Same protocol. Different bill.
Pricing models differ: some bill per GB, some sell monthly bundles. Each provider's public list price is shown in the terms they publish, so you can compare against your own traffic.

Dollars per TB of relayed traffic, normalised from each provider's own published list price on 2026-09-16. Billing models differ — each is named under the provider. Where a provider publishes nothing on a row, the table says so rather than guessing. Follow the source links for current figures.
ExpressTURN: The $9 Premium plan includes 5,000 GB. ExpressTURN publishes no overage rate and no pricing above that plan, so the cost of exceeding 5 TB in a month is not knowable from their site.

How to compare for your app
A per-GB rate only means something once you know how much of your traffic is relayed.
Estimate relayed sessions
Commonly 10–20% of sessions need a relay, and more on corporate and cellular networks. Your own mix is the only number that matters.
Multiply by data per session
Voice uses roughly 25–30 MB per hour in each direction; 720p video about 1 GB. These are estimates from codec bitrates, not measurements.
Check the fine print
Which direction is billed, whether TLS on 443 is included, and whether the regions you need are actually offered.
