Choose trafilatura if…
- Tags unique to trafilatura: article-extractor, corpus-builder, crawler, html-to-markdown.
- When you need a tool that supports multiple output formats, including less common ones like TEI and XML, for detailed text and metadata extraction.
- More recently updated (last pushed Aug 15, 2026).
When NOT to use trafilatura
- When your project strictly requires a tool under the GPL license, as trafilatura is now distributed under the Apache 2.0 license.
- If your use case demands real-time scraping capabilities, as trafilatura focuses more on accuracy and quality of extracted content rather than speed.
Choose data-juicer if…
- Tags unique to data-juicer: foundation models, instruction-tuning, large-language-models, synthetic-data.
- Also covers Model Training.
- data-juicer ships Docker support for self-hosted deployment.
- When you need to preprocess large datasets specifically for training large language models (LLMs) with pipelines that support sophisticated processes like instruction tuning.
When NOT to use data-juicer
- If your project does not involve foundational AI model training or if you do not require advanced data processing capabilities such as synthetic data generation.
