Why most SaaS MVPs should stay a monolith

Why most SaaS MVPs should stay a monolith

Microservices are an organisational tool, not a shortcut for solo founders. Most MVPs fail on distribution, not on modular deployment.

Stay monolithic until you have clear scaling pain, separate teams or compliance zones that force a split.

Costs of splitting early

  • Distributed tracing and logging across services.
  • Contract testing between APIs.
  • Slower local development.
  • Harder onboarding for the client's future team.

Modular monolith pattern

Keep one deployable unit but enforce module folders: billing, core domain, notifications. Extract a service when a module needs independent scaling or release cadence.

Use this as a working checklist inside your team first. When the same steps repeat every week and spreadsheets start breaking, that is usually the moment to scope a decision map covering product value, frequency, integration needs and ownership risk as an owned system.
