Decision summary
Choose Dify when
self-hosting and source-level customization are requirements, a low-code LLM application canvas is the primary authoring experience, and the platform team is prepared to operate the supporting services.
Choose GraphN when
the team wants a managed workflow and inference platform, one visual and YAML definition, built-in isolation for custom functions, workspace resources, and open-weight or custom model serving.
Dify is an open-source LLM application platform with visual workflows, agent apps, knowledge, model-provider plugins, APIs, cloud hosting, and self-deployment. GraphN is a managed production-agent platform that connects visual/YAML workflows to workspace resources, isolated functions, and managed open-weight or custom model infrastructure.
Dify and GraphN both let a team build an agentic application without starting from a blank web server. Both provide visual workflows, model selection, tools, retrieval, secrets, logs, and API deployment. That makes Dify one of the most direct comparisons in this series.
The largest difference is not the canvas. It is operational ownership. Dify Community Edition can run wherever Docker runs, which gives a team source access and deployment control. GraphN provides workflow authoring and execution, managed functions, knowledge, and models as one product.
Note: This is a source-based architecture guide, not a benchmark. Dify's new Agent runtime was documented as beta, and capabilities differ across Community, Cloud, and Enterprise editions.

Visual workflows are not the same workflow model
Dify's workflow builder is designed around LLM application nodes: user input, LLM, agent, knowledge retrieval, code, templates, conditions, iteration, tools, and outputs. It is approachable for teams building chat and generative applications and can publish an app behind an API.
GraphN's workflow DSL is the underlying definition for both its canvas and code-based tooling. It references separately managed agents, functions, MCP servers, secrets, models, knowledge bases, and storage. The CLI can validate, dry-run, update, and publish the same resource graph.
That creates a different source-of-truth decision:
- Dify's canonical application is primarily the platform's app/workflow configuration, with DSL export and service APIs around it.
- GraphN explicitly exposes YAML as an authoring surface equal to the canvas and connects it to repository-oriented CLI workflows.
If Git-based review is mandatory, prototype the full export, diff, environment promotion, secret binding, and rollback path in either product. A visual editor being able to export JSON or YAML does not automatically make Git the deployment authority.
Agent execution: classic node and new runtime
Dify's classic Agent node gives an LLM iterative control over selected tools. It is suitable when the model should decide which tool to call and when. Dify's newer Agent can be built once and run as a standalone app or inside a workflow. It adds a filesystem and sandbox capable of commands and package installation.
The distinction matters because the new runtime was documented as beta at review time. Dify's Agent documentation also includes a direct security notice: Community Edition file-access controls reduce cross-conversation risk, but the Agent runtime is not intended as a hardened boundary between mutually untrusted users or workloads.
GraphN agents reason and call approved tools, while custom code lives in functions or MCP services. GraphN does not give every agent a general writable command environment. That is less open-ended, but it keeps agent reasoning and deterministic code as separate product capabilities.
Choose based on the workload:
- A coding or research agent that must install packages and manipulate a session filesystem may fit Dify's new Agent shape.
- A governed business workflow that needs small deterministic transformations or API calls may fit GraphN functions.
- Mutually untrusted general-purpose code requires a dedicated security review in either product, not a label-based assumption.
Code-node isolation is a separate comparison
Dify's Code node executes Python or JavaScript in a separate sandbox container. Documentation says it blocks filesystem access, system commands, and direct network requests; permitted outbound access routes through an SSRF proxy and can be disabled. Dependencies are preinstalled rather than installed per node.
GraphN functions use a managed isolated environment and an SDK for model calls, storage, knowledge, and other platform services.
These products expose different code-execution contracts:
Scroll horizontally to compare
| Question | Dify Code node | GraphN function |
|---|---|---|
| Environment | Separate sandbox container service | Managed isolated function environment |
| Languages | Python and JavaScript | Python |
| Filesystem/system commands | Restricted by sandbox | Bounded function runtime |
| Network | SSRF-proxied or disabled by configuration | Platform/runtime policy plus SDK services |
| Dependencies | Preinstalled allowlist | Function package/runtime constraints |
| Platform access | Workflow variables and node outputs | Typed async GraphN SDK |
An isolation label alone does not prove either product is secure enough for a particular threat model. Validate documented guarantees, egress, package supply chain, secret exposure, timeout enforcement, and cleanup behavior.
Workflow state and reliability
Dify stores application definitions, runs, messages, and workflow state in its platform databases and queues. Nodes support retry and error-handling paths. Self-hosters operate the API, workers, PostgreSQL, Redis, and related services that make this reliable.
GraphN records published workflow versions and executions and offers synchronous and asynchronous run modes. Its workflow definition supports bounded retries through explicit patterns and error visibility through traces.
Neither public feature list replaces a failure test. Use a side-effecting tool and interrupt:
- before the tool call;
- after the remote system commits;
- before the workflow records the result;
- during a retry;
- during cancellation.
The outcome reveals whether at-least-once execution can duplicate work and where idempotency belongs.
Knowledge and retrieval
Dify's Knowledge Retrieval node searches one or more knowledge bases and passes results to later nodes. Dataset-level and node-level retrieval settings can filter and rerank results. Dify supports multiple vector-store backends in self-hosted configurations.
GraphN knowledge bases are workspace resources with text or multimodal embedding options, URL/file ingestion paths, ranked retrieval, and optional reranking. Storage is a separate workspace resource for original files and generated artifacts.
