Managed Agent Zero Hosting

About Agent Zero

Agent Zero is a general-purpose AI agent framework with full access to its own Linux environment — it writes and executes code, installs packages, browses the web, manages files, and interacts with external APIs. It can delegate subtasks to subordinate agents, create its own tools, and maintains persistent memory across sessions. Supports multiple LLM providers including OpenAI, Anthropic, Google, and local models.

Questions people actually ask

What is managed Agent Zero hosting?

It means Agent Zero runs on infrastructure operated by a provider rather than on your laptop or a VPS you maintain. Mantlecore handles VM provisioning, the host, HTTPS, persistent storage, backups and the supported update path. You keep control of the model, credentials, tools, data and services the agent can reach.

Does each Agent Zero deployment get its own VM?

Yes. Every Agent Zero deployment gets its own virtual machine with its own guest kernel rather than a customer container sharing the host kernel with other customer workloads. That boundary does not replace scoped credentials, network policy or approval for high-impact actions.

Is this the same as running Agent Zero in Docker on a VPS?

No. A normal Docker container shares the VPS host kernel. Mantlecore gives each customer agent its own VM and guest kernel and manages the surrounding host, HTTPS, backup and supported update path. Docker or a self-managed VPS remains a good option when you want root control and are prepared to operate those layers yourself.

Will my Agent Zero files, projects and memory survive a restart?

Yes. The workspace uses persistent storage, so files, project data, settings and memory are not discarded during a normal restart. A daily off-site backup is a separate recovery control, retained for 7 days on Starter and 30 days on the larger plans.

Can I use my own model API key?

Yes. You can bring a supported provider key or use managed model access and pay from credit. In either case, prompts and relevant context are sent to the model provider you select. That model traffic leaves the VM by design.

Who controls the tools, credentials and services Agent Zero can reach?

You do. Mantlecore operates the hosting layer, but you decide which credentials to provide, which tools to enable and which external services the agent may access. Use scoped credentials and keep human approval for actions involving production systems, money, private data or irreversible changes.

What happens if an Agent Zero update fails?

You decide when to update. Mantlecore takes a snapshot immediately before the version change. If the post-update health check fails, the update rolls back automatically. You can also choose to roll back later within the available snapshot path.

Can a snapshot or backup reverse something Agent Zero already did elsewhere?

No. A restore recovers machine state captured at that point. It cannot reverse an action already completed in an external system. A sent message, payment, published change or external database write remains done.

How much does managed Agent Zero hosting cost?

Plans start at $19 per month and include a 7-day free trial and $2 of managed AI credit for new accounts. A payment card is required at signup, although the trial itself is not charged. The pricing page contains the current plan limits and terms.

Should I use Mantlecore, A0 Launcher or a self-managed VPS?

Use A0 Launcher or a self-managed VPS if you want direct host control and are comfortable managing firewalling, HTTPS, access, monitoring, updates, backups and restore testing. Use Mantlecore if you want a persistent Agent Zero VM with those infrastructure responsibilities handled for you.
