## exe.dev

exe.dev is a Bay Area-built cloud computing platform aimed at a specific modern problem: developers increasingly run coding agents that need their own machines, and those machines need to behave like real servers rather than ephemeral containers. The product lets you buy a pool of vCPU and memory and then spin up as many VMs as you want inside it, fork them quickly, and SSH straight in with root access on Ubuntu-compatible images with apt and systemd available.

The platform positions itself as production-ready infrastructure, not just a scratchpad. VMs get fast, persistent, replicated NVMe storage, can be exposed publicly over HTTPS on *.exe.xyz subdomains, and can also host consumer-facing apps with authentication and secret management handled by the platform. A built-in LLM gateway can attach provider keys (OpenAI, Anthropic, xAI, Fireworks, Deepgram and others) to your machines so agents have model access without extra plumbing.

Pricing is transparent and published: a Personal plan starts at $15 per month for a 2 vCPU / 4 GiB pool, larger Personal pools scale up to 16 vCPU / 32 GiB, a Work plan adds SSO, unlimited users, larger VM counts per pool and hourly or monthly scaling, and Enterprise covers dedicated hardware and VPC connectivity. A seven-day trial is offered, and you can get started free through ChatGPT.

**Pricing & Plans:** Personal plans start at $15/month for 2 vCPU and 4 GiB of pooled memory, scaling to $155/month for 16 vCPU and 32 GiB. The Work plan is $75/month regular (intro $37.50/month for the first three months) with SSO, unlimited users and extra pool resources billed hourly. Enterprise pricing is custom, and a 7-day free trial is available.

- **Real persistent VMs, not sandboxes:** SSH into Ubuntu-compatible machines with root access, apt and systemd, then keep them running as long-lived servers instead of short-lived containers.
- **Pooled CPU and memory:** Buy vCPU and RAM once, then create as many VMs as you need inside the pool and fork them quickly for parallel agent work.
- **HTTPS and public hosting built in:** Expose internal apps privately or publish them publicly on *.exe.xyz subdomains, with auth and secret management handled for you.
- **LLM gateway for agents:** Attach OpenAI, Anthropic, xAI, Fireworks or Deepgram keys so agents running on your VMs have model access configured automatically.
- **Global regions and durable storage:** Deploy VMs across regions with fast, persistent and replicated NVMe storage, plus team features like SSO on higher-tier plans.

**Strengths:** Real root-access Linux VMs with persistent storage rather than ephemeral sandboxes; Transparent published pricing with a free trial and hourly scaling option; Built-in HTTPS exposure, auth, secrets and an LLM gateway for agent workloads; Fast VM creation and forking, useful for parallel agent tasks and preview environments

**Limitations:** Priced per resource pool, so heavy multi-VM usage can add up quickly; No free tier beyond the trial and ChatGPT-based signup path; Enterprise features such as VPC and dedicated hardware require contacting sales

## 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
