Insomnia
- Git Sync on the free tier covers up to 3 users only
- Mock servers are capped at 1,000 requests a month on free, then $10 per 25,000
- Role-based access control requires Pro at $12 per user per month
- SSO, SCIM and vault integrations are Enterprise only at $45 per user per month
- Working without an account is limited to the local-only Scratch Pad
Vitest
- Assumes Vite: projects on webpack or other bundlers lose the main advantage
- Younger than Jest, so some plugins and matchers in the Jest ecosystem have no equivalent
- Jest compatibility is close but not exact, and unusual Jest configurations still need work to port
