+Historical inventory of collaborative editors
+======
+A quick inventory of major collaborative editor efforts, in chronological order.
+
+As with any such list, it must start with an honorable mention to [the mother of all demos][25] during which [Doug Engelbart][26] presented what is basically an exhaustive list of all possible software written since 1968\. This includes not only a collaborative editor, but graphics, programming and math editor.
+
+Everything else after that demo is just a slower implementation to compensate for the acceleration of hardware.
+
+> Software gets slower faster than hardware gets faster. - Wirth's law
+
+So without further ado, here is the list of notable collaborative editors that I could find. By "notable" i mean that they introduce a notable feature or implementation detail.
+
+   
+| Project | Date | Platform | Notes |
+| --- | --- | --- | --- |
+| [SubEthaEdit][1] | 2003-2015? | Mac-only | first collaborative, real-time, multi-cursor editor I could find. [reverse-engineering attempt in Emacs][2] |
+| [DocSynch][3] | 2004-2007 | ? | built on top of IRC 
+![(!)](https://anarc.at/smileys/idea.png)
+ |
+| [Gobby][4] | 2005-now | C, multi-platform | first open, solid and reliable implementation. still around! protocol ("[libinfinoted][5]") notoriously hard to port to other editors (e.g. [Rudel][6] failed to implement this in Emacs. 0.7 release in jan 2017 adds possible python bindings that might improve this. Interesting plugins: autosave to disk. |
+| [moonedit][7] | 2005-2008? | ? | Original website died. Other user's cursors visible and emulated keystrokes noises. Calculator and music sequencer. |
+| [synchroedit][8] | 2006-2007 | ? | First web app. |
+| [Etherpad][9] | 2008-now | Web | First solid webapp. Originally developped as a heavy Java app in 2008, acquired and opensourced by google in 2009, then rewritten in Node.js in 2011\. Widely used. |
+| [CRDT][10] | 2011 | Specification | Standard for replicating a document's datastructure among different computers reliably. |
+| [Operational transform][11] | 2013 | Specification | Similar to CRDT, yet, well, different. |
+| [Floobits][12] | 2013-now | ? | Commercial, but opensource plugins for different editors |
+| [HackMD][13] | 2015-now | ? | Commercial but [opensource][14]. Inspired by hackpad, which was bought up by Dropbox. |
+| [Cryptpad][15] | 2016-now | web? | spin-off of xwiki. encrypted, "zero-knowledge" on server |
+| [Prosemirror][16] | 2016-now | Web, Node.JS | "Tries to bridge the gap between Markdown text editing and classical WYSIWYG editors." Not really an editor, but something that can be used to build one. |
+| [Qill][17] | 2013-now | Web, Node.JS | Rich text editor, also javascript. Not sure it is really collaborative. |
+| [Nextcloud][18] | 2017-now | Web | Some sort of Google docs equivalent |
+| [Teletype][19] | 2017-now | WebRTC, Node.JS | For the GitHub's [Atom editor][20], introduces "portal" idea that makes guests follow what the host is doing across multiple docs. p2p with webRTC after visit to introduction server, CRDT based. |
+| [Tandem][21] | 2018-now | Node.JS? | Plugins for atom, vim, neovim, sublime... uses a relay to setup p2p connexions CRDT based. [Dubious license issues][22] were resolved thanks to the involvement of Debian developers, which makes it a promising standard to follow in the future. |
