r/neovim on Reddit: Which python language server/lsp is better?

July 29, 2023 -

Hey guys! I am new to neovim and I'm really loving it. Today I was setting up lsp and I am stuck.

What python lsp would be better? As far as I know there are jedi, pyright, python-lsp-server.

There is [[https://www.reddit.com/r/neovim/comments/rjrytp/which_python_lsp_is_better/ | this]] but its quite old.

I was using pyls but it is slow on big projects. Switched to pyright recently, I am happy so far, very fast, instant completion. Here is the related parts of my literate configuration: Python , lsp-mode&lsp-ui , lsp-pyright

go with mspyls or pyright. Have used all three and I think pyright > mspyls > pyls.

r/Python on Reddit: What are the best linters and language servers for python?

March 11, 2025 -

All of the different language servers, linters, and formatters available for Python can be very confusing. There is significant overlap between tools and it's hard to know what is what- this is my attempt to sort through it all.

Below is what I have been able to figure out, corrections and additions added as I see them from the comments.

Ruff is a fast linter / code formatter. It has overtaken Black and Flake8 as the best / most popular linter although not as thourough as Pylint. Rust.

JEDI is a static analysis tool that supports autocompletion, goto, and refactoring. It works with several langauge servers. Similar functionality to Pyright. Python.

Pyright is a language server maintained by Microsoft. It supports type checking (primary function), goto, autocomplete, similar to JEDI. It is written in TypeScript. Pylance is a Microsoft product that builds on Pyright and adds additional feataures to VS Code. TypeScript.

Basedpyright is a fork of Pyright to add Pylance functionality to Pyright for non-Microsoft editors. Mostly TypeScript with Python additions.

MyPy is one of the original static type checkers (2012, but still actively maintained). Python.

PyLSP/Python LSP Server is a language server implementation that interfaces with other libraries like JEDI to provide various LSP functionality. Python.

Pylint is a static code analyser and very thorough (and slow) linter. It can be used alongside other analysis tools like Ruff or Black, and mypy or pyright. Python.

In addition to the above, some commercial IDEs like PyCharm use their own proprietary linters and type checkers.

I use the Helix editor and by default it will use Ruff, JEDI, and pylsp together. I was confused why it used more than one language server/library, which was the motivation for looking into all of this.

ruff and pyright are the best

Also consider basedpyright, which is a fork of pyright where they try to achieve feature parity with pylance

Unfortunately there isn’t really a LSP feature compatibility list that gives you features point by point. All the LSP’s kinda handle different things in different ways and some like ruff are lsp’s but they are focused only on the formatting and linting parts of the coding process so no go to definit…

I use coc nvim woth coc pyright. The black and sort-imports for formatting

Still pyright, which is the only one that can show more details if you're using tensorflow and/or pytorch, at least from my experience. I also used pylsp for a (long) while before doing any ML. It is a decent one but, from my experience, the trade-off is: While it uses less-CPU than pyright, pyright can display the completion menu much noticeably faster.

I found two python lsp i.e. [pyright](https://github.com/microsoft/pyright) and [python-lsp-server](https://github.com/python-lsp/python-lsp-server), which is better in every aspect of coding or using them both would be better?

Pyright is written in NodeJS and its development seems less than open (see pull requests on the Github site). I have chosen PyLSP and it seems there is more fun around that (and I have contributed to the development of https://github.com/python-rope/pylsp-rope ).

I do not think it is possible to use multiple at the same time 🤔. There is also https://github.com/pappasam/jedi-language-server . Personally I do not want to use anything JS based but also my work revolves a lot around GObject based libraries like GStreamer. From what I understand Python GObject project does not provide the necessary stubs which can be used by Pyright to provide things like auto completion. Jedi lang server and python lsp server which are based on jedi, I think rely on runtime introspection to make those work. So I can only use these two. There are some differences between the two which you can see from readme. Like jedi language server does not support formatting but has document highlight while for python language server it is opposite. Pyright is faster from what I have read. The other two can be slow on large python files or the ones which load big libraries. My personal choice is jedi language server.
