Nodeman - Self-Hosted AI SaaS Workflow Studio | JavaScript Application

Nodeman — AI Workflow Studio (SaaS, React + Node + Postgres)

Launch a credit-based AI image & video generation SaaS on your own domain in under an hour. Nodeman is a complete, production-ready Node.js + React application: a node-graph canvas where customers chain 20+ AI models (image, video, audio, voice, motion), a full Stripe billing engine, an admin panel for everything (templates, pricing, customers, branding, models), and a switchable auth system that works out of the box with no third-party signup required.

⚠️ Important: third-party services and their costs

This item is a self-hosted JavaScript application. To run the AI features and the SaaS billing flow, you will create accounts with several external services. These services bill you directly and their fees are separate from the one-time purchase price of this item:

• Replicate — required, pay-per-generation. Hosts every AI model (image, video, audio). You are charged by Replicate per second of model compute used by your customers.
• Stripe — required for paid plans and credit top-ups. Stripe charges its standard processing fee on every transaction (no monthly fee).
• Clerk — optional. The built-in email + password auth is the default, so Clerk is only needed if you choose the hosted-auth provider from the admin panel. Clerk has a free tier; paid tiers apply above its MAU threshold.
• Resend — optional. Used for transactional email (password reset, low-credit warnings). Resend has a free tier; you can also point the app at any SMTP provider instead.
• Database hosting — required (Supabase, Neon, Railway, Render, RDS, or self-hosted Postgres). Most providers have a free tier sufficient for early traffic.

This item ships the application source and all integration code. It does not include any prepaid credits, API quota, or third-party subscriptions. Plan for those usage fees alongside your business model — pricing the credit pack so it covers Replicate + Stripe per generation is how you stay profitable.

Live Demo

Demo URL: nodeman-ai-workflow-studio.up.railway.app

One-click sign in — demo accounts appear at the top of the login page:

• Customer: customer@mail.com / password
• Admin: admin@mail.com / password

First request after idle may take ~30 seconds while the free-tier dyno wakes up. Subsequent requests are instant.

Why Nodeman is different

Most “AI generator” scripts on CodeCanyon are thin single-prompt wrappers around one API. Nodeman is a visual workflow canvas: customers drag nodes, connect outputs to inputs, and chain a face reference into a video model into a music-bed generator without writing a line of code. It scales from “make me a single image” to “produce a 6-shot cinematic ad with voiceover” in the same UI.

• Node-based canvas — not a form. Pan, zoom, connect, group, save, version, share.
• 20+ AI models built in — Veo 3.1, Kling v3 Pro, Hailuo 2.3, Flux 2 Pro, Imagen 4, Seedream 5, Runway Gen4, MiniMax Speech HD, MusicGen, and more via Replicate.
• Three auth options, swappable from the admin panel — Built-in email + password (default, no third party), Clerk (hosted, social login), or Supabase Auth.
• 20 curated starter templates + 8 public workflows + 8 seeded customer projects ship in the box. Your demo is never empty.
• Pre-built bundle ships in the repo — deploys to Render/Railway free tier without OOM during the Vite build.
• Mobile responsive across landing, login, pricing, terms, privacy. Tested via Playwright.
