Looking for the AI code completion tools worth trying this year? This guide covers 6 tools listed on TrendingDevTools, with what each one does, who it suits and its pricing or free tier, checked on each vendor's own site in October 2026.
Every tool here is listed on TrendingDevTools. We read each vendor's own website and pricing page for the plan details below. Where a vendor does not publish a number, we say so instead of guessing. Prices can change, so check the vendor's site before you buy.
GitHub Copilot is GitHub's AI pair programmer that works inside VS Code, JetBrains IDEs, Visual Studio, Xcode and more, plus on GitHub itself.
Cursor is an AI-first code editor built on the VS Code experience, with agent mode, chat and Tab autocomplete across your whole project.
Supermaven is a fast AI code completion tool that adapts to your coding style.
Zed is a fast, open-source code editor written in Rust with built-in AI agent features and multiplayer collaboration.
Junie is the AI coding agent from JetBrains that works in JetBrains IDEs and the terminal.
Cline is an open-source (Apache-2.0) coding agent for VS Code with Plan and Act modes and support for many model providers.
It suggests the next lines of code as you type, based on your file and project. You accept a suggestion with a key like Tab.
Supermaven describes itself as the fastest copilot, and Zed is built in Rust for speed. Try both in your own project to compare.
Yes. Supermaven has a free tier, and GitHub Copilot and Cursor both have free plans.
No. Completion suggests code as you type. Agents take a whole task, edit many files and run commands.
