Nebula is a scalable overlay networking tool with a focus on performance, simplicity and security. It lets you seamlessly connect computers anywhere in the world. It can be used to connect a small number of devices, but is also able to connect tens of thousands of devices. Nebula incorporates a number of existing concepts like encryption, security groups, certificates, and tunneling, and each of those individual pieces existed before Nebula in various forms. What makes Nebula different to existing offerings is that it brings all of these ideas together, resulting in a sum that is greater than its individual parts.

The clearest difference is rating: Mobile Nebula at 4.5 against AuthPass's 3.8. AuthPass's advantage is update cadence (every 10 days vs every 2 months) and iOS requirement (12.0 vs 14.0). On price, review sentiment, ratings volume and ads there is nothing between them.
