Stop updating AI prompts in every workflow — centralized prompt management with native n8n node

Hey everyone!

I've been using n8n for automation projects and kept running into the same problem: AI prompts scattered across dozens of workflows.

Every time I wanted to tweak a prompt, I had to:
- Find which workflow(s) use it
- Update each one manually
- Hope I didn't break anything
- No way to A/B test different versions

So I built xR2 — a centralized prompt management platform with a native n8n community node.

How it works with n8n:

1. Create your prompt in xR2 with variables like {customer_name}, {issue}
2. In n8n, add the xR2 node → Get Prompt action
3. Fill in variables right in the node UI (Variable Values section) — supports n8n expressions like {{ $json.customer_name }}
4. Get the fully rendered prompt back — ready to pass to OpenAI/Claude/etc.

No Code node needed for variable substitution — the xR2 node handles it natively. If you skip a variable, it falls back to the default value from your prompt definition.

What you get:
- Change prompts instantly without touching workflows
- Version control (draft → testing → production)
- A/B test different prompts to see which converts better
- Track events (did the user complete signup after seeing this prompt?)
- Variables rendered server-side — no extra nodes in your workflow

Example workflow:
Webhook → xR2 (Get Prompt with variables) → OpenAI → Send Email → xR2 (Track Event)

Install via: Settings → Community Nodes → search "n8n-nodes-xr2"

Pretty cool and looks like a lot of work went into this. Hoped it was a free share, but we all have to eat. Looks good, but you may want to change the pricing a bit. IMO $20/m is a steep ask.

Thanks for checking it out!

There’s a free tier that covers up to 100 prompt requests/month — enough to get started and test things out. But I hear you on the $20/month for the next step.

Curious — what would feel fair for you? And what’s your use case — how many workflows are you running with AI prompts?

Straight up. I’m not a potential client. I was expecting this to be a free workflow. I can probably build this myself if need be.

I would re-frame how you’re going about selling this. Normal non tech people will never get to the point of needing this. Techy people could build it themselves with time. I would pivot to an enterprise model with integration and support.

I could see this being a tool in some huge ai pipeline or something. An enterprise company running 100s of prompts has a much bigger need than a dev running maybe 5.

Something along the lines of your original pitch but with added support, maintenance, and integrating into existing codebases and software. IMO an enterprise company would be willing to pay if they know you will maintain and support it, they’d be much more willing to include it in their pipeline vs random a fly by night ai saas company. Just my 1c.

Here’s a walkthrough showing how it works in practice
