Augment Code vs Windsurf

Augment Code and Windsurf target different layers of AI-assisted development. Augment Code's Cosmos platform is an enterprise-grade agent orchestration system that spans the entire SDLC. It features a suite of pre-built agents: Triage Work Dispatcher, PR Author, Deep Code Review, Tester, Pair Review, PR Risk Analysis, and Security Remediation. Its Context Engine uses structural code mapping to reduce token usage by up to 50%, and it offers human-in-the-loop smart escalation. Crucially, Augment Code is SOC 2 Type II, HIPAA, and ISO 42001 compliant, making it suitable for regulated industries. The latest news (2026-06-09) adds Claude Fable 5 for deep reasoning at ~2x cost of Opus 4.8, and the Cosmos platform launch (2026-06-03) unifies agents across the SDLC.

Windsurf (now Devin Desktop) is an IDE-centric agent command center. It allows dispatching and monitoring local (Devin Local) and cloud (Devin Cloud) agents from a single surface. Key features include Supercomplete, Fast Context for millisecond file lookups, agent diffs, and the Agent Client Protocol (ACP) for multi-model use. Windsurf offers free unlimited access to SWE-1.6, its own coding model. The latest news (2026-06-18) adds security review in Devin Review, catching auth bypasses and logic flaws. Notably, Claude Fable 5 was removed from Windsurf on 2026-06-09 following an Anthropic directive and US government announcement. Windsurf also has a plugin system (v3.2.16) and MCP subagent tool access.

Both tools have agents for similar tasks (code review, security), but Augment Code focuses on governed, standardized workflows for teams, while Windsurf emphasizes flexible agent orchestration in an IDE. Augment Code's agents are more specialized (PR Author, Tester, etc.), while Windsurf's agents are more generalist (local/cloud coding agents) with security review added.

Augment Code uses a contact-based pricing model tailored for enterprise customers. It is credit-based, and costs can escalate depending on usage of agents like Claude Fable 5, which runs at ~2x the cost of Opus 4.8. There is no public per-seat or monthly price, and it is not suitable for small budgets.

Windsurf operates on a freemium model. It offers free unlimited access to its SWE-1.6 coding model, making it accessible to individual developers without upfront cost. Paid tiers likely exist for Devin Cloud agent execution and additional features, but the baseline IDE with local agents is free. This makes Windsurf significantly more affordable and easier to try for individuals or small teams. For enterprises, the total cost of ownership for Windsurf versus Augment Code would depend on usage volume; Augment Code's credit system could become expensive at scale, but it includes compliance and governance that Windsurf lacks.
