Astral presents it as the next tool in the same high-performance Python developer-tooling line as Ruff and uv. ### Project history Astral announced ty as a beta type checker and language server after building a reputation around fast Python tooling. The official README states that ty is in beta, uses 0.0.x versioning, and does not yet promise a stable API, so its history is still early and deliberately pre-1.0. The project is developed in close relationship with Ruff: the README says development currently takes place in the Ruff repository for changes to the Rust source contained in its submodule. ### Adoption history Astral positions ty as an alternative to mypy, Pyright, and Pylance, emphasizing speed, gradual adoption, editor features, and support for partially typed code. The docs and README highlight editor integrations for VS Code, PyCharm, Neovim, and other LSP-capable clients. The Homebrew formula's presence alongside packages in apk, dnf, Nix, Arch, Scoop, Winget, and zypper reflects rapid package-manager adoption typical of Astral tools, even while ty remains beta. ### How it is used Package users run `ty check` from the CLI or use ty as a language server in editors. The README recommends `uvx ty check` for quick use, while the documentation covers installation, configuration, diagnostics, suppression comments, project support, and editor setup. ### Why package nerds care ty matters in the package-manager niche because it extends the modern Rust-for-Python-tooling pattern from Ruff and uv into static typing. For maintainers, it is another fast single-command tool that can be wired into editors, CI, pre-commit workflows, and distro packages without a bespoke Python runtime story. ### Timeline - 2025: Astral announced ty as a beta Python type checker and language server. - 2025-2026: Official docs described CLI, language-server, configuration, rule, and editor-integration workflows. - 2026: The Homebrew formula lists ty with broader cross-platform package-manager coverage. ### Related projects - Related projects include Ruff, uv, mypy, Pyright, Pylance, Pyre, and Python editor integrations that consume language-server features. ### Sources - - - - - source_facts.package-manager ## Security Notes No matching local secret-handling manifest was found for ty. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: pyproject.toml, ty.toml, ~/.config/ty/ty.toml, $XDG_CONFIG_HOME/ty/ty.toml - Windows: pyproject.toml, ty.toml, %APPDATA%\ty\ty.toml ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** ty - **Version Scheme:** 0 - **Revision:** 0 -
