This tool was previously known as TagUI for Python. More details on the name change, which is backward compatible so existing scripts written with
import tagui as tandt.function()still work.
To install this Python package for RPA (robotic process automation) -
pip install rpa
To use it in Jupyter notebook, Python script or interactive shell -
import rpa as rNotes on different operating systems and optional visual automation mode -
- 🏳️🌈 Windows - if visual automation is cranky, try setting your display zoom level to recommended % or 100%
- 🍎 macOS - Catalina update introduces tighter app security, see solutions for PhantomJS and Java popups
- 🐧 Linux - visual automation mode requires special setup on Linux, see how to install OpenCV and Tesseract
RPA for Python's simple and powerful API makes robotic process automation fun! You can use it to quickly automate repetitive time-consuming tasks on websites, desktop applications, or the command line.

r.close()See sample Python script, the RPA Challenge solution, and RedMart groceries example. To automate Chrome browser invisibly, see this simple hack. To run 20-30X faster, without normal UI interaction delays, see this hack. You can even run on your phone browser using this Colab notebook (eg datascraping in headless mode).
An element identifier helps to tell RPA for Python exactly which element on the user interface you want to interact with. For example, //*[@id="email"] is an XPath pointing to the webpage element having the id attribute "email".
-
🌐 For web automation, the web element identifier can be XPath selector, CSS selector, or the following attributes - id, name, class, title, aria-label, text(), href, in decreasing order of priority. Recommend writing XPath manually or simply using attributes. There is automatic waiting for an element to appear before timeout happens, and error is returned that the element cannot be found. To change the default timeout of 10 seconds, use timeout() function.
-
📸 An element identifier can also be a .png or .bmp image snapshot representing the UI element (can be on desktop applications, terminal window or web browser). If the image file specified does not exist, OCR will be used to search for that text on the screen to act on the UI element containing the text, eg r.click('Submit Form.png'). Transparency (0% opacity) is supported in .png images. x, y coordinates of elements on the screen can be used as well.
-
📄 A further image identifier example is an image of the window (PDF viewer, MS Word, textbox etc) with the center content of the image set as transparent. This allows using read() and snap() to perform OCR and save snapshots of application windows, containers, frames, textboxes with varying content. Also for read() and snap(), x1, y1, x2, y2 coordinates pair can be used to define the region of interest on the screen to perform OCR or capture snapshot.

TagUI is a leading open-source RPA software 🤖 with tens of thousands of users. It was created in 2016-2017 when I left DBS Bank as a test automation engineer, to embark on a one-year sabbatical to Eastern Europe. Most of its code base was written in Novi Sad Serbia. My wife and I also spent a couple of months in Budapest Hungary, as well as Chiang Mai Thailand for visa runs. In 2018, I joined AI Singapore to continue development of TagUI.
Over the past few months I take on a daddy role full-time, taking care of my newborn baby girl and wife 🤠🤱. In between nannying, I use my time pockets to create this Python package built on TagUI. I hope that RPA for Python and ML frameworks would be good friends, and pip install rpa would make life easier for Python users.
At only ~1k lines of code, it would make my day to see developers of other languages port this project over to their favourite programming language. See ample comments in this single-file package, and its intuitive architecture.
