Langflow on Nodion: questions and answers
How do I deploy Langflow on Nodion?
Sign in to Nodion, open the Langflow preset and pick a project and a region. Nodion creates the app with a managed PostgreSQL database, an S3-compatible bucket and a 10 GB volume, sets the environment variables and starts the first deploy.
Is this the same as self-hosting Langflow?
You get your own Langflow instance in your Nodion project. The difference: Nodion runs the servers, so there is no machine of your own to install and maintain.
How much does it cost to run Langflow on Nodion?
The starting setup costs about 11 EUR per month: App DS-G2-2GB, 2 GB RAM 8 EUR, PostgreSQL DS-G2-256MB, 256 MB RAM 1.50 EUR, Volume 10 GB 1.50 EUR. Object Storage is billed by usage. Prices are net and billed per second. You can pick bigger sizes in the form.
What should I do after the first deploy?
Sign in with username admin and the generated superuser password from the application environment. There is no default password.
Which version of Langflow does Nodion deploy?
The preset sets the image langflowai/langflow:1.12.5. Your app keeps that image tag until you change it on the app's Processes tab.
Can I use my own domain for Langflow?
Yes. Every app gets a default hostname with HTTPS. Add your own domain on the app's Domains tab.
Where does Langflow run?
In the region you pick: EU Central (Germany), US East and US West (United States) or APAC Central (Singapore). Build, registry and runtime stay in that region.
