## 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

## VS Code

VS Code has grown from a lightweight code editor into a full development surface that spans hand-written code and delegated agent work. The core promise is unchanged: rich language support, precise navigation, an integrated debugger and terminal, and a source control view that keeps you in flow. What is new is the AI layer on top. Agents understand your codebase, work through a plan with you, apply changes across files, and present results for review rather than silently rewriting your project. A dedicated Agents window coordinates several agents running in parallel so you can move a backlog forward while you work on something else.

Under the hood, VS Code is deliberately open about how you build with AI. You are not locked to one vendor: you can choose models from Anthropic, OpenAI, Google or Microsoft, use open-weight models, or bring your own API key from another provider. You also choose the agent harness, whether that is Copilot, Claude or Codex. Model Context Protocol servers and the MCP registry extend what agents can reach, while custom agents, skills, instructions and hooks let teams encode their own conventions. Permissions, approvals and agent sandboxing give you control over what an agent is allowed to run.

Because AI features such as inline suggestions, chat and agent sessions are delivered through a GitHub Copilot subscription, the practical cost depends on your plan and how heavily you use agents. The editor, extensions, remote development support, terminal, debugging and Git integration remain free. With thousands of Marketplace extensions, accessibility features like screen reader support and high contrast themes, and a long track record of open development on GitHub, VS Code suits solo developers, small teams and large enterprises alike.

**Pricing & Plans:** VS Code itself is free and open source on all supported platforms. The built-in AI features — inline suggestions, chat and agent sessions — are delivered through a GitHub Copilot subscription: a limited free tier for occasional use, plus paid individual and business plans for higher usage, premium models and team controls. Marketplace extensions are mostly free, though some add their own paid tiers.

- **Agent collaboration and orchestration:** Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
- **Model and harness choice:** Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
- **Deep language support:** JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
- **Full development workflow:** Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
- **Continuity across surfaces:** Start a task locally, answer an agent's question from GitHub Mobile, redirect it in the Copilot CLI and let teammates review the pull request on GitHub.com. Settings Sync keeps everything aligned.
- **Open, extensible and everywhere:** Run the editor on Windows, macOS or Linux, in the browser at vscode.dev, inside a container, over SSH or WSL, and reach agents on your machine through Dev Tunnels.

**Strengths:** Free, open-source editor with a mature extension ecosystem and years of active development; AI agents work directly on your real codebase with plans, diffs and reviewable changes; Freedom to mix models from Anthropic, OpenAI, Google, Microsoft or open-weight providers, and to pick the Copilot, Claude or Codex harness; One setup covers local development, containers, SSH, WSL, remote tunnels and browser-based editing

**Limitations:** AI agent and chat features require a paid GitHub Copilot plan, and heavier agent workflows consume premium request quotas quickly; The full agent feature set spans VS Code, the Copilot CLI, GitHub Mobile and GitHub.com, which can feel fragmented while the ecosystem matures; Extensions run with editor privileges, so a poorly maintained or malicious add-on can pose a supply-chain risk; Large workspaces with many extensions and language servers can get memory-hungry and slow on modest hardware
