I nearly went with Syncany, they were a very close second but they are still in alpha, plus they have no mobile apps (yet). I really like being able to take a photo with my phone and have it sync to my computer.<p>Development on Seafile is very active and they are transparent about security issues. I don&#x27;t think it is poorly written but maybe a third-party audit like Truecrypt did is a good idea.<p>Here&#x27;s their &#x27;Records of security issues&#x27; page: <a href="https:&#x2F;&#x2F;seacloud.cc&#x2F;group&#x2F;3&#x2F;wiki&#x2F;security-records&#x2F;" rel="nofollow">https:&#x2F;&#x2F;seacloud.cc&#x2F;group&#x2F;3&#x2F;wiki&#x2F;security-records&#x2F;</a>
