Ganache for Mac

Run a local Ethereum testnet

Ganache gives developers a local blockchain instance they can run on their machine to develop, test, and deploy smart contracts quickly. It provides a simple graphical interface that keeps common tasks straightforward and speeds up iteration during dApp development. A desktop build is available for macOS.

Why developers choose it

• Fine-grained control over mining cadence and gas parameters so you can tune transaction costs and block times.
• Detailed transaction history and real-time logs for debugging contract interactions and wallet activity.
• Integrated block-inspection tools that let you browse blocks, transactions, and contract state without leaving the app.

Advanced testing capabilities

• Import existing smart contracts and state to test upgrades or reproduce specific scenarios locally.
• Fork from the Ethereum mainnet to replicate live-chain data and simulate how your contracts behave against real contract addresses and state.
• Multiple configuration options to emulate different network conditions or transaction environments for thorough QA.

Pricing and alternatives

Ganache is free to use, making it an accessible choice for solo developers, teams, and students.
Suggested alternative: Duet (free) — another lightweight local-chain tool worth trying if you want a different UI or workflow.

Getting started quickly

1. Install the macOS desktop package, launch the app, and create a new workspace.
2. Configure your desired gas and block parameters, then deploy or import contracts for testing.
3. Use the built-in logs and block viewer to step through transactions and verify behavior before deploying to a public testnet or mainnet.
