Augment Code vs Windsurf: Which AI Scales With Your Codebase?
August 28, 2025
Augment Code scales better for enterprise-grade codebases because its Context Engine processes 400,000+ files with architectural awareness, while Windsurf's local indexing caps at 10,000 files and lacks enterprise compliance certifications.
TL;DR
Enterprise codebases with hundreds of thousands of files cause most AI coding assistants to produce architecturally inconsistent suggestions due to limited indexing capabilities. Augment Code's Context Engine processes 400,000+ files across multiple repositories with ISO/IEC 42001 certification, while Windsurf's VS Code fork optimizes for rapid prototyping with a 10,000-file local indexing limit.

What to Consider When Deciding Between Augment Code and Windsurf
- Context Scale: Whether your AI assistant can handle massive enterprise codebases (Augment Code's Context Engine processes 400,000+ files with architectural understanding; Windsurf's local indexing caps at 10,000 files)
- IDE Integration Approach: Native plugins for your existing development environment (Augment Code: VS Code, JetBrains, CLI, Vim; Windsurf: VS Code fork using Open VSX Registry)
- Workflow Automation Depth: Autonomous agent workflows spanning multiple repositories versus visual prompt chaining for quick tasks
- Enterprise Governance: SOC 2 Type II compliance and ISO 42001 certification (Augment Code verified) versus zero data retention mode (Windsurf)
- Extension Ecosystem: Full marketplace compatibility (Augment Code) versus Open VSX registry limitations (Windsurf)
Augment Code achieves 70.6% SWE-bench score versus GitHub Copilot's 54% through its Context Engine's architectural-level understanding across 400,000+ files.
How Augment Code Compares to Windsurf
Augment Code embeds directly into VS Code, JetBrains, and Vim with autonomous agents that understand entire repository architectures. Windsurf operates as a VS Code fork built around Cascade's agentic capabilities, which make up to 20 tool calls per prompt.
Augment's Context Engine enables semantic understanding across 400,000+ files, maintaining real-time awareness of cross-repository dependencies. This enables autonomous workflows like the Agentic Tasklist system that plan, execute, and self-correct multi-file refactors without breaking existing functionality.
Windsurf's Cascade Agent operates with a 20 tool calls per prompt limit, balancing comprehensive code understanding against response latency. The visual flow interface lets developers chain prompts interactively, preview changes inline, and iterate rapidly on smaller codebases.
Feature Breakdown: Augment Code vs Windsurf
| Category | Augment Code | Windsurf |
|---|---|---|
| Context Engine | Processes 400,000+ files | 10,000 files local maximum |
| IDE Integration | Native VS Code, JetBrains, Vim, CLI | VS Code fork with Open VSX |
| Enterprise Compliance | ISO/IEC 42001, SOC 2 Type II | Zero data retention mode |
| Autonomous Workflows | Agentic Tasklist, cross-repo automation | Cascade agent (20 tool calls/prompt) |
| Extension Compatibility | Full VS Code Marketplace | Open VSX registry only |
Category-by-Category Comparison
1. Workflow Automation Capabilities
| Feature | Augment Code | Windsurf |
|---|---|---|
| Autonomous Task Planning | Agentic Tasklist with editable planning | Cascade with Code and Chat modes |
| Multi-File Coordination | Context Engine across 400,000+ files | RAG-based retrieval for open files |
| Long-Running Sessions | Agent tool calls with memory management | 20 tool calls per prompt limit |
When Augment Code's agents receive complex requests, they execute complete workflows: breaking tasks into steps, running tests, opening pull requests, and self-correcting failures. The Tasklist system enables "gradual trust building" where teams review plans before execution, then monitor autonomous implementation across multiple repositories.
Windsurf's Cascade Agent excels at interactive development with its 20 tool calls per prompt flowing through Search, Analyze, Web Search, Model Context Protocol, and terminal access. This works well for rapid prototyping where immediate feedback matters more than autonomous execution. Context management between sessions depends on leveraging features like context pinning and Cascade Memories to maintain continuity.

2. Context Processing and Scale
| Feature | Augment Code | Windsurf |
|---|---|---|
| Context Engine | Processes 400,000+ files | 10,000 files local maximum |
| Real-Time Updates | Continuous indexing | Manual re-indexing required |
| Multi-Repository | Native support | Remote indexing via servers |
Enterprise development happens in continuously evolving codebases. Augment Code's Context Engine maintains semantic maps of how microservices, configuration files, and shared libraries interconnect. When teammates merge changes to authentication libraries, the context updates in approximately 100ms, keeping AI suggestions architecturally consistent without manual intervention.
Windsurf's local indexing caps at 10,000 files due to RAM limitations. For perspective, a typical React application with node_modules can easily hit 50,000+ files, exceeding this limit. Remote indexing is available through Windsurf servers for larger repositories but requires manual triggers through a web interface and operates on intervals rather than real-time updates, potentially breaking flow state during active development.
3. Enterprise Security and Governance
| Feature | Augment Code | Windsurf |
|---|---|---|
| Security Certifications | ISO/IEC 42001, SOC 2 Type II | Not published |
| Data Processing | Customer-managed encryption keys | 4 subprocessors with code access |
| Governance Features | Augment Rules, audit trails | Zero data retention mode |
Augment Code achieved ISO/IEC 42001 certification, the AI-specific governance standard covering training data handling, model behavior monitoring, and algorithmic decision management. Combined with SOC 2 Type II compliance and customer-managed encryption keys, this addresses governance requirements that traditional security frameworks miss. The Augment Rules system enables organization-wide policy enforcement through configuration files in your repository.
Windsurf offers zero data retention mode for team and enterprise plans, ensuring code snippets are not retained. Standard operations involve multiple subprocessors with code access: Google Cloud Platform, Oracle Cloud, Anthropic, and OpenAI. For regulated industries requiring complete data sovereignty without relying on zero data retention mode, this architecture creates compliance considerations that enterprise governance frameworks must address.
