Free tier	No storage and no relayed bandwidth: Trystero borrows an existing decentralised network purely to exchange WebRTC SDP offers. unit mixed; metered on stored-bytes
Price	none stated
Per-object cap	not stated
Retention	not stated
Egress	Data flows peer-to-peer via WebRTC; the signalling network never sees the payload. The operator's cost is SDP messages only.
Identity	anonymous anonymous
Binding	none no constraint in the record binds at this scale; the record carries no limit of a kind the vocabulary names
Interface	unknown JavaScript library, `joinRoom` API
Tooling	npm @trystero-p2p/*
Composes with	The cleanest signalling example: because only SDP crosses the third party, there is no bandwidth quota to hit and no operator who could impose one. Note the caveat that WebRTC needs a TURN relay when both peers are behind symmetric NAT — that is where real relaying cost reappears, and Trystero does not supply it.
Reliability	No TURN service included; symmetric-NAT pairs will fail to connect rather than fall back.
Notes	No storage and no relayed bandwidth: Trystero borrows an existing decentralised network purely to exchange WebRTC SDP offers.

date	source	what it proved
2026-10-21	github.com/dmotz/trystero	'To establish a direct peer-to-peer connection with WebRTC, a signalling channel is needed to exchange peer information (SDP). Typically this involves running your own matchmaking server but Trystero abstracts this away'; strategies listed: BitTorrent, Nostr, MQTT, Supabase, Firebase, IPFS, self-hosted WebSocket relay
2026-10-21	peerjs.com/	'Use our free cloud server or host your own PeerServer' (free signalling broker; relayed data still needs a TURN server)
