VPN Sales Bot
A platform for selling V2Ray subscriptions through Telegram, with a customer bot, an admin bot and a full Persian web dashboard. I built it for myself in about six weeks, and the code is open source.
All business logic lives in one shared service layer in the FastAPI backend, so the bots, the REST API and the background workers use a single source of truth. Data is stored in PostgreSQL through async SQLAlchemy with Alembic migrations, and Celery on Redis handles background work such as talking to the VPN panels (Marzban, X-UI) and payment gateways.
The customer and admin bots are written with aiogram 3, and the web dashboard is Next.js, TypeScript and Tailwind. The whole stack runs on Docker Compose, and a one-command installer sets up everything on an Ubuntu server: Docker, configuration, migrations, Nginx with free SSL, nightly backups and the first admin user.
