Derived from Agora's tier definition, which prices video by the aggregate resolution of all the streams a user subscribes to. The rows assume every stream arrives at full size; smaller windows and lower simulcast layers reduce the aggregate. VoltKit bills the highest media a participant sends or receives, so the number of streams received does not change its rate.agora.ioread 2026-10-24
One video rate covers 480p, 720p and 1080p at 30 fps with HD audio included; voice comes at a standard and an HD rate; 60 fps upgrades are charged only while 60 fps is delivered. Every rate is per 1,000 participant-minutes, recorded in seconds and billed per participant-second. The same list is on the pricing page, and pricing in India adds a participant-minute calculator and paying by UPI, card or net banking.
Each participant is billed one rate at a time: the highest of what they send and what they receive, recorded every 5 seconds and charged per second.

Billing units
Per-minute figures only compare when the minute means the same thing. Here is what each vendor counts, in its own words, with the page it comes from.
The rate depends on the resolution a participant receives. Agora, Tencent RTC and Stream add up the pixels of every stream arriving at once.
Any video costs the same per participant-minute; some vendors publish a lower audio-only rate.
A per-minute rate, with downstream bandwidth billed per GB on top, inside a monthly plan.

VoltKit RTC has no bandwidth line, no plan fee and no MAU price for chat. Chat comes with every room, and chat messages and chat-only connections are not charged; API calls, tokens, webhooks and in-app music are not billed either. See what is billed and the chat guide.
What you build
One room model carries calls, voice rooms and interactive live rooms: audio broadcasting rooms and video broadcasting rooms where hosts and seated guests publish and everyone else in the same room watches or listens, with chat beside them.
Interactive live rooms: hosts and seated guests on air, the audience in the same room; not CDN broadcast.
5-seater, 9-seater, 12-seater or 20-seater: the seat count is your app's layout. The service sets no limit on how many people publish in a room, so your app decides how many seats it shows. 1v1 PK, 1-vs-N PK, 2v2 team PK and family PK are app logic built on rooms, chat and the promote-and-reconnect recipe; VoltKit has no PK module.
More on the product at VoltKit RTC. Read Rooms, Group audio rooms and Chat for the calls behind each of these.
Migration
The concepts carry over almost one to one: an Agora channel is a VoltKit room, a uid is an identity (a string you choose), a broadcaster is a host or co-host, and an audience member is a viewer. Your backend replaces Agora's token builder with two REST calls, and the app replaces RtcEngine with one StreamClient per call or room.
The honest difference is where decisions are made: roles, moderation and room lifetime are enforced by the VoltKit service from what your backend signed into the token, not by the client. A modified app cannot promote itself, unmute itself after a force-mute or ignore a removal.
| Agora | VoltKit RTC |
|---|---|
| App ID + App Certificate | API base URL + API secret (server only) |
| Channel name | roomId (create it with PUT /v1/rooms/{roomId}) |
| uid (int) | identity (your user id, a string) |
| RTC token from the token builder | room token from POST /v1/rooms/{roomId}/tokens, with the role inside |
CLIENT_ROLE_BROADCASTER | host (moderates too) or cohost |
CLIENT_ROLE_AUDIENCE | viewer |
setClientRole on the client | the host calls promote(identity, role); the server enforces it |
| RTM (messaging) | built in: sendMessage / onMessage on the same connection |
| Agora RtcEngine | VoltKit StreamClient |
|---|---|
RtcEngine.create(config) | StreamClient(context, wsUrl, token) |
joinChannel(token, channel, uid, options) | connect(metadata) |
leaveChannel(), RtcEngine.destroy() | close() |
muteLocalAudioStream(muted) | setMicEnabled(!muted) |
setupRemoteVideo(VideoCanvas) | attachVideo(track, renderer) |
renewToken(token) | updateToken(token) |
The full table, callbacks included, is in Migrating from Agora. Remote tracks arrive without subscribe calls, audio routing follows headsets by itself, and a token is refreshed by the service during the session, so updateToken is rarely needed.

