Need more than Scale?

Larger concurrency and bundles, a dedicated SLA, or regional data-residency requirements — we quote against your actual usage and constraints. There is no fixed list price; we price it from the volume you will really use.

Pay for What You Use — With a Ceiling You Set

On paid plans your service keeps running past the bundle and you pay only these rates. The Free plan has no overage billing — it stops at the limit instead.

※ Video, streaming and speech-translation minutes are user-minutes — a 10-minute call between 2 people uses 20. ※ Overage is billed per started block, rounded up — exceeding HD video by just 100 user-minutes still bills one full block ($9.99). ※ Every paid plan has a monthly spend limit — 3× the plan price by default, raisable to 10× in the console. Past it, new sessions pause while calls already in progress continue; raising the limit does not increase your bill, because you are always charged for actual usage.

Frequently Asked Questions

Learn why HyperBabel offers unmatched value compared to any competitor in the market.

How does HyperBabel's pricing compare to other API platforms?

Competitors like SendBird, PubNub, and Stream charge per MAU, so costs climb as your user base grows. HyperBabel does not bill per MAU. The $99 Basic plan includes 1M messages, 500K connection minutes, 500K characters of real-time AI translation, 3,000 user-minutes of 1:1 HD video, and 1,000 minutes of real-time speech translation. Group video calls and live streaming are available on Scale ($1,999) — we open those only where usage can be metered exactly. Where competitors make you combine three or four separate APIs, HyperBabel delivers this in one plan.

Detailed Competitor Comparison — Is HyperBabel really cheaper?

The table below compares HyperBabel's $99/mo Basic plan with what it would cost to assemble the same capabilities from competing APIs.

※ Competitor pricing is based on 2026 public rates. Assembling chat + translation + video + streaming from separate APIs can cost $1,500–$2,500+/mo. HyperBabel covers chat, AI translation, 1:1 HD video and speech translation in one $99 Basic plan — and adds group video plus live streaming in one $1,999 Scale plan.

💡 What does "Zero Egress" mean?

Egress refers to the outbound network transfer cost incurred when users download or view files, images, or videos stored on a server. Most cloud storage providers like AWS S3 and Google Cloud Storage charge $0.09–$0.12 per GB every time a user downloads a file — even though uploading is free. As your user base grows, egress costs can easily exceed the storage fees by 10x or more. HyperBabel eliminates this entirely through our global CDN infrastructure, offering 100% free egress. You only pay an ultra-low $0.03/GB for storage capacity alone.

What is Zero Egress? Are there hidden fees?

Yes, there are absolutely zero hidden fees. 'Zero Egress' means we have completely eliminated the massive outbound network traffic fees typically charged when users download or view files. While other cloud providers charge $0.09–$0.12 per GB for egress, HyperBabel's proprietary global distributed storage eliminates download costs entirely — you only pay an ultra-low $0.03/GB for storage capacity.

Why did you unify chat, translation, video, and live streaming into a single API?

Building a global service typically requires contracting separate Chat APIs (SendBird), Translation APIs (DeepL), Video/Streaming APIs, and Storage — costing thousands per month and months of integration work. HyperBabel unifies all of these into a single All-in-One API with one SDK integration. This saves up to 80% compared to assembling competitor APIs individually.

Will my service drop if I exceed the monthly quota?

It depends on the plan. On **paid plans (Basic and Scale)** metered usage — messages, translation, video, speech translation, channels and storage — is never interrupted; you are simply billed at the overage rates above. **The Free plan has no overage billing, so it stops at the limit instead** — we will not keep serving usage we have no way to charge for. Peak Connections is a **contractual limit**, not a kill switch — we do not drop connections when you exceed it. If you stay above it we will reach out and move you to a larger plan. The only place new sessions actually pause is your monthly spend limit — 3× the plan price by default, raisable to 10× instantly in the console. When it is reached only *new* sessions pause; **calls already in progress are not cut off.** Raising the limit does not increase your bill (you are always charged for actual usage).

Will my app face API rejections if tens of thousands of users rush in simultaneously?

Per-minute API rate limits are 60 requests on Free, 600 on Basic, and 3,000 on Scale. Under the hood, intelligent message queuing pools and streams requests safely, so short spikes do not create bottlenecks for global real-time communication.

What are the expected connection speeds for global users?

We guarantee ultra-low latency. HyperBabel's proprietary Global Edge Network is distributed across all major continents to provide millisecond-level response times.

🌎 Americas / Asia

Achieves a global median latency of under 65ms.

Do you provide Webhooks?

Yes, Webhooks are included at no extra cost on every plan, Free included. When key events occur — video session start/end, chat message sent, live stream started, billing alerts, and more — HyperBabel automatically POSTs to your registered endpoint. Includes HMAC-SHA256 signature verification and up to 3 automatic retries with Exponential Backoff. Register in Dashboard → Webhooks.

Do you provide interactive Swagger API documentation?

Yes, we provide full Swagger UI (OpenAPI 3.0) documentation for every REST endpoint. Visit the Docs page and click the Swagger API tab — your JWT is auto-injected, so you can call and test any API directly from the browser without a separate client. Perfect for rapid prototyping and integration testing.

Is there a sandbox environment to try HyperBabel before integrating?

Yes. After signing up, access Sandbox Hub from the Dashboard and try every core feature hands-on — no API integration required: ① Real-time chat (create channels, send messages, live AI translation), ② Video calls (HD/FHD, join/leave, group calls), ③ Live streaming (start a broadcast, join as a viewer in real time), ④ Combined chat + video scenarios. Everything runs on the same production infrastructure, so what you test is exactly what your users will experience — including features your current plan does not include, so you can see what you would be buying before you integrate.
