How to read this 2026 comparison
Void and Windsurf are both strong options in AI IDEs, but they optimize for different workflows. This page combines structured specs with excerpts from our full reviews so you can decide without opening ten tabs.
Void at a glance
Void is an open-source, privacy-focused fork of VS Code. It allows you to use AI features with local models or your own API keys, ensuring your code never leaves your machine without permission.
Standout strengths: Privacy first; Local model support; VS Code compatible. Typical use: Privacy-sensitive projects. Pricing: Free.
Windsurf at a glance
Windsurf is the first agentic IDE, built by Codeium. It features "Flows" that allow the AI and developer to work in a continuous loop, sharing context and tools.
Standout strengths: Deep context awareness; Agentic "Flows"; Fast performance. Typical use: Complex refactoring. Pricing: Freemium.
Decision framework
| If you need… | Lean toward |
|---|---|
| Lowest friction daily coding | The tool that matches your IDE and VCS stack |
| Long-horizon refactors | Stronger multi-file / agent features |
| Cost control | Compare Free vs Freemium plus inference |
| Compliance | Confirm DPAs before enabling cloud agents |
Many teams pilot both for two weeks on the same ticket sample, then standardize on one primary tool and keep the other for specialized tasks (reviews, migrations, or docs).
Quick Summary
Void is a Free AI IDEs tool — the privacy-focused open-source ai editor.. It stands out for privacy first and local model support. Well suited for privacy-sensitive projects.
Windsurf is a Freemium AI IDEs tool — the first agentic ide by codeium.. It excels at deep context awareness and agentic "flows". Well suited for complex refactoring.
On pricing, Void (Free) and Windsurf (Freemium) take different approaches, which may be a deciding factor for budget-conscious teams.

Rating: 9.1/10 (Best for Privacy)
1. Executive Summary
Void is an open-source fork of VS Code designed for developers who want the power of AI without sending their code to a third-party cloud. It allows you to connect directly to models (LLaMA 3, DeepSeek) running locally or via your own API keys, ensuring zero data retention by intermediaries.
2. Core Features
- Privacy First: Your code never leaves your machine unless you explicitly send it to an API you control.
- VS Code Fork: Fully compatible with all VS Code extensions.
- Local Model Support: Native integration with Ollama for running models like DeepSeek Coder locally.
3. Pricing
- Free: Open source and free to use.
Windsurf
AI IDEs · FreemiumThe first agentic IDE by Codeium.
1. Introduction: The Agentic Challenger
If Cursor is the aggressive disruptor, Windsurf (formerly Codeium) is the thoughtful architect. Launched in late 2024 and hitting its stride in 2026, Windsurf markets itself not just as an AI editor, but as the first true "Agentic IDE."
Built by the team at Codeium (who built the popular extension used by millions), Windsurf takes a different approach to context. Instead of just indexing your files, it models your intent. With features like "Flows 2.0" and "Cascade", it aims to keep you in the "flow state" by proactively fetching the information you need before you even ask for it.
This review explores why many senior engineers are choosing Windsurf over Cursor in 2026.
2. What is Windsurf?
Windsurf is a standalone IDE, also based on VS Code (Code OSS). This ensures compatibility with the vast ecosystem of extensions.
However, Windsurf replaces the standard VS Code engine with the Windsurf Engine. This engine is "context-first." It constantly builds a knowledge graph of your repository, your recent edits, your terminal output, and even your documentation.
The "Cascade"
The heart of Windsurf is Cascade. It's not just a chat bot; it's an orchestrator.
- Deep Context: Cascade can see what you are looking at. If you highlight a function and say "Fix this," it knows "this" refers to the function, but it also checks the call sites of that function across the project to ensure the fix doesn't break anything else.
- Tool Use: Cascade can run
grep,ls, and even run your test suite to verify its own suggestions.
3. Key Features: The 2026 Deep Dive
3.1. Flows 2.0 (The "Loop")
In 2026, Windsurf introduced Flows 2.0. A "Flow" is a continuous session between you and the AI.
- Collaborative Editing: In most AI tools, it's turn-based. You ask, AI answers. In a Flow, you and the AI edit the file together. You might write the function signature, and the AI fills the body instantly. You delete a line, and the AI suggests a replacement in the sidebar.
- Auto-Continue: If a generation is cut off (due to token limits) or if a task requires multiple steps (edit file -> run test -> fix error), Flows 2.0 handles this loop automatically without you needing to prompt "Continue."
3.2. Supercomplete (Tab on Steroids)
Codeium's autocomplete has always been fast. In Windsurf, it's predictive.
- Next-Edit Prediction: It doesn't just complete the line; it predicts the next action. If you add a new field to a database schema, Supercomplete will jump your cursor to the API endpoint handler because it knows that's where you need to go next.
- FIM (Fill-In-the-Middle): It excels at inserting code into the middle of existing blocks without breaking syntax.
3.3. Windsurf Plugins (The "Everywhere" Strategy)
Unlike Cursor, which locks you into their IDE, Windsurf acknowledges that you might sometimes need to use Xcode, JetBrains, or Vim.
- Unified Context: The .codeium context folder is shared. If you switch to the Codeium plugin in IntelliJ for a backend task, it remembers the context from your Windsurf session in the frontend. This "roaming profile" is unique to the Codeium ecosystem.
3.4. Enterprise-Grade Security
Codeium (the parent company) is SOC 2 Type II compliant and offers self-hosted options.
- No Training: They explicitly guarantee that your code is never used to train their base models.
- Local Indexing: The vector index of your codebase is stored locally on your machine, not on their cloud.
