Communication apps
Messaging, voice and video apps for teams, customers or communities, on web, desktop and mobile.
People judge a messaging app by small things: messages arriving instantly, in order, with the right notification and nothing lost. We build chat and calling apps on WebSockets and WebRTC, with delivery receipts, offline queues, push notifications and end-to-end encryption where privacy demands it.
What we build
- One-to-one and group chat with threads, reactions, files and read receipts
- Voice and video calls with screen sharing using WebRTC
- Push notifications through Firebase Cloud Messaging and Apple Push Notifications
- End-to-end encrypted messaging based on the Signal protocol
- Chat embedded inside your existing app, marketplace or platform
- Moderation tools, retention settings and message export for compliance

What it does well
Real-time delivery
Messages travel over persistent connections and arrive in order on every device.
Offline queue
Messages written without signal are kept and sent automatically once reconnected.
Calls built in
Voice, video and screen sharing run peer-to-peer, or through media servers for groups.
Private by default
End-to-end encryption can keep message content unreadable even to the server.
Smart notifications
Mentions, mutes and quiet hours decide which messages actually alert a person.
Compliance options
Retention rules, legal export and audit logs suit regulated business messaging.
Questions
Should we build chat or use a chat API service?
A hosted chat API gets you started quickly, and we can integrate one. Building your own makes sense at high message volumes, when per-user fees grow large, when data must stay in your region, or when you need features the service does not offer.
How many users can it handle?
That depends on design, not luck. We build connection servers that scale horizontally, load-test them with simulated users at your expected peak and beyond, and size the infrastructure from those test results rather than guesses.
Can calls work on poor mobile networks?
WebRTC adapts bitrate and resolution to the connection, and audio is prioritised over video when bandwidth drops. TURN servers relay calls through restrictive networks, and we test on throttled connections before each release.
