Hello @Megan_Justice ! Welcome to Seqera Community Forum 
Nextflow Tower has been archived and has not been maintained for several years. Its successor is Seqera Platform, which offers both a cloud-based version (SaaS) with free basic functionalities and paid tiers for additional features or on-premises deployment.
Seqera Platform functions as a control center for your workflows, similar to Nextflow Tower. You can run your pipelines on your own infrastructure, keeping your data fully under your control, while allowing Seqera Platform to monitor and coordinate pipeline orchestration as needed.
We offer a free Seqera Cloud Pro license for non-profit research and educational institutions. If you qualify and are interested, you can apply here.
