Kubernetes for Solo Developers: When It's Worth It (and When It's Not)

Kubernetes is massively over-engineered for most solo projects. Here's an honest breakdown.

Skip Kubernetes If:

• Your app handles under 1,000 requests/day
• You have one or two services
• Your team is 1-3 people
• You don't have a dedicated DevOps engineer

A single VPS with Docker Compose is dramatically simpler and nearly as reliable.

Use Kubernetes When:

• You have 5+ microservices with different scaling needs
• You need zero-downtime rolling deploys
• Traffic is genuinely spiky (10x swings)
• Someone on your team already knows it

The Better Alternative: Railway or Render

For solo developers, these platforms give you 80% of Kubernetes' value at 10% of the complexity:

• Automatic deploys from GitHub
• Private networking between services
• Auto-scaling based on CPU/memory
• Zero-downtime deploys
• No YAML required

If You Do Use Kubernetes: Essentials

# Health checks are non-negotiable
livenessProbe:
  httpGet:
    path: /health
    port: 3000
readinessProbe:
  httpGet:
    path: /ready
    port: 3000
# Resource limits — always set them
resources:
  limits:
    memory: '512Mi'
    cpu: '500m'

The Honest Recommendation

1. Start with Railway or Render
2. Move to ECS or Cloud Run when you need more control
3. Only adopt Kubernetes if you're hiring someone to own it

The time you'd spend learning Kubernetes is better spent shipping features. The AI SaaS Starter Kit ships with a Docker-based setup that runs on Railway, Render, or Fly.io — no Kubernetes required.
