Intuitive, efficient, and secure smart contracts
Marlowe offers developers a set of open source tools to easily create, verify, and deploy secure smart contracts on Cardano. Now more accessible than ever, code in JavaScript and Haskell, or use Blockly for a low-code, visual solution.
Why Marlowe?
Simplified development, straightforward execution
Marlowe’s comprehensive set of tools is designed to empower developers to easily design, validate, and deploy smart contracts regardless of their expertise in software development.
Marlowe will continue to evolve, with community-built tooling a key part of its future.

Frequently asked questions
Yes, Marlowe is available to run on mainnet today. You can do this by installing Marlowe Runtime and connecting it to the mainnet.
Marlowe is also available on pre-production and preview testing environments. You may want to test your Marlowe contracts on pre-production and preview networks before running them on mainnet.
Both the pre-production and preview networks are useful for prototyping and previewing.
The pre-production network is very close to mainnet in terms of its protocol parameters and versions. Use this network for staging and testing your contracts in a real-world environment before deploying to mainnet.
The preview network is more of a development environment. It can be used for early prototyping, experimenting and learning.
