How much does it cost to build an on-premise communication platform like Nucleus?

The budget depends on your required features: messaging, WebRTC calling, SIP integration, SMS, mobile apps, task tracking, and on-prem infrastructure. We can give a tailored estimate once we review your scope and deployment needs.

Can you build a system that runs fully inside our private network?

Yes. Nucleus was built exactly this way. We design and deploy solutions that run on your own servers (or private cloud), ensuring full control over data and compliance with strict regulations.

Can the platform support video and audio calls with WebRTC?

Absolutely. We have deep experience building WebRTC calling, including multi-device support, low-latency streaming, and SIP integration for regular cellular calls.

Is SIP calling difficult to integrate?

It requires careful backend architecture, but we've done it before. SIP support in Nucleus allows users to place and receive standard phone calls right inside the platform - we can build the same for your system.

Can you add task management or workflow tools to chat messages?

Yes. Nucleus includes message-based task creation, to-do lists, and progress tracking. We can extend this with custom workflows, reminders, or automation.

Can the system send and receive SMS messages?

Yes. We've built SMS integration directly into the chat interface so users can communicate with customers outside the platform without switching tools.

Can you build mobile apps for iOS and Android?

Yes. Nucleus includes native apps, and we can deliver the same level of functionality: chat, tasks, WebRTC calls, SIP, push notifications, and secure session handling.

How long does it take to build something like Nucleus?

A basic MVP can be developed in a few months. A full-scale system: with WebRTC, SIP, SMS, mobile apps, and on-prem deployment - takes longer. The timeline depends on your requirements and integration depth.

Nucleus – On-Premise Slack Alternative for Enterprise Chat & Calling

On-Prem Deployment

We developed Nucleus to run fully inside the client’s protected infrastructure. No data leaves the organization’s network, making it ideal for industries with strict security standards.

Video & Audio Calls, Powered by WebRTC and SIP

Nucleus supports high-quality WebRTC video and audio calls right in the browser. With SIP integration, users can place and receive cellular calls directly inside the platform, merging internal chats and external communication in one place.
The app is available on web, iOS, and Android, ensuring seamless access across devices.

Text Chat With Built-In Task Tracking

We developed a rich messaging system that handles:
• private and group chats
• threads
• SMS messaging (send and receive)
• file sharing
• message-based task creation
Users can turn any message into a task or to-do item and track it through completion – no need to switch apps.

Automation & System Integrations

Nucleus integrates with major CRMs and ERPs, letting teams automate calling workflows, customer support processes, scheduling flows, and sales operations. Combined with AI phone agents, it reduces manual workload and speeds up response times at scale.
