Deploy and Host Flowise (w/ vector store) on Railway

Flowise is an open-source visual builder for AI agents, chatbots and RAG. This template runs the official release with your admin account created on deploy, and a private Postgres that keeps your work and doubles as Flowise's vector store.

About Hosting Flowise (w/ vector store)

Deploy with your email and a password: a Setup service creates your Flowise admin with them, so nobody else can claim the sign-up page. Flows, credentials and uploaded files survive redeploys. Sign in at your Flowise URL; the Postgres vector store works without a host or password to fill in.

Common Use Cases

Chatbots that answer from your documents
AI agents calling tools and APIs
