Reviewers mostly praise Zed for one thing above all: speed. They describe it as fast to launch, responsive on older machines, light on memory, and free of the bloat they associate with VS Code and other Electron-based editors. Many also like its clean, simple UI, built-in collaboration, and solid AI features, though some see the AI as good rather than best-in-class. The main caveats are a smaller extension ecosystem, lighter support for heavy workflows, and mixed language-tooling quality, with one maker of reporting slow Python LSP performance and incomplete Vim bindings.
