We build custom video calling and chat apps on WebRTC, mediasoup, and LiveKit: 1-on-1 and group calls, recording, screen share, and chat, on web, iOS, and Android. First working build in 6-8 weeks, from $6K. You own the code, with no per-minute platform bill.
We build video chat and calling apps for founders launching a product, and for teams adding calls to an app that already has users. The hard parts, group calls, mobile, recording, and weak-network quality, are the ones we have shipped before, not learned on your budget.
A CPaaS like Twilio or Agora ships a demo fast, then bills per minute and owns your media path. A generalist agency learns WebRTC on your budget. A team that has shipped video apps already knows the group-call, mobile, and recording traps, and hands you the code.
Already have an app and users? We add calling to it. Starting from zero? We build the whole product. On a CPaaS and watching the bill climb? We migrate you off. Either way the code and the data are yours. New to the trade-offs? See WebRTC architecture for production systems.
The first decision in a video app is not code, it is call shape: 1-on-1, small group, or large room. That choice sets the topology and the cost. Here is how we go from idea to a shipped app.
We map your calls, group sizes, platforms, and any compliance, then pick the topology (P2P, SFU, or MCU) and whether to self-host an SFU or use a CPaaS, with no house bias.
We design the call experience (lobby, join, in-call controls, chat) and build signaling, rooms, and token auth, so joining a call is one tap, not a support ticket.
Web, iOS, and Android on the chosen SDKs (mediasoup, LiveKit, react-native-webrtc), with screen share, recording, and the features your product needs.
coturn (TURN/STUN), simulcast, and SVC so calls connect on hotel wifi and 4G and degrade gracefully instead of dropping. This is where most DIY apps fail.
Store and CI/CD release, load tests to your concurrency target, recording storage, and dashboards. You get the code and the deployment.
The result holds sub-300 ms glass-to-glass on a real network, and the architecture matches your call sizes, not a vendor's upsell.
A business video conferencing app with up to 200 video participants per call (1,000 audio-only), AES-256 encryption, and face-recognition meeting entry, on web, iOS, Android, and PWA. Used by PwC and MTS; top-30 on G2.
A WebRTC and FreeSWITCH conferencing SaaS combining Zoom, Calendly, and DocuSign, with SIP/VoIP dial-in from a phone and Instasign in-call document signing.
A peer-to-peer WebRTC video chat app we built and shipped to the App Store and Google Play: one-tap Apple or Google login, room-number join, mobile screen share, and an incognito mode.
A video platform (up to 20 on a call, 500 in a webinar) that analyzes calls in real time, with Google Meet, MS Teams, and Zoom integration. Raised SEK 21M (about $2.25M) in 2025.
A streamer app with free group broadcasts and paid 1:1 video sessions billed per minute, plus in-app currency and gifting. 100K+ downloads on Google Play.
The same WebRTC core powers HIPAA-ready telehealth visits and live virtual classrooms, with recording, waiting rooms, and screen share built in.
A CPaaS SDK is the right call for a quick test or a feature you will never scale. Build a custom app when video is core to your product, when the per-minute bill stops making sense, or when the call has to look and behave like yours. Here is the honest split.
We design and build the whole video app end to end, web and mobile. You get the product and the code.
You have an app and users; we add calling, conferencing, or live video into it without a rebuild.
A pod (engineers, lead, QA) that owns your video roadmap month to month, scoped to your plan.
A stalled build, a buckling app, or a CPaaS bill out of control. We stabilize calls, then move you onto infrastructure you own.
Fixed-scope starting points for a custom build. Prefer a dedicated team, or adding video to an existing app? That is a monthly rate, scoped on the call.
Adding video to an existing app and dedicated-team engagements are billed monthly per the team you need. Infrastructure (SFU hosting, TURN, recording storage) is billed at cost, with no markup from us.
Before you commit a budget, we will help you pick the call architecture and catch the scaling and mobile traps early.
Competitor analysis, core feature definition, monetization modeling, and a full launch blueprint — delivered within a week. Written by engineers who'll build what they plan.
An independent review of your system's technology choices, structural components, and workload fit — with a plain verdict on what's working, what's a liability, and exactly what to change to reach your goal. Delivered within a week.
A full audit of your code with every issue documented, evidenced, and located — exact file, exact line. Plus a system architecture review and a prioritized fix roadmap. Not a consultant's opinion. A case file. Delivered within a week.
A specialist review of your video or streaming product covering latency, media server architecture, WebRTC, playback reliability, real-time chat, and scalability. Every finding is specific, located, and fixable. Delivered within a week.
We are not a generalist shop with a video service line. Live video and audio is what we have built since 2005, across consumer chat, business conferencing, telehealth, and classrooms. One of the apps on the App Store is ours.
Two decades of real-time video, not a recent service offering.
iMind runs 200-party conferencing for PwC; our own Tunnel video chat app is on the App Store and Google Play; Alve.chat passed 100K+ downloads.
Group calls, TURN and NAT traversal, simulcast and SVC, mobile, and recording: the edge cases that sink first-timers.
One team for web, iOS, and Android, so the call behaves the same on every device.
AES-256, HIPAA, and SOC 2 patterns in production, not slideware.
Code, design, and deployment are yours. We hand off cleanly or stay embedded, with no lock-in.
What is video chat app development?
How long does it take to build a video chat app?
How much does it cost to build a video calling app?
Should I use WebRTC or a CPaaS like Twilio or Agora?
Can you add video calling to my existing app?
How do you support group video calls?
Will the app work on iOS and Android?
Can the app handle recording, screen share, and chat?
Is a custom video app HIPAA compliant or end-to-end encrypted?
Do we own the code and the app?
Tell us the call sizes, the platforms, and where it has to run. We will pick the topology, name the stack, and give you a build plan, a price, and a timeline, in one call. Building one-to-many broadcast instead? See scalable video streaming. Need a WebRTC engineering team for an existing build? See WebRTC development.
