WebTrit is open-source and production-ready, built for developers and telecom teams who need more flexibility than closed, vendor-controlled solutions allow.

You get full source access and control: customize the UI, control the call logic, and integrate with any backend. Your infrastructure, your rules.

• Developers who need deep customization
• Telecom operators tired of vendor lock-in
• Teams replacing limited or overpriced tools

Communication tools should be open, flexible, and yours to shape.
