Welcome to the Foundry organization.
Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.
You can install Foundry on any platform in seconds via:
curl -L https://foundry.paradigm.xyz | bash
Then, in a new terminal run: foundryup.
That's it! If everything goes well, you will now have four binaries at your disposal: forge, cast, anvil, and chisel.
See the Foundry Docs for more.
Foundry development is spearheaded by Paradigm and the Rust Ethereum open-source community.
