Do I need a load balancer for a low-traffic app?

Not always.

For a low-traffic app, you often do not need a load balancer unless you have a specific reason for one. A load balancer adds cost, complexity, and another thing to maintain, so it’s usually not worth it early on.

You probably don’t need one if:

• Your app runs on a single server/instance
• Traffic is light and predictable
• You’re okay with brief downtime during deployments or failures
• You don’t need automatic failover or horizontal scaling

You might want one if:

• You need high availability
• You plan to run multiple app instances
• You want zero-downtime deployments
• You need to scale out as traffic grows
• You want to terminate TLS/SSL centrally or do routing across services

Common low-traffic approach

For small apps, people often use:

• One VM/container
• A reverse proxy like Nginx/Caddy/Traefik
• A managed platform (e.g. Heroku, Render, Fly.io, Vercel, etc.) that handles balancing for you

Rule of thumb

If you only have one backend instance, a load balancer is usually unnecessary.
If you have two or more instances, or you need reliability and scaling, it starts to make sense.

If you want, I can help you decide based on your exact setup (hosting provider, number of instances, expected traffic, and whether downtime matters).
