microsandbox vs Vercel

Microsandbox runs untrusted workloads inside microVMs, each with its own Linux kernel, filesystem, and network boundary rather than sharing the host kernel. It can run AI agents, user code, plugins, CI jobs, scrapers, and automation. The local runtime starts on a user's machine without a daemon, root service, or account; it can also run on personal servers or clusters, and its cloud platform can be deployed in the user's infrastructure. Microsandbox offers SDKs for TypeScript, Rust, Python, Go, and Ruby, plus a CLI and MCP workflows, and accepts OCI images from container registries. By default, sandboxes can reach the public internet, while private, host-local, link-local, and metadata destinations are blocked; egress can be allowlisted or disabled. The runtime is open source under Apache 2.0. The Free plan is $0 per month, while paid plans start at $49 per month. Microsandbox Cloud is in private beta and requires an access request.

Vercel provides infrastructure for building, deploying, securing, observing, and scaling apps and agents. Connect a GitHub, GitLab, or Bitbucket repository to trigger automatic deployment when changes reach the connected branch. The platform includes automatic CI/CD, a global CDN, Fluid Compute, and traffic and performance insights. Listed frameworks include Next.js, Nuxt, SvelteKit, Nitro, Turborepo, TanStack Start, and FastAPI. Its marketplace includes integrations across AI, analytics, authentication, CMS, databases, commerce, and security; featured integrations include Neon, Shopify, and Resend. Vercel also lists AI SDK, AI Gateway, Sandbox, and Vercel Agent. Its Firewall provides automatic DDoS mitigation on all plans and custom rules to log, block, challenge, or rate-limit traffic. Hobby is free for personal, non-commercial use, with monthly limits and no option to buy usage beyond its caps. Pro costs $20 a month for one developer seat, includes a $20 usage credit, and charges pay-as-you-go beyond that credit. Enterprise pricing is custom.
