Here we introduce the ALMA CO-CAVITY project, the first interferome tric CO(1-0) survey of a large sample of 41 void galaxies (VGs) to characterise in detail their molecular gas properties. It is built over the CAVITY proje ct, offering optical integral field unit (IFU) data, enabling a direct, pixel-to-pixel comparison between molecular gas (from ALMA), star formation, and stellar properties, as well as the derivation of their scaling relations. In this work we present ALMA data products for our sample, containing data cubes, moment maps and position-velocity diagrams at angular resolutions of 1 arcsec. We also present molecular gas, stellar mass, and star formation rate surface density maps at a common resolution of 2.5 arcsec. We contextualise our sample against representative unresolved and resolved surveys. While our sample provides a good representation of the VG population and follows the distribution of key properties seen in star-forming galaxy samples, galaxies included in resolved studies from the literature tend to be more massive, less isolated, and located in denser large-scale environments. We present global scaling relat ions for the ALMA CO-CAVITY sample and find that the molecular gas main sequence exhibits the smallest scatter (0.21 dex), followed by the Schmidt-Kennicutt relation and the star-forming main sequence. From integrated properties alone, we find that these scaling relations for VGs are compatible with those for denser environments. This paper lays the foundation for forthcoming studies exploiting this unique dataset.2026A&A...712A.227Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/712/A227CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/692/A125 : Molecular gas in void galaxies (Rodriguez+, 2024)J/A+A/578/A110 : Isolated galaxies, pairs and tripletsJ/MNRAS/476/3661 : Morphology of SDSS galaxies (Dominguez Sanchez+, 2018)J/MNRAS/415/1188 : Galaxies in the Lynx-Cancer void (Pustilnik+, 2011)J/ApJ/903/145 : ALMaQUEST.
