Hey everyone, My team recently spent months building an end-to-end AI Voice Agent platform. It started as a custom build for an enterprise client who needed a system that could handle real business conversations, follow visual workflows, and extract structured data post-call. Right as we crossed the finish line, the client’s internal priorities shifted, and the project was shelved. Instead of letting a production-ready codebase gather dust, we’ve decided to offer a commercial yearly license ($3,000/year) to founders or agencies who want to skip the 4-6 month build phase and go straight to market. Here is exactly what’s under the hood: Visual Workflow Builder: Built with React Flow. It’s a drag-and-drop canvas with Start, Agent, Tool, and End-call nodes, plus conditional branching. The Pipeline: Real-time STT ➔ LLM ➔ TTS architecture. Telephony: Out-of-the-box integrations for Twilio, Vonage, Telnyx, and Plivo (inbound, outbound, and human handoff routing). Tool Calling & Extraction: Agents can trigger custom business logic mid-call and extract structured JSON data when the call ends. The Stack: Next.js 15, React 19, Tailwind CSS on the frontend. Python, FastAPI, SQLAlchemy, PostgreSQL on the backend. Containerized with Docker. Why a licensing model? We don't want to run an AI Voice SaaS ourselves right now - our focus is on our core development business. The $3k/year license gives you full access to the source code, permission to white-label it, and the ability to sell it to your own clients (local businesses, real estate, clinics, etc.) or launch it as your own SaaS. You get the platform, deployment documentation, and our handover support to get it spun up on your infrastructure. If you’ve been looking to capitalize on the AI voice trend but didn't want to build the complex real-time telephony architecture from scratch, this is basically a cheat code. Drop a comment or shoot me a DM if you want to see a live demo, look at the UI, or discuss the tech stack! Happy to answer any architecture questions in the comments as well.   submitted by   /u/No-Consequence-7191 [link]   [comments]
