Firecrawl: Pricing, Features & Alternatives

Firecrawl became the default scraping layer for AI apps by solving the part that actually hurts: it renders JavaScript, rotates proxies, follows sitemaps and hands back clean markdown instead of raw HTML. Pricing is credit-based on top of a flat monthly tier — Hobby at $19 covers 5,000 credits. It is also open source under AGPL, so the whole thing can be self-hosted if you would rather run the proxies yourself.
