Is hotcell right for you?

A good fit for

Relevant to developers isolating agent workloads while examining which secrets enter each runtime.

Before you choose

Docker, Linux/KVM Firecracker and macOS Apple VZ paths differ. Linux/microVM egress can be kernel-enforced; macOS Docker enforcement is advisory. Import explicitly chooses gateway, inject or skip: injected secrets do enter sandboxes. Non-HTTP protocols, request signing, mTLS and OAuth refresh exchanges are not transparently protected; hardcoded SDK hosts may bypass routing without enforced egress. Resource capacity and isolation depend on runtime/hardware. Benchmarks and security claims were not independently reproduced. No software, sandbox, secret import, command or network route was executed.

Workflow and handoff

Create only a disposable sandbox with fake credentials, verify deny behavior and token revocation, and inspect all inject choices before real secrets.

The practical questions

Frequently asked questions

Was the application hands-on tested?

No. This listing is based on dated official-source evidence and a visual artwork check. Unconfirmed costs and restrictions are identified explicitly.

What is hotcell used for?

hotcell provisions agent sandboxes on owned hardware through containers or supported microVM runtimes. A host gateway can replace provider credentials with scoped sandbox tokens, while fleet monitoring, admission control and optional egress policies manage execution.

Does hotcell have a free plan?

Apache-2.0 software is free; hardware, hosting and model/provider charges remain separate.. This record lists ongoing free access; check the plan limits before starting.

How much does hotcell cost?

No paid monthly price is listed; this record treats the product as free to start. See the plan cards for entitlements, billing commitments and seat minimums.

Can I use hotcell through an API?

CLI, self-hosted sandbox SDK and Python SDK are described, with configurable HTTP provider routes and metered/spend-capped gateway tokens.. API access and subscription access may have different terms; consult the linked sources.

What should I check before choosing it?

Docker, Linux/KVM Firecracker and macOS Apple VZ paths differ. Linux/microVM egress can be kernel-enforced; macOS Docker enforcement is advisory. Import explicitly chooses gateway, inject or skip: injected secrets do enter sandboxes. Non-HTTP protocols, request signing, mTLS and OAuth refresh exchanges are not transparently protected; hardcoded SDK hosts may bypass routing without enforced egress. Resource capacity and isolation depend on runtime/hardware. Benchmarks and security claims were not independently reproduced. No software, sandbox, secret import, command or network route was executed.
