AI support that a team can actually run
Ask support a question as a customer, then see the same conversation land on the operator side.
One session, two surfaces, and a record of what happened.
Embed on your help centre, pricing page, or in-app support panel.

- Support is ready for the customer

That entire dashboard is one tag and a key
All six widget types install exactly this way. Build one in the dashboard, paste these four lines, and replace a single value. There is no SDK to learn, no build step, and no backend to stand up.
The operator console — live sessions, conversation replay, human takeover.

Testable Proof
Five capabilities. All running here.
These are working paths, not concept screens: load the widgets, create a transcript, join a translated room, talk to a multimodal agent, or call an AI agent by phone.

Numbers, not quotes
Free to start. Built for the ceiling.
Every figure below is published in the product, pricing, and docs — not a testimonial, and not a number we made up for this page.
Published scale
Start small without choosing a small ceiling.
These are decision points you can verify in product, pricing, and implementation materials.
A real starting allowance for testing live workloads.
A room path for large, participatory sessions.
A separate delivery path when the audience becomes the scale.
The service level the platform is engineered around.
Start at the level that creates value. Keep every deeper option open.
MediaSFU is useful before engineering starts and remains useful after the product becomes fully custom. Pick the outcome your team needs today.

Start with prebuilt room UI or use headless controls across web, mobile, native Android and iOS, and Unity.
What you getCustomize deeply without replacing the platform.
Ten production SDK pathsReact / React Native / Expo / Flutter / Angular / Vue / Kotlin / Android / Swift/iOS / Unity
Compare SDKs Good, fast, cheap. Pick two.
That rule is a constraint on building it. Every corner below was already paid for by somebody else.
FastBecause you are not building it.Six finished rooms open in this tab. Six widgets are one script tag. Vibe Studio writes the project around them.
- 6 showcase rooms
- 6 embeddable widgets
- no account for any of it
- published rates
- no seat licences
- 50,000 free minutes
- 10 open-source SDKs
- full UI or headless
- cloud or self-hosted
The catch, since there is always one. If you want a room nobody has built before, you build it. Take the SDKs, go headless, and wire your own surface — that path is slower, and it is still cheap.
