Neotys Labs

Neotys provides APIs and extensions to customize and extend the behavior of NeoLoad. Neotys Labs provides different pluggable assets for NeoLoad. The different asset types are:

Maturity levels

Published assets may have different levels of maturity:

  • Experimental: experimental work that has not gone through Neotys’ quality assurance process and likely does not meet Neotys quality standards.
  • Beta: assets, which have received some QA testing but did not go through the full qualification process.
  • Stable: went through the full quality assurance process once.


Neotys does not provide support for these downloadable assets; they are not Neotys’ products. The assets listed here are intended to be used by experts and may require some coding ability. Note some assets may be removed from this page without notice for various reasons. These include, but are not limited to, plans to incorporate into NeoLoad or the asset proved to have limited use. Discontinued assets may be used in future versions of NeoLoad, even if they have been removed from Neotys Labs.


A specific NeoLoad edition and/or option may be required to use these assets. Refer to the NeoLoad requirement for each asset. Feel free to contact for a trial license if you want to evaluate an asset.
