But mypy&rsquo;s Python-based implementation has always struggled with performance on large codebases. <strong>Ty</strong> is Astral&rsquo;s answer to this problem: a Python type checker and language server written entirely in Rust, designed to be 10 to 60 times faster than existing alternatives.</p> <p>Astral, the company behind the incredibly popular Ruff linter, has applied the same Rust-powered performance philosophy to type checking. Ty builds on Astral&rsquo;s deep experience with Python tooling in Rust, leveraging the same multi-threaded architecture and incremental computation patterns that made Ruff the industry standard for Python linting.</p>
