Gotchas
- mediumForms, Documents, and Sign are separate products — needing all three stacks subscription costs fast.¹
- medium'Start free today' reads like a trial, not a lasting free tier — confirm before building workflows.¹
- mediumGuess: forms hosted on subdomains may create migration lock-in; verify data export options first.¹
- lowSign starts at $59/month, higher than some rivals; unlimited users soften the blow.⁶
