Top 11 Free Trial & Open Source Process Mining Tools in 2024

Process mining is a cutting edge technology that applies data science and algorithms to automatically discover, monitor and improve real processes by extracting insights from event log data. With process mining, companies can gain transparency into how work is actually getting done, identify bottlenecks and inefficiencies, ensure compliance, and make data-driven decisions to optimize processes. The global process mining market size is expected to grow from USD 324 million in 2019 to USD 1,409 million by 2024, at a Compound Annual Growth Rate (CAGR) of 34% during the forecast period according to MarketsandMarkets. This growth is fueled by the need to improve process efficiency and compliance, with over 60% of organizations planning to invest in process mining as per Deloitte.

While large enterprises have been early adopters, small and medium businesses can also benefit tremendously from applying process mining. But many are deterred by the high cost of commercial tools. This is where open source and free trials come in – they allow you to get started with process mining at little to no cost. In this comprehensive guide, we provide an overview of the top free and open source process mining tools available in 2024 to help you find the right solution for analyzing, visualizing and optimizing your business processes.

How can process mining help your business?

Before we dive into the tools, let‘s briefly look at why process mining is so valuable:

  • Discover processes automatically – Process mining eliminates the need for manually mapping processes. The algorithms automatically model processes based on historic event log data.
  • Identify bottlenecks and waste – Process mining provides insights into delays, service degradation, loops and other bottlenecks. This allows targeting root causes.
  • Monitor process performance – Ongoing monitoring helps assess if KPIs are being met and processes improved.
  • Improve compliance – Any deviations from optimal processes are flagged immediately so compliance issues can be addressed.
  • Support process redesign – By understanding actual processes, you can redesign them for maximum efficiency. Changes can also be monitored.
  • Enhance customer experience – Customer-focused metrics can be optimized by identifying and fixing issues that impact customer journeys.

Clearly, data-driven process insights can transform efficiency, productivity, compliance and customer experience. But where do you start? Let‘s now explore the top open source and free process mining tools available.

How to choose between open source and free trials?

Here are some guidelines on when open source or free trials may be more suitable:

  • For basic process discovery and occasional analysis, open source tools like Disco, Apromore or ProM Lite provide good free options.
  • For small teams that need collaborative process modeling or workflow management, the free version of Process Street is a simple option.
  • For enterprises that handle large data volumes or have complex processes, a robust commercial tool like Celonis or IBM on a free trial basis is preferable.
  • To minimize costs, using an open source tool like Disco for initial process exploration and then upgrading to a commercial tool like Minit for advanced use cases can be a cost-effective approach.
  • For long term use, free trials allow you to validate commercial tools with real data from your organization before purchasing. Open source works if you have in-house expertise.
  • For process enhancement or automation, commercial tools have more built-in capabilities though open source allows customization.

So in summary, open source offers flexibility and customization while free trials enable evaluating robust enterprise-grade process mining tools. Consider your budget, size, needs and time frame before deciding.
