Scarb

Scarb is a specialized build tool and package manager designed specifically for the Cairo programming language, which is integral to the Starknet ecosystem. It serves as an essential utility for developers to manage dependencies, compile projects, and ensure workspace stability within decentralized environments.

Originally developed by software engineers at Software Mansion, a specialized software house based in Poland, the brand has grown as a foundational piece of open-source infrastructure. Its development is collaborative, involving contributions from the global developer community and stakeholders within the Starknet ecosystem.

While Software Mansion remains the primary maintainer and creator, the tool operates under an open-source license, typically Apache 2.0 or MIT, meaning it is collectively 'owned' by the community but technically managed by its original creators in Poland. It continues to be a cornerstone for ZK-STARK based development globally.
