19 Best AI Code Editors for Windows in 2026

OpenAI Codex is OpenAI’s coding agent, built on the o3 model family and designed for tasks that go beyond autocomplete. It runs as a cloud agent you give a task to, and it works through that task autonomously: reading your codebase, writing code, running tests, and iterating until the task is done or it needs your input. On Windows, it runs via the CLI (PowerShell or Command Prompt) or integrates as an agent inside ChatGPT.

The key difference from most tools here is the async workflow. You hand Codex a task, and it runs in a sandboxed environment in parallel. You can queue multiple tasks at once and come back to review results. It reads your repo, understands context across files, and cites which files it changed and why. Pricing is usage-based through your OpenAI account rather than a flat monthly subscription.

Cursor is the AI IDE most professional developers reach for first. It is built on VS Code, so your existing extensions, themes, and muscle memory carry over. The agent mode can plan and execute multi-file changes autonomously, and the Auto model-routing makes your monthly credit pool go further by picking the most cost-effective model automatically.

The Pro plan ($20/month) includes $20 of frontier model credits. When credits run out you can enable pay-as-you-go, or stick to Auto mode which is unlimited. The free Hobby tier gives 50 premium requests and 500 free-model requests per month : enough to evaluate the editor.

Windsurf is Cursor’s closest competitor and for multi-step autonomous tasks, many developers prefer it. The differentiator is Cascade, Windsurf’s in-house agent built specifically for software engineering. Cascade tracks context across an entire session, knows what it has changed, and course-corrects when something breaks.

Windsurf updated its pricing from a credit system to daily and weekly usage allowances: Free, Pro ($20/month), Teams ($40/user/month), Max ($200/month), and Enterprise. The Pro plan covers daily use for most developers under normal workloads. Windsurf also has its own SWE model family (SWE-1 model family) trained specifically for software engineering tasks.

GitHub Copilot is the most widely used AI coding tool in the world. The Stack Overflow 2025 Developer Survey placed it at 67.9% usage among developers using AI tools. It works inside VS Code, JetBrains IDEs, Visual Studio, Neovim, and on GitHub.com, so one subscription covers your entire workflow.

The free tier gives 2,000 inline completions and 50 agent or chat requests per month. Pro ($10/month) adds 300 premium model requests, code review, and a coding agent. Pro+ ($39/month) pushes to 1,500 premium requests and wider model access. The biggest advantage over Cursor or Windsurf is ecosystem depth: Copilot connects your editor, pull requests, and GitHub CLI under one account.

This is the most popular AI coding setup on Windows. VS Code is already the dominant editor on Windows, and adding Copilot as an extension gives you inline completions, an in-editor chat panel, and agent mode inside the workspace you already know. No learning curve, no migration, no new editor to configure.

This is listed separately from GitHub Copilot (above) because the experience differs meaningfully. When Copilot runs in VS Code, it has access to your open files, terminal output, and workspace context in real time. It is the same subscription, but the in-editor workflow is what most Windows developers actually use day to day. Install the Copilot extension from the VS Code marketplace, sign in with GitHub, and the free tier activates automatically.

Zed is not a VS Code fork. It was built from scratch in Rust for raw speed, and the difference is noticeable. Keystroke latency in Zed is lower than in VS Code or Cursor, especially on large files. For developers who find VS Code slow or heavy, Zed is worth trying for the editing experience alone.

The AI layer supports Zed-hosted models (billed per token), bring-your-own API keys across Anthropic, OpenAI, Google, and others, and fully local model runtimes via Ollama and LM Studio. You can use Zed with full AI features and never pay Zed a cent if you bring your own keys. Zed Pro ($5/month in token credits) is for developers who prefer Zed-hosted models. Students get $10/month free for one year.

Trae is built by ByteDance and is currently in preview. The entire editor, including access to Claude and GPT-4o, is free right now. No trial period, no credit cap, no credit card required. That will change when it exits preview, but right now it is the most generous free offering on this list for a full IDE experience.

The SOLO agent can orchestrate the editor, terminal, and browser together to complete tasks. The interface is cleaner than Cline and more beginner-friendly than Cursor. For developers who want to try an agentic IDE without committing to a subscription, Trae is the obvious starting point.

Cline is an open-source autonomous coding agent that runs inside VS Code. It can read and write files, run terminal commands, open a browser, and chain all of those actions together to complete a task. Every action requires your approval before it executes, so you stay in control even when Cline is working autonomously.

The extension is free. You connect your own API keys (Anthropic, OpenAI, OpenRouter, Bedrock, Gemini, and others) or point it at a local model via Ollama or LM Studio. Your actual cost depends on which model you use. Light users typically spend $5 to $20 a month in API costs. Heavy agentic users can spend significantly more.

If you already use a JetBrains IDE, the AI Assistant is the obvious first stop. It adds AI completions, chat, and an agentic coding layer called Junie that understands JetBrains-specific context: refactoring actions, project structure, and inspections. No other tool on this list has that level of IDE-native integration for Java, Kotlin, C#, or Python projects on JetBrains tooling.

The free tier includes local model completions via Ollama or LM Studio and a small cloud credit quota, with 30 days of AI Pro to start. AI Pro ($10/month) gives roughly $10 in cloud AI credits. AI Ultimate ($30/month) is for heavier use. Both tiers support BYOK, so you can bypass the cloud quota entirely by connecting your own API keys.

