Not every page needs a browser. If the data is already in the HTML, a scraping API is often enough. Free tiers, scraping APIs for LLMs: - Firecrawl: 1,000 credits/mo - Crawl4AI Cloud: 1,000 credits/mo - Jina Reader: 10M tokens - Apify: $5 usage/mo webagentstack.dev
Browsing isn't enough. Web agents also need search. Search APIs built for agents, and their free tiers: - Exa: $10 credits/mo - Tavily: 1,000 credits/mo - Parallel: $5/mo - Brave Search API: $5 credits/mo - Serper: 2,500 queries Compare them all at webagentstack.dev
Builders: what breaks first when your web agent hits production? a) bot detection / CAPTCHAs b) flaky selectors / layout changes c) cost per task d) logins & session state Reply with the one that cost you the most hours. We'll share the tally.
Picking a web agent stack still means a tab per vendor: pricing pages, READMEs, Discords, benchmarks nobody can reproduce. We're putting cloud browsers, agent SDKs, browser MCP servers and web data APIs side by side, with public data. Web Agents Stack, Oct 30.
@Tiny_Fish Thank you, TinyFish! You're already in: TinyFish is listed in the Web Agents Stack directory ahead of our Oct 30 launch at webagentstack.dev. We'd love to stay in touch, we'll follow up with a few details soon.
Picking a stack for a web agent today: 6 pricing pages, 3 READMEs, a Discord, someone's blog benchmark. There's no single place to compare cloud browsers, computer-use agents, web data APIs and proxies side by side. So we're building one. Web Agents Stack.
A web agent stack usually has 4 layers: 1. Browser infra: Browserbase, Steel, Kernel 2. Automation driver: Playwright, Puppeteer 3. Agent framework: Browser Use, Stagehand, Skyvern 4. Observability: Laminar We map the tools in each layer at webagentstack.dev #AIAgents
