After 2 years of hard work, we've created something that's indistinguishable from a Google Chrome that runs at 4K, 60 frames a second, takes no more than 500 MB of RAM, and often less than 30% CPU with 50+ tabs open. This is the first step in making a new kind of computer.
If you're not sure what that means, imagine your browser is a Netflix video but running on cutting-edge server hardware somewhere else.
When you switch to Mighty, it will feel like you went out and bought a new computer with a much faster processor and much more memory. But you don't have to buy a new computer. All you have to do is download a desktop app.
To make Mighty work, we had to solve a lot of complex engineering problems, including designing a custom server to keep costs low, building a custom low-latency networking protocol, forking Chromium to integrate directly with various low-level render/encoder pipelines, and making the software interoperate with a long list of macOS features.
Lag would have been a real problem 5 years ago, but new advances since then have allowed us to eliminate nearly all of it: 5 Ghz WiFi bands, H.265 hardware-accelerated low-latency encoders, widespread 100 Mbps Internet, and cheaper, more powerful GPUs. We also designed a new low-latency network protocol, and we locate servers as close to users geographically as possible.
