Particle Network ships five SDKs. They’re independent, free to use, and designed to compose. Most apps pick a stack of two or more — for example, a signer (Particle Auth or Connect) plus Universal Accounts. This page helps you pick that stack. Use the flow chart to reason it out, or jump straight to your scenario below.Documentation Index
