Astral vs detekt

Astral makes open-source tools for Python development, including Ruff, a linter, and uv, a package and project manager. Both are written in Rust. uv brings together project management, a universal lockfile, script execution, Python version management, tool installation, workspaces and a pip-compatible interface. Astral describes that interface as providing a 10–100x speedup over pip. uv supports macOS, Linux and Windows. Its documented integrations include Docker, Jupyter, marimo, GitHub Actions, GitLab CI/CD, pre-commit, PyTorch, FastAPI, Bazel, artifact registries, Renovate, Dependabot, AWS Lambda and Coiled. Astral says its tools are permissively licensed and free forever. It describes security controls for workflows and releases, including read-only default workflow permissions, full-length commit-SHA pinning, Trusted Publishing, Sigstore attestations and immutable GitHub releases. Documentation directs users to its Discord community for support. The separate pyx package registry offers optimized installs and other package-management features, but is no longer accepting new signups. Astral has announced an agreement to join OpenAI as part of the Codex team.

detekt is a free static code analyzer for Kotlin that helps identify code smells. It supports Android, JVM, JS, Native, and Multiplatform projects, and runs on Linux, macOS, and Windows. Developers can configure rule sets, create baselines for existing issues, and suppress findings with @Suppress annotations. Reports can be generated as HTML, Markdown, SARIF, Checkstyle XML, or custom formats; complexity reports can include lines of code, cyclomatic complexity, and code smell counts. The project provides a Gradle plugin and documents use with Gradle, Maven, and Bazel builds. Its Gradle plugin requires Gradle 6.8.3 or higher. Custom rule sets can be added through detekt's RuleSetProvider and ServiceLoader pattern, and the marketplace lists community rules, extensions, and plugins. CLI installation guidance covers Homebrew on macOS, Scoop on Windows, SDKMAN on Unix-like systems, and NixOS. detekt supports autofix, IDE use, and CI. Its security policy says patches are applied up to the current minor version, with earlier versions handled case by case.