Amazon Q Developer (formerly AWS CodeWhisperer) is built for developers who work inside the AWS ecosystem. It does what every other tool does : completions, chat, and agent mode : but it also understands AWS services, IAM policies, CloudFormation templates, and infrastructure-as-code patterns at a depth that general-purpose tools do not match.

The agent mode can handle language migration tasks like upgrading a Java 8 codebase to Java 21+, tasks that would take days manually. IDE chat runs on the latest Claude model on Amazon Bedrock with a 200k token context window on both free and Pro tiers. The free tier gives 50 agentic requests per month. Pro ($19/month) increases limits and removes the free-tier data training policy.

Tabnine is aimed at enterprise teams with strict data requirements. It can run fully on-premises, inside a private VPC, or in an air-gapped environment where no code ever leaves your network. No other tool on this list offers the same range of deployment options for regulated industries.

The Dev Plan ($9/user/month) includes cloud-based completions and chat with models from Anthropic, OpenAI, Google, Meta, and Mistral. Enterprise ($39/user/month, annual) adds private deployment, IP indemnification, and admin controls. Tabnine discontinued its free tier in April 2025. If you need a proper free tier, other tools on this list serve that need better.

Gemini Code Assist has the most generous free tier on this entire list. Individual developers get 6,000 code-related requests and 240 chat requests per day at no cost, with a personal Gmail account and no credit card required. That is more than enough for full professional use.

The VS Code extension works like GitHub Copilot: inline completions as you type, a chat panel on the side, and agent mode for multi-file tasks. For developers already in the Google ecosystem (Firebase, GCP, Android), Gemini Code Assist has context awareness that other tools lack. Teams can upgrade to a paid plan ($19/user/month) for admin controls and higher limits.

Roo Code started as a fork of Cline and has grown into its own tool with one million users. The main difference from Cline is speed and a role-based execution system. You can switch between modes such as Architect (for planning), Code (for writing), and Test (for reviewing), each with its own system prompt and behavior tuned to that task.

The extension is free and open source. You pay only for API usage through whichever provider you connect: Anthropic, OpenAI, OpenRouter, Gemini, DeepSeek, and local models via Ollama. If Cline feels too strict or too slow for your workflow, Roo Code is the natural alternative to try first.

Continue is the most IDE-agnostic tool on this list. It runs as a VS Code extension and as a JetBrains plugin using the same configuration. That matters if your team uses both editors, or if you personally move between them. No other BYOK tool here covers both ecosystems equally well.

You connect any AI provider you have access to: Anthropic, OpenAI, Gemini, Ollama for local models, and a range of others. Continue adds tab autocomplete, a chat panel, and an edit mode that applies changes inline. It has over 26,000 GitHub stars and active enterprise adoption, which means the feature set is well-maintained and the enterprise configuration options (custom context providers, workspace-level setup) are real.

Aider is different from everything else on this list. It is a command-line coding agent that lives in your terminal and works directly with your git repository. You describe what you want to change in natural language, Aider edits your files, and creates a proper git commit. No GUI, no VS Code extension, just your terminal and your codebase.

The use case where Aider stands out is large-scale refactoring. When you need to rename something across 30 files, update an interface and all its implementations, or apply a structural change across a codebase, Aider handles it quickly and commits the result cleanly. On Windows, it runs in PowerShell or WSL. Install via pip and connect your API key.

Visual Studio (the full IDE, not VS Code) is Windows-only and is the primary tool for .NET, C#, C++, and enterprise Windows development. GitHub Copilot integrates directly into Visual Studio 2022 and later, giving you inline AI completions, a chat panel, and agent mode inside Microsoft’s most powerful Windows IDE.

This is the same Copilot subscription as entries 3 and 4. One $10/month Pro subscription covers VS Code, Visual Studio, JetBrains IDEs, and GitHub.com. If you are a Windows developer in .NET or C#, the Visual Studio integration deserves its own mention because Cursor and Windsurf do not have a Visual Studio equivalent. The free Copilot tier works here too.

Kiro is Amazon’s standalone agentic IDE, built as a VS Code fork and launched in July 2025. It takes a different approach from Cursor and Windsurf through what it calls spec-driven development. Instead of jumping straight into code, Kiro asks you to define requirements first. It generates a requirements document with user stories, a design spec, and a task list, then works through those tasks as an agent. The result is code that stays aligned with your original intent even across long sessions.

On top of specs, Kiro has “hooks”: automated triggers that run when specific events happen in your project, such as running tests automatically after every save or updating documentation when an API changes. It runs natively on Windows x64 and ARM64. The free tier gives 50 credits per month, with 500 bonus credits on signup. Pro starts at $20/month. All plans run on the latest Claude models via Amazon Bedrock. We have a full guide at the link below.

Google Antigravity is Google’s agentic IDE, launched in November 2025 as a VS Code fork for Windows (x64 and ARM64). Like Cursor, Windsurf, and Kiro, it is built on the VS Code open-source base with AI features baked in at the core. The editor has tab autocompletion, natural language code commands, and a context-aware agent. What sets it apart from the other VS Code forks is synchronized agentic control across your editor, terminal, and browser at the same time, so the agent can read and act across all three surfaces in one workflow.

The individual plan is free and includes access to the latest Gemini, Claude, and OpenAI models. No other IDE on this list gives you that model breadth on the free tier. Higher rate limits come through Google One (AI Pro or Ultra) and Google Workspace for teams. It also has an Agent Manager for running multiple agents across workspaces at once. We have a full setup guide on the site.
