Langflow is a visual AI flow builder from the creators of LangChain - on the canvas, you drag nodes (an LLM model, prompt, tool, vector database), connect them into a graph without writing code, and expose the finished flow as an API endpoint or an embeddable chat widget on your client's website. It targets a different niche than Flowise (also in the catalog) - both tools build LLM graphs, but Langflow has a broader component catalog and is more often chosen when the flow needs to become the client's own API.
Who it's for- An agency or developer that builds AI features for a client and wants to give the client their own API instead of relying on an external service
- A company that wants a chatbot that answers based on its own documents, without handing the content over to a third-party SaaS
- Anyone who wants to compare several LLM models in one place before deployment
What you get with Langflow.
Your own container
Langflow runs in an isolated container with dedicated RAM and NVMe storage.

Every domain and subdomain automatically receives a certificate that renews itself.
Email on your own domain
Email accounts are included in your plan, with no limit on the number of mailboxes.
Backups
Daily off-site backup in every Box. Starting with Box L, you can restore backups from the dashboard.
Free migration

Which Box to choose for Langflow
It depends on what you use it for. You can change plans later from the dashboard without moving your data.
Getting started
Just the app, light traffic, one user
Box L
139 € / year
- 6 GB RAM
- 60 GB of storage
- SSH with sudo
- backups for 7 days
Higher usage
More data and more people at once
Box XL
299 € / year
- 12 GB RAM
- 150 GB of storage
- SSH with sudo
- backups for 14 days
Heavy traffic
Multiple apps at once or a service that generates revenue
Box XXL
819 € / year
- 24 GB RAM
- 300 GB of storage

You don't have to guess. Start with a smaller plan, and if you run out of RAM, we'll add more without restarting your app or moving your data.
What else can you fit? on the same Box
Langflow uses 2 GB of the 6 GB memory included with Box L. That leaves 3.8 GB and 50 GB of disk space, so you can fit up to 145 more apps from the catalog. No extra charge, because you pay for the Box, not the apps themselves.
Frequently asked questions
Does Langflow work without an API key for models?
The app itself works without a key, and you can build and test flows in the graph. You enter a key (OpenAI, Anthropic, Google, or a model on your own server, for example Ollama) when you want to use a model.
Does your data leave your Box?
Flows, keys, and run history stay in your Box. Only the query sent to the model you selected goes outside. With a model hosted on your own infrastructure, the content never leaves your infrastructure at all.
How much memory do you need?
Langflow itself is lightweight, so the model you connect is what matters. A Box L (6 GB RAM) is enough for a 7B model, while 13B and larger models require a Box XL.
Is Langflow actively developed?
Yes, it is an active LangChain project. The version in the Box is pinned to 1.13.0, so the environment is reproducible.
Do I need server administration skills?
No. We handle the container, domain, SSL certificate, and system updates. Click Langflow in the dashboard, and within seconds you'll have an address and password. If you want SSH access, you'll get full access with sudo, but you don't have to use it.
What if I run out of storage or memory?
You can change your plan from the dashboard, and additional memory is added without restarting the application. You don't need to move your data or set anything up again.
Can Langflow run on my own domain?
Yes. Connect your own domain or use the free saploapp.pl subdomain. The SSL certificate is generated automatically.
Who owns my data?
You do. Your data is stored in a dedicated container, not on a shared account. Every day, we make an off-site backup to a data center in Finland on every plan.
Can I run other apps alongside Langflow?
Yes. The number of apps and domains in your Box is unlimited. Your plan's memory and disk space are the limits.
What if I don't like it?
Saplo.io is not live yet. We'll add you to the waiting list and let you know when the first Box plans become available.
We are not the cheapest. For 5 € a month, you can get a shared hosting plan that will be enough for a simple website. Saplo makes sense when you want to run your own apps, have SSH access, and avoid sharing your server with a thousand unrelated sites.
