Claude Code vs Windsurf

Side-by-side comparison — features, pricing, pros and cons

Paid

4.2

Anthropic's terminal-based autonomous coding agent powered by Claude Opus 4.6 with 1M token context. Runs 30-hour autonomous tasks with access to your filesystem, shell, and test runners. Native IDE extensions for VS Code and JetBrains allow inline use alongside Cursor-style editing. Scores 74.4%–80.9% on SWE-bench Verified.

Category:AI Coding

Features

Powered by Claude Opus 4.6 with 1M token context window
Autonomous 30-hour task execution with filesystem, shell, and test access
SWE-bench Verified score: 74.4%–80.9% (leading among terminal agents)
VS Code and JetBrains IDE extensions for inline use
CLAUDE.md project configuration for persistent behavior rules
+5 more

Pros

Highest SWE-bench score among deployed terminal agents at 80.9% on the Verified benchmark
1M context allows loading an entire monorepo without chunking or losing cross-file coherence
Plan mode shows the full task breakdown before any code runs — essential for high-stakes refactors
Headless mode enables fully automated CI pipelines that can fix failing tests without human intervention

Cons

Cost scales with context usage — heavy 1M context tasks can cost $50–200 per autonomous session via API
Terminal-only workflow requires comfort with CLI; no GUI for reviewing diffs before execution in default mode
IDE extensions are newer than Cursor and lack some Cursor-specific features like Notepads
Rate limits on subscriptions constrain long autonomous sessions; API pricing is the practical path for heavy use
Security vulnerabilities found in versions prior to v1.0.20 — ensure you're running the current version

Windsurf

Freemium

4.0

AI code editor by Codeium built around the Cascade agent architecture, where the AI maintains a persistent understanding of your entire coding session rather than responding to isolated prompts. Cascade can plan and execute multi-step tasks while the developer continues working, with "flows" that track intent across file edits, terminal commands, and test results. Priced at $15–30/mo as a direct Cursor competitor.

Category:AI Coding

Features

Cascade agent with persistent session context across files, terminal, and tests
Flows: continuous AI task tracking that persists through developer interruptions
Windsurf Tab: context-aware multi-line code completion with cross-file awareness
Inline editing with natural language instructions on selected code
Built-in terminal with AI command suggestions and error explanations
+3 more

Pros

Cascade's session persistence means you can pause a multi-hour task and resume without losing AI context
Freemium tier is more generous than Cursor — 5 Cascade flows per day at no cost
Codeium autocomplete is lightweight and fast, consuming fewer resources than Copilot on low-RAM machines
Flows architecture is better suited to iterative feature development than one-shot Composer-style prompts

Cons

Smaller user base than Cursor (estimated 200K vs 1M+) means fewer community resources and extensions
Cascade can lose track of intent in flows longer than ~2 hours, requiring a manual context reset
No JetBrains support as of Q1 2026 — VS Code-based only
Pro plan ($15/mo) limits Cascade flows to 30/month; $30/mo for 90 flows
Codeium's model quality trails Claude and GPT-4o on complex reasoning tasks in the AI chat
