LangFlow hosting
LangFlow is a visual LangChain IDE — build LLM workflows with drag-and-drop nodes and deploy them directly as an API.
Excl. VAT. Monthly cancellable.
- Own container + persistent data
- Optional GPU acceleration
- No data to third parties — everything stays in NL
Available immediately. No long-term contracts.
LangFlow is an open-source visual tool for building LangChain applications. Like Flowise, you drag nodes for LLMs, prompts and chains together — but LangFlow is built by the LangChain team itself and stays closest to the upstream API. For those who also want to work with code: LangFlow flows are exportable as Python code.
At Virtual Computing you get LangFlow on your own subdomain, with a dedicated container and automatic updates. Your documents and flows stay in the Netherlands; we optionally attach a Postgres database for flow persistence and a Qdrant vector store for RAG.
LangFlow is a strong choice for teams who use LangChain seriously and want the visual flow as a prototyping tool before they put the generated Python into production.
LangFlow is ideal for
Quickly validate LLM app prototypes
Build a working RAG app in an hour. Demo to stakeholders, iterate fast on prompts and chains.
Python export for production
A validated flow can be exported as Python code and deployed in your own CI/CD pipeline.
Multi-agent systems
LangFlow supports agents and tool use — build a planner + executor + retrieval agent that work together.
Education and internal training
Let colleagues experience LangChain without a Python course. Drag-and-drop nodes make concepts like embeddings and chains tangible.
Included in every deployment
Official LangChain team
Maintained by the team that builds LangChain itself — always up to date with the newest features.
Python export
Every flow is exportable as plain Python — no lock-in.
Live preview
Test your flow directly in the UI while building. See every intermediate step from LLM call to retrieval.
Multi-LLM + vector store
OpenAI, Anthropic, Hugging Face, Cohere — plus Chroma, Pinecone, Qdrant out-of-the-box.
Custom nodes
Add your own Python nodes for business logic that LangChain doesn't ship by default.
API endpoints per flow
Each published flow gets a REST endpoint with API-key auth — callable straight from your app.
