PulsarRPAPro README

English | 简体中文 | 中国镜像

PulsarRPAPro is the professional version of PulsarRPA, featuring an upgraded server, a collection of top e-commerce site scraping examples, and an advanced AI-powered applet for automatic data extraction.

Never write another web scraper. PulsarRPAPro learns from the website and delivers web data completely and accurately at scale.

There are already dozens of scraping cases for the most popular websites, and we are constantly adding more.

• Web UI: a simple yet powerful web interface to manage spiders and download data
• Machine learning: automatically extract every field in webpages using unsupervised machine learning, generating extraction rules and SQLs
• Data quality assurance: smart retry, accurate scheduling, web data lifecycle management
• Large scale: fully distributed, designed for large-scale crawling
• Simple API: a single line of code to scrape, or a single SQL query to turn a website into a table
• X-SQL: extended SQL to manage web data — web crawling, scraping, content mining, and web BI
• Bot stealth: IP rotation, web driver stealth, and anti-ban mechanisms

docker-compose -f docker/docker-compose.yaml up
java -jar PulsarRPAPro.jar
java -jar PulsarRPAPro.jar harvest "https://www.amazon.com/b?node=1292115011" -diagnose -refresh

Build from Source

Add the following lines to your .m2/settings.xml:

<mirrors>
    <mirror>
        <id>maven-default-http-blocker</id>
        <mirrorOf>dummy</mirrorOf>

</mirrors>

git clone https://github.com/platonai/PulsarRPAPro.git
cd PulsarRPAPro
./mvnw clean && ./mvnw
cd PulsarRPAPro/target/

# Don't forget to start MongoDB
docker-compose -f docker/docker-compose.yaml up

For Chinese developers, we strongly suggest following this guide to accelerate the build process.

Run the Standalone Server and Open Web Console

java -jar PulsarRPAPro.jar serve

If PulsarRPAPro is running in GUI mode, the web console should open within a few seconds, or you can open it manually at:

http://localhost:2718/exotic/crawl/

Run Auto Extraction

You can use the harvest command to learn from a set of item pages using unsupervised machine learning.

java -jar PulsarRPAPro.jar harvest "https://www.amazon.com/b?node=1292115011" -diagnose -refresh

The URL in the command should be a portal URL, such as a product listing page URL.

PulsarRPAPro will visit the portal, identify the optimal set of links for item pages, retrieve those pages, and analyze them.

Here is the full page of the auto extraction result in HTML format:

Explore the PulsarRPAPro Executable Jar

Run the executable jar directly for help and to explore more features:

java -jar PulsarRPAPro.jar

This command will print the help message and some of the most useful examples.
