to do this is to sync the entire Waterfox (Firefox) profile. Would this work, or has anyone else successfully done this? I've been using Meld to painfully, manually merge export files into a master that I then import back into each PC on a roughly monthly basis, and I feel like there's just gotta be a simpler way to sync 'em up.

We're using Syncthing with my colleague for work. Files range from few KB to around 5GB. When we just setup the system and I had 1gigabit connection, it seemed faster than server options, because you don't wait for a file to load to a server and then download from there. But I moved and only have below 100mbps atm and somehow sending a file through Telegram is many times faster than waiting for Syncthing.

Can you guys give me some pointers on where to look and which parts of documentation might be relevant for me to check to optimize for speed?

Distance shouldn't be much of a factor, I moved from +5 timezone to +6 in relation to my colleague's location.

I haven't found a focused guide on Syncthing for android handhelds, in particular for save synchronization, so I decided to make one myself.
(and also so that I don't have to paste the same txt file on discord every time a buddy asks for directions)

Tell me what you think

I tried to install a Crucial DDR4-3200 8GB on my DS220+ without success, any one succeeded?

I ended up trying Syncthing to be my "dropbox" equivilent between my ZimaOS server and my various computers.

I followed the Zima guide for it (https://www.zimaspace.com/docs/zimaos/app-store/syncthing-install) exactly.

But when I tried to run the app it started with "Starting Up, Please Wait..."

then later "Service Unavailable."

I checked the logs and it ended up saying this over and over:

syncthing | \[start\] 2026/10/16 00:53:40 INFO: Generating ECDSA key and certificate for syncthing...

syncthing | \[start\] 2026/10/16 00:53:40 WARNING: Failed to load/generate certificate: save cert: open /config/cert.pem: permission denied

Not sure what I did wrong, or what I missed....

What the title says. I use syncthing-fork on my android (running android 14) and the files go from the PC to the android no problem, but they never go from the android to the PC. I've checked that the settings are right, there are no restrictions and it ignores permissions, but nothing has worked. I've even tried moving both folders and redoing the folder setup but nothing. IDs are fine, no errors or sync erros, no extra files. Everything should work but it doesn't. Any ideas?

which one is better or more safe?

Hi guys, I am using the ever lasting trick for unlimited storage, and I am running constantly into one issue: Pixel 1 has only 32 GB of storage, and despite me running backup in syncthing on weekly basis, phone runs out of storage and 30 day cleanup that Google includes is not fast enough to mitigate these problems.

Has anyone figured out how to detect that photos are backed up to Google Photos so that Syncthing can be triggered again to continue?

BasicSync, Syncthing-fork, or Syncthing in Termux?

I have been using synctrayzor for 5 years now with no issues. Now im having issues haha

My windows 10 (Purple_pc) is sharing a folder with 2 remote devices:

1.Dumpster Pc (found this pc in the dumpster and it works great. Angry mom at her kid who wouldnt help around the house threw it out) 2. MSI Laptop

Both the dumpster pc and MSI laptop have been off for a week or 2.

Purple Pc had 155GB of files according to the synctrayzor output.

Dumpster PC had 183 GB, becasue i deleted 30GB on Purple PC over the week while the Dumpster PC was off.

Turned on laptop to at least get it up to the 155GB, it updated fine as it was only missing 1.25GB. Turned off laptop.

turned on Dumpster PC next. left laptop off. Dumpster PC says it is up todat with the 183, and Purple PC says up to date with 155GB… nothing is being transfered BUT the GUI showed that remote device was 30GB out of sync… nothing ever synced over night. so i removed the dumpster pc remote device from purple pc, and visa verca on dumpster.

FINALLY, after re-adding dumpster, synctrayzor decided that Dumpster was the most up to date machine add gave purple pc the extra 30GB i had deleted last week.

ok, thats fine. Purple PC is now 186Gb and mathcing dumpster… i turn on laptop and it wont sync. it says it has 12k files and 30GB out of sync, but both purple and laptop say up to date. I restarted both and no transfer. Had to delete the devices again and redo the entire setup, now im stuck for 12 hours re scanning the drives…

why is syncthing not synching correctly? I used to be able to have dumpster pc off for MONTHS and it would update just fine with synctrayzor. Now i am having to redo all the paths and sharing.

thanks

I have this sync that on one of the 3 devices synced is showed as not synced. But really it is, if I create a file, it's synced, if I delete one it is as well, I don't see any conflict, etc.

