Building an Open Source Privacy Messenger with AI as a Solo Founder

A while ago, I decided to answer a simple question: Could a single developer build a modern messaging platform with the help of AI? The answer turned out to be yes. MeetVap is the result of that experiment. I built it as a solo founder, but I definitely wasn't coding alone. AI became part of my daily workflow. ChatGPT helped me think through architecture, review design decisions, explain unfamiliar technologies, and solve countless small problems. When OpenAI released Codex (GPT-5.5), it became another huge productivity boost, helping implement features, refactor code, and speed up development. Instead of spending hours searching through Stack Overflow or documentation, I could focus on building. That doesn't mean AI built the project for me. Every architectural decision, feature, and integration still required engineering work, debugging, testing, and many iterations. But AI removed a huge amount of friction from the development process. The project itself is a privacy-first messenger with a different philosophy from most existing platforms. Some of the things I wanted from day one were: No phone number or email required local-first message storage instead of permanent server storage PANIC PIN function Voice and video calls Real-time voice changer for outgoing and incoming calls Mini Apps Enterprise and self-hosted deployments Building a messenger is much more complicated than it looks. Every feature touches networking, synchronization, mobile platforms, backend services, notifications, databases, encryption, and user experience. As a solo developer, I ended up working on everything: backend APIs, React Native, infrastructure, deployment, App Store releases, CI/CD, and server administration. Recently I made the project open source. Privacy software should be transparent. If people are expected to trust a messenger, they should be able to inspect the code, report issues, and contribute improvements. I also think this project is an interesting example of how modern AI tools are changing software development. They're not replacing engineers—they're dramatically increasing what a single engineer can accomplish. I'm excited to see where both the project and AI-assisted development go next. If you're interested in messaging systems, React Native, distributed systems, or building ambitious projects as a solo founder, I'd love to hear your feedback. Thanks for reading!
