Browser agents and stealth cloud browsers for real web tasks
–Per-task and per-hour costs can add up quickly at high volume
–Stealth browsing raises ethical and terms-of-service questions teams must handle
–Cloud usage requires an API key and some engineering integration

Secure, sovereign sandboxes for enterprise AI agents
Sealed VM per agent
Every agent runs in a genuine VM with its own kernel and disk on Apple's Virtualization framework or KVM, not in a container that shares the host kernel.
Credential protection by placeholder
The sandbox sees one mounted folder and holds placeholder values instead of real API keys, which stay on your host and are brokered only to approved hosts.
Host-enforced network egress control
The network is closed by default; traffic flows only to allow-listed hosts through a broker whose rules live on the host, out of reach of anything inside the sandbox.
One-second snapshots and rewind
Checkpoint before risky work and restore a running machine, processes included, in about a second rather than rebuilding it from scratch.
Strengths & Pros
+True VM-level isolation with a per-agent kernel instead of shared-kernel containers
+API keys never enter the sandbox, and network egress is closed by default and allow-listed
+Fast snapshots, restores and forks make parallel agent runs and disposable ranges practical
+Docker CLI and Compose work unchanged, so existing tooling and images carry over
+Governance-grade evidence: hash-chained audit trail, signed exports, two-person approvals, air-gapped and FIPS 140-3 options
+Runs on hardware you already own, including local models through an OpenAI- and Anthropic-compatible API
Limitations
–No permanently free tier — after the 14-day trial you must pick a paid plan starting at $29/month
–Host-folder mounts read at roughly a third of native disk speed, so heavy builds should stay inside the sandbox
–Full isolation is best on Apple-silicon Macs and x86-64 Linux; Intel Macs, Windows 10/ARM and JioOS need a paired host
–Team and Scale tiers are priced per person with seat minimums, which raises the entry cost for small groups
–Air-gapped and FIPS 140-3 deployments are still enterprise sales conversations rather than self-serve