Dify is attractive when a team wants to select and operate its vector database as part of a broader open-source stack. GraphN is attractive when retrieval infrastructure should be a managed service and multimodal indexing should use models from the same platform.
For both, verify:
- document-level authorization at query time;
- deletion propagation through chunks, vectors, caches, and backups;
- embedding-model migration;
- citations and source metadata;
- tenant isolation in shared indexes;
- behavior when retrieval returns no evidence.
Deployment and the self-hosting bill of materials
Dify's deployment overview supports Docker wherever it runs. The standard Docker Compose deployment starts core API, websocket, worker, scheduler, web, plugin, and agent services plus PostgreSQL, Redis, Weaviate, Nginx, SSRF proxies, and sandbox services. Enterprise adds a Kubernetes high-availability path, SSO, and multi-workspace management.
This is a real advantage for data residency, source customization, offline environments, and teams that require infrastructure ownership. It is also an operational commitment:
- database backup and migrations;
- queue and worker scaling;
- object and vector storage;
- ingress and TLS;
- sandbox and proxy hardening;
- image and plugin supply chain;
- observability and upgrades.
GraphN does not expose that application stack for customer operation in the normal managed path. Teams publish resources and consume the platform. That reduces platform work but shifts questions toward vendor topology, region, networking, retention, and service controls.
Self-hosting is not automatically more private, and managed hosting is not automatically more secure. The deciding factor is whether the chosen operator can implement and evidence the controls.
Models and inference
Dify supports model providers through plugins and credentials. It can connect to commercial APIs and self-hosted inference endpoints. The team remains responsible for those model services, quotas, and provider contracts.
GraphN also connects external OpenAI-compatible endpoints, but it can host built-in open-weight models and import custom weights from Hugging Face or S3. Agents select models as workspace resources, and the platform also provides embedding, reranking, vision, and text-to-speech services for relevant workflows.
Use Dify when the model plane is already solved or should remain independently replaceable. Use GraphN when GPU serving and custom model lifecycle are part of the same platform problem as agent execution.
Observability
Dify's Logs view captures application runs, node status, model calls, tool activity, and agent reasoning details. Self-hosted teams can also integrate external tracing and monitoring, but they own collection and retention.
GraphN exposes workflow executions, per-node traces, token and timing information where available, logs, and usage views tied to workspace resources.
Evaluate more than the happy-path UI:
- Can operators search by external request and user IDs?
- Can telemetry leave the product through standard exporters?
- Are prompts, retrieved text, tool arguments, and files independently redacted?
- Can a trace identify the exact app/workflow and resource versions?
- Are queue, database, sandbox, and model failures distinguishable?
Dify self-hosting provides infrastructure-level access. GraphN provides tighter platform-level correlation. Each can be an advantage for a different operations team.
Authentication, secrets, and plugins
Dify Community self-hosting requires careful environment configuration. Its
SECRET_KEY protects sessions, JWTs, file signatures, and encrypted OAuth credentials and must be replaced before production. Changing it later invalidates sessions and can make existing encrypted OAuth credentials unrecoverable. Enterprise adds SSO and multi-workspace controls.GraphN uses workspace membership and workspace-scoped API keys. Secrets are managed as resources and referenced by agents, MCP servers, imported models, and integrations.
Plugin and tool credentials deserve separate review in both systems. Determine whether an editor can reveal values, whether a runtime receives all environment variables or only selected bindings, and how credentials are rotated without republishing the application.
Migration boundaries
Dify to GraphN
- Export and inventory apps, workflows, model providers, tools, datasets, variables, and secrets.
- Map supported nodes to GraphN step types; move Code-node logic to functions.
- Expose plugins or external actions as MCP servers or services.
- Re-ingest source documents into GraphN knowledge bases rather than copying vector-store internals.
- Register models and secret references as workspace resources.
- Rebuild API/session behavior and replay production-shaped traces.
GraphN to Dify
- Export workflow YAML and linked resource definitions.
- Recreate the graph in Workflow or Chatflow and define application inputs/outputs.
- Port functions to Code nodes only if their language, package, network, and isolation requirements fit; otherwise keep them as external tools.
- Configure model-provider plugins, datasets, file storage, and credentials.
- Choose Cloud, Compose, or Enterprise Kubernetes and design backups, scaling, and upgrades.
- Validate API contracts, async behavior, and tenant authorization.
Choose Dify when
- Open-source self-hosting and source modification are hard requirements.
- A low-code LLM application builder is the primary product experience.
- Your team wants to select databases, vector stores, storage, and model providers.
- Dify's app, Chatflow, plugin, and agent ecosystem matches existing workflows.
- A platform team can own the full service and sandbox topology.
Choose GraphN when
- Managed agent execution and managed GPU/model serving should come from one platform.
- Canvas and YAML must be equal authoring surfaces.
- Workspace resources need a shared publish, API, and access lifecycle.
- Custom Python functions need managed isolated execution and a platform SDK.
- Multimodal knowledge, object storage, MCP tools, and custom weights should be integrated rather than assembled.
Run an operational proof of concept
Build one document-processing application in both systems. It should use a private file, multimodal retrieval, an autonomous tool decision, deterministic code, a secret-backed API, parallel steps, and a structured output.
Then:
- restore from backup;
- upgrade one minor version;
- rotate every credential;
- disable network egress from code;
- delete a source document;
- induce a worker and vector-store outage;
- inspect the resulting trace as a support engineer.
The exercise turns “open source versus managed” into concrete staffing, security, and recovery evidence.
