Supermaven
Fastest AI code completion with a million-token context window.
Supermaven is an AI code completion tool engineered for speed and deep codebase awareness, featuring a 1-million-token context window that allows it to consider far more of a project's code when generating suggestions than most competing tools. It delivers inline code completions with exceptionally low latency, making it one of the fastest options in the AI code assistance category.
The primary differentiator for Supermaven is the combination of speed and context. While most code completion tools work with context windows of a few thousand to tens of thousands of tokens, Supermaven's million-token window means it can hold a substantial portion of a codebase in context simultaneously. This translates into completions that are more consistent with project-specific patterns, naming conventions, and architectural decisions. The tool processes code locally where possible to keep latency minimal, and developers typically report that suggestions appear fast enough to feel like a natural extension of typing. Supermaven integrates with VS Code, JetBrains IDEs, and Neovim, covering the most widely used development environments. It offers multi-line completions and learns from the codebase it is working within, improving relevance over time.
Supermaven is best suited for individual developers and small teams who prioritize fast, accurate code completion without the overhead of chat interfaces or agentic features. Developers working on large codebases with extensive internal libraries and custom patterns benefit the most from the large context window, as Supermaven can reference those patterns more effectively than tools limited to smaller windows. It is a good fit for developers who want AI assistance during the flow of writing code without the interruption of switching to a chat panel or agent workflow.
Supermaven offers a free tier that provides useful daily code completion without requiring payment, making it easy to evaluate. The Pro plan unlocks additional capabilities and higher usage limits. The tool focuses exclusively on code completion and does not include chat, code generation from prompts, or autonomous agent functionality. For developers seeking a dedicated, fast, and context-rich completion tool rather than a full AI coding platform, Supermaven occupies a distinct and compelling niche in the market.

I like Supermaven a lot. It integrates well with my existing setup and the AI assistance is genuinely helpful. Just wish the larger context window was a bit better.

Decent tool that I'd recommend to colleagues. Supermaven particularly shines for writing boilerplate. Some features feel a bit rough around the edges but overall positive.
