Perfect for

Model training teams

Collect domain-specific datasets for pre-training and fine-tuning without custom crawlers.

RAG and evaluation pipelines

Build fresh eval sets and benchmarks from real docs and sites with preserved URLs.

RLHF and instruction data

Extract structured sections so you can generate prompts, pairs, and preference data in code.

Compliance-minded orgs

Scope allowed sources by domain and path so you can audit what goes into your training data.

How it works

Crawl approved sources

Crawl target domains and docs portals into structured, domain-specific text datasets so your models train on the same pages your users read, not a generic crawl of the public web.

Extract structure to JSON

Extract headings, sections, and metadata into JSON so you can generate instruction pairs, Q&A datasets, and RLHF prompts in code instead of hand-labeling examples.

Filter and scope the surface

Filter pages by domain, path, or custom rules so you can enforce which web content is allowed into training sets and answer “where did this come from?” with a concrete list of URLs instead of guesses.

Schedule refreshes

Schedule recurring Firecrawl crawls so fine-tuning datasets and evaluation sets stay fresh without rerunning scrape jobs every time something changes.

Export to your training stack

Export data in formats your training stack expects so PyTorch, TensorFlow, or custom orchestrators plug it in without brittle HTML parsers or cleanup scripts.

Discover new sources over time

Combine Firecrawl’s search and crawl endpoints so you can discover new relevant sources over time and grow or refresh datasets as your model scope expands.

Frequently
asked questions

Everything you need to know about this use case.
General
Teams use Firecrawl to build domain-specific pre-training sets, instruction and Q&A datasets for fine-tuning, reinforcement learning from human feedback (RLHF) preference data, and evaluation sets derived from real docs and sites. The pattern is simple: define domains and paths, crawl with Firecrawl, then turn the structured output into your preferred training format.
Each Firecrawl job can be scoped by domain, path, and custom filters so you only ingest the sources you’ve explicitly allowed. Because those settings live in code or config, you can review and diff what changed any time someone updates the training data surface.
Technical
Yes. You can schedule Firecrawl jobs to run daily, weekly, or on any cadence you need. Many teams refresh key domains regularly so their fine-tuned models and evaluation sets reflect the latest docs, policies, and product changes without one-off scraping runs.
Firecrawl exposes a simple HTTP API and SDKs. Most teams add a data collection step at the start of their pipelines that calls Firecrawl, writes structured outputs to object storage, and then hands those files to their existing preprocessing and training jobs.
Integration
Firecrawl is designed to respect robots.txt and standard web crawling conventions. You still own the decision about which sites to include and are responsible for making sure your AI training use complies with each site’s terms and any regulatory requirements.
Why Firecrawl?
The world's most comprehensive web data API. Our custom browser stack and semantic index deliver superior data quality across any website, handling more content types and edge cases than any competitor.
JavaScript rendering, dynamic content, and robust request handling built-in.
Process millions of pages with automatic rate limiting, caching, and distributed infrastructure.
Optimized scraping engine with parallel processing and smart caching for instant results.
Comprehensive docs, SDKs for all major languages, and dedicated support to help you succeed.
