WebRTC vs proprietary video platform
IT teams choosing video infrastructure often compare open WebRTC stacks with closed proprietary platforms (Zoom, Teams API, vendor SDK). This comparison focuses on architecture and governance, not feature marketing.
Short answer
WebRTC infrastructure gives you auditable components (SFU, TURN, API), deployable in France, integrable in your SI. Proprietary SaaS accelerates generic meetings but imposes vendor hosting, branding, and data policy. The trade-off is control vs speed-to-deploy.
Comparison grid
| Criterion | WebRTC infrastructure | Proprietary SaaS |
|---|---|---|
| Stack transparency | Auditable (open source possible) | Closed |
| Hosting | France, on-premise, your cloud | Vendor region |
| Guest branding | Your domain | Vendor domain |
| API scope | Full orchestration you control | Vendor-limited API |
| Network docs | Firewall guide, TURN location | Vendor-dependent |
| Migration | Possible with effort | High lock-in |
| Time to first meeting | Project scoping required | Fast for generic use |
| Best fit | Customer journeys, SI embed | Internal generic meetings |
When proprietary SaaS wins
- Quick internal adoption without integration project;
- Global interoperability out of the box;
- No sovereignty or deep customization requirements.
When WebRTC infrastructure wins
- Customer-facing branded journeys;
- GDPR / sovereignty documentation for DPO and procurement;
- CRM, portal, ticketing integration;
- Embedded video in existing applications.

Hybrid model (common in enterprise)
Many organizations keep Teams or Zoom internally and deploy sovereign WebRTC for customers and partners. leagora.io documents this split; products handle conversion per use case.
Does Agora use the WebRTC protocol?
Yes. Agora builds on WebRTC for real-time audio and video in browsers and native SDKs. Agora adds proprietary signaling, media optimization and global edge infrastructure on top of the standard.
| Aspect | Agora SDK | Self-hosted WebRTC (Leagora model) |
|---|---|---|
| Protocol base | WebRTC (with vendor extensions) | Open WebRTC (W3C / IETF) |
| Media path | Agora global cloud | Your SFU/TURN (France hosting) |
| Code audit | Closed SDK | Open source stacks auditable |
| Data residency | Vendor regions | Contractual per project |
| Integration | Agora SDK + REST API | Video API + your SI |
Teams evaluating “agora webrtc platform uses webrtc protocol” usually need to decide whether managed global SDK or controlled infrastructure fits governance requirements.
Agora vs self-hosted WebRTC: cost, latency and lock-in
| Criterion | Agora (managed SDK) | Self-hosted WebRTC |
|---|---|---|
| Time to first call | Fast (SDK integration) | Project scoping required |
| Latency | Optimized on Agora edge | Depends on SFU placement (low latency) |
| Cost model | Usage-based minutes | Infra + ops (cloud France or on-prem) |
| Lock-in | SDK and cloud dependency | Lower with open stacks |
| GDPR / sovereignty | Vendor DPA and regions | Full chain in EU |
| Customization | SDK UI and API limits | Full portal / CRM embed |
Neither model is universally better: Agora suits fast global SDK rollout; self-hosted WebRTC suits branded customer journeys, public procurement and DPO-driven residency requirements.

FAQ
Is WebRTC only for developers?
No: products like meeting.leagora.io provide ready interfaces. WebRTC infrastructure also supports custom builds via API.
Can WebRTC match SaaS meeting features?
Core real-time video, screen share, multi-participant: yes via SFU. Mass webinar passive audiences may combine WebRTC with CDN/HLS.
Does WebRTC require on-premise?
No: France-hosted managed cloud is the common model.
Key takeaways
- WebRTC = control, audit, integration, sovereignty.
- Proprietary SaaS = speed for generic internal meetings.
- Hybrid Teams/Zoom + WebRTC for customers is standard enterprise practice.
