Things to potentially add

• Tree-sitter playground

• @afnanenayet/diffsitter - Tree-sitter based diff tool

• @ul/kak-tree - Kakoune plugin for selections with tree-sitter

• @nvim-treesitter/playground - Tree-sitter playground implemented as a Neovim plugin

• @hercules-ci/canonix - Nix formatter based on Nix tree-sitter Parser

• @borkdude/analyze-reify - Clojure code analysis with tree-sitter

• @viktorstrate/swift-tree-sitter - Swift bindings

• @euclidianAce/ltreesitter - Lua bindings

• @tjdevries/tree-sitter-lua - Neovim plugin for improved tree-sitter support when editing Neovim lua files

Parsers

• @gagbo/tree-sitter-org - Emacs Org-mode parser

Other

• Adding more Atom plugins might be worthwhile, but I wouldn't say it's a very high priority.

I put these here because I don't know enough about the projects to really justify adding them (with the exception of the playground).

Some of them are also rather early in development (kak-tree says that it's currently a proof-of-concept).
