We Built a Reddit Monitor in 2 Hours (Process as a Service Demo)

WRIO (webRobotics IO) is an AI-native business automation platform that helps teams research, automate, and scale their operations. WRIO Reddit Responder is a specialized tool within the platform that monitors subreddits for relevant discussions, filters opportunities using AI, and generates draft comment ideas with real Reddit examples.

TL;DR:

  • Built wr.io/wrio/reddit-responder as a working demo of Process as a Service (PraaS)
  • Powered by Cloudflare Workflows + BizCom engine — same stack used by enterprise clients
  • Monitors Reddit RSS → filters with AI → (soon) generates answers
  • This is a live demo — showing our engine in action
  • Just secured €500k EU grant to accelerate development 🎉

What is Process as a Service (PraaS)?

Traditional SaaS: You build UI, backend, database, auth, billing... then finally your core logic.

PraaS flips this:

  1. Define your business process (workflow) in JSON-LD
  2. Engine handles execution, storage, logging, rate limits
  3. Ship a working product in hours

Think "Serverless for business logic."

The Demo: Reddit Monitor

What It Does (Right Now)

Input: Subreddit + keywords (e.g., r/SaaS, "automation")

Process:

  1. Fetch latest posts via RSS
  2. Filter with AI (Gemini 2.0 Flash) — relevance score > 70
  3. Extract opportunities (title, link, why it's relevant)
  4. Save to your Activity Inbox (Coming soon)

Output: List of relevant threads + AI reasoning

Tech Stack (Production-Ready)

  • Cloudflare Workflows — Durable execution (survives crashes)
  • R2 Storage — Logs, definitions, results
  • D1 Database — Workflow state tracking
  • Server-Sent Events (SSE) — Real-time progress updates
  • BizCom Engine — Same one running our enterprise processes

This is a live demo. It runs on the actual platform we sell to businesses, showcasing our engine's capabilities.

Why This Matters (Build in Public Context)

Problem We're Solving

Every automation tool (Zapier, Make, n8n) focuses on integrations.

We focus on processes — complex, multi-step workflows with:

  • Conditional logic (if/else, loops)
  • Human-in-the-loop approvals
  • Audit trails
  • KPI measurement
  • Embeddable widgets for clients

The Vision

Imagine building:

  • Invoice Chasing Bot (automated debt recovery)
  • Lead Finder (Clay alternative, $49 vs $349/mo)
  • Customer Feedback Loops (NPS + auto-follow-up)

...in hours, not months.

That's PraaS.

What's Next (Roadmap)

Phase 1 (Jan 2026) ✅

  • Reddit Responder demo
  • Real-time progress UI
  • Free tier (10 runs/day)

Phase 2 (Feb 2026)

  • LinkedIn Auto-Responder
  • Activity Inbox integration (one feed for all workflows)
  • "Reply Now" quick actions

Phase 3 (Mar-Apr 2026)

  • Workflow Marketplace (buy/sell processes)
  • Visual BPMN Editor (no-code)
  • Embeddable widgets for client websites

Long-Term

  • AI Skill Store (reusable AI nodes)
  • Multi-tenant SaaS template (ship your own PraaS platform)

The EU Grant Story

We just received approval for €500,000 EU funding to:

  1. Scale infrastructure (Cloudflare Enterprise)
  2. Hire workflow engineers
  3. Build AI marketplace
  4. Run pilot programs with 50+ SMEs

This means faster shipping — expect weekly updates.

Frequently Asked Questions

Is this just another no-code tool?

No. We're code-first (JSON-LD definitions) with visual editor coming later. Think Terraform for business processes. We prioritize developer experience and version control over drag-and-drop simplicity, although a visual editor is on the roadmap.

Can I build my own workflows?

Yes! Sign up for early access on our platform. You can define custom workflows using our JSON-LD schema, allowing for complex logic, branching, and integrations that go beyond simple linear automations.

Why Cloudflare Workflows, not AWS/Azure?

Global edge execution, $0 cold starts, built-in Durable Objects. Perfect for automations. Cloudflare's network ensures your workflows run close to your users, providing low latency and high reliability without the overhead of managing traditional serverless infrastructure.

What about data privacy?

EU-first. All data in Cloudflare EU regions. GDPR-compliant by design. We take data sovereignty seriously and ensure that your business data and your customers' data are handled with the highest standards of privacy and security.

How does the pricing work?

We offer a generous free tier for developers and small teams to get started. As you scale, our pricing is based on execution volume and storage usage, ensuring you only pay for the value you get. Enterprise plans with dedicated support and SLAs are also available.

Let's Build in Public Together

This post is part of our Build in Public journey. We'll share:

  • Weekly metrics (runs, users, revenue)
  • Technical breakdowns (architecture, costs)
  • Failures and pivots

If you care about process automation or AI-powered workflows, this is your chance to shape the product.
