Stack Gems reviews 4 web scraping tools for LLMs: 4 free or open source. These are the top 4, each with its verdict and the Catch we would want to know before installing it.

VerdictApache-2.0 LLM crawler. Markdown-for-agents vs Scrapling/Agent Reach/Browser Use/Stagehand.
CatchVs Scrapling (adaptive scrape/crawl + MCP), Agent Reach (public-web CLI eyes), Browser Use/Stagehand (browser agents): Crawl4AI is an LLM-oriented crawler/extraction library, not a hosted scrape API, not a site-specific eyes CLI, and not a Playwright agent. You own proxies, blockers, rate limits, and site ToS.
Free / OSS · Freemium · 193k GitHub stars
VerdictAGPL+cloud scrape API. Freemium credits vs Scrapling/Crawl4AI self-run; license and Free-tier limits are loud.
CatchAGPL-3.0 on the open engine — network copyleft if you modify and offer it as a service. cloud: Free is only 1k credits/mo with low concurrency; Hobby starts ~$16–19/mo for 5k credits — past that you pay. Vs Scrapling/Crawl4AI (self-run libraries) and Agent Reach (zero-API-fee eyes CLI): Firecrawl is API-first with a metered cloud; self-host trades SaaS bill for AGPL+ops. Distinct from Scrapling/Crawl4AI — do not treat as the same card.
Free / OSS · OSS/MIT · 6.9k GitHub stars
VerdictOpen MCP for agents on your TradingView Desktop. Paid TV sub required; chart interface layer, not a trading bot.
CatchYou need a valid paid TradingView subscription plus Desktop with remote debugging enabled — the bridge does not bypass paywalls. Undocumented Electron internals can break on any TradingView update. Vs playwright-mcp / BrowserSkill / Hyperbrowser MCP: this is desktop TradingView CDP, not a general browser or scrape API. Not a trade-execution bot.
Free / OSS · OSS/MIT · 249 GitHub stars
VerdictMIT GTM catalog MCP when agents need operator maps for growth tools — not Apify scrape Actors and not a static awesome-list dump.
CatchRead-only catalog MCP — it does not execute vendor APIs for you; you still need each tool’s own keys when a workflow says so. Vs Apify MCP / generic awesome-lists: Apify runs Store Actors; this catch is GTM tool+workflow markdown as MCP prompts/tools. Vendor accuracy drifts — treat entries as starting maps, pin commits if you fork.
