A good rule of thumb is: start free where switching costs are low, pay early where switching costs are high.
Start with free plans or low-cost tiers for:
- Writing and note-taking tools
- Scheduling and link-in-bio tools
- Basic design or thumbnail tools
Consider paying early for:
- Email and audience data (migrations here are painful).
- Domains and hosting (your URL structure lasts a long time).
- Payment processing that you trust.
The real question is not “free or paid,” but “what will be expensive to change later if I’m right about this direction?” Invest there. Everywhere else, start scrappy and upgrade only once usage and revenue justify it.
