FAQ

What's the best Windsurf alternative for enterprise teams?

Augment Code and Sourcegraph Cody lead for enterprise deployments. Augment Code provides the deepest codebase understanding through its Context Engine (400K+ files across repositories) with SOC2 Type II and ISO/IEC 42001 certifications. Cody offers proven enterprise adoption with quantified results: 1Password saves 7 hours per developer monthly, and Palo Alto Networks achieved 40% productivity gains across 2,000 developers. Choice depends on whether teams prioritize context depth (Augment) or code graph search capabilities (Cody).

Can AI code editors work in air-gapped environments?

Tabby and Augment Code provide full functionality in air-gapped environments. Tabby offers self-hosted LLM servers with Docker deployment running entirely within VPCs. Augment Code maintains complete Context Engine capabilities in on-premise deployments with air-gapped data center support. Void provides zero-telemetry local assistance where every model runs locally. Cody Enterprise offers limited air-gapped functionality but with reduced capabilities compared to cloud deployment.

How do AI editor context windows affect code quality?

Context window size directly impacts suggestion relevance for complex codebases. Limited context (8K-32K tokens) forces editors to miss cross-file dependencies, generating suggestions that break downstream services. Augment Code's 200K-token Context Engine processes entire service architectures simultaneously, reducing hallucinations by maintaining awareness of dependency graphs, error handlers, and API contracts across repositories. Zed offers 200K context through Claude 3.5 Sonnet integration for similar benefits.

What certifications should enterprise AI coding tools have?

Enterprise deployments should verify SOC 2 Type II (operational security controls), ISO/IEC 42001 (AI system management, currently only held by Augment Code among AI coding assistants), and relevant industry certifications (HIPAA for healthcare, PCI DSS for payments). Additional requirements include Customer-Managed Encryption Keys (CMEK), SSO/SAML integration, comprehensive audit logging, and RBAC with repository-level permissions. Self-hosted options inherit organizational certifications directly.

How much do Windsurf alternatives cost for teams?

Pricing varies significantly by deployment model. Zed offers free personal use with $10/month Pro tier. Continue provides free open source with $10/dev/month team plans. Tabby charges $19/user/month for Team tier. Augment Code ranges from $20/month (Indie) to $200/month (Max) with custom Enterprise pricing. Cody Enterprise costs $49/user/month following July 2025 discontinuation of lower tiers. Self-hosted options (Tabby, Aider, Void) eliminate per-seat costs but require infrastructure investment.

What to Do Next

The Windsurf migration concerns large, complex codebases needing tools built for enterprise complexity rather than demonstration projects. Every alternative takes clear positions on problems that matter: speed prioritization (Zed), security focus (Tabby, Void), terminal workflows (Aider), or comprehensive context understanding (Augment Code, Cody).

Autocomplete quality represents baseline expectations now. The real question becomes whether tools shorten gaps between ideas and production code without drowning workflows in context switches. When production-ready AI agents enable autonomous feature delivery while maintaining comprehensive codebase understanding through context engines that process entire codebases simultaneously, teams ship features without architectural archaeology or compliance compromises.

Start by identifying current pain points: cross-repository complexity, review cycle bottlenecks, or security compliance requirements. Pilot test with real features using small squads, measure for one sprint, then expand or rollback based on concrete metrics rather than polished demonstrations.
