Best Kadoa alternatives
Kadoa is a no-code, AI‑powered data extraction tool that autogenerates scrapers, self‑heals when layouts change, and lets you schedule recurring jobs via a credit‑based API. But if you've used it, you may have encountered some issues like heavy monitoring jobs burning through credits fast, having no place to drop to code or self-host, or a lack of options for sites with strict anti-bot measures. The tools below remove these problems.

Website Content Crawler
Website Content Crawler is a specialized scraping tool built for AI training data. Input the URLs you want to scrape, and it does a deep crawl and retrieves data for you to export in multiple formats. It saves cleaned content as Markdown, plain text, or HTML, perfect for LLM fine‑tuning or Retrieval-Augmented-Generation (RAG). Features like headless Firefox, proxy rotation, login, CAPTCHA bypass, and infinite scroll handle the hard stuff for you. You can push results straight to LangChain, LlamaIndex, Pinecone, and other vector databases.
Crawl4AI
Crawl4AI is an open‑source Python framework with high‑performance parallel crawling, smart session and proxy management, and Markdown export for LLMs. It's a great option if you want full control of self-hosting or to avoid per-run fees.

LLM Scraper
If you need flexible, code‑level extraction inside a Node/TS stack, LLM Scraper is a TypeScript library that uses LLM function‑calling to turn any page into structured JSON. It's a great option for AI training, research, and market intelligence.

GPT-Crawler
GPT-Crawler is an open-source GitHub project that crawls docs, outputs knowledge files, and builds custom GPTs or RAG corpora in minutes. It offers headless browser support for JavaScript-rendered sites and can generate knowledge files to create custom GPT models from one or multiple URLs. This is a good option if you’re assembling a searchable knowledge base for support or docs.

Rag Web Browser
If you want to feed live web snippets into a retrieval‑augmented chatbot, Rag Web Browser is ideal. It has a Google‑search‑first workflow. It finds top results, then pipes each URL through Website Content Crawler for clean context. This makes it a great choice for AI-powered search and knowledge retrieval.

Jina.ai
Jina.ai is an AI‑native indexing platform with ReaderLM for HTML→Markdown conversion and vector search APIs. It transforms discovered URLs into vectorized representations for AI-driven search engines and applications, making it helpful for search‑first pipelines and instant vector embeddings.
