Entry Paid Tier (Monthly) $16 USD / mo Free / Custom
Pricing & Cost Architecture Monthly credit quota: Free tier provides 500 scrape credits/mo (1 page = 1 credit; 1 crawl = 1 credit per discovered page). Starter plan is $16/mo for 3,000 credits ($0.0053/page). Growth is $99/mo for 100,000 credits. Every user receives $30/month in free compute credits perpetually. Pay-as-you-go CPU starts at $0.000015/core-second; NVIDIA GPUs (T4 to H100) are metered per millisecond.
Key Engineering Insight Created after developers struggled with fragile Puppeteer scripts for RAG; its scraping cluster processes millions of web pages weekly with automated proxy rotation and stealth headers. Founded by Erik Bernhardsson (former CTO of Better and creator of Spotify's Annoy algorithm); designed to make cloud infrastructure and GPU clusters feel as seamless as a local Python import.

Strengths & Trade-Offs

Objective engineering evaluation of both platforms

Firecrawl Evaluation

Key Advantages

  • ✓ Converts complex JavaScript-rendered SPAs and shadow DOM into clean, structured markdown optimized for LLM tokenization
  • ✓ Includes built-in automated anti-bot bypass, residential IP rotation, and captcha handling with no external proxy configuration
  • ✓ Official Model Context Protocol (MCP) server support and official SDKs for Python and TypeScript

Limitations & Trade-Offs

  • ✕ AGPL-3.0 copyleft license requires open-sourcing modifications when self-hosting in proprietary environments
  • ✕ Credit consumption scales rapidly on deep recursive crawls across multi-page domains

Modal Evaluation

Key Advantages

  • ✓ Pure Python infrastructure as code: define container images and cloud jobs using simple '@app.function' decorators
  • ✓ Sub-2 second container cold starts with on-demand access to NVIDIA A100, H100, and L4 GPUs without provisioning
  • ✓ Automated horizontal scaling across thousands of parallel workers with built-in queueing and output streaming

Limitations & Trade-Offs

  • ✕ Proprietary cloud runtime with no self-hosted on-premise execution engine available
  • ✕ Workloads must be structured around Modal's Python decorator conventions and cloud serialization rules
