Amplitude Experiment Overview
Welcome to Amplitude Experiment. This page acts as a quick reference as well as a high level system overview of Experiment's end-to-end feature-flagging and experimentation platform.

Guide to getting started developing for Amplitude Experiment.
- Create a deployment
- Create and configure a feature flag
- Fetch variants for a user
- Track an exposure event
Client-side SDKs work in a single-user context. Server-side SDKs work in a multi-user context.
|Evaluation API||Evaluate a user for the feature flags and experiments assigned to the deployment used to authorize the request|
|Management API (Beta)||Manage or list flags and experiments within your organization.|
When it comes to feature flag delivery and experimentation, one size does not fit all. Amplitude Experiment is built for flexibility to fit in with any architecture and a variety of needs.
Easiest way to get started delivering flag and experimenting on your client side application.
Client-side experimentation and feature-flagging involves the client making a request to fetch flags and experiments from Amplitude's remote evaluation servers when the application is initialized.
Simple and flexible API & SDKs made to fit into any system.
Server-side remote evaluation involves making a request from your server to Amplitude Experiment's evaluation servers to fetch variants for a user. Use the resulting variants directly on the server or passed back for use on the client (or any other part of your system).
Fast evaluation for performance minded systems.
Server-side local evaluation runs evaluation logic on your server, saving you the overhead incurred by making a network request per user evaluation. The sub-millisecond evaluation is perfect for latency-minded systems which need to be performant at scale. However, because evaluation happens outside of Amplitude, advanced targeting and identity resolution powered by Amplitude Analytics isn't possible.
