Each term below has a stable HTML anchor. Cross-page first-use linking writes the term as `[term](/docs/glossary#term)` so a reader unfamiliar with the vocabulary lands here.

### Agent

A persistent isolated Linux VM running code-server in the browser. One Agent per account-slot, one Hetzner server (or Fly app for legacy) per Agent. See [Get started with Agents](/docs/agents/tutorial/get-started).

### Plain VM

A bare Linux server you SSH into directly. No Docker image, no managed IDE. One Hetzner server per Plain VM, customer-editable firewall. See [Get started with Plain VMs](/docs/plain-vms/tutorial/get-started).

### Glamp

An environment snapshot published from an Agent — tarball plus manifest — that anyone can adopt to spin up an Agent in the same state. Stored in S3, addressable at `crabglamp.com/{slug}/{name}`. See [Publish your first glamp](/docs/glamphub/tutorial/publish-your-first-glamp).

### Vault

Per-account store of customer-owned SSH public keys, attached to Plain VMs at provisioning time. v1 stores public keys only — no other secret types.

### Virtual key

Platform-issued LLM/voice credential prefixed `cg-pk-`. Authenticates against the central proxy; the proxy forwards to OpenAI, Anthropic, or ElevenLabs using CrabGlamp's pool credentials. One spend cap covers the key across all providers.

### Region

The data center hosting the resource. US (Hetzner Hillsboro, OR) or EU (Helsinki) at v1. Fixed for the resource's lifetime.

### Billing item

A billable line on your account's subscription — one Agent's compute, a virtual key's LLM spend, a virtual key's voice spend, or one Plain VM's compute. (LLM and voice are separate billing items that share one key and one spend cap.)

### Billing type

For Agents and Plain VMs, the choice of pay-as-you-go (metered) versus subscribe-and-save (flat-rate). For LLM/voice, always metered.

### Lifecycle event

An immutable audit record of an ownership transition — transfer or destroy — for an Agent or Plain VM. Persists even after the resource is destroyed, so usage history stays attributable. (Plain VMs record only destroy.)

### Tier

Size class for Agents and Plain VMs — small, medium, large. Determines vCPU, RAM, and disk. See [Limits and quotas](/docs/limits).

### Cell

The pair (tier, region). Each cell has its own per-second price.

### Cloudflare Tunnel

The data-plane edge for Agents on Hetzner. The Agent's host opens an outbound connection to Cloudflare; the public URL is served by Cloudflare's anycast network. Agents have zero inbound ports — Cloudflare handles TLS, routing, and DDoS.

### Manifest

The JSON descriptor of a glamp at `~/glamp.json` — name, displayName, description, tags, and the platform-assigned `glampId` after the first publish. Authored on the Agent, published with the tarball. There is no license or version field at v1.

### Glampignore

A `~/.glampignore` file in the Agent's home directory that excludes paths from the published tarball. Same format as `.gitignore`.
