'Free' self-hosting isn't free — you own the servers, updates and reliability, and model usage bills separately once the included message credits run out. Throughout this review we weigh it against LangChain.
✓ Pricing re-verified 21 Aug 2026
Source-available and free of a software fee to self-host — the Community Edition ships under the Dify Open Source License, a modified Apache 2.0 with additional conditions — while the managed Dify Cloud adds a free Sandbox, Professional at $59/mo ($590/yr) and Team at $159/mo ($1,590/yr), each priced per workspace (2026). Self-hosting still costs you infrastructure, model usage and any commercial licence those terms require. Cloud plans include message credits for supported model providers; once those run out you connect your own provider API key and pay that provider directly.
Judge it on evidence rather than adjectives. Look for a published security page, single sign-on and role controls on the plan you would actually buy (they are often gated to higher tiers), a status page with real incident history, and a clear answer on where your data is stored. If the tool will hold anything sensitive, those four answers matter more than any feature comparison.
This is a researched assessment, not a hands-on test — where we've used a tool ourselves, we say so explicitly. We name what each tool is good and bad at, and we have no affiliate relationship with Dify — we earn nothing whether you sign up or not.
