I built a better search engine for n8n workflows (with tutorials & verified templates)

The Problem

  • Search experience – Finding a specific n8n use case (e.g., “Notion to DeepSeek with error handling”) is difficult in a forum‑style community.
  • The “black box” JSON – Downloading a template, importing it, and discovering that it requires complex setup or simply doesn’t work.

The Solution: n8nworkflows.world

A curated library of free, verified n8n workflow templates that include:

  • Extracted “how‑to” tutorials next to each download button.
  • Instant preview of the workflow logic before importing.

The goal isn’t to replace n8n’s UI but to provide frictionless search and X‑ray visibility into each workflow.

Tech Stack

LayerTechnologyReason
FrontendNext.js 14 (App Router)Fast SSR, SEO‑friendly so templates are discoverable on Google
DatabaseSupabase (PostgreSQL)Stores JSON plus enriched metadata (tutorials, step‑by‑step guides) for 6,000+ workflows
VisualizationReact FlowQuick preview of the node graph
Data PipelinePython + PlaywrightAggregates, cleans, and verifies public templates

Implementation Highlights

Parsing & Visualization

  • Used React Flow to parse the n8n JSON structure.
  • Wrote a parser that maps n8n’s coordinate system [x, y] to React Flow’s {x, y} format and reconstructs connection logic so edges render correctly.

Enriching the Data

  • Extracted notes and description fields from the n8n JSON and displayed them as structured “How to use” guides beside the download button.
  • Users can see required credentials (e.g., “Needs a Notion API Key”) before downloading.

Search Performance

  • Indexed json_content and metadata columns in Supabase for granular searching.
  • Searches can match specific nodes, not just titles.
    • Example query: "OpenAI + Pinecone" returns workflows that contain both nodes, filtering out irrelevant results.

Features of the Template Search Engine

  • Better Search – Filter by node type, category, or use case.
  • Verified Logic – Curated templates that are practical and functional.
  • Tutorials Included – Clear guides extracted from the workflow metadata.
  • Free & Fast – No paywalls, one‑click copy/download.

Open Source Data

While the UI code remains private for now, the curated list of workflow data is open‑sourced:

Developers can use the dataset for their own projects.

Try It Out

Let us know if the search finds what you need and whether the extracted tutorials are helpful.
