Running collection jobs on a CI scheduler: secrets handling, artifact storage, failure alerts, and why runner egress IPs make proxies necessary.
Where Zapier-style platforms allow proxy configuration, the limits of their HTTP steps, and the self-hosted relay pattern that works around them.
Export paths from a scraper to a spreadsheet: CSV pitfalls, direct XLSX generation, Power Query refreshes, and the data types that break on import.
How to design a benchmark that actually predicts production: same target, same proxies, measuring success rate, time and cost per page rather than raw speed.
A selection guide by target type and budget: datacenter for public bulk data, residential for defended pages, mobile for the hardest, plus how to test first.
A tour of open-source scraping libraries across languages, what each is genuinely good for, and how to judge a project's health before depending on it.
What Crawl4AI does well, where it falls short, and the proxy configuration needed to make it dependable on defended targets and larger runs.
Practical prompts for generating and repairing parsers, plus the caveats: selectors go stale, generated code needs review, and extracted data needs checks.
Combining a fetch layer, a browser fallback, LLM extraction and proxies, with an honest look at where the cost concentrates and how to keep output valid.
Using the Playwright MCP server so an AI agent can drive a browser, with a proxy configured so the agent's traffic is geo-correct and rate-aware.
The difference between a local headless browser and a managed scraping browser, what you actually buy with the latter, and how to evaluate the trade-off.
Playwright, Puppeteer, Selenium and managed scraping browsers compared on language support, waiting behaviour, parallel contexts and proxy handling.
Your TLS and HTTP/2 handshakes identify your client regardless of headers. How the technique works, why libraries look unlike browsers, and the fix.
429, 403, soft bans and tarpits each mean something different. Here is how to interpret each response and the correct reaction to every one.
What FlareSolverr does, how to wire it into a scraper, its real limitations, and why it is a workaround rather than a durable strategy for defended targets.
The interstitial is a risk check driven by your IP and client fingerprint. Here is what triggers it, why hammering makes it worse, and how to reduce it.
Most challenges come from a low-trust IP. How residential and mobile addresses lower the risk score, and how to measure challenge rate as a quality metric.
Why challenges appear, how to lower the risk score so they stop, and an honest assessment of solver services including cost, accuracy and terms of use.
Tell a genuine outage from a soft block, honour Retry-After, and design backoff that recovers instead of escalating a rate limit into a ban.
499 is non-standard and means the client closed the connection before the server responded. How to tell an aggressive timeout from server throttling.
Clean, pre-filtered residential and mobile proxies, sign up and send your first request in minutes.
