StereOS or Spider Cloud: which should you choose?
| Dimension | StereOS | Spider Cloud |
|---|---|---|
| Pricing | Free | From $6/mo |
| Best for | Security teams that need kernel-level isolation for AI coding agents, not container namespaces, Self-hosted enterprise deployments running on bare metal | Engineering teams where pages-per-second throughput, not clicks, is the bottleneck, RAG and agent teams that want rendered pages back as markdown or structured JSON |
| Standout features | Run AI coding agents inside disposable sandboxed Linux VMs · Full VM isolation — each agent gets its own kernel, RAM, disk, and network · masterblaster (mb) CLI for install, sandbox lifecycle, and inspection | Scrape a single page into markdown, JSON, HTML, raw or plain text · Crawl whole sites with each page streamed as one JSONL line in order · Search across multiple search engines with automatic fallbacks |
| Viability score | 66/100 | 85/100 |
| API | No | Yes |

What users praise
- • Full-VM isolation gives each agent its own kernel, RAM, disk, and network
- • Buys secure boot, FIPS, and GPU passthrough that container and microVM stacks lack
- • Workflow is a tight CLI loop: mb pull, mb up, mb ssh, mb down, mb destroy
- • jcard.toml makes the agent, mixtape, and prompt declarative and reproducible
What frustrates them
- • Very little independent review data outside GitHub issues
- • Heavier resource footprint per agent than containers or microVMs
- • Top-level docs miss details that live only in subproject READMEs
- • Terminal-only workflow with no GUI, web console, or visual management