Why makes it so that a share is marked as not synced ?

Thanks !

I've been syncing my vaults between my Mac and my Windows PC, plus one vault I share with a friend. Obsidian Sync felt like a lot to pay for that, and plain Syncthing kept giving me conflicts on workspace.json and plugin settings. So I ended up building my own thing on top of Syncthing and calling it Mortise.

It's a small app that sits in the menu bar / tray. One machine acts as the hub: in my case a cheap VPS, but it can also be one of your own computers. Everything syncs through it. On the VPS the vaults are end-to-end encrypted, so the server can't read anything. To share a vault I just send my friend an invite code; he pastes it and that's it.

I also added the Obsidian-specific stuff that annoyed me: it skips workspace files, everyone gets their own settings folder so themes and plugins don't fight, conflicts show up side by side, and deleted notes can be brought back for 30 days. The shared vault lives as a "Shared" folder inside my personal vault.

I am also thinking about building my life tracker template (that you kind of see in the screenshot) into Mortise. When you create a vault, you'd pick the modules you care about (habits, journal, tasks, workouts and so on) and start with a ready-made vault that already syncs.

It's still early and the code is private for now. If people are interested I'll clean it up and open the repo.

Curious what you guys think.

Is there some way to only sync things via some sort of button? Without automation? For example, if I finished playing X on my PC, I'd have to open syncthing and click "Upload" to have it sync, then go to my android device and click "Download", to play X on a different device. If not, are there alternatives?

Whenever im using syncthing, my antivirus flags it as trojan. Is it really malicious or its just that the anti virus misunderstands it

what am i getting wrong ? my source folder is set to send only and has 2 files and the destination is send + receive and is an empty folder, why is syncthing not copying the files from source to destination

EDIT: [SOLVED]

ok i got this fixed, this was the solution, removing folders from syncthing, deleting .stfolder & .tmp files and re-adding folders did it!

Newbie here:

I keep getting this popup after I installed synctrain on my ios and made it work with my computer in order to sync Obsidian. How do I get rid of it?

I have two Mac computers, I synced my Desktop and Documents folders and it worked very well.

Now, the Documents folder is 'out of sync' on both sides. I tried to stop sharing on one computer, and re-established the sharing. To no avail.

The sharing is with default settings, both directions etc...

Is there a way to re-establish syncing?

I work on a desktop and a laptop. Claude Desktop keeps every Code-tab conversation on the machine where it started, so I'd have a long session going on one computer and nothing on the other.

Syncing ~/.claude with Dropbox/Syncthing doesn't fix it: Claude Desktop lists conversations from its own per-machine records, so copied transcripts never show up in the sidebar. Worse, just opening a conversation (or rewinding it) rewrites the files, so naive file sync happily overwrites your newer messages with a stale copy. I lost work to exactly that.

So I made ClaudeSync, a small Windows tray app:

• moves the transcript and Claude Desktop's own record, so the conversation shows up in the other machine's sidebar and you just keep typing
• compares message ids instead of file bytes, and follows conversations across rewinds
• never silently overwrites: if both sides continued, you pick which to keep; everything is backed up first
• different project paths on each machine are fine

It runs on your own free Supabase + Cloudflare account (about 15 minutes to set up), so nobody else holds your conversations. It moves conversations, not code, so I recommend Syncthing for the project folders.

Hi,

Has anyone used PySN to auto-sync files in pc with any citation-database software. Could it work?

Thanks

If I disable location, syncthing stops syncing and won't let me use the app. Why does it need my location all the time to transfer files? There a way to disable location and have it still work?

Hello Just downloaded the latest version via the github link for the windows installer and scanned it with the enclosed website...are they false positives?
