United States – October 12, 2026 -- Sylabs will end-of-life SingularityPRO, Singularity Enterprise and SingularityCE on October 25, 2026, the date its engineering work on the SingularityCE project and Singularity ecosystem stops. CIQ, which backs the competing Apptainer project, says it is already moving to absorb Singularity's user base.
Sylabs releases formerly commercial features as open source
Sylabs is closing out SingularityPRO and Singularity Enterprise by open-sourcing functionality previously reserved for those paid offerings. CIQ expects the Apptainer community to pick up and maintain those features.
Singularity's 2015 HPC origins lead to a split in 2021
Gregory Kurtzer started Singularity at Lawrence Berkeley National Laboratory in 2015 for multi-user HPC clusters, where Docker's security model did not fit. He founded Sylabs in 2017 to develop it commercially.
