REALTIME MESSAGING · INCLUDED WITH EVERY TURN PLAN
Concurrent connections and messages per month, included in the plan price.
| PLAN | CONCURRENT CONNECTIONS | MESSAGES / MONTH | OVER THE ALLOWANCE |
|---|---|---|---|
| FreeEvery account | 100 | 100k | Hard capNo overage charges |
| GrowthTURN 150 GB · $99/mo | 1,000 | 5M | $2.50 / million messages$0.01 / extra peak connection |
| BusinessTURN 500 GB · $199/mo | 5,000 | 25M | $2.50 / million messages$0.01 / extra peak connection |
| EnterpriseTURN 2 TB and up | 20,000 | 100M | $2.50 / million messages$0.01 / extra peak connection |
Paid-plan overage is drawn from your account balance and is on by default. Connection overage is charged once per billing period for each connection your peak concurrency reaches above the allowance. The allowance becomes a hard cap if you switch overage off in the dashboard, or if your balance runs out with auto-recharge off. The free tier is hard-capped. Limits and quotas

EXCEPTIONAL SERVICE
Our customer service team includes engineers and developers experienced in WebRTC who can handle your technical and non-technical requests quickly.
POWERFUL APIS
With Metered TURN Server's robust REST APIs, you gain full control of TURN Server management.
DASHBOARD & ANALYTICS
Use the Metered TURN Server dashboard to manage user credentials, view detailed usage stats and manage billing information.
10 — SIGNALLING
TURN Relay carries the media. Signalling establishes the session. One integration covers both halves of the job: getting your peers to find each other, and carrying the media once they do. Signalling is included with every TURN plan.
Every Metered TURN plan includes Realtime Messaging: a managed WebSocket layer that handles SDP and ICE exchange between peers. Session establishment is provisioned alongside the relay rather than procured separately.
WHAT YOU DON'T HAVE TO BUILD
Paid TURN plans carry a bundled Realtime Messaging (Signalling) allowance, and overages are available if you go over it. Accounts without a paid TURN plan use the free tier. See the allowance per plan
11 — CREDENTIAL MANAGEMENT
Credentials are created from your backend with an optional expiry and an optional label. Any credential can be disabled, re-enabled, deleted, or deleted in bulk by label.
01 · CREATE
Returns a username, a password, and a credential-scoped API key.
02 · LABEL
labelA free-text string on the credential. Filter the credential list by it, update it, or delete by it.
03 · EXPIRE
expiryInSecondsThe credential auto-disables when it elapses. No minimum, no maximum. Omit it and the credential does not expire.
04 · REVOKE
Delete by label removes every active credential carrying that label and returns the count.
KEY SCOPES
secretKey
ACCOUNT · SERVER-SIDE ONLY
Creates credentials, lists them, and manages projects and usage. Never exposed in front-end code.
apiKey
CREDENTIAL · FRONT-END SAFE
Issued with each credential. Works with one endpoint only — Get Credential, which returns that credential's ICE servers array.
projectApiKey
PROJECT · SERVER-SIDE
Stands in for the secret key on project endpoints. Can be regenerated, which invalidates the old one immediately.
GETTING IT TO YOUR APP
Expiring credentials. Your backend creates one,
gets back a username, password and a credential-scoped
apiKey,
and hands that key to the front end. The browser exchanges it for the ICE servers
array. When the deadline passes, the credential auto-disables.
Non-expiring credentials. Nothing needs re-creating, so the front end can hold the scoped key and fetch its ICE servers directly. Your secret key stays on the server either way.
From the dashboard. Every credential has a Show ICE Servers Array button that gives you the finished configuration to copy.
Every route returns the same complete array — STUN, plus TURN over UDP and TCP on ports 80 and 443, and TURNS over TLS.
curl -X POST \
"$API/api/v1/turn/credential?secretKey=$SECRET" \
-H "Content-Type: application/json" \
-d '{
"expiryInSeconds": 14400,
"label": "customer-acme"
}'
# Both fields are optional.
# Returns: username, password, apiKeyIN THE DASHBOARD
Listing credentials over the API is available on every plan, the free trial included.
12 — DATA RESIDENCY
By default, traffic routes to the server nearest each user. Or name a region: media for your German customers remains in Germany, media for your Canadian customers remains in Canada. One account, one integration.
Region control is applied at the credential level rather than the account level. Name a region when you request that credential's ICE servers and it relays through that region. Omit it and traffic routes to the nearest available edge automatically.
A single account can satisfy conflicting residency obligations concurrently — per tenant, without duplicate accounts, parallel environments or a forked integration to maintain.
Full region list and endpoints# Relay this credential from a named region
curl "$API/api/v1/turn/credentials?apiKey=$KEY®ion=eu"
# Omit it for the nearest server to the user
curl "$API/api/v1/turn/credentials?apiKey=$KEY"
# Both return the full ICE servers array.STATIC IP ALLOWLISTING
We publish the relay IP addresses for every region, as individual addresses and as ranges, so your network team opens exactly what your policy allows — no guesswork, and nothing opened on faith.
How much they open depends on how you route. Automatic geo-routing can place a session in any region, so the allowlist has to cover every region we operate. Pin a credential to a region and the list narrows to that region's addresses alone.
Available on every plan, the free trial included.
13 — THROUGHPUT
Metered does not impose a throughput limit on individual TURN allocations. Available bitrate is governed by the client's own connection.
4K video
A single 4K stream through the relay encounters no platform-imposed limit, and neither does a multi-track session carrying several of them concurrently.
Remote rendering
Remote-rendered frame buffers and AR/VR workloads are bandwidth-intensive by design. The relay is not the constraint on them.
AI video
Sessions carrying multiple tracks into an inference pipeline relay at whatever rate the client is able to sustain.
WHY THE COMMITMENT HOLDS
An uncapped allocation is only meaningful if the underlying network can carry it. Metered operates 100+ edge points of presence across 31+ regions.

