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.

OpenPGP RainLoop Snappy RL gzip SM gzip RL brotli SM brotli
openpgp.min.js 330.742 539.988 102.388 167.371 84.241 137.413
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.
