Obscura + Ollama Local AI Web Scraping with a Rust Headless Browser

More

Summary

Fahd Mirza demonstrates a fully local AI web scraping pipeline combining Obscura — an open-source headless browser written in Rust — with a locally running Qwen 3.6 27B parameter model via Ollama. The core motivation is resource efficiency: standard headless Chrome deployments consume over 200MB of RAM and take seconds to initialize, while Obscura uses approximately 30MB and loads pages in around 85 milliseconds with no Node.js, Chrome, or dependency installation required — just a single self-contained binary.

The tutorial walks through the complete workflow: installing Obscura, scraping a live JavaScript-heavy website into clean Markdown, and piping that output directly to the local model for summarization into five bullet points. The entire pipeline runs on an Nvidia RTX A6000 with 48GB VRAM, and no data leaves the machine. Mirza wraps the pipeline into a reusable shell script that accepts any URL, enabling easy deployment at scale. He notes that production use will require pre- and post-processing to strip page headers and footers from scraped content.

The architecture section explains Obscura’s eight-crate Rust design: a CDP server routes WebSocket frames by session ID to a dispatcher, which calls page navigation handlers that fan out to three parallel lower-level packages handling HTTP fetch, HTML parsing, and V8 JavaScript execution. All pages share a single-threaded V8 isolate — the mechanism that keeps memory usage low. The model used, Qwen 3.6 27B, is highlighted for its tool-use support, which Mirza recommends as a prerequisite for models intended for agentic scraping workflows.