14 — COST CONTROL
Fund the account in advance. Relay usage draws down that balance and cannot exceed it, unless you set a threshold and an amount to top it up automatically.
PREPAID BALANCE
USAGE VISIBILITY
Attributing a given day's consumption to a specific customer is a single API call. Daily relay usage is available per credential for the preceding three months, with your own labels present on every record.
Set a threshold and a top-up amount, and the account keeps itself funded. Your relay runs continuously while the balance looks after itself.
The dashboard projects how long the current balance lasts at your present rate of consumption, so a top-up is a decision you make early rather than a surprise.
You set the ceiling; auto-recharge respects it. Your overage rate and every top-up are shown alongside the balance, so nothing about the bill is inferred.
15 — SUPPORT
Every paid plan includes emergency phone support. Dial in with your PIN and you're talking to the engineers who run the network.
Email support is for everything else, and it is available on every plan including the free trial — integration and configuration questions, credential and API behaviour, billing and payment queries, or anything else that needs a considered answer rather than an immediate one.
AVAILABILITY BY PLAN
Email support covers every plan and every kind of question. The free trial otherwise includes the paid feature set, global region access included, with emergency phone support the single exception. Both channels are staffed 24/7 by WebRTC engineers.
16 — ANALYTICS AND OBSERVABILITY
Relay traffic is only useful if you can attribute it. Usage breaks down by credential, project, country and transport — over windows from the last five minutes to the last ninety days.
GEOGRAPHY
Relay traffic by country, with client counts and share of total. Each row carries its own trend line over the selected window.
ATTRIBUTION
Credentials ranked by bytes, with share of total and a sparkline. The same breakdown exists per project, so a tenant's consumption is one glance away.
TRANSPORT
The split across UDP, TCP and TLS — so you can see how much of your traffic is traversing restrictive networks, and plan for it.
PEAK HOUR
A thirty-day heatmap plots session activity as day of week against hour of day. The busiest cell is named outright — the day, the hour, and the sessions it carried — and hovering any other cell reads back its own count.
The headline strip carries the same question in bytes: the single hour that relayed the most data in the selected window.
PEAK
The hour that relayed the most data in the window.
CREDENTIALS IN USE
Distinct credentials that actually relayed, not merely those issued.
PERIOD
Every figure carries the window it was measured over.
LIVE
The overview lists sessions from the last five minutes as they arrive, each with its type, the region that served it and how long it has been running. Confirmation that a deploy is relaying arrives in seconds, not at the next daily rollup.
TIME RANGE
Last hour, day, week, month or ninety days — each window compared against the preceding one of equal length, so a change in consumption is visible rather than inferred.
17 — INTEGRATION
Metered publishes full API reference documentation for your engineers, and machine-readable reference files so AI coding assistants generate integrations against current API behaviour rather than recalled training data.
Provide our TURN reference file to Claude Code, Cursor, GitHub Copilot, ChatGPT, GPT Codex or Windsurf and the assistant integrates Metered TURN into your application from current documentation.
OPENAPI SPECIFICATION
An OpenAPI specification is published alongside it: import it into Postman, generate a typed client in your language, or incorporate it into contract testing as part of your release process.

INFRASTRUCTURE
Private backbone linking global TURN servers for ultra-low-latency communication between continents
One unique advantage of our TURN infrastructure is a specialized high-speed backbone that links our global TURN servers. For example, if one user is in London and another in New York, each connects to their nearest TURN server. These TURN servers are then interconnected via our private, high-speed backbone—ensuring ultra-low-latency, high-throughput communication between continents.
NETWORK TOPOLOGY
Low latency media relayed via private backbone
Consistently lower latency for long-distance calls across continents
Stable performance even when public internet routes are congested
High reliability for mission-critical real-time applications
Whether you're running an international video conference, a collaborative AR/VR session, or a cross-continent multiplayer game, the specialized backbone ensures your users experience the smoothest, most responsive connection possible.
