PIWI-interacting RNAs (piRNAs) and circular RNAs (circRNAs) are two kinds of non-coding RNAs (ncRNAs) which play important roles in epigenetic regulation, transcriptional regulation, post-transcriptional regulation of many biological processes. Although there exist various resources, it is still challenging to select such resources for specific research projects on ncRNAs. In this study, we create a novel portal named P4PC which is a repository of databases and computational tools for facilitating ncRNA research. Specifically, 249 computational tools, 126 databases and 420 papers are manually curated in P4PC. All entries in P4PC are classified in 5 groups and 26 subgroups. The list of resources summary is provided in the first page of each group. According their research proposes, filter rank and search servers are provided to uses. Users can quickly select proper resources for their research projects by viewing detail information and comments in P4PC. P4PC is launched on July 10, 2023 and will be regularly updated.
