A powerful text editor – on your own or together with friends. Introductory price! The app that started the collaborative editing revolution is back with a brand-new interface, ready for the future. Write articles, code, notes or meeting minutes with friends – wherever they are.

SubEthaEdit kickstarted collaborative editing with its immediate and easy way to connect and work on text. In 2003, it won an Apple Design Award for its intuitive interface: Just add your co-workers to the document and start typing. SubEthaEdit can work without any Internet connection. Rendezvous networking makes it easy to just collaborate without the hassle of setting up connections and jumping through hoops to see each other. No complicated setup, browser or Internet required.

Of course SubEthaEdit also supports collaboration over the Internet. Send invites via iMessage or Email via Mac OS X's sharing services. The app takes care of the complicated stuff like mapping network ports in your router and making the document available, leaving you able to concentrate on what matters: Your text.

Ratings and Reviews

The last version was the first I paid for

Ryan Faerman

I own a license to the previous version of SubEthaEdit; it was a great editor. When I used it, having one file per window was the way to go as most of the work I did was live-edited on a development server. Things have changed alot since then and now I’m used to being able to open an entire project within my editor and quickly change between files; this is one of the major features that SubEthaEdit is missing.

The overall application doesn’t really look like anything of significance has changed since the previous version. I can’t really use any of the great themes that have come out in recent years (like solarized) and changing the editing fonts doesn’t quite work right.

It may be able to collaborate just fine, but if it doesn’t excel at editing alone, it’s really hard to justify the expense. This is especially true since I need my team members and friends to also use the same editor for the colloborative editing to work at all.

I would return this if I could and if I could have downloaded a demo I never would have purchased this to begin with. I expected just a little bit more to be worth the price.

Single Purpose Tool


If you are looking for a text editor with very few bells and whistles, this is it. I live in a world where I regulary use three text editors and this is one of them. I have used SubEthaEdit since the time it was “free” and have paid for it a couple of times now. I do not use it for collboration, I use its Block Edit functionality. I can honestly say that the time this one feature has saved me over the years is well worth the money I spent. My one complaint about this product is the lack of documentation. I am sure that there are gems hidden under the covers, but frankly the documentation is non-existent.

Great product, but there’s a bug in this version

I’ve been using this editor for many years and am happy to see it back in active development.

There’s a small bug when using regular expression search with windows line endings. It doesn’t count the \r character as part of the line ending. So if you want to find all the lines ending in ‘a’ for instance, you would need to search for ‘a\r$’ as opposed to ‘a$’ if the file uses windows line endings.
