2026-11-11에 검증된 OpenAITools.app 텔레메트리에 따르면, Kosa8(kosa8.com)은(는) AI Agent에 색인된 AI 플랫폼으로 월 0회 방문을 기록 중이며, 전월 대비 트래픽 변화량은 +0(0%)입니다. 주요 지리적 시장은 글로벌(트래픽 점유율 —)이며, subscription 가격 모델로 운영됩니다. 월간 트래픽 기준 주요 경쟁 대안으로는 Coder (월 14.94만회 방문), Agent 37 (월 18만회 방문), boat (월 6.69만회 방문) 등이 있습니다.

Kosa8 is an AI agent sandbox that runs coding and task agents inside sealed, dedicated virtual machines on your own hardware, your cloud, or a fully air-gapped network. Each agent gets its own kernel and disk and sees only one mounted folder, so API keys stay outside the sandbox as placeholders and the network stays closed except for hosts you allow through an egress broker. Teams install it with one line, run ready-made kits for Claude Code, Codex and Gemini, fork a running machine into parallel copies, rewind a bad run in about a second, and export hash-chained evidence a third party can verify.

## 개요

Kosa8 is an AI agent sandbox that runs coding and task agents inside sealed, dedicated virtual machines on your own hardware, your cloud, or a fully air-gapped network. Each agent gets its own kernel and disk and sees only one mounted folder, so API keys stay outside the sandbox as placeholders and the network stays closed except for hosts you allow through an egress broker. Teams install it with one line, run ready-made kits for Claude Code, Codex and Gemini, fork a running machine into parallel copies, rewind a bad run in about a second, and export hash-chained evidence a third party can verify.

## 가격 및 요금제

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.

## 주요 기능 및 역량

- **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.

## 주요 활용 사례

- **Unattended coding agents (Software engineering teams):** Run Claude Code, Codex or Gemini overnight against a real repository while the VM sees one folder, holds no real API keys, and can be rewound in about a second if a run goes wrong.
- **Malware analysis and cyber ranges (Security operations and SOC analysts):** Fork one prepared environment into per-trainee live clones and detonate malware samples in a sandbox whose only internet is simulated and recorded, producing a signed report for each run.
- **Audit-ready agent governance (Regulated finance, health and government teams):** Answer auditor questions with a hash-chained record of what the agent did, who approved it and where data went, backed by signed org policies, two-person approvals and offline licences.
- **Isolated execution per end-user task (AI product engineers):** Spawn a real VM per user task in a fraction of a second, fork running machines to explore alternatives, and keep only the copy that passes validation.
- **Local agents on a personal machine (Solo developers and small studios):** Install in one line on the Mac you already own, run local models behind an OpenAI- and Anthropic-compatible API, and let agents work the night shift without risking host credentials.

## 강점

- 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

## 한계

- 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

## 자주 묻는 질문

### Do I need an account or credit card to try Kosa8?
No. One command installs Kosa8 and every feature is unlocked for 14 days without an account or a card. You only sign up when you decide to keep using it.

### What happens after the 14-day trial ends?
Kosa8 is paid software with no permanently free tier. Plans start at $29 per month for Solo, and paying yearly saves roughly 17 percent.

### Does my code or data leave my machine?
No. Code, files and prompts stay wherever the sandbox runs — your laptop, your cloud or an air-gapped network. Licensing checks and usage counts come from an audit log you can verify yourself, and an offline licence sends nothing at all.

### Will sandboxing slow my agents down?
A container starts in about 178 ms and a running sandbox restores in under a second on real hardware. The one honest exception is a folder shared out from your host machine, which reads at roughly a third of native speed.

### Which computers does Kosa8 run on?
Apple-silicon Macs and x86-64 Linux run sandboxes natively, and Windows 11 on x86-64 works through WSL2 in preview. Other machines pair with a supported host in one command.

### Do we have to change how our team works?
No. The Docker CLI and Docker Compose keep working unchanged through a Docker-compatible API, and kosa8 agent run <kit> launches Claude Code, Codex, Gemini and other agents in one command.

### Can a regulated company use Kosa8?
That is a core audience. Kosa8 offers FIPS 140-3 builds, signed organisation policies, two-person approvals, CUI labels, air-gapped operation and signed evidence packages, with contract and procurement paperwork available on request.
