WebRTC Development Company That Works at the Protocol Level — Not Just the SDK.
We build, scale, and rescue real-time video and voice products — from peer-to-peer calls to custom SFU media servers handling thousands of concurrent streams. Our WebRTC development services turn unreliable video into infrastructure you can bet your product on.
Trusted by Teams Whose Products Depend on Video
Sound Familiar?
You're building a video product from scratch and can't afford to get the architecture wrong.
P2P, SFU, or MCU? Which media server? How do you plan for scale before you have users? The first 30 days of architecture decisions determine whether your platform scales gracefully or hits a wall at 50 concurrent users.
Your engineering team is strong — but WebRTC is a different world.
They ship React and Node.js confidently, but they can’t tell whether a dropped call is an ICE connectivity problem, a TURN relay misconfiguration, a codec negotiation failure, or a media server scaling limit. WebRTC failures live below the layer most teams work at.
Your video works for 5 people but breaks at 15.
Adding participants degrades quality for everyone. Your SFU isn’t configured for selective forwarding, simulcast, or bandwidth estimation — and nobody on the team knows how to fix it.
You've outgrown a CPaaS provider and the bill is killing your margins.
Twilio, Agora, or Daily got you to launch — but per-minute pricing doesn’t scale with your business, and you’re locked out of the protocol-level control your roadmap now needs.
The team that built your video stack is gone — and left no documentation worth reading.
Every patch is a guess, and a compliance audit is approaching. If your live platform is failing and you inherited the code, that’s a rescue — we take over and fix failing builds at the protocol level.
The Specialization Gap
Most development teams work at the API/SDK layer. When the problem lives below that — in the SDP offer/answer exchange, ICE candidate gathering, DTLS handshake, or media negotiation — they’re blind. Real-time video failures aren’t a general engineering problem. They’re a specialization problem. That’s the gap we fill.
WebRTC Development Services
Custom WebRTC Development (Greenfield)
For companies building a new real-time product.
We architect the right foundation from day one — P2P for privacy-first 1:1 calls, SFU for scalable group video, custom media servers where off-the-shelf won’t do. You get a platform designed for the scale you’re growing into, not the scale you have today.
- Architecture selection (P2P / SFU / MCU) matched to your use case and scale curve
- Custom signaling, TURN/STUN infrastructure, and media server deployment
- Simulcast, SVC, bandwidth estimation, and adaptive bitrate for real-network conditions
- Recording, streaming, transcription, and AI-pipeline hooks built in from the start
WebRTC Scaling u0026 Media Server Engineering
For companies whose video works but won't scale.
We re-architect the media layer for concurrency — selective forwarding, cascading SFUs, regional media routing — so adding users doesn’t degrade quality.
- SFU tuning and horizontal scaling (Janus, Jitsi, mediasoup, LiveKit, Kurento)
- Load testing, capacity planning, and cost optimization vs. CPaaS per-minute pricing
- Geographic media distribution and TURN relay optimization
- Migration off CPaaS providers (Twilio, Agora, Vonage) to owned infrastructure, end to end
WebRTC Rescue u0026 Stabilization
For companies with a live video product that's failing.
We inherit broken codebases and ship what the previous team couldn’t — diagnosing at the protocol level, fixing root causes, and handing back a stable, documented platform. This is one of our strongest capabilities.
- Codebase assessment and root-cause diagnosis within the first 2 weeks
- Protocol-level fixes (ICE, TURN, SDP, codec negotiation, media server configuration)
- Call-quality monitoring and drop-rate tracking in production
- Architecture documentation and knowledge transfer to your team

How We Engage
Technical Scoping Call (30 min)
A Trembit WebRTC engineer looks at your video architecture, asks the questions your team hasn’t been able to answer, and tells you what’s actually going on. No pitch deck — just a diagnosis. Want a standalone documented architecture blueprint or audit before you commit to a build? That’s our WebRTC consulting u0026 architecture review.
Assessment u0026 Diagnosis (Weeks 1–2)
For rescue and scaling work, we deliver a root-cause assessment and prioritized plan within two weeks. You know exactly what’s wrong, why, and what it takes to fix — before committing to a full engagement.
Build / Stabilize (Sprints)
We work in 2-week sprints with working software on a staging environment after every cycle. For rescue, critical fixes deploy first; for greenfield, we ship a thin vertical slice early to validate the architecture.
Monitor, Document u0026 Transfer
Production call-quality monitoring, drop-rate tracking, architecture documentation, and knowledge transfer so your team isn’t dependent on us for basic operations.
Ongoing Partnership
Most clients extend to an ongoing dedicated team (1–3+ years) for continued feature development on a now-stable platform.

What Our Clients Say
“Trembit has deep expertise and experience in WebRTC and Tokbox. They know the inner workings of the tech and were able to inherit our semi-functional code and get it to work where multiple prior teams couldn’t. It was a tough project and yet they breezed through it — we’d highly recommend them to anyone looking to build video tech.
“Their proactive team gets things done as if it were their own project, consistently delivering high-quality outputs. Trembit’s handy suggestions, adaptability, and customer-oriented approach stand out — but what really differentiates them is their ability to deeply understand business needs.
