Langflow VPS hosting.

Yes. Langflow is open source, and a VPS is the most common way to run it permanently. On your own Langflow VPS the editor, your flows and their data stay on a server you control, reachable from any browser and running around the clock instead of on your laptop.

• Open-source Langflow, deployed from the marketplace
• Flows and data stay on your own server
• Root and SSH access for full control

Yes. Order your VPS, pick Langflow in the One-Click Apps marketplace and Coolify pulls the image, sets up persistent storage and starts the service for you. Then open Langflow in your browser using the address shown in your dashboard.

• Coolify handles the container setup
• Persistent storage for flows and settings
• Redeploy newer Langflow versions from Coolify

For building and testing a few flows, a smaller plan with moderate RAM is usually enough. RAG pipelines with a vector database, several parallel users or multi-agent flows need more RAM and CPU headroom, and running local models next to Langflow needs considerably more. You can switch to a larger plan as your flows grow.

• Testing and demos: entry-level plan
• RAG and team use: more RAM and CPU
• Local models: plan generous headroom
• Flexible terms, cancel anytime

Yes. Point your domain to the VPS and serve Langflow through a reverse proxy with a TLS certificate, so the editor and your API endpoints are only reachable via HTTPS. Require a login, keep API keys in global variables and use SSH keys to secure a public instance. Reverse proxy guide in the Help Center

• Own domain via DNS A record
• HTTPS through a reverse proxy
• Login required instead of auto-login
• SSH keys for server access

Yes. Every flow can be called through Langflow's API, so websites, bots or backend services send input and get the agent's answer back. Langflow can also expose flows as tools via the Model Context Protocol (MCP), letting MCP clients such as AI coding assistants or desktop chat apps use them directly.

• API endpoint for every flow
• Flows as tools for MCP clients
• Runs 24/7 on your own VPS

No. The one-click deployment handles the container setup, so you can start building flows right away. If you want more control, root access lets you work with Docker directly, add a PostgreSQL database or run extra services such as a vector store next to Langflow. Docker guide in the Help Center

• No Docker commands needed to start
• Full Docker access when you want it
• Add databases or tools alongside Langflow

A managed cloud workspace is convenient if you just want to try Langflow. A Langflow VPS gives you your own environment: you choose the model providers, keep data and API keys on your server, install custom components and run services like vector databases or Ollama right next to your flows.

• Your server, your data and credentials
• Custom components and extra services
• Resources sized to your workloads

You choose from our data center locations in Europe and America, so pick the one closest to your users or the APIs your flows call. Many North American teams start with Ashburn, Dallas or Los Angeles. Your flows, uploaded documents and credentials stay on your VPS, and only the providers you connect receive data.

• Locations in Europe and America to choose from
• Flows and documents stay on your VPS
• You decide which providers get data
