Windsurf

Agentic AI IDE with Cascade that writes, edits and runs code autonomously inside your editor

Windsurf is an agentic AI IDE built by Codeium, acquired by Cognition in 2026 and now rebranded as Devin Desktop. The free tier includes 25 prompt credits/month with unlimited Tab autocomplete; Pro is $15/month with 500 credits and access to premium models including SWE-1.5. Best for developers who want deep agentic automation — multi-step task execution, not just inline suggestions — inside a full IDE.

What is Windsurf?

Windsurf is an AI-native code editor built by Codeium around an agentic engine called Cascade. Where most AI coding tools offer autocomplete or single-turn chat, Cascade operates in multi-step flows: it reads context from across the codebase, writes changes to multiple files, runs shell commands, observes the output, and iterates — all without the developer manually directing each step. The editor is built on VS Code, so extension compatibility and keybindings carry over from existing setups.

Two features differentiate Windsurf from comparable editors. Codemaps generate structural dependency graphs of a project that the agent uses for project-wide reasoning, reducing the hallucination of non-existent functions or wrong import paths. Fast Context is a semantic indexing layer that lets Cascade locate relevant code quickly in large repositories where naive retrieval degrades. In 2026, following Cognition’s acquisition of Codeium, Windsurf gained an Agent Command Center — a Kanban-style interface for managing parallel agent sessions — and Spaces, which use Git worktrees to bundle context for multi-agent coordination. The product is in active rebrand to Devin Desktop; windsurf.com redirects to devin.ai as of June 2026.

Windsurf’s credit model prices proprietary SWE-1 and SWE-1-mini model usage at zero credits, while frontier models (Claude, GPT-4o, Gemini) draw from the monthly quota at rates derived from provider API costs plus a 20% margin.

Who is it for?

Windsurf suits developers who want automation that goes beyond inline suggestions — specifically, those who need the AI to carry out a defined task (refactor this module, add these tests, fix this bug end-to-end) rather than co-pilot line by line. The free tier’s unlimited Tab completions make it accessible for evaluation without commitment, though the 25-credit monthly cap limits agentic session depth.

Target users:

  • Solo developers on complex codebases who spend time navigating rather than writing — Cascade and Codemaps reduce the cognitive load of project-wide changes.
  • Startup engineers needing to move fast across the stack: the IDE, in-browser previews, and App Deploy pipeline sit in one tool without context switching.
  • Teams adopting multi-agent workflows — the Agent Command Center and Spaces features are designed for orchestrating several parallel Cascade sessions against a shared codebase.
  • JetBrains users who want AI assistance without migrating to a new editor — the plugin ecosystem covers IntelliJ, PyCharm, and WebStorm.

What people use Windsurf for

  1. 01 Autonomous multi-step refactors across a large codebase without manual file-hopping
  2. 02 Generating and running tests end-to-end inside the IDE without switching tools
  3. 03 Bootstrapping a new project from a plain-English description using Cascade Flow
  4. 04 Debugging sessions where the agent reads error output and applies fixes iteratively

Pros and cons

Pros and cons of Windsurf
Pros Cons
Cascade handles genuinely multi-step tasks — not just autocomplete but plan-and-execute flows Free tier's 25 prompt credits/month runs out quickly on agentic multi-turn sessions
Free tier includes unlimited Tab completions, uncommon among agentic IDEs windsurf.com now redirects to devin.ai — product identity mid-rebrand may confuse new users
Proprietary SWE-1.5 and SWE-1-mini models consume zero credits, extending free quota macOS-first; Windows and Linux support present but historically secondary
Codemaps give the agent structural project understanding that pure retrieval lacks Credit costs for frontier models (Claude, GPT-4o) can deplete Pro quota faster than expected

Frequently asked questions

Is Windsurf free?

Yes. The free tier is permanently available at $0 and includes 25 prompt credits per month plus unlimited Tab autocomplete. Credits reset monthly; proprietary SWE-1-mini model sessions do not consume credits.

How much does Windsurf Pro cost?

Windsurf Pro costs $15/month per seat. It includes 500 prompt credits per month, access to premium models including SWE-1.5, Fast Context, Codemaps, and full App Deploy capability. Extra credits are available at $10 per 250.

What happened to Windsurf — is it now Devin?

Cognition (the company behind Devin) acquired Codeium, the maker of Windsurf, in early 2026. The windsurf.com domain now redirects to devin.ai, and Windsurf IDE is being rebranded as Devin Desktop. Existing plans and settings are preserved for current subscribers.

What is Cascade in Windsurf?

Cascade is Windsurf's agentic engine. Unlike standard autocomplete, Cascade can plan a multi-step task, read relevant files, write changes across the codebase, run terminal commands, and iterate based on output — all in a single directed session.

How does Windsurf compare to Cursor?

Both are AI-native IDEs built on VS Code. Windsurf Pro is $15/month vs Cursor Pro at $20/month. Windsurf emphasizes deep agentic flows via Cascade and multi-agent coordination via Spaces; Cursor is known for its Composer feature and broad model selection. Feature parity is high; choice often comes down to workflow preference.

Does Windsurf work with JetBrains IDEs?

Yes. Windsurf provides plugins for 40+ IDEs including IntelliJ IDEA, PyCharm, and WebStorm, so developers on JetBrains toolchains can use Tab completions and some Cascade features without switching editors.

What models does Windsurf support?

Windsurf supports its own SWE-1, SWE-1.5, and SWE-1-mini models (zero-credit cost), plus Claude (Anthropic), GPT-4o (OpenAI), and Gemini (Google). Frontier model usage draws from your monthly credit quota at API-derived rates.
