Introduction
One platform and one SDK per stack for analytics, errors, logs, flags, push, realtime, voice, request tracing and more — all correlated to a single user journey.
Nexus is Inverge's application platform. You add one SDK to each app or service, give it an API key, and get every product below — each one tied to the same person and the same session, so a crash, the log lines before it, the request that caused it and the replay of what the user saw are one click apart.

Each SDK page covers installation, configuration and framework integrations, and links to a complete, generated API reference of every public class, method and option — built from the SDK source, so it never drifts from what you install.
The shape of an integration
Every arrow is the same thing: an SDK (or your own HTTP client) calling the partner API with an API key that belongs to one environment. The console reads that environment back to you.
