Formerly known as ZEIT, Vercel has a lot to offer in the serverless movement.
ZEIT was one of the pioneering companies at the time pushing Serverless technology. ZEIT’s first focus was to ease deployments, which resulted in the creation of Next.js.
Some of Vercel’s customers include AirBnB, Auth0, GitHub and the Washington Post.
Vercel announced a whopping $21M Series A funding early 2020.
Fastly, traditionally a CDN, was one of the first CDNs that openly and actively promoted it’s edge worker technology.
Fastly has been open and quick when it comes to adding features and functionality to their Serverless product. The platform is runs on WASM logic (with JIT compilation). All in all, one could expect very fast responses when it comes to running your application on Fastly.
Fastly has a unique online fiddler tool to experiment and try different Edge features and functionality without even having to register, live log tailing and individual end-user request trailing. A notable customer of Fastly’s Edge Compute platform is LoveHolidays.
