1. Foundry
Foundry is a blazing-fast, Rust-based development toolkit that has taken the Ethereum world by storm. While often associated with Solidity, it offers excellent support for Vyper. Its main advantage is speed, as it can compile and run tests significantly
faster than JavaScript-based alternatives. With Foundry, you can write your tests in Solidity while building your core logic in Vyper, leveraging a helper contract called `VyperDeployer` to integrate the two seamlessly. This allows developers to use Foundry's powerful fuzzing and formal verification tools on their Vyper contracts, making it a top choice for security-conscious projects.
2. Hardhat
Hardhat is the go-to JavaScript-based development environment for many Ethereum developers, known for its flexibility and extensive plugin ecosystem. For Vyper developers, the `hardhat-vyper` plugin integrates the Vyper compiler directly into the Hardhat workflow. This allows you to manage both Solidity and Vyper contracts within the same project, run a local Ethereum network for testing, and write your tests and deployment scripts in JavaScript or TypeScript. Its flexibility makes it a solid, reliable choice for teams with mixed-language codebases or those who prefer working within the JavaScript ecosystem.
3. ApeWorX
ApeWorX is a modern, Python-based framework designed for developers, data scientists, and security professionals. Given that Vyper is itself Pythonic, Ape offers an incredibly natural and intuitive development experience. It features a modular plugin system, allowing you to easily add support for Vyper, different testing tools, and various blockchain networks. ApeWorX excels at project management, dependency handling, and complex scripting, making it ideal for developers who want to stay within the Python ecosystem for their entire workflow, from contract creation to off-chain data analysis.
4. Brownie
Before ApeWorX gained prominence, Brownie was the dominant Python-based framework for smart contract development and a favorite among Vyper pioneers. It provides a comprehensive suite for compiling, deploying, and testing contracts, with deep integration of the popular `pytest` testing framework. This allows for writing clean, Pythonic unit tests for your Vyper contracts. Although Brownie is no longer actively maintained and the project itself recommends users migrate to ApeWorX, its influence is undeniable, and many existing Vyper projects and tutorials are built with it.
5. Truffle
As one of the original Ethereum development suites, Truffle has a long history and a rich set of features for building decentralized applications. While its primary focus has been Solidity, it provides support for Vyper through plugins. The Truffle suite includes the Ganache local blockchain for rapid testing and Drizzle for connecting your smart contracts to a front-end interface. For developers already embedded in the Truffle ecosystem, its support for Vyper allows them to experiment with the language without having to switch their entire toolchain.
6. Titanoboa
Titanoboa is not a full-fledged framework in the same vein as Hardhat or Foundry, but rather a powerful Vyper interpreter designed for rapid testing and debugging. It was built to provide developers with detailed and readable tracebacks, making it much easier to pinpoint errors in complex contracts. Because of its focus on interpretation, it's an excellent tool for interactive development and exploration in a console environment. Frameworks like Moccasin are built on top of Titanoboa, leveraging its interpretive power for a more complete development and testing experience.
7. Remix IDE
For those who want to get started without a complex local setup, the Remix IDE is an invaluable tool. It's a powerful, browser-based integrated development environment that supports both Solidity and Vyper. With Remix, you can write, compile, deploy, and interact with your Vyper contracts directly from your web browser. It's an excellent choice for learning, quick prototyping, and debugging small-scale contracts. While larger projects typically move to a command-line framework, Remix remains the best starting point for many developers entering the smart contract space.
