Open Source RPA – The new face of innovation and the next evolutionary step in RPA | IA – Part 3 of 6

The sign of a maturing market can often be judged by the amount of innovation happening within an industry or sector and Open Source RPA is no different. In Part 1 we introduced Open Source RPA. In part 2 we looked a variety of Open Source RPA platform providers and today we continue that trend and look at TagUI, RPA for Python, Robin and OpenBots.

TagUI plus picture

A command-line tool that enables digital process automation. Maintained by AI Singapore, this government-funded application helps in the creation of local artificial intelligence capabilities.

TagUI’s Ken Soh has been quoted as saying that TagUI, an Open Source tool maintained by the government funded initiative AI Singapore is a Command Line Interface and it is suitable for 

  • OCR (built-in)
  • UI automation
  • Desktop Applications
  • Web Applications
  • Direct ML model Integration (with API / R code / Python)

Top Features

  • Easy to use interface and natural language like-syntax feature eliminates the need for coding knowledge
  • Promotes the visual automation of websites and desktops
  • You can use TagUI to write in over 20 human languages as well as JavaScript e.g. English, Chinese, Japanese.
  • It offers the option of extension for recording web action
  • Automates Chrome in both visible and invisible modes.
  • Can integrate it with Python and R integration for big data, AI, and ML.

Top 5 Features

  1. OpenBots Studio (Open Source Developer Tool for building Simple to Complex Automations)
  2. OpenBots Server (Open Source Orchestrator for managing unlimited Bots)
  3. OpenBots Discovery (A SAAS based OpenBots Process Discovery and Analysis tool)
  4. OpenBots Documents (A SAAS based Intelligent Document Processing tool)
  5. OpenBots Academy (Free Online training Academy with multiple courses)

Robin (now part of Microsoft)

The final tool in todays list of Open Source RPA tools is Robin. Robin is a free open source and effective programming language used for building RPA software bots.
