Aeion Realtime vs Twilio & Agora
Discover why telehealth startups, collaborative workspaces, and online education platforms are abandoning exorbitant per-minute API fees for a natively integrated, self-hosted WebRTC communications operating system.

Decisive Architectural Advantages
The End of the Metered Web
CPaaS providers like Twilio, Agora, and Pusher operate like archaic telephone companies, charging you for every minute a user is connected or every WebSocket message sent. This makes scaling video apps financially terrifying. Aeion Realtime deploys a highly-optimized LiveKit SFU natively onto your server. You pay $0 in variable software fees. You only pay for your standard cloud bandwidth, which is exponentially cheaper.
True Native OS Synergy
Building a video room with Agora requires maintaining a separate database table for room IDs and writing complex webhooks to figure out who joined. Aeion Realtime is built into the platform itself. Every session links directly to the CRM deal or Helpdesk ticket it belongs to. When the call ends, the recording and transcript are automatically attached to the correct business record with zero custom API code.
Free Edge Transcription
Cloud transcription APIs are incredibly expensive for long meetings. Aeion OS completely bypasses them by running Whisper.cpp natively on your own server. Get highly accurate, real-time transcripts and speaker diarization for absolutely free, protecting your margins on every call.
Autonomous Voice Agents
Try connecting a GPT-4 agent to an Agora audio stream. It requires stitching together three different SDKs, a Python server, and a text-to-speech engine. Aeion Realtime features native AI participants. With one click, you deploy an AI agent directly into the WebRTC mesh. Because the agent lives inside the OS, it has full contextual access to 89 MCP tools to read business data and execute tasks live on the call. The agent isn't a bystander taking notes — it summons and dismisses through a real lifecycle, its every tool call is metered against a monthly budget cap, and its conversation state is checkpointed every 30 seconds so a process restart mid-call resumes rather than drops.
Where Twilio & Agora Still Win
Honest comparisons cut both ways. The per-minute CPaaS giants are the right call in real situations, and pretending otherwise would waste your time:
- Programmable telephony (PSTN, SMS, phone numbers). Twilio's core business is the phone network — provisioning real dial-in numbers, sending SMS, bridging calls to the carrier PSTN. Aeion Realtime is WebRTC: browser- and app-native audio, video, and data. If your product needs a customer to dial a phone number, receive a text, or reach a session from a landline, that's Twilio's domain, not this module's.
- Zero infrastructure to run. Aeion Realtime is self-hosted — you supply a VPS, and the platform provisions and monitors coturn and LiveKit on it. Twilio and Agora run the servers so you never touch one. If you have no infrastructure and no appetite for one, the metered model buys you that.
- Global edge on day one. The big CPaaS providers operate globally-distributed media POPs out of the box. Aeion Realtime matches this by deploying regional nodes (or pointing at an external LiveKit cluster), but that's a deliberate configuration step, not a default.
- Sub-100-hour hobby projects. Below roughly 100 participant-hours a month, the per-minute bill is small and the fixed VPS cost isn't yet worth managing. The economics flip hard as you scale — but at proof-of-concept volume, reach for the fastest path.
The switch pays off when your volume grows, your compliance requirements harden, or you want the session to _do_ something — attach to a CRM deal, transcribe for free, host an AI participant — rather than just carry pixels.
Frequently Asked Questions
No. Aeion OS manages the LiveKit and Coturn processes for you. When you click "Initialize," the platform automatically writes the configuration files, generates the crypto keys, and launches the servers natively on your VPS.
Yes. Aeion Realtime supports a multi-VPS LiveKit architecture for massive fan-out, and it natively supports RTMP/HLS egress, allowing you to rebroadcast the internal WebRTC session simultaneously out to YouTube Live or Twitch.
No — and we won't pretend it does. Aeion Realtime is a WebRTC communications module: browser- and app-native audio, video, screen-share, and data sessions. It doesn't provision PSTN phone numbers or send SMS. It replaces Twilio Video, Agora, and Pusher (the per-minute WebRTC and pub/sub products), not Twilio's programmable telephony.
Recording can't start until every participant gives consent; a participant who declines is server-muted, and one who revokes mid-recording is muted immediately with everything after the revocation dropped. Sessions can run under HIPAA, PCI, or GDPR-strict compliance profiles that constrain storage location, TURN provider, and which AI providers are allowed. Every compliance event is HMAC-SHA256 signed. These profiles are compliance-ready controls you configure — formal attestations are your responsibility, on your own infrastructure.
Because sessions attach to a business object, a call linked to a CRM deal or Helpdesk ticket automatically files its recording, transcript, and participant history against that record — no webhook plumbing. Recordings are transcribed through an automatic fallback chain that tries free local Whisper.cpp first and escalates to cloud providers only if it fails.
