CubeSandbox vs Stickerbox: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of CubeSandbox and Stickerbox — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
C
CubeSandbox
TencentCloud
Open-source, hardware-isolated sandbox service for AI agents — sub-60ms cold start, <5MB overhead, E2B-SDK compatible.
Key features
- Sub-60ms Cold Start: Average <60ms boot time and <5MB memory overhead per instance, so a single node can run thousands of agents.
- Hardware-Level Isolation: Each sandbox gets its own Guest OS kernel on RustVMM/KVM — no Docker shared-kernel escape surface for LLM-generated code.
- E2B SDK Compatibility: Drop-in replacement for the E2B SDK — swap one URL env var and existing agent code runs unchanged.
- AutoPause / AutoResume: Idle sandboxes automatically suspend and wake on the next request for aggressive cost optimization.
- Snapshot, Clone & Rollback: CubeCoW copy-on-write engine takes 100ms-granularity checkpoints so agents can fork, roll back, or replay any saved state.
- Credential Vault: Agents call LLMs and external APIs through a proxy — keys never enter the sandbox, model context or logs.
- Egress Control: Per-sandbox domain allowlists with instant block on unauthorized egress and full audit logs for compliance.
- Web Console & Templates: In-browser dashboard at :12088 for managing sandboxes, nodes, version matrix and OCI-image-based templates.
Best for
- Running Untrusted LLM Code: Execute Python/shell that a model wrote without risking the host through hardware isolation.
- E2B Migration: Move existing E2B-based agent workloads to on-prem/self-hosted infrastructure with zero code changes.
- High-Density Agent Fleets: Host thousands of concurrent agent sandboxes on a single node thanks to sub-60ms boot and 5MB overhead.
- Agent Snapshotting: Save state before a risky tool call and roll back on failure using CubeCoW snapshots.
- Compliance-Sensitive Agents: Enforce egress domain allowlists and audit logs for regulated environments.
- Self-Hosted Agent Infra: Deploy a multi-node cluster with the built-in Terraform module for private-cloud AI agent workloads.
