How relay data works
The short version
SHAI-hosted traffic uses your hosted allowance. Direct connections through a local or personal Connector use your own network instead. Your allowance counts both upload and download traffic and is shared across your workspaces.
Terminal traffic and files
When SSH traffic travels through SHAI’s hosted relay, terminal input and output, protocol traffic, and file transfers carried on that route count toward hosted usage. A direct local or personal Connector route bypasses that hosted relay path.
Automatic SSM cleanup
For AWS Session Manager connections, the selected Connector or hosted relay holds a short-lived signed request that can terminate that one session if your browser disconnects. This exposes that session’s ID and signed request metadata to the cleanup owner, but not your AWS secret key or terminal contents. The owner cannot use the request to start sessions or run commands. Cleanup closes the connection; work running in tmux can continue.
Personal relay fallback
A personal relay can connect directly or through SHAI’s hosted bridge. If it uses the hosted bridge as a fallback, traffic carried by that bridge counts toward hosted usage. Owning the remote Connector does not make a hosted fallback path unmetered.
Private application previews
Previews served through SHAI’s hosted preview service use hosted data. This also applies when the underlying SSH connection uses a local or personal Connector.
Limits and resets
See Billing for your account’s included allowance, current usage, reset date, and hosted per-file limit. Those hosted per-file limits do not describe a direct Connector’s network capacity.
Extra hosted data
Eligible paid plans can purchase additional hosted data when checkout is available. The current advertised packs are 25 GB for $4.49, 100 GB for $19.99, and 500 GB for $89.99 USD. Packs are used after included data and remain valid for 12 months. Billing shows current offers and availability before purchase.
