Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 13 nodes and runs when someone submits an n8n form (“Enter Website URL and Settings”). Along the way it connects Supabase Vector Store and Embeddings Google Gemini. It also calls api.apify.com over HTTP.
How it runs
Trigger: When someone submits an n8n form (“Enter Website URL and Settings”).
- Set Data in Correct Request Format (Edit Fields (Set)): sets 4 fields: url, scrapeAll, maxCrawlPages…
- Prepare Settings for Apify Web Scraper (Switch): routes items into 2 branches
- No Limit to Number of Scraped Pages? (If): checks a condition and branches into true / false
- Run Apify Scraper: Scrape 1 URL Only (HTTP Request): calls api.apify.com (POST)
- Run Apify Scraper: Scrape All - No Limit (HTTP Request): calls api.apify.com (POST)
- Run Apify Scraper: Scrape All - w/Limit (HTTP Request): calls api.apify.com (POST)
- Clean Data (Edit Fields (Set)): sets 2 fields: url, markdown
- Improve Content Structure Quality (Code): runs custom JavaScript code
- Supabase Vector Store: stores documents in the Supabase vector store, with embeddings: Embeddings Google Gemini; document loader: Default Data Loader
Services it uses
HTTP calls to: api.apify.com
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
