Agentic Index

Dify vs StackAI (2026)

Both build and deploy agents on enterprise data without code, at 9.5 and 11.5 of 14.

Dify is open source for building agents, chatbots and workflows, from 59 dollars a month with a free sandbox and free self hosting. StackAI is no code for workflows and agents on enterprise data, free to 500 runs monthly then enterprise custom per seat. StackAI documents more and leans harder into enterprise data connectivity; Dify is open source, which for some organizations settles it.

Choose Dify if

  • Open source with free self hosting is a requirement rather than a preference.
  • Chatbots alongside agents and workflows is the range you need.
  • A free sandbox lets you evaluate before any commitment.

Choose StackAI if

  • Documented coverage is broader and enterprise data connectivity is the hard part.
  • Enterprise per seat pricing is the model your procurement expects.
  • No self hosting burden is what your team can actually operate.
