TagUI RPA Tool

AI Singapore is now maintaining and developing TagUI tool - a Robotic Process Automation (RPA) tool - which can be used for automating user interactions with web browsers or other applications. The intention is to add AI capabilities to TagUI while keeping it open-source.

Key features of the tool include cross-platform implementation (macOS, Linux, Windows), integration with R & Python for big data and AI use cases, execution of automation flows in 20+ human languages or JavaScript, and visual automation of applications including OCR capabilities.

Features

  • automate Chrome visibly or headlessly
  • visual automation of websites and desktop
  • write in 20+ human languages & JavaScript
  • Chrome extension for recording web actions
  • R & Python integration for big data / AI / ML
  • CLI, REST API, advanced API calls covered

Why This

The goal of UI (user interface) automation is to reproduce cognitive interactions that you have with websites or your desktop, so that your computer can do it for you, base on your schedule or conditions. TagUI helps you rapidly automate your repetitive or time-critical tasks - use cases include process automation, data acquisition and testing of web apps.

Read on for more info or jump right into the flow samples section to see examples of TagUI automation in natural-language-like syntax. This is a full-feature and free open-source tool, so there's nothing to upgrade to or any paid subscription. To feedback suggestions or bugs, raise an issue or email ksoh@aisingapore.org. Originally developed by a test automation engineer to avoid writing chunks of code when automating web interactions.

How It Works

TagUI converts your intentions in different human languages into lines of working JavaScript code that perform web automation. Under the hood, it uses Chrome DevTools Protocol, Sikuli, CasperJS, PhantomJS & SlimerJS.

Conditions can also be written in natural language for making decisions or checking webpage. No further backend coding or step definition is required. This makes it easy for rapid prototyping, deployment and maintenance of web automation, whether you are a developer or not. The language engine supports over 20 languages and can be modified or extended easily by users to improve accuracy or add more languages.

The automation flow can be triggered from scheduling, command line (in natural language), API URL, email etc. Everything happens headlessly in the background without seeing any web browser, so that you can continue using the computer or server uninterrupted. Running on a visible web browser is also supported, using Chrome or Firefox browser. API or command calls can be made with a single line to integrate with other services or apps. Continuous integration with CI/CD tools is possible using CasperJS framework and TagUI's Chrome integration.

If you know JavaScript and want to be more expressive, you can even use JavaScript directly in the flow. If not, you will still enjoy friendly but powerful features such as repositories to store your reusable objects, flexible datatables for batch automation, and a Chrome extension which creates automation flows by recording your actions. For rapid prototyping, there's also an interactive live mode for trying out TagUI steps or JavaScript code in real-time. TagUI has built-in integration with Chrome / headless Chrome directly, which also works in live mode.

There is automatic waiting for web elements to appear + error-checking + nesting of JavaScript code blocks. Not forgetting the option to run automation flows hosted online or auto-upload run results online for sharing. TagUI also supports visual automation of website and desktop through built-in integration with Sikuli. Instead of using element identifiers, images can be used to identify user interface elements to interact with. TagUI has newly added integrations with R and Python for big data and machine learning capabilities. R and Python are popular languages with many frameworks and packages in this space.
