Frequently asked questions
How does Stack0 compare to Firecrawl for extraction?
Both use AI to extract structured data from webpages. Stack0 focuses on single-page extraction with schema support, while Firecrawl also offers full-site crawling. For most API use cases, single-page extraction is what you need.
Does Stack0 support site crawling?
Stack0 focuses on page-level extraction rather than full-site crawling. You can batch multiple URLs, but we don't automatically discover and crawl entire sites. For targeted extraction, this keeps things simple and cost-effective.
How does pricing compare?
Stack0 charges $2 per 1,000 extractions with AI tokens included and no monthly minimum. Firecrawl has tiered plans starting at $9/month for the Hobby plan (3,000 credits/month). Stack0's usage-based model means you only pay for what you use, which is often more cost-effective for variable workloads.
Can I use custom prompts?
Yes. Stack0 supports custom prompts to guide the AI extraction. Tell it what to focus on, what to ignore, or provide specific instructions for handling edge cases.
What about the output format?
Stack0 supports auto, markdown, schema (JSON Schema), and HTML extraction modes. Schema mode gives you strongly typed output that matches your defined structure.
Is the AI extraction reliable?
Stack0 uses state-of-the-art LLMs for extraction. The AI understands page content semantically, so it continues working even when sites change their HTML structure.
