Where the server lives

Langflow in Rio de Janeiro

With Rio de Janeiro selected, your VPS with Langflow runs in Mega's original data center, on our own network with a presence at the Rio internet exchange (IX.br) and redundant transit. It is the lowest latency for users in Rio, Espírito Santo and Minas Gerais, and our support team works in the same city as the server.

What is Langflow

Langflow is an open-source project for building AI applications on a drag-and-drop canvas. Each block represents a piece of the flow, such as chat input, language model, prompt, tool, text splitter or vector store.

By connecting these blocks you can create an agent that uses tools, a chatbot that queries your own documents (RAG) or a sequence of AI steps. You can test everything in the playground while you build, and every published flow gets an API endpoint that your website, app or automation can call.

The answering capacity comes from the AI provider you connect to Langflow, such as OpenAI. In the Mega installation, login is mandatory, login attempts are limited to 5 per minute and any new sign-up stays pending until the administrator approves it.

What to use Langflow for on your server

Support based on your files

A RAG flow that answers questions from manuals, internal policies or product catalogs.

Agents that use tools

The agent searches the web, queries an API or runs a calculation before giving its answer.

AI as a service for your system

Your store, app or automation sends a request to the flow endpoint and receives the result.

Idea testing

Validate an AI concept in the playground before spending time coding.

Vector store with Qdrant

Install Qdrant on the same VPS and use it to store embeddings, if memory allows.

Flows as tools via MCP

Publish your projects as an MCP server so other agents can use them.

What comes already configured

Mandatory login

No one opens the editor without authenticating. The administrator is already created at delivery.

Sign-ups with approval

Anyone who requests an account waits until you approve it.

Login attempt limit

Up to 5 login attempts per minute are accepted, which hinders brute-force attacks.

Automatic HTTPS

Your own address already responds with a Let's Encrypt certificate.

The Docker container starts on its own when the server reboots.

Pinned version

The installation uses Langflow 1.12.6 and only changes when you decide to update.

Which plan to choose for Langflow

Idle Langflow uses about 1.2 GB and fits from 1536 MB of free memory, so Basic is the recommended plan to start. Move up to Plus, Pro or Turbo if you will work with large documents or several simultaneous users.

Plan	Best for
Basic 2 vCore · 2 GB	Recommended plan: handles Langflow with one person building agents and flows, tests and light API calls.
Plus 2 vCore · 4 GB	For chatbots in production with more memory headroom, larger flows and a few simultaneous users.
Pro 4 vCore · 6 GB	For RAG flows with large documents and small teams editing and calling the API at the same time.
Turbo 4 vCore · 12 GB	For heavy use: many simultaneous users, several heavy RAG flows and the most memory headroom in the lineup.

Frequently asked questions

Frequently asked questions about Langflow hosting

How much does a VPS with Langflow cost?

Monthly prices are for Start, US$ 11.95 for Basic, US$ 16.95 for Plus and US$ 21.95 for Pro. AI usage is billed separately by the provider you connect, such as OpenAI.

What is the minimum plan for Langflow hosting?

Langflow needs 1536 MB of free memory, so Start, with 1 GB, falls short. Basic, with 2 GB, is the recommended plan to start.

Do I need an AI API key for self-hosted Langflow?

Yes. Langflow builds and runs the flow, but the answers come from the model of the provider you choose. The key can be stored in global variables or set directly in the model component.

Can anyone create an account on my Langflow?

They can request one, but they cannot get in. Every new sign-up stays pending until the administrator approves it, and login allows at most 5 attempts per minute.

Can I run Langflow with Qdrant on the same VPS?

Yes. Langflow has its own Qdrant component, and both can run on the same VPS, each on its own address, as long as there is free memory. The Plus plan was designed for this combination.

Who updates Langflow after installation?

You decide. The delivered version is 1.12.6 and it does not change on its own, so nothing breaks by surprise. When you want to update, do it over SSH with root access, preferably after testing.

How do I reinstall the server if I want to start over?

Use the reinstall option in the VPS panel, in the client area. It rebuilds the system, and you can also change the password and open the console from the same panel.

Is there 24/7 support and a lock-in contract?

Support is available 24 hours a day, every day, by WhatsApp, ticket and phone, for everything involving the server. Using Langflow itself follows the project's documentation. There is no lock-in, and you have 7 days to request a refund.
