# Networks

Filecoin operates several networks for different purposes. Use Mainnet for production, Calibration for testing, or spin up a local testnet for development.

## Table of contents

* [Mainnet](/networks-and-tools/networks/mainnet.md) — the production Filecoin network with real FIL and storage deals
* [Calibration](/networks-and-tools/networks/calibration.md) — the primary testnet that mirrors Mainnet parameters
* [Local testnet](/networks-and-tools/networks/local-testnet.md) — a private network for local development and experimentation
* [Legacy networks](/networks-and-tools/networks/legacy-networks.md) — deprecated networks that are no longer active
