## AgentSphere

AgentSphere is an AI-native cloud infrastructure service whose purpose is to run untrusted, machine-generated code safely. Rather than letting an agent touch a production system directly, you hand it an isolated cloud sandbox where it can execute Python or TypeScript, read and write files, and stream results back in real time. The platform advertises sub-second cold starts, in-region deployment, and isolation backed by lightweight virtual machines such as Firecracker, with SOC2 and GDPR compliance positioned as built-in rather than bolted on.

What differentiates AgentSphere is its MCP-first design. Rather than requiring a custom SDK for every use case, it exposes cloud sandboxes to MCP-capable clients, so an assistant or agent framework can request execution as just another tool. It also supports stateful workflows: sandboxes can persist storage, snapshot their state and be reactivated by events, which matters for long-running or multi-stage agent tasks. Typical scenarios include agent-driven DevOps and GitOps automation, large-scale model evaluation and fine-tuning experiments, secure data analysis, and rendering AI-generated dashboards or visuals inside an isolated environment.

AgentSphere targets developers and platform teams building AI products as well as enterprises that need governance. It is model- and language-agnostic, so it does not lock you to a single LLM provider or runtime, and it offers private deployment in your own AWS, GCP or on-prem environment with network isolation. Because it is developer infrastructure rather than a consumer app, adoption usually starts with a free trial and scales into usage-based or enterprise plans; the vendor does not publish fixed public price points, so commercial terms are typically discussed directly.

**Pricing & Plans:** No fixed public tiers. AgentSphere offers a free trial and positions itself around flexible, usage-based and enterprise plans (bursting compute, private deployment, SLAs); pricing is available on request.

- **MCP-integrated cloud sandboxes:** Connect MCP-capable clients and agents directly to isolated cloud sandboxes to execute AI-generated code and handle files securely.
- **Fast, isolated execution:** Cold-start latency advertised as low as roughly 100ms, with sandboxes deployed in-region and isolation backed by lightweight VMs such as Firecracker.
- **Stateful agents and multi-stage tasks:** Support for long-running workflows with storage persistence, snapshot recovery, streaming output and event-triggered reactivation.
- **Security and compliance posture:** SOC2 and GDPR compliance, access control, output tracing and full audit logging designed for running untrusted AI code in regulated environments.
- **Private deployment options:** Deploy inside your own AWS, GCP or on-prem infrastructure with VPC peering, identity controls and network isolation.

**Strengths:** Purpose-built for agentic workloads rather than retrofitted from a generic VM or container service; MCP-first integration lowers the effort to wire execution into existing AI assistants and frameworks; Strong isolation and compliance story (Firecracker-based VMs, SOC2/GDPR claims) suits regulated industries; Model- and language-agnostic, with private deployment in your own cloud and support for stateful, long-running tasks

**Limitations:** No transparent public pricing, which makes budgeting harder before a sales conversation; Feature set and claims lean enterprise-heavy, so simpler hobby projects may find it more than they need; Complex setup compared with a local code interpreter for very lightweight experimentation

## Kosa8

Kosa8 targets the gap between agents that are useful and agents that are safe to leave unattended. Coding agents such as Claude Code and Codex normally inherit your shell, SSH keys and cloud credentials, so a single poisoned dependency or injected instruction can reach everything you own. Kosa8 instead gives each agent its own sealed virtual machine: a real VM with its own kernel and disk rather than a shared-kernel container. It sees one mounted folder — typically the repository — while API keys remain on your computer and only placeholder values appear inside.

The product is built around control of three things: files, credentials and network. The network is closed except for hosts the agent genuinely needs, routed through an egress broker whose rules are enforced on the host where nothing inside the sandbox can tamper with them. Bad runs are undone with a rewind instead of a rebuild, and a running sandbox can be forked into several live copies so parallel attempts are cheap. Governance features extend this to regulated teams: signed organisation policies, two-person approvals for risky actions, CUI labels that can only rise, FIPS 140-3 builds and signed evidence packages that an auditor reviews without trusting you.

Deployment is deliberately local-first. Kosa8 installs in one line on Apple-silicon Macs, x86-64 Linux, and Windows 11 through WSL2 in preview, and can also run in your own cloud or fully air-gapped. A Docker-compatible API means existing Docker CLI and Compose workflows keep working, and ready-made kits launch Claude Code, Codex, Gemini or your own agents. Security and incident-response teams use the same primitives for malware analysis and training ranges, where detonations produce signed reports and each trainee gets a live clone that resets in seconds.

**Pricing & Plans:** Every plan is free for 14 days with no card required, and each tier includes monthly Kosa8 Cloud credit for cloud sandboxes. Solo is $29/month (4 agents at once, 64 GB of sandboxes, $10 Cloud credit), Pro is $89/month (16 agents, 128 GB, $25 credit), Team is $169 per person per month from 3 people (48 shared agents, 256 GB, $40 credit per person) and Scale is $199 per person per month from 5 people (160 shared agents, 500 GB, $50 credit per person). Billing is cancel-any-time from the billing portal, and annual payment saves roughly 17%. Air-gapped and Enterprise terms are negotiated directly.

- **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.
- **Forking and Docker compatibility:** Clone a running sandbox into multiple live copies, keep the run that passes, and give each trainee or task its own reset-on-demand machine.
- **Tamper-evident audit and approvals:** Every action is hash-chained and marked human or agent, risky steps can require two named approvers, and exports are signed so a third party can verify them offline.

**Strengths:** 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

**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
