Poolside: A Windsurf Alternative for Enterprise AI Coding with On-Prem Deployment

Poolside is an enterprise AI platform developed by Poolside AI. It provides foundation models purpose-built for software engineering, combined with IDE extensions for VS Code, Visual Studio, Zed, and JetBrains, a terminal CLI (pool), and web-based access — all deployable within your own infrastructure. As a Windsurf alternative, it is best suited for enterprise engineering teams and defense or government organizations that require air-gapped, on-premises AI coding assistance with full model sovereignty.

Poolside vs. Windsurf: Quick Comparison

Key Strengths

• Full model sovereignty: Poolside delivers full model weights to your infrastructure. You are not API-dependent — the model runs entirely within your security boundary, with no external calls and no data egress.
• Broad IDE support: VS Code, Visual Studio, Zed, and JetBrains are all supported with native extensions, plus a terminal CLI (pool) and browser-based access. Teams using heterogeneous editor setups can use Poolside without switching IDEs.
• Enterprise governance: The Poolside Console provides centralized RBAC, sandboxed agent execution, full audit trails per session, SIEM integration, and MCP server governance — designed to satisfy CISO and compliance requirements out of the box.

Known Limitations

• Pricing not public: Poolside operates on enterprise contracts. There is no self-serve pricing page or individual developer plan available publicly.
• Not a self-contained IDE: Poolside integrates with your existing editors rather than replacing them with a standalone IDE like Windsurf.

Best For

Poolside is built for enterprises and defense or government organizations that need AI coding assistance deployed within their own infrastructure — not connected to external cloud services. It is best suited for engineering teams with strict data residency, air-gap, or compliance requirements where tools like Windsurf's cloud-based approach are not acceptable.

Tech Details

• Type: Enterprise AI platform (IDE extensions + CLI + web)
• IDEs: VS Code, Visual Studio, Zed, JetBrains
• Key features: Foundation models (Laguna XS.2 + M.1), CLI (pool), sandboxed agent execution, MCP support, audit trails, RBAC, SIEM integration
• Privacy / hosting: On-prem, VPC, air-gapped, or bring-your-own-hardware — fully sovereign deployment
• Models / context window: Poolside Laguna XS.2 and M.1; context window not publicly documented

When to Choose This Over Windsurf

• Your organization requires AI coding tools deployed within your own infrastructure with no external data egress.
• You need support for JetBrains, Visual Studio, or Zed alongside VS Code in a single governed platform.
• You operate in a regulated industry or defense context where cloud-based AI tools like Windsurf are not permitted.

When Windsurf May Be a Better Fit

• You want a standalone AI IDE with immediate public access and self-serve signup — Poolside requires an enterprise contract.
• You are an individual developer or small team without enterprise procurement — Poolside has no individual developer plan.
• You prefer a single unified IDE experience rather than extending your existing editors.

Conclusion

Poolside is the right choice for enterprise or government teams that need AI coding assistance deployed within their own secure boundary with full model sovereignty and multi-IDE support. For developers seeking a self-serve AI IDE with no enterprise procurement process, Windsurf or Cursor remain more accessible alternatives.
