Possible disadvantages of Substack

  Besides Substack's fee, payment processors like Stripe also take a percentage, further reducing net earnings for writers.

• Complex Configuration
  Configuring and tuning chains for specific tasks can become complex, especially for newcomers who need to understand each component’s role and interaction.
