Introduction

blink.cmp is a completion plugin with support for LSPs, cmdline, signature help and snippets. It uses an optional custom fuzzy matcher for typo resistance. It provides extensibility via pluggable sources (LSP, buffer, snippets, etc), component based rendering and scripting for the configuration.

Features

Works out of the box with no additional configuration
Updates on every keystroke (0.5-4ms async, single core)
Typo resistant fuzzy with frecency and proximity bonus
Extensive LSP support (tracker)
Snippet support: native vim.snippet (including friendly-snippets), LuaSnip and mini.snippets
External sources support (community sources and compatibility layer for nvim-cmp sources)
Auto-bracket support based on semantic tokens
Signature help (experimental, opt-in)
Command line completion
Terminal completion (0.11+ only! No source for shell completions exists yet, contributions welcome!)

Compared to built-in completion

Typo resistant fuzzy matching
- Smarter scoring
- Proximity + frecency score bonuses
Prefetching to minimize LSP latency
Support for external non-LSP sources (snippets, path, buffer, git, ripgrep, ...)
Ghost text
Automatic signature help
Auto-bracket support based on semantic tokens

Compared to nvim-cmp

Avoids the complexity of nvim-cmp's configuration by providing sensible defaults
Updates on every keystroke with 0.5-4ms of overhead, versus nvim-cmp's default debounce of 60ms with 2-50ms hitches from processing
- You may try magazine.nvim which includes many performance patches, some of which have been merged into nvim-cmp
Boosts completion item score via frecency and proximity bonus. nvim-cmp boosts score via proximity bonus and optionally by recency
Typo-resistant fuzzy matching unlike nvim-cmp's fzf-style fuzzy matching
Core sources (buffer, snippets, path, lsp) are built-in versus nvim-cmp's exclusively external sources
Built-in auto bracket and signature help support
Prefetching to minimize LSP latency
