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
Per-object cap	not applicable
Retention	dies with the tab
Egress	the client's own connection
Identity	anonymous no signup on the sites that offer it
Limits	retention-clamped 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
Binding	retention-clamped
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. The census was right to refuse to count these.
Evidence rung	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
Checked	2026-10-23 (live); stale on 2026-11-22
