WebRTC Development Company That Works at the Protocol Level — Not Just the SDK.

Trembit provides end-to-end WebRTC development services across three areas: custom (greenfield) WebRTC development — architecting and building new real-time video and voice products; WebRTC scaling and media server engineering — re-architecting the media layer for concurrency and migrating off CPaaS providers; and WebRTC rescue and stabilization — diagnosing and fixing failing video platforms at the protocol level. We work across all major media servers (Janus, Jitsi, mediasoup, LiveKit, Kurento) and cover the full stack from signaling and TURN infrastructure to client SDKs on web, iOS, and Android.

The clearest signals are: a call drop or connection-failure rate above ~2–3%; quality that collapses when you add participants (works at 5, breaks at 15); CPaaS bills growing faster than your user base; a video feature that’s been “almost done” for months; or a live platform your current team can’t confidently debug because the failures are below the SDK — in ICE, TURN, SDP, or codec negotiation. If a compliance audit is approaching and your video stack keeps dropping calls, that’s the strongest signal of all. A technical scoping call with one of our engineers will tell you which of these you’re facing.

It depends on scope and engagement model. Greenfield builds run as a dedicated team or a fixed-price engagement scoped to a defined MVP or feature set; rescue and scaling work is usually Time & Materials, because the exact fix emerges during the first two weeks of diagnosis. The main cost drivers are your target scale, your architecture (P2P vs. SFU vs. a custom media server), compliance requirements, and how much of the stack already exists. We give you a firm, itemized estimate after a technical scoping call — and for rescue or scaling, a prioritized plan within two weeks before you commit.

Yes — this is one of our core capabilities. Many of our engagements begin as rescues: we inherit a live but failing video product, assess the codebase, and deliver a root-cause diagnosis within two weeks. We fix the actual problem at the protocol level (ICE, TURN, SDP, codec negotiation, media server configuration) rather than applying patches, then document the architecture and transfer knowledge to your team. If a codebase is genuinely too far gone, we’ll tell you honestly and recommend a targeted rebuild of the media layer while preserving your application layer. See our WebRTC work for examples.

It depends on your use case and scale curve. Peer-to-peer (P2P) is ideal for privacy-first 1:1 calls with no media server in the path — the architecture we used for KBV-certified psychotherapy video. SFU (Selective Forwarding Unit) is the standard choice for scalable group video, forwarding streams without re-encoding. MCU (Multipoint Control Unit) mixes streams server-side, useful for low-end client devices or broadcast scenarios at higher server cost. We help you choose during a technical scoping call — and for a standalone documented blueprint, see our architecture consulting.

We assess your current usage, design an owned-infrastructure architecture (typically an SFU on cloud or data-residency-specific hosting), and execute the migration incrementally without disrupting live users. The result is protocol-level control your roadmap needs and a cost structure that scales with your business rather than per-minute pricing. We run the old and new stacks in parallel until the migration is validated. For a standalone build-vs-buy decision first, see our WebRTC consulting.

Yes. We built the first KBV-certified psychotherapy video platform in Germany and have delivered HIPAA- and GDPR-compliant real-time platforms. Compliance is architected at the protocol level — encryption, media routing, and data residency designed to survive review — not retrofitted.
