webclaw v0.7.0
Browser
• Local JavaScript rendering with --render auto
• JS rendering in crawls, batches and the MCP server
• Page actions: click, scroll, type before extracting
• Gets past Cloudflare challenges (--solve, 15/16 pages)
• Every local render presents as regular Chrome
• Persistent browser profile between runs
• Block images, fonts or media while rendering
• Capture a page's network responses
• Screenshots, PDF, MHTML and WARC output
Extraction
• --query keeps only what answers a question (92.7% recall in 781 tokens vs 7,022 for the full page)
• CSS selectors and XPath 1.0
• Find elements by text, or every element like an example
• Data tables as JSON
• Chunks for retrieval
• Markdown with numbered link citations
• Hidden elements dropped from content
Crawling
• Worker-pool crawler that sees links, redirects and Crawl-delay
• Respects robots.txt by default
• Crash-safe crawls with streamed JSONL and checkpoints
• Query-guided crawling that stops once the answer looks found
• Site URLs from the Common Crawl index with --map
• Opt-in disk cache
MCP and packaging
• MCP over streamable HTTP with a bearer token, 14 tools
• Python package bundling the CLI
• One-command benchmarks against open-source extractors
Licence is now AGPL-3.0-only.

Webclaw retweeted
webclaw crossed 1,800 stars on GitHub this week.
It started because scraping APIs charge you to fight Cloudflare and lose.
Now 1,800 of you think a Rust engine you can read, fork, and self-host is the better deal. Thank you.
Back to shipping.

No card. A human reads every application within a few days.

You keep an X tab open just to watch one account post.
That's a cron job with anxiety.
X Monitors runs it for you. Point one at a profile, a keyword, a list, or a tweet's replies.
Filter by likes, language, or keyword and skip the retweets.
Every match hits your Discord, Slack, or webhook about a minute after it posts.
Build one no-code in the dashboard, or call it from Python, TS, or Go.
Live now → webclaw.io
Next step: 2000 ✨
+1,500 stars ⭐
I built webclaw to turn any website into clean markdown an LLM can read. It's now a CLI, an MCP server, a REST API, and SDKs for JS, Python, and Go.
Everyone who starred, filed an issue, or sent a PR got it here. Thank you. Plenty left to build.

webclaw.io just landed its 6th sponsor: MangoProxy.
Residential, ISP, datacenter, and mobile proxies across 200+ locations. That's the access layer a scraper leans on when sites start blocking you.
Use code 0XMASSI for 8% off their ISP static proxies:

One Reddit search gave me 10 people describing a problem my product solves.
Then ~15 lines ranked them by buying intent, so I reply to the ready ones first. One search call, one extract call.
webclaw.io + the JS SDK. Code below.
