Ruff alternatives (2026)

Ruff: One fast tool to replace your entire lint toolchain.

Its Catch: Not every rule from every tool is implemented.

Below: 5 free or free-tier tools from the same category (Python tooling), free and open source first, then the closest match by shared tags. Each keeps its own Catch.

  1. 1.uvPython packaging at Rust speed

    Free / OSS · Apache-2.0 · 90.9k GitHub stars

    VerdictFinally, Python packaging that does not waste your time.

    CatchRelatively new, so edge cases exist. Some older packages with unusual build systems may have issues.

  2. 2.HTTPXAsync HTTP client for modern Python

    Free / OSS · BSD-3-Clause · 15.6k GitHub stars

    VerdictThe requests replacement for the async era.

    CatchAnother dependency when requests works for simple cases. Some requests plugins do not have HTTPX equivalents.

  3. 3.tyMIT Astral Python type checker (beta) in Rust

    Free / OSS · OSS/MIT · 19.9k GitHub stars

    VerdictMIT Astral type checker. Fast and young — measure it on your own codebase.

    CatchBeta/maturing vs mypy/pyright — say so. Don’t assume it already replaces either tool on every codebase. Distinct from Ruff (lint/format) even though same vendor.

  4. 4.jcMIT CLI stdout→JSON so jq pipes stop parsing text

    Free / OSS · OSS/MIT · 8.7k GitHub stars

    VerdictMIT stdout→JSON. Free forever; serialize the CLI before you invent another awk field splitter.

    CatchVs jq (JSON *filter*): jc is the *ingress* that makes stdout JSON; it does not replace jq transforms. Parser coverage is wide but not infinite — unsupported commands still need custom parsing. Python/pip (or a release binary) is a dependency versus tools that ship only static Go/Rust.

  5. 5.HTTPieBSD-3-Clause human-friendly HTTP client for the terminal

    Free / OSS · BSD-3-Clause · 38.7k GitHub stars · quiet 180d+

    VerdictBSD-3-Clause HTTP CLI. Free forever; use when you want readable API calls, not curl flag gymnastics.

    CatchSOFT: Last significant push late 2024 — stable but not rapidly evolving. Vs curl (ubiquitous) and HTTPX (Python library): HTTPie is the *CLI UX layer*, not a scripting library and not installed everywhere by default. Python dependency means pip install or brew, not a static binary. curl still wins for one-liners in CI scripts expecting it.
