Asynchronous linting and fixing for Vim/Neovim with Language Server Protocol (LSP) support.
ALE is a Vim/Neovim plugin that performs asynchronous linting (syntax and semantic checking) and code fixing as you type. It integrates with a wide range of linters and language servers to provide real-time feedback without blocking the editor, helping developers catch errors early in the editing process.
Vim and Neovim users who want real-time syntax checking, code fixing, and LSP features (like go-to-definition and hover) directly within their editor, without relying on external IDEs.
ALE offers a lightweight, dependency-free solution with extensive language support, high customizability, and seamless asynchronous operation. It stands out for its stability, low resource usage, and ability to run in remote shells or constrained environments.

ALE has no external dependencies like JavaScript or Python, ensuring low memory footprint and easy installation, as highlighted in the key features.
Runs linters in the background using Vim/Neovim job control, so editing isn't blocked and errors appear before saving, per the asynchronous linting description.
Works with hundreds of linters and tools across many programming languages, providing wide coverage without extra plugins, as noted in the supported tools list.
Offers extensive options for linters, fixers, and UI elements, thoroughly documented in :help ale-options, allowing precise control over linting behavior.
Configuring linters for C/C++ projects often requires manual compiler flag setup or generating compile_commands.json files, as admitted in the FAQ, adding overhead.
ALE's LSP support is more limited compared to dedicated clients like coc.nvim, lacking some advanced IDE functionalities such as full refactoring or complex code actions.
Running multiple linters simultaneously can lead to high CPU usage and battery drain, though configurable with delays, as warned in the FAQ about battery power.
