What is Windsurf?
Windsurf is an AI-native code editor built as a fork of VS Code by Codeium, a company that has raised over $150 million in funding. Unlike traditional AI extensions, Windsurf embeds AI — primarily through its Cascade agent — directly into the IDE as a first-class feature. It ships its own proprietary AI models (SWE-1 and SWE-1.5) designed specifically for software engineering tasks, alongside support for Claude, GPT-4o, and Gemini.
Windsurf's design philosophy centres on flow: the AI maintains context across an entire session and operates autonomously, with fewer interruptions than most competing tools.
Is Windsurf free?
Yes. Windsurf has a free tier that includes unlimited Tab autocomplete and 25 prompt credits per month. The 25 credits translate to roughly 3–5 meaningful Cascade agent sessions — enough to evaluate the tool but not for daily professional use.
Windsurf pricing (April 2026, post-March quota update):
| Plan | Price | Includes |
|---|---|---|
| Free | $0/month | Unlimited Tab autocomplete, 25 credits/month |
| Pro | $15/month | 500 credits/month, all premium models |
| Max | $40/month | Higher credit allocation, priority access |
| Teams | $30/user/month | 500 credits/user, admin controls (SSO +$10/user) |
| Enterprise | Custom (~$60/user) | 1,000 credits/user, SOC 2, HIPAA, FedRAMP |
How does Windsurf compare to Cursor?
Both are VS Code forks with AI built into the core — the most direct comparison in the market. The key differences:
- Price: Windsurf Pro is $15/month vs Cursor Pro's $20/month
- Agent autonomy: Windsurf's Cascade acts more aggressively by default — it executes without waiting for confirmation at each step. Cursor's Composer pauses more often for review.
- Pricing model: Windsurf uses a credit/quota system (variable cost depending on model and usage intensity); Cursor uses flat-rate subscription (predictable cost)
- Background agents: Cursor has cloud VM-based background agents triggerable via Slack/GitHub; Windsurf does not currently offer this
- Tab autocomplete: Both offer unlimited Tab completions; Cursor's are considered slightly more polished for large TypeScript codebases
For VS Code developers who want comparable capability at a lower price and prefer the AI to take more initiative, Windsurf wins. For developers who want maximum control and predictable billing, Cursor is the stronger choice.

How does Windsurf compare to GitHub Copilot?
The most important difference is architecture: Windsurf is a standalone IDE, GitHub Copilot is an extension that works inside your existing editor — VS Code, JetBrains, Neovim, Visual Studio, Xcode, and more.
If you work in JetBrains or any editor other than VS Code, Windsurf is not available to you. GitHub Copilot is.
If you are already in VS Code: Windsurf's Cascade agent is ahead of Copilot Edits for autonomous multi-file tasks. Copilot wins on pricing ($10/month Individual vs $15/month Pro) and enterprise admin controls (SSO is included in Copilot Business at $19/user; Windsurf Teams requires an extra $10/user for SSO).

What is Windsurf Cascade?
Cascade is Windsurf's autonomous coding agent — the feature that most distinguishes it from tools like GitHub Copilot. When you give Cascade a task, it plans the work across your codebase, reads all relevant files, writes and edits code across multiple files, runs terminal commands, and handles errors — all without waiting for approval at each step.
This level of autonomy is Windsurf's primary competitive advantage. Cascade is the most hands-off agent mode among major AI coding IDEs, which makes it fast for complex tasks but requires more trust in the AI's judgment.
Cascade uses credits from your monthly quota. Windsurf's proprietary SWE-1 and SWE-1.5 models consume a fixed credit cost per Cascade interaction; third-party models like Claude Sonnet 4.6 charge credits proportional to the tokens consumed.
How does Windsurf's credit system work?
This changed significantly in March 2026. Windsurf replaced its old monthly credit pool with a quota system that has daily and weekly reset caps.
The old model let you spend all 500 credits in a single day if needed. The new quota model distributes your monthly allocation across daily and weekly limits — you cannot front-load usage onto high-intensity sprint days.
Credit consumption by model:
- SWE-1 / SWE-1.5 (Windsurf's own models): Fixed cost per Cascade interaction, regardless of session length. Most predictable and cost-efficient.
- Claude Sonnet 4.6 / GPT-4o: Charged proportional to token volume. Long multi-file sessions with large codebase context can consume 20–40 credits in a single interaction.
A developer running 10–15 Claude-powered Cascade sessions daily will exhaust 500 Pro credits in under two weeks. Developers primarily using SWE models will have a much lower consumption rate.

