End of Life (EOL) Announcement

Per Section 2.24 “End of Life” and Section 11 “Termination” of Sylabs’s EULA, Sylabs, Inc., (the “Company”) has decided to discontinue SingularityPRO, Singularity Enterprise, and SingularityCE (collectively, the “Software”) as of October 25, 2026. PRO will be merged with CE and a final open-source CE 4.6 release will be made that includes:

  • The functionality of the PRO logging plugin
  • The functionality of the PRO Enterprise management plugin
  • “Trusted bind paths” functionality
  • “Native hooks” functionality

End of Engineering Announcement (the EOE)

In conjunction with the EOL Announcement, the Company is also announcing the EOE, which means the Company will cease engineering related to the Software and will cease providing engineering support as of October 25, 2026. Users may continue to use SingularityCE under the terms of their open-source licenses at their own risk.

Streamlining Workflows Innovating Security:

The Sylabs Advantage

Software containers have quickly grown in popularity in recent years for their ability to provide consistency across different environments, simplify deployment, enable scalability, isolate applications, and maximize resource efficiency.

Sylabs has a proven track record for using containers to solve big workflow and security challenges in performance-intensive and mission-critical environments. Singularity, our widely adopted container runtime, was specifically developed to support mobility of compute. It implements a unique security model through the Singularity Image Format (SIF) to mitigate privilege escalation risks and provides a platform to capture a complete application environment into a single Open Container Initiative (OCI) compliant file.

What Singularity Users Say

“By using SingularityPRO, we will be able to facilitate Fugaku to be a secure, reproducible and portable high-performance computing environment for a wide spectrum of users spanning academia to industry.”
Satoshi Matsuoka

Director of RIKEN Center for Computational Science (R-CCS)

“As an early adopter of Singularity, the San Diego Supercomputer Center (SDSC) has been collaborating with Sylabs and the development team for several years. The scientific community is developing software at an unprecedented rate, and our collaboration with Sylabs helps us more quickly respond to the evolving needs of our users.”
Mahidhar Tatineni

User Support Group Lead at San Diego Supercomputer Center

“The availability of ready-to-use binary distributions is the primary benefit we’ve derived from SingularityPRO. This has made it much easier for our systems configuration staff to provision SingularityPRO onto servers and compute nodes."
Oleksandr Moskalenko

Research Computing Applications and Facilitation Lead, University of Florida

“When we first adopted Singularity a few years ago, the driving case was to support TensorFlow on our cluster with GPUs and an old operating system. It was relatively easy to build a container with the right libraries and environment using Singularity. The use cases today are increasing even as we update our clusters, so Singularity is more than a transient solution.”
Chris Reidy

Research Facilitation Manager, University of Arizona

“Reproducibility is especially important to ensure scientific integrity and accuracy, making Singularity containers incredibly valuable because they can be shared so seamlessly. Along with many other bioinformatics researchers (too many to name), we are helping set a new standard for scientific discovery with our commitment to ensuring our studies are entirely reproducible with Singularity containers from Sylabs.”
Mark T. W. Ebbert, Ph.D

Assistant Professor Sanders-Brown Center, University of Kentucky

“As our advanced simulation codes push the boundaries towards more specialized hardware and systems, the need for performance portability and adaptability grows in HPC. It's about ensuring our software doesn't just run, but runs efficiently and consistently, regardless of the underlying system. SingularityCE 4.0 addresses this vision in an open-source context, offering interoperable OCI support and facilitating adaptable and efficient containerized application deployments. Amidst the complexities of large-scale computing environments, teams thrive when collaboration is seamless; SingularityCE 4.0 takes a commendable step in facilitating the power of teamwork."