| Server SDK | Make sure the room exists | Mint a token for a user |
|---|---|---|
| Node.js@voltkit-rtc/server | rtc.ensureRoom({ roomId, hostIdentity }) | rtc.createToken({ roomId, identity, role }) |
| Pythonvoltkit-rtc-server | rtc.ensure_room(room_id, host_identity=...) | rtc.create_token(room_id, identity=..., role=...) |
| Gogithub.com/voltkit-rtc/voltkit-rtc-server-go | client.EnsureRoom(ctx, voltkit.EnsureRoomParams{...}) | client.CreateToken(ctx, voltkit.CreateTokenParams{...}) |
| PHPvoltkit/rtc-server | $rtc->ensureRoom(roomId: ..., hostIdentity: ...) | $rtc->createToken(roomId: ..., identity: ..., role: ...) |
| Javain.voltkit:voltkit-rtc-server | rtc.ensureRoom(roomId, hostIdentity) | rtc.createToken(roomId, identity, role) |
Issue tokens from your backend builds the whole endpoint, with your own user authentication in front of it.

iOS preview notesLimits
Agora's allowance, per its RTC pricing doc read on 2026-10-24: 10,000 Standard Minutes a month on the Free package (an HD video minute uses 4 Standard Minutes, a Full HD minute 9). What happens after that depends on the page: Agora's RTC pricing doc gives the Free package's overuse policy as service suspension until a top-up or postpaid billing. Agora's billing-policy page says minutes beyond the free allowance are charged. Once a paid package is bought, the monthly free allowance stops. Both pages are linked above.
From Agora's pricing pages (docs.agora.io, read 2026-10-24): Video is priced by the aggregate resolution of all the streams a user subscribes to: HD up to 921,600 pixels, Full HD up to 2,073,600, 2K up to 3,686,400, and 2K+ above that. A Standard Minute is usage multiplied by a coefficient: audio 1, HD 4, Full HD 9, 2K 16, 2K+ 36. On VoltKit, each participant is billed one rate at a time: the highest of what they send and what they receive, recorded every 5 seconds and charged per second.
There is no single answer, because vendors count different units: Agora, Tencent RTC and Stream price video by the aggregate resolution a participant receives; Twilio Video, 100ms, Daily, Vonage and Cloudflare RealtimeKit charge one rate for any video; LiveKit Cloud adds a bandwidth meter and a plan fee to its per-minute rate. The table on this page lists every rate as published on 2026-10-24, with its URL. VoltKit RTC: ₹99 (≈ $1.04) per 1,000 participant-minutes for Full HD video at the list prices published on 2026-10-24 by the vendors compared.
New accounts get a one-time testing trial: 2,500 participant-minutes on your first project, at any quality; up to 25 people per room until the first paid recharge. The number is read live and changes for campaigns. Any free minutes VoltKit sets for a project are shown on the project's Overview tab.
Not on VoltKit: every room has a chat channel, and chat messages and chat-only connections are not charged, within a daily allowance that grows with your live usage. For Agora, our research noted that its monthly allowance excludes its Chat SDK; that line is unverified, so check Agora's pricing page before relying on it.
Yes. The migration guide maps Agora's concepts (channel to room, uid to identity, broadcaster and audience to host, cohost and viewer, RTM to the built-in chat) and lists RtcEngine calls beside their StreamClient equivalents, with Kotlin examples; the Flutter and JavaScript SDKs use the same names. Your backend replaces Agora's token builder with two REST calls.
No. VoltKit video goes up to 1080p: one rate for 480p, 720p and 1080p at 30 fps with HD audio included, and 60 fps upgrades at 480p, 720p and 1080p, charged only while 60 fps is actually delivered. Agora lists Video 2K at $15.99 and Video 2K+ at $35.99 per 1,000 minutes (agora.io, read 2026-10-24).
Each vendor figure is the list price published on 2026-10-24 at the URL beside it; the figures are re-checked monthly and the check date is printed on the page. VoltKit's rates are read live from its price list, so they are today's.
Voice rooms, video calls and interactive live rooms with chat, from one prepaid wallet in rupees. Your backend mints the tokens; the browser, React, Flutter and Android SDKs join the room.
