ethui

The toolkit provides a native macOS desktop environment for Ethereum development, integrating directly with local testing frameworks such as Anvil and Forge. By scanning compilation artifacts it generates an interactive contract explorer, allowing developers to call functions and view state without leaving the application. It also manages multiple wallets and can connect websites to different chains simultaneously, eliminating the need for separate browser profiles.

Designed for Web3 developers, the app emphasizes fast feedback loops by bypassing manual transaction reviews, which streamlines iterative testing and debugging. Its local‑first architecture ensures that all operations run on the developer’s machine, offering reproducible environments and reducing reliance on external services.

The software is open‑source and positioned as a stable, high‑performance solution for anyone building, testing, or interacting with Ethereum smart contracts on macOS, particularly those who use Hardhat or Foundry workflows.
