PGP

RainLoop uses the old OpenPGP.js v2 SnappyMail v2.12 uses OpenPGP.js v5, GnuPG and Mailvelope. SnappyMail is able to use and generate ECDSA and EDDSA keys, where RainLoop does not.

Since SnappyMail tries to achieve the best mobile experience, it forked OpenPGP.js to strip it down.

remove all unused Node.js
remove all old browsers support See https://github.com/the-djmaze/openpgpjs for development

OpenPGP	RainLoop	Snappy	RL gzip	SM gzip	RL brotli	SM brotli
openpgp.min.js	330.742	539.257	102.388	166.998	84.241	137.186
openpgp.worker	1.499		824		695

Squire vs CKEditor

The Squire implementation is not 100% compatible yet, but it shows the massive overhead of CKEditor.

Still TODO:

support for tables (really needed?!?)
support BIDI (really needed?!?)

	normal	min	gzip	min gzip
squire	122.321	41.906	31.867	14.330
ckeditor	?	520.035	?	155.916

CKEditor including the 7 asset requests (css,language,plugins,icons) is 633.46 KB / 180.47 KB (gzip).

To use the old CKEditor, you must install the plugin.
