Northflank Sandboxes, secure microVM/sandbox product for running untrusted / AI-generated code at scale (~200ms microVM spin-up), positioned for code-gen agents. Confirmed live June 2026 via northflank.com. Proprietary SaaS (Northflank Ltd).

Adoption

3 medium confidence

Northflank (platform-wide, primary): 2,000+ organizations, 80,000+ developers in production, 130B+ requests, millions of containers, 330+ availability zones. These are platform-level figures (not Sandboxes-specific); the Sandboxes product is newer. Placed at 3 on the developer/org base; the Sandboxes feature alone is likely lower.

Capability

4 medium confidence
4.0

Strong: microVM isolation, ~200ms cold-start, broad runtime support, multi-cloud scale, and explicit support for untrusted code-gen at scale. Just below frontier on proven sandbox-specific scale vs the dedicated leaders; isolation+latency are top-tier. Independent ComputeSDK TTI benchmarks confirm the top-tier latency, measuring ~100ms median cold-start (3rd-fastest of 19 sandbox providers), beating the ~200ms spec.
