2015 Encrypted email service ProtonMail open sources its web interface


Secure encrypted email provider ProtonMail, which runs a “zero access” PGP mail service based in Switzerland has now open sourced its webmail interface — meaning all the code that runs locally on the user’s computer is available for inspection. Earlier it open sourced its cryptography code from the get-go, it’s now letting outsiders parse its webmail client too — at the same time as launching v2 of the client. ProtonMail is hosting the source code for v2 on Github. While it’s offered its secure email for free for now, the startup will be switching monetization on this fall — with the introduction of its first paid accounts, offering additional storage and extra features for a subscription fee.
