How Windsurf Compares to JetBrains AI

Windsurf and JetBrains AI represent fundamentally different philosophies for AI-assisted development. Windsurf built a conversation-first IDE from scratch, prioritizing autonomous agents and minimal interface friction. The Cascade system reads project context, builds memories of previous commands, then executes multi-file changes, test runs, and deployments without requesting permission for each action.

JetBrains AI takes the opposite approach by integrating into the established IDE ecosystem developers already know. The AI assistant leverages IntelliJ's existing project-wide index for context-aware suggestions while preserving familiar keyboard shortcuts, tool windows, and inspection workflows. With model selection capabilities introduced in 2024, teams can choose between JetBrains' proprietary Mellum LLM, Google Gemini, OpenAI GPT-4, Anthropic Claude, or local models for air-gapped environments.

When using Augment Code's Context Engine, teams get the best of both approaches: autonomous agent capabilities with deep IDE integration across VS Code, JetBrains, and Vim/Neovim. The 70.6% SWE-bench score demonstrates superior performance on real-world software engineering tasks compared to conversation-only or suggestion-only approaches.

Category-by-Category Comparison

1. Test Automation & Scaffolding

FeatureWindsurfJetBrains AI
Automated Test Generation✅ Cascade agent executes tests with stack trace analysis✅ Right-click "Generate Unit Tests" with context menu generation

Working Code Examples

JetBrains AI Test Generation with TestSpark

typescript
// Original method in UserService.ts (v2.4.1+)
export class UserService {
async createUser(email: string, password: string): Promise<User> {
if (!this.validateEmail(email)) {
throw new ValidationError('Invalid email format');
}
return await this.repository.save({ email, password });
}
}
// Right-click → "Generate Unit Tests" produces:
// UserServiceTest.ts
import { UserService } from '../UserService';
import { ValidationError } from '../errors';
describe('UserService', () => {
let service: UserService;
beforeEach(() => {
service = new UserService(mockRepository);
});
test('should create user with valid email', async () => {
const result = await service.createUser('user@example.com', 'password');
expect(result.email).toBe('user@example.com');
});
test('should throw ValidationError for invalid email', async () => {
await expect(service.createUser('invalid', 'password'))
.rejects.toThrow(ValidationError);
});
});
// Common failure: Generated mocks may need manual import adjustment
// Fix: Ensure mockRepository is properly imported from test setup

Windsurf Cascade Agent Command

typescript
// Terminal integration with Cmd/Ctrl+I
// Natural language command:
"Run tests for UserService and fix any failures"
// Cascade executes automatically:
// 1. npm test src/services/UserService.test.ts
// 2. Analyzes stack trace if failures occur
// 3. Modifies test files based on error analysis
// 4. Re-runs tests until passing
// 5. Commits changes with descriptive message
// Cascade Hook Configuration (.windsurf/hooks/test.sh)
#!/bin/bash
export NODE_ENV=test
export DATABASE_URL=sqlite::memory:
npm run test:coverage -- --reporter=json
// Common failure: Hooks may not inherit environment variables
// Fix: Explicitly set all required env vars in hook scripts

Enterprise SSO Configuration

typescript
// Windsurf Enterprise SSO Setup (config.json)
{
"sso": {
"provider": "okta",
"domain": "company.okta.com",
"clientId": "${WINDSURF_SSO_CLIENT_ID}",
"scopes": ["openid", "profile", "email", "groups"]
},
"scim": {
"endpoint": "https://api.windsurf.com/scim/v2",
"bearerToken": "${SCIM_BEARER_TOKEN}",
"userMapping": {
"username": "userName",
"email": "emails[0].value"
}
}
}
// JetBrains AI Enterprise (IDE settings)
// Settings → AI Assistant → Enterprise Configuration
{
"aiProvider": "jetbrains-cloud",
"dataRetention": "zero",
"modelSelection": "mellum",
"onPremises": true,
"encryptionKeys": "customer-managed"
}
// Common failure: SCIM provisioning may timeout on large user sets
// Fix: Implement batch processing with 50-user chunks and retry logic
