ZeSync

ZeSync Inc enables any developer to create secure, frictionless authentication and user journeys for any application. Put simply, it is about making developers faster with better editors, debuggers and workflows.

It makes the most sense for software teams. They also list Developer Platform, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

ZeSync is based in California, Maryland. More on zesync.com.

Things worth asking about: language support, team features, and privacy of your code. Get the renewal terms in writing before the first invoice.

If you have worked with ZeSync, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
