Multi-tenant SaaS for $30/mo: wildcard SSL + nginx vhost generator + Flask routing
A new multi-tenant SaaS architecture allows for 50+ tenants on a single $30/month VPS. The setup utilizes wildcard SSL, nginx, and Flask for efficient routing and provisioning. This approach is designed for solo founders, avoiding the complexity of microservices until scaling is necessary.
- ▪The architecture supports 50+ tenants on subdomains using a single VPS.
- ▪It employs wildcard SSL and nginx for routing without needing new configurations for each partner.
- ▪The initial setup can be completed in about 8 hours, with a total infrastructure budget under $5,000 for 12 months.
