TLDR: Nerve is a tool that helps developers write and maintain integrations. It does the same thing as a Unified API, but in a different way. Unified API companies are great but they take a lot of manual effort, which can make it hard for them to provide adequate coverage. Nerve is a Schema Network, which is a network where the nodes are apps and the edges are integrations. The idea is that you can auto-derive integrations between any two apps that have a path between them in the network. Nerve is designed to leverage the point-to-point integrations people are already writing on their own; the lack of a central bottleneck means it can provide much better coverage than a Unified API.
