VPN service with billing and config automation
Telegram bot, subscriptions, WireGuard/OpenVPN, and automatic access revocation — no manual provisioning.
About the Project
Centralized VPN access management on Go. Full subscription lifecycle: payment in a Telegram bot, WireGuard/OpenVPN config generation, recurring charges, and expiry handling. Background workers and idempotent jobs activate and revoke access without an operator.
Solution Architecture
Backend Services (Go)
Set of microservices for managing users, tariffs, servers, and locations. Implements gRPC API.
Subscriptions & background jobs
Activation, renewals, access revocation, and config sync across nodes via queues and idempotent workers.
Telegram Bot Interface
Main entry point for users. Allows purchasing subscriptions, receiving configs, and managing settings.
Key Features
Reliable activation
A paid subscription is driven to config delivery with retries — a partial outage does not drop the payment.
Scalability
Easy addition of new VPN servers in different locations without service interruption.
Full Automation
Key generation, instruction sending, and access control without operator involvement.
3,000+ active tunnels
Zero-touch configuration
Uptime: 99.9%
