Dify vs Langflow: Which AI App Builder Fits You in 2026?

Quick verdict: choose Dify if you want a productized platform where the knowledge base, model providers, agent runtime, and plugin marketplace are already wired together. Choose Langflow if your team lives in Python and wants a visual canvas where every node is an editable class you can open, fork, and rewrite. Both projects hover around 100K GitHub stars, but they answer different questions: Dify asks "which blocks do you need?", Langflow asks "which code do you want to touch?"

What each is built for

Dify, from LangGenius, is an integrated application platform. You configure datasets, prompts, workflows, and published apps (chatbots, agents, text generators) inside one managed surface. The trade-off is that the platform makes structural decisions for you, which speeds up standard builds and slows down unusual ones.

Langflow is a Python-native canvas. Every component on the graph is a Python class; double-click it and you are reading editable source. Developers use it to prototype retrieval and agent logic visually, then drop into code the moment a node needs custom behavior. It is a builder's tool first and a product second.

If you are also weighing Flowise, we covered how Langflow compares to it in our Langflow vs Flowise breakdown, and Dify against it in the full Dify review.

License and ownership

This section matters more than most teams realize at evaluation time.

  • Dify: a modified Apache 2.0 license. You cannot run multi-tenant SaaS on it without permission, and the logo must stay in the UI. Fine for internal tools and most commercial products; a real constraint for anyone reselling the platform itself.
  • Langflow: MIT, the most permissive common license. Commercial redistribution is unrestricted.

Ownership differs too. Langflow was acquired by DataStax in 2024, and DataStax was acquired by IBM (deal closed May 2025), so Langflow now lives inside IBM. Dify remains an independent company shipping its own roadmap.

Self-hosting weight

This is the biggest practical difference between the two. Dify's default Docker Compose stack runs roughly 15 containers (API, worker, web, Postgres, Redis, vector store, sandbox, plugin daemon, and more) and wants at least 2 cores and 4GB of RAM. You get a full platform, and you pay for it in operational surface: upgrades, volumes, and component failures.

Langflow installs with pip and runs as a single process; dual-core and 2GB of RAM is enough for evaluation. Something can still break, but there is one thing to restart, not fifteen. There is also a free Desktop app for local use.

RAG approach

Dify gives you a managed knowledge base: upload documents, choose chunking and retrieval settings, and attach the dataset to an app. Version 1.16.0 (July 2026) added the Knowledge Pipeline, which cleans and processes documents before indexing. You get usable RAG in minutes, with less control over the internals.

Langflow makes you assemble the pipeline: loaders, splitters, embeddings, vector store, and retriever are separate nodes you connect yourself. Setup takes longer, but you can inspect and replace every stage, which researchers and tinkerers tend to prefer.

Agents and MCP

Dify 1.16.0 introduced the Dify Agent (beta), a reasoning agent built into the platform, plus a plugin marketplace for extending tools and models. MCP support covers both client and server roles, over HTTP transport only.

Langflow shipped its ALTK and CUGA agent components back in 1.7 and reached v1.10.x by July 2026. Its MCP support also covers client and server, using Streamable HTTP. Because agent logic is just Python on the canvas, custom tool loops are easier to write but less standardized across projects.

Pricing

  • Dify Cloud: Sandbox free (200 message credits, 1 member, 5 apps), Professional $59/mo, Team $159/mo.
  • Langflow: no public paid tier. Free cloud plus a free Desktop app; serious deployments are self-hosted or negotiated through DataStax/IBM enterprise channels.

Dify's cloud gives small teams an obvious upgrade path. Langflow's model is either free or a sales conversation, with little in between.

Who should choose which

Pick Dify if you want one platform for chat apps, a managed knowledge base, and predictable cloud pricing, and you can accept its license terms and heavier deployment.

Pick Langflow if your team writes Python, needs MIT licensing for redistribution, wants a lightweight single-process install, or needs to customize retrieval and agent internals at the code level.

FAQ

Is Dify open source? Partially. The code is open under a modified Apache 2.0 license with conditions: no multi-tenant SaaS without permission, and the logo must remain.

Is Langflow really free? Yes. MIT-licensed, with a free cloud tier and a free Desktop app. Enterprise support is sold through DataStax/IBM.

Which one is lighter to self-host? Langflow, by a wide margin. One pip-installed process on 2 cores/2GB versus a roughly 15-container Docker stack that wants 2 cores/4GB.
