Open-source alternatives to Codacy

I want to pick an open-source replacement for Codacy. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - ESLint: ESLint is a free tool that automatically checks JavaScript code for bugs and style problems, pointing out patterns that may cause errors. It is aimed at programmers who write JavaScript and want their code checked as they work. [Advanced setup; devices not listed; replaces fully; MIT; https://github.com/eslint/eslint] - Ruff: Ruff is a free tool that checks Python code automatically for bugs and style problems, and can also fix some of them. It is aimed at programmers who write Python and want their code checked quickly. [Advanced setup; Windows · Mac · Linux; replaces fully; MIT; https://github.com/astral-sh/ruff] - Biome: Biome is a free tool that checks and tidies up code for websites and web apps, such as fixing layout and spotting mistakes. It is aimed at programmers who build web projects. [Advanced setup; Windows · Mac · Linux; replaces fully; Apache-2.0; https://github.com/biomejs/biome] - Semgrep Community Edition: Semgrep Community Edition is a free tool that scans computer code to find bugs and rule violations, by searching for patterns that look like the code itself. It is aimed at programmers, security auditors and consultants who run scans from the command line. [Advanced setup; Mac · Linux; replaces partly; LGPL-2.1; https://github.com/semgrep/semgrep] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/linters.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/linters.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
