This post highlights the differences between FastThread Enterprise Edition and Public (free) Edition.


The primary reason why our customers buy Enterprise Edition is ‘security’. Thread dumps from production environment is considered as CONFIDENTIAL information in several enterprises. Thus, major enterprises do not want to transmit their confidential information on the internet and processed it on our servers.

ML Recommendations

 FastThread applies several heuristics and machine learning algorithms to detect various thread dump, memory-related problems. It also provides recommendations, JVM settings to address those problems. This problem detection capability and recommendation is available on Enterprise Edition and not on Public Edition. 

Unlimited Uploads

 In the public (free) edition, you cannot process more than 5 thread dumps/month. If you want to use the tool more frequently or use it extensively across all your portfolio of applications, public edition may not be the right choice.

Unlimited API Calls

As part of the CI/CD pipeline, several organizations do static code analysis using the tools like Coverity, SonarQube, Vera code, FindBugs…. Using FastThread, you can do runtime code analysis. FastThread provides REST API. This API returns JSON response, which contains key metrics related to your application’s memory utilization. You can invoke this API from CI/CD pipeline and see whether your code quality is improving or regressing between each code commit. You can make only 5 API calls/month in the public edition, whereas you make unlimited API calls in Enterprise Edition.

Unlimited Size

 In the public (free) edition, you cannot process more than 10 MB Thread dump files. This might be a tight restriction, given that dump file size can run for several Gigabytes. In Enterprise Edition there is no size restriction on the dump files that you can upload.

Report Sharing & Team collaboration

Sharing thread dump files amongst the team is a cumbersome process. Finding a proper location to store the dump file is the first challenge. The team member with whom you are sharing this report should have the thread dump analysis tool installed on his local machine. So that he can open the thread dump file with the tool you are sharing to see the analysis report. FastThread simplifies this process. It gives you a hyperlink like this. This hyperlink can be embedded in your emails, JIRA, and circulated amongst your team. When your team member clicks on this hyperlink, he can see the entire thread dump analysis report on his browser.

FastThread also lets you export the Thread dump as a PDF file. This PDF file can be circulated amongst your team members. This feature is supported only in Enterprise Edition.
