| Free tier | a Linux userland running in the browser tab, free with no signup on some sites unit none; metered on none; WebVM is the strongest: real Debian x86 and real Tailscale networking, and it dies with the tab |
|---|
| Price | none stated |
|---|
| Limits | - retention-clamped (binding) closing the tab ends the environment; state survives only as an IndexedDB snapshot source
- request-rate the guest runs on the browser's own memory, so the machine's RAM is the ceiling source
the CPU is the reader's own, so this is not remote capacity at all |
|---|
| Identity | anonymous no signup on the sites that offer it |
|---|
| Egress | a user's own connection |
|---|
| Retention | dies with the tab |
|---|
| Interface | ssh a browser tab; no inbound endpoint |
|---|
| Tooling | a WASM Linux userland in the tab |
|---|
| Composes with | none: the machine is the reader's own laptop |

| Reliability | no reliability event recorded |
|---|
| Notes | Not remote compute: the cycles are the reader's own and the state dies with the tab. |

| Evidence note | documented the site was read on 2026-10-22 and states the free no-signup path, the IndexedDB snapshot on tab close, the opt-in WISP TCP egress and the guest-port tunnel. The record was already dead with a note that the environment ends when the tab closes, which the page confirms is a snapshot rather than a loss |
