Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buffer

  • The free plan allows 3 connected channels and 10 scheduled posts per channel
  • Essentials at $5 a month covers a single user; team members need the Team plan at $10 a month
  • Approval workflows and custom permissions are Team tier only
  • API access is rationed by plan, from 3,000 monthly requests on free to 15,000 on Team
  • Content ideas are capped at 100 on the free plan

Formstack

  • More expensive than form builders that only collect, which is the fair comparison for simple use
  • Document generation and signature sit in higher tiers, so the headline price is not the working price
  • The interface has accumulated features over a long life and shows it
  • Overkill where a form only needs to collect an answer