Does Windsurf work in JetBrains or Neovim?
No. Windsurf is only available as a standalone IDE — a VS Code fork. It does not have plugins for JetBrains (IntelliJ, PyCharm, WebStorm, GoLand), Neovim, Vim, Visual Studio, or Xcode.
If your primary development environment is not VS Code, Windsurf is not currently an option. GitHub Copilot has the broadest IDE support across major editors. Continue.dev also supports JetBrains.
Is Windsurf Tab autocomplete unlimited?
Yes. Tab completions in Windsurf — its inline code suggestions that appear as you type — never count against your credit quota on any plan, including free. This is one of Windsurf's clearest pricing advantages over some competitors.
Only Cascade agent sessions, chat interactions with premium models, and Command mode consume credits.
What AI models does Windsurf support?
Windsurf supports a mix of its own proprietary models and third-party frontier models:
Windsurf proprietary:
- SWE-1 — Windsurf's first software engineering model
- SWE-1.5 — faster version, optimized for agent tasks
Third-party (consume credits proportional to tokens):
- Claude Sonnet 4.6 (Anthropic)
- Claude Opus 4.6 (Anthropic)
- GPT-4o and GPT-5 (OpenAI)
- Gemini 3.1 Pro (Google)
You can switch models within Cascade sessions. Using Windsurf's own SWE models is more cost-efficient; using Claude or GPT-4o gives you more flexibility at higher credit cost.
Does Windsurf send my code to the cloud?
Yes — like all cloud-based AI coding tools, Windsurf sends code context to its servers to generate Cascade responses and Tab completions. Windsurf's paid plans do not use your code for model training.
At the enterprise level, Windsurf offers SOC 2 Type 2, HIPAA, and FedRAMP High compliance — making it one of the few AI coding tools cleared for government and healthcare environments.
If you need code to remain entirely on-premises, Windsurf Enterprise offers VPC deployment options. For a fully local setup without enterprise pricing, Cline with Ollama or Continue.dev with local models are the strongest alternatives.
Can I import my VS Code extensions into Windsurf?
Yes. Because Windsurf is a VS Code fork, it supports VS Code extensions natively and imports your existing extensions, themes, and settings during setup. The transition from VS Code is typically seamless and takes under 30 minutes.
A small number of extensions with proprietary VS Code marketplace dependencies may behave differently, but the vast majority work without modification.
Is Windsurf better than Cursor?
For VS Code developers who want the most autonomous AI agent at a lower price, Windsurf is a strong choice. Cascade's hands-off approach is genuinely ahead of Cursor's Composer for developers who prefer to delegate and review results rather than approve each step.
For developers who rely heavily on fast tab completions, Cursor's predictive completions have a slight edge for large TypeScript codebases. For developers who want background agents that run asynchronously via Slack or GitHub, Cursor is currently the only option.
Neither is objectively better — the right choice depends on your working style. Windsurf suits developers who think in sessions ("complete this feature"); Cursor suits developers who think in precise requests.
What are Windsurf Rules and how do I use them?
Windsurf Rules are project-level configuration files that shape how Cascade AI behaves in your specific project. You can define coding conventions, file structure rules, testing standards, and workflow preferences that apply to every Cascade interaction automatically.

How much does Windsurf actually cost per month?
It depends on which models you use and how intensively:
- Using SWE-1/SWE-1.5 models exclusively: Pro at $15/month is the total cost. Credits are consumed at a fixed, predictable rate.
- Moderate use with Claude Sonnet 4.6: Pro at $15/month covers typical usage (2–4 Cascade sessions per day). Heavy use may require add-on credits.
- Heavy use with Claude/GPT-4o daily: Pro may run short mid-month. Budget for Max ($40/month) or add-on credits.
GitHub Copilot at $10/month is cheaper with fully predictable costs — no credit monitoring required. Windsurf's price advantage over Cursor ($15 vs $20) is real but narrower once you factor in the variable cost of premium model usage.
What are the best alternatives to Windsurf?
- Cursor — slightly more polished IDE experience with background agents, $20/month flat
- GitHub Copilot — works in JetBrains and all major editors, $10/month, fully predictable pricing
- Cline — free open-source agent in VS Code, pay only for API tokens, deep MCP integration
- Continue.dev — open-source, fully configurable, supports local models
