computer alternatives
Curated alternatives to computer — and why you'd switch.
mirage
Unified virtual filesystem for AI agents — mounts S3, Slack, Gmail, Postgres and ~50 backends as one tree so any bash-speaking LLM can grep and pipe across services. Snapshotable, embeddable.
Why switchBoth hand agents a virtual filesystem: mirage federates ~50 external backends into one read tree; computer owns authoritative state and adds execution surfaces on top.

CNCF-landscape sandbox platform for AI agents: multi-language SDKs, unified API, CLI and MCP over Docker/Kubernetes runtimes — coding agents, GUI agents, evals and RL training.
Why switchSandboxed execution for agents: OpenSandbox provisions Docker/K8s runtimes behind a unified API; computer gets the same job done with Durable Objects and Workers isolates.
Full comparison →CubeSandbox
Hardware-isolated microVM sandboxes for AI agents — sub-60ms boot, <5MB overhead, E2B-compatible API, self-hosted on your own KVM nodes.
Why switchSame job, opposite trust models: cubesandbox is hardware-isolated microVMs on your own metal; computer is Cloudflare-native isolates around a durable filesystem.
