Assumptions you can change
Self-hosting Langflow usually means an app server, a database and a cache or worker. Hours are for one engineer; the server cost is a typical cloud VPS with backups and grows with the number of people using it.
Not included: paid editions or features of Langflow (see What's free?), large data migrations, and compliance work. All amounts in US dollars at list price; your negotiated price may differ.
