A downloadable program for Windows, macOS, and Linux

Download NowName your own price

This page offers an offline-friendly version of Terrasavr.

Once you have launched it once (and it has synchronized files with the online version), you can run if offline and it'll continue showing the last update that it downloaded.

Note: for the same reason (syncing from site), itch files are not updated at the same time as site version is - only when changing features specific to offline UI.

If you are using a Chromium-based browser, you may also install Terrasavr as a web app much to the same effect.

If something breaks, tell me on Twitter or on Terraria forums' topic.

Can't download it I tried using Flash Player (Updated it 4 times)
tried using chrome to open but it downloaded the file again

Same as with person below - you probably need flash player projector, not just a regular one.

Okay I downloaded it and I know its compatible because my I'm using chromium and my pc is 32bit (Download the Flash Player content debugger for Opera and Chromium based applications – PPAPI)  So now how to I open the .swf file? Because every time I try opening it using chrome it redowloads Terrasavr.swf

You need the "Download the Flash Player projector" for your according platform. Not a content debugger. Not projector content debugger. Just projector. Projector is like a video player, but you give it SWF files to play.

Okay. Thank you, and sorry for being stupid

Somehow i only see  a blank screen when i open the .swf file. The flash version on website works fine though... Can you help me?

It's possible that your flash player projector is broken and/or outdated and you'd need to download a new one.

Been using this for probably more than a year, paid a small coffee i guess.. Good program.

Thank you!

I can download the game, but somehow, when I run Terrasavr.swf, this message appears.

ReferenceError: Error #1069: Property setTo not found on flash.geom.Rectangle and there is no default value.

Can you help me, in by any chance?

I think you might have to update Flash Player (or pick the newest to open files if you've got a bunch installed) - that doesn't happen unless the thing is ran through a fairly outdated (pre-2013?) one.

The download doean't work in any ways. Could you please choose another website and upload again? I really like this tool because of easement. (Thanks a lot for programming this.)

Define "doesn't work"? Alternatively you can "save as" the SWF from the website directly if you must.
