Flowise vs Dify

Two open-source projects, both visual, both compared by teams shopping for a low-code LLM platform. Flowise is a Node.js-rooted visual LLM canvas built on LangChain.js; its maintainers announced that official maintenance ends in August 2026. Dify is a full self-hostable AI product platform: the canvas is one feature alongside a chat UI, knowledge base, team workspace, model gateway, and embed widget. They overlap on "drag blocks to build a flow" but live in different product categories. Picking the wrong one is expensive: shipping an end-user-facing AI product on raw Flowise is weeks of UI work; embedding a single flow inside a JS service via Dify means adopting a whole platform layer you do not need.

Flowise

Node.js-rooted visual LLM canvas built on LangChain.js. Existing users need a maintained fork or migration plan after the announced end of official maintenance.

Dify

Self-hostable AI product platform. Workflow canvas, RAG pipeline, model gateway, chat UI, and a team workspace shipped together -- batteries-included for AI apps.

The short answer

  • Existing JS deployment boundary: Flowise fits Node.js stacks, but continued use needs a maintained fork or migration plan.
  • Winner for "ship a standalone AI product": Dify. Full surface ships by default.
  • New deployment boundary: Dify has an active maintained product surface; do not select Flowise without an ownership plan.
  • Winner for non-engineer product iteration: Dify.
  • Best for: Flowise as a canvas inside a JS service; Dify as the whole AI product.

Two different mental models

The right tool depends on which of these reads like your problem.

Flowise thinks "visual canvas for LLM flows in the Node ecosystem". You drag blocks for prompts, retrievers, models, and tools, wire them together, and either embed the flow in a JS product or expose it via API. The canvas is the primary product; the embed widget is the simplest way to ship.

Dify thinks "AI product platform". You log into a self-hosted dashboard, drag blocks onto a canvas, attach documents to a knowledge base, pick a model, and publish a chat app. The platform is the product.

If your problem is "drop a chatbot into our Next.js app this week", that is Flowise shaped. If your problem is "ship an internal product the support team uses every day", that is Dify shaped.

Use cases -- when each one wins

Flowise fits when

  • Next.js / Remix / SvelteKit products. JS-shaped apps adding an LLM step.
  • Web-team owned AI. Frontend engineers who do not want Python services.
  • Quick chat embeds. The embed widget is genuinely clean.
  • Smaller, curated component set. Less to learn for non-LangChain veterans.
  • Lighter self-host footprint. A single Node service plus your store.

Dify fits when

  • Internal RAG chatbots. Upload PDFs and policies, get a working Q&A bot.
  • Customer-facing chat apps with full surface. Not just a widget, a managed app.
  • Non-engineer prompt iteration. Product or ops staff edit prompts and flows.
  • Model gateway needs across many apps. One place for keys and usage.
  • AI prototypes that should look like products. Time-to-demo matters.

Learning curve

Flowise is friendlier for JS engineers. The runtime is Node, the engine is LangChain.js, the embed is a JS snippet. Most web devs ship a working chat widget in an afternoon.

Dify is friendlier as an end-to-end product. A non-engineer can ship a working internal bot in an afternoon: log in, drag blocks, attach a knowledge base, publish. The cost is adopting the platform layer even when you only wanted a single flow.

Practical rule: if the artifact is "a flow we drop into a JS app", Flowise wins. If the artifact is "an AI product the team uses every day", Dify wins.

Pricing comparison

Both projects publish self-hostable source. Flowise announced that official maintenance ends in August 2026; evaluate a maintained fork or migration path before adopting it for new production work.

Workload costDepends on calls, context, retrieval, hosting, and maintenanceDepends on calls, context, retrieval, hosting, and plan
Hidden costsBuild product surface around itSelf-host ops (DB, vector, upgrades)

The pattern: compare model calls, retrieval, hosting, and platform usage. Dify packages a wider application surface; Flowise requires an explicit plan for ongoing maintenance or migration after the announced end of official maintenance.

Final verdict

These two overlap on the canvas layer but live in different categories. The right call comes down to two questions: do you need a flow inside a JS product, or a standalone AI product?

  1. Dropping a flow into a JS app: Flowise wins. Native Node fit, clean embed widget, lighter ops.
  2. Shipping an end-to-end AI product for the team: Dify wins. Knowledge base, workspace, and full product surface ship by default.
  3. Greenfield prototype: Dify gets you to a product faster; Flowise gives you more flexibility once you decide to ship into your own surface.

Meta-recommendation: a lot of teams pick a canvas tool because it "looks like a platform" and then spend months building the surface around it -- Dify ships that surface by default. Plenty of teams adopt Dify when all they actually wanted was a flow they could call from one JS service, and the platform layer becomes ops debt. The wider landscape is in the AI Agent Frameworks pillar; the deeper shortlists are best Flowise alternatives and best Dify alternatives.

FAQ

Flowise vs Dify -- which one should I pick?
Dify is the safer default for a new maintained deployment. Flowise remains relevant to existing Node.js deployments and forks, but its maintainers announced that official maintenance ends in August 2026. Flowise is a canvas; Dify is a broader product platform.
Is Flowise a product platform like Dify?
Not exactly. Flowise has a clean chat embed and an API for flows, but the product layer is narrower than Dify. Dify ships workspace, knowledge base, multi-app management, and a model gateway in the same dashboard. Flowise is sharper as "a flow inside a JS product".
Is Dify easier to learn than Flowise?
For end-to-end product iteration -- yes. Dify is a dashboard for the whole AI product. For embedding a flow inside a Next.js or Node backend, Flowise is lighter and feels more native to JS engineers.
How do token costs compare?
Both can call the same models, but total cost depends on call count, context, retrieval, hosting, and platform usage. Flowise also announced an August 2026 end of official maintenance, so fork ownership or migration belongs in the cost model.
Can Flowise replace Dify in production?
Technically it can serve embedded flows, but a new production adoption now requires a maintained fork or an explicit migration plan because official Flowise maintenance is ending. Dify also packages a broader product surface.
Are Flowise and Dify open source?
Yes -- both. Flowise is Apache 2.0 with a separate hosted offering. Dify is open source under a custom licence: free to self-host for most use cases, with restrictions on reselling it as multi-tenant SaaS.
Which one wins for RAG workloads?
Dify -- end-to-end. Document upload, chunking, retrieval, chat UI, and a knowledge base UI are day-one features. Flowise has RAG components on the canvas but expects you to build the product around them.
Can I use Flowise and Dify together?
Uncommon -- they overlap on the canvas layer. Most teams pick one. The cleaner composition is Flowise as the flow engine inside a JS product, or Dify as the full AI product platform with no Flowise.
