Short answer: they solve different problems, and many teams will use both. Dify is a superb horizontal builder for agents and workflows. Kernos exists for the moment an agent must safely write into a system of record. Here is the full comparison — including where Dify wins.
| Dimension | Dify | Kernos |
|---|---|---|
| Core question | "How fast can teams build agents and workflows?" | "How can agents act on systems of record, safely?" |
| Modeling | Workflows and prompt graphs | Typed business ontology — objects, links, actions, bi-temporal |
| Write-side governance | Logs and moderation tooling | Staged proposals → multi-node approval DAG (segregation of duties) → executed |
| Audit | Run logs | Append-only bi-temporal trail, causal-ID replay |
| ERP depth | Generic API/HTTP nodes | SAP-native: OData, IDoc, BAPI, events, CDC + three-way reconciliation |
| Self-hosting | Community edition (docker compose) | One-command full-stack bootstrap, air-gapped capable |
| Ecosystem | Very large community, template marketplace, broad model support | Early access — 18 modules, 253 OpenAPI endpoints, six release bands |

Pretending otherwise would waste your time. Dify has one of the largest open-source communities in the space, a mature visual builder, broad model support, and a template ecosystem that gets a working prototype done in an afternoon. For internal tools, chat experiences, and RAG applications where mistakes are cheap, it is a rational choice.
The divergence is one word: authority. Dify's agents inform people. The question of when an agent's output is allowed to change a production system — who approved it, under which policy, with what evidence, and how you reverse it — lives outside its scope. That is not a flaw; horizontal breadth and vertical depth are different products.
Kernos takes the opposite bet. The platform models your business as a typed ontology, wraps every write-side action in a three-frame loop (propose → approve → audit, with segregation of duties enforced in code), and treats SAP as the authoritative source: nothing is claimed complete until SAP's own event confirms it. Reads are cheap. Writes are governed.
Fairness cuts both ways: Kernos's visual flow builder and template marketplace are earlier in maturity than Dify's. If your primary need is a chat surface over documents with no system-of-record writes, Kernos is heavier than you need today. Managed multi-tenant SaaS is also still on the roadmap — self-hosted and private-cloud deployments are what ship now.
