It provides full support for Solidity (\u22650.4.22) and Vyper (\u22650.1.0-beta.16) contracts, integrating with pytest for unit and integration testing, hypothesis for property-based testing, and offering built-in debugging tools with Python-style tracebacks and custom error reporting. The framework includes a console for interactive project exploration and trace-based coverage evaluation.\n\nThe package depends on 83 runtime libraries spanning Ethereum utilities (eth-account, eth-abi, eth-keys), async networking (aiohttp, aiohappyeyeballs), and cryptographic primitives (ckzg, eip712). Installation is straightforward via pip or pipx, though the large dependency tree creates medium friction. Critically, the project description states Brownie is no longer actively maintained and recommends Ape Framework as an alternative for new work.","worth_installing":"Yes-with-conditions. Brownie is stable, well-documented, and suitable for Ethereum smart contract development if you are maintaining an existing project or learning EVM development. However, the project's stated lack of active maintenance and explicit recommendation to migrate to Ape Framework means new projects should strongly consider Ape instead. Install only if you have a specific reason to use Brownie (legacy codebase, team familiarity, or learning purposes) and are comfortable with infrequent updates."},"id":"eth-brownie","links":{"html":"https://skillfed.io/packages/eth-brownie","md":"https://skillfed.io/packages/eth-brownie.md","pypi":"https://pypi.org/project/eth-brownie/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-21","license_spdx":null,"license_treatment":"permissive","name":"eth-brownie","python_support":"supports_current","summary":"A Python framework for Ethereum smart contract deployment, testing and interaction."},"popularity":{"monthly_downloads":98035,"position":13113,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.22.2"}
