TL;DR: Compare mitmproxy, Fiddler Everywhere, HTTP Toolkit, and Proxyman by debugging task. Use a controlled trial to verify capture, evidence sharing, and certificate cleanup.
TL;DR: Compare Octoparse, Browse AI, Apify, and Scrapy by extraction ownership and delivery needs. Build a pilot that checks completeness, freshness, and migration readiness.
TL;DR: Design a website collector from record definition to verified delivery. Bound source scope, choose an execution model, validate observations, and recover incomplete runs.
TL;DR: The best PhantomJS alternative depends on what your old script did, because PhantomJS development was suspended in March 2018. Use Playwright for most new work, Puppeteer for the shortest Node.js port when you only need Chrome, and Selenium if your tests already run on a WebDriver grid. If the page is server-rendered, an HTTP client and a parser will do.
TL;DR: The right choice depends on whether Scrapy's bottleneck is rendering, blocking, language fit, or operations. Keep or extend healthy spiders when possible; use browser tools for interactive pages, hosted platforms for operations, lightweight stacks for bounded static jobs, and managed APIs when request infrastructure is the constraint. Validate the shortlist with a cost model and a representative proof of concept.
TL;DR: Compare Octoparse, Browse AI, Apify, and Playwright by authoring model. Preserve navigation, record identity, and delivery behavior when replacing Web Scraper.
