Flowise is an open-source LLM orchestration platform you deploy and manage yourself. Neureus is the same capabilities — RAG, agents, multi-provider routing — as a managed API. No Docker, no VPS, no 3am pager alerts.
Flowise is free to use — but running it in production isn't. Here's what self-hosting typically costs per month for a small team.
| Cost item | Flowise (self-hosted) | Neureus |
|---|---|---|
| Docker + VPS (DigitalOcean 4GB) | $48/mo | — |
| PostgreSQL (managed) | $15/mo | — |
| Redis (session/queue) | $7/mo | — |
| Maintenance (DevOps hrs × rate) | $100–300/mo | — |
| Neureus Builder plan | — | $29/mo |
| LLM tokens (same volume) | ≈market rate | 10% below OpenRouter |
| Workers AI (Llama, Mistral, etc.) | ≈$0.10–0.90/1M | Free |
| Monthly total | $170–$370/mo + hours | $29/mo |
Self-hosting estimates for a production setup. Development-only setups cost less but aren't reliable for production traffic.

Flowise's visual builder is great for prototyping. For production code that your team can test, version, and deploy, the Neureus API is more maintainable.
// Flowise: visual flow → exported JSON → opaque runtime
// Neureus: the same RAG + chat flow in explicit, testable code
import { NeureuAI } from '@neureus/sdk';
const client = new NeureuAI({ apiKey: process.env.NEUREUS_API_KEY });
// Ingest your documents (once, or on update)
await client.rag.ingest({
url: 'https://your-docs-site.com/api',
chunkSize: 512,
overlap: 64,
});
// RAG + chat in one call
const { text, sources } = await client.ai.chat({
model: '@wai/llama-3.3-70b', // free via Workers AI
messages: [
{ role: 'system', content: 'You are a helpful assistant. Use the retrieved context.' },
{ role: 'user', content: userQuestion },
],
rag: { query: userQuestion, topK: 5 },
});
console.log(text); // grounded answer
console.log(sources); // source documents Flowise's visual workflow builder is genuinely excellent for rapid prototyping — drag LLMs, RAG retrievers, and tools onto a canvas and connect them without writing code. If you're exploring AI capabilities with non-developers or need to iterate on flows without coding, the visual interface has real value.
Flowise is also fully open-source and self-hostable. If your organization has data residency requirements, an air-gapped environment, or compliance constraints that preclude using external APIs, self-hosting is the right choice. Neureus runs on Cloudflare's edge — if that doesn't meet your data residency requirements, Flowise on your own infrastructure may be the better fit.
Finally, if you want to extend the orchestration engine itself — modify how retrievers work, add custom node types to the canvas, or fork the UI — Flowise's open-source nature enables that. Neureus is a managed API; you call it, you don't fork it.
Neureus handles the AI stack. You handle the product. 500 Neurons/month free, no credit card.
