Aeion Realtime vs Twilio Video, Daily.co, Vonage Video API

The math that kills SaaS margins:

``` Twilio Video pricing: Video: $0.00167/participant/minute Audio: $0.0008/participant/minute TURN: $0.0004/participant/minute Recording: $0.003/minute Transcription: $0.02/minute

Scenario: 100 active users, 50 hours/month each

Total participant-minutes = 100 × 50 × 60 = 300,000/minutes/month Video: 300,000 × $0.00167 = $501/month TURN (30% of users): 90,000 × $0.0004 = $36/month Recording: 300,000 × $0.003 = $900/month Transcription: 300,000 × $0.02 = $6,000/month Voice Insights: $3,000/month (minimum)

Total: $10,437/month just in Twilio ```

That's $125,244/year. For the same infrastructure you could run a dedicated Hetzner AX82-NVMe (AMD Ryzen 9 7950X, 128GB RAM, 2× 2TB NVMe) at $89/month. Even adding 3× LiveKit nodes for horizontal scaling at $89 each = $356/month total. You save $124,888/year by self-hosting.

Aeion Realtime:

Hetzner AX82-NVMe: $89/month LiveKit embedded: free (no per-minute fees) Whisper.cpp transcription: free (local) Recording: VPS storage (unlimited within disk) Total: $89/month for unlimited participants

The VPS that runs Aeion OS already handles your web server, database, Redis, and background workers. Adding LiveKit to the same VPS adds zero hardware cost — only LiveKit configuration time.

Daily.co's strengths: Cleaner API than Twilio, better developer experience, reasonable pricing.

Daily.co pricing:

Video: $0.00125/participant/minute Recording: $0.003/minute Transcription: $0.02/minute HIPAA: $2,500/month add-on

100 users × 50 hours/month with Daily.co:

Video: $3,750/month Recording: $900/month Transcription: $6,000/month HIPAA: $2,500/month Total: $13,150/month

Why "better pricing" is still bad: Whether it's $10K/month (Twilio) or $13K/month (Daily.co), you're still paying variable per-minute fees that scale with usage. Growth = higher bills. Success = higher bills. The financial model is fundamentally at odds with the product's value proposition.

Aeion Realtime: Fixed cost. Growth = same bill. Success = same bill.

Daily.co's other limitations:

• No AI participants
• No pre-built agents (Review Producer, AI Tutor, etc.)
• No multi-tenant isolation (shared infrastructure)
• No self-hosted LiveKit option
• No BYO TURN server
• Basic audit logging (no HMAC signing, no 7-year retention)

Daily.co is the best of the per-minute vendors. But "best of a bad model" is still a bad model for serious SaaS businesses.

Twilio, Daily.co, and Vonage are video infrastructure. They provide the pipe — nothing more. You still need to build everything that happens inside the session.

Aeion Realtime is the full stack:

Universal room / peer / JWT session primitive ↓ Every session gets: cross-module attach, compliance profiles, participant tracking ↓ AI participants with summon / dismiss lifecycle ↓ LLM turn orchestration with 30s checkpointing ↓ Tool dispatcher routing 89 MCP tools ↓ Agent takes real actions inside the session

The difference in capability:

• Twilio: User joins video call. Someone takes notes manually. Notes are written after the call. Action items get lost.
• Aeion Realtime: User joins video call. AI agent joins simultaneously. Agent watches the conversation, takes notes in real-time, creates follow-up tasks in CRM, flags action items, sends summary after the call.

89 MCP tools means the agent is useful in every context:

• Collab meeting: agent creates notes, updates deal stage, sends follow-up email
• Helpdesk session: agent classifies issue, suggests KB articles, escalates if needed
• LMS class: agent answers questions, tracks comprehension, generates class report
• Telehealth: agent writes clinical notes, surfaces patient history, creates follow-up

This is not a chatbot in a sidebar. This is a full participant in the session that takes actions via the same tools your team uses.

20-30% of users are behind restrictive NATs. STUN alone doesn't work for them. They need TURN (relay). Twilio and Daily.co charge per-minute for TURN.

Coturn self-hosted (included in Aeion Realtime):

``` Listening: port 3478 (UDP + TCP) TLS: port 5349 (DTLS) Realm: aeion External IP: auto-detected

Throughput: 1Gbps on a modern VPS Cost: $0/month (coturn is open-source, runs on your VPS) ```

Circuit breaker behavior:

``` coturn crashes → supervisor restarts (up to 5 times/hour) After 5 crashes in 1 hour → circuit opens → Emits: realtime.coturn.circuit_opened → Clients fall back to STUN-only → Admin alert sent

Recovery: manual coturnctl restart OR auto after 1-hour cooldown (half-open test restart; returns to normal once stable 5+ min) ```

Cloudflare Calls fallback (optional):

bash CF_TURN_KEY_ID=... CF_TURN_API_TOKEN=...

When coturn is unavailable (cooldown period), Aeion can fall back to Cloudflare Calls TURN credentials. Short-lived credentials (1-hour TTL), no per-minute cost.

Per-tenant TURN override: any tenant with their own TURN infrastructure can configure it directly — once set, that tenant's sessions use your TURN server instead of the platform default, with no code required.

BYO LiveKit cluster: any tenant can point Realtime at their own externally hosted LiveKit instance instead of the embedded one — just supply your instance's API URL, WebSocket URL, and credentials in the admin panel.

Twilio HIPAA: BAA available at $5,000/month extra. Shared infrastructure with non-HIPAA tenants.

Daily.co HIPAA: $2,500/month add-on. Shared infrastructure.

Aeion Realtime HIPAA: set a session's compliance profile to "hipaa" and it's self-contained isolation from the start — encrypted, isolated recording storage; TURN traffic restricted to your own self-hosted relay (no third-party TURN); only BAA-covered AI providers permitted; 7-year (2555-day) retention; consent required before recording; every event audit-logged; end-to-end encryption available.

Key differences:

• Aeion Realtime: Self-hosted, per-tenant isolation, BYO storage backend
• Twilio/Daily.co: Shared infrastructure, vendor-controlled storage, per-tenant namespace only

GDPR-strict profile: EU-only recording storage with no US transfers; TURN traffic restricted to your self-hosted relay; only EU-data-resident AI providers permitted; 30-day default retention; consent required; every event audit-logged; all data stays in the EU; erasure requests processed immediately.

HMAC-SHA256 audit signing: every compliance event — including retention enforcement, like "HIPAA retention window expired: 1 recording deleted, 3 transcripts deleted" — is signed with HMAC-SHA256. The signing key rotates every 90 days (checked daily at 03:00 UTC), and rotated keys are kept for 7 years so old signatures remain verifiable.

Twilio/Daily.co don't offer this:

• HMAC-SHA256 signed audit logs
• 7-year key retention
• Per-compliance-profile enforcement
• GDPR-strict profile (EU residency, no US transfers)
• PCI compliance profile
