Is Octoparse free?

I have recently started using Octoparse as an alternative to other backup apps that I was using. I just wanted to confirm that Octoparse is free and that I can download it directly from its website? I have been using the app for a while and really like it. I am a bit concerned that it will not be free forever. The only way I can find to get a free version is by getting a coupon code. That is a bit of a hassle. Is there any way I can just download it directly from the app's website?

The OctoPose is free, but you need to buy the full version. However, there is a free version which can be downloaded from the app store. I have the free version and I love it. I have found it really useful. However, the only issue I have with the free version is that you have to manually add the apps you want to backup. It doesn't do it automatically.

Which are the Best Web Scraping Tools?

Grab from Python.org is a very useful web scraping tool. It has web scraping experience and can be used for both competitive and noncompetitive reasons. It's covered in detail by John Rose over at NetPython here. Grab is written in Python and runs either locally (via the Python interpreter) or on a remote server. Grab is also a great tool for educational purposes as it is pretty easy to use and covers a lot of the sites in detail.

Grab can scrape websites in 3 ways: From the command line (grab command, grab command -r, grab -p ). By file name (grab file.html or grab file.txt)

Or by url (grab www.google.com)

Grab also has the ability to do sessions. It can repeat the same scraping as a session (grab sessions/.) or as a batch (grab all/. If you want to run the grab tool but have it return results as soon as it has scraped, grab -p should be used. If you want to wait for it to scrape before returning results, it's best to use the batch-method.

Can Chrome extensions scrape websites?

I have to scrape a website with Chrome extensions. My first approach was Greasemonkey. Unfortunately, it doesn't work with some elements. Now I've read about Greasemonkey userscripts, but I don't understand how they work. Is there a way to scrape a website with user scripts? Answers with a source would be helpful.

The script must be hosted locally. Since you're writing the code to scrape the site you have to be an author (or at least a tester) of the site you wish to scrape. Greasemonkey scripts are designed to run on user websites. You must host your code on a web server you control, since the content of GM scripts is JavaScript external to the browser. You can host your code on a web server that is both internal and local to your computer (or a cloud server), but you'll need to verify that the content of the file is correct, since the script can be modified by the user. If you are playing in a sandbox (eg the extension is in the Chrome Web Store), then you'll be limited in your options. I haven't looked into it, but perhaps something like jsbin.com might work.
