{
    $storeManager = \Magento\Framework\App\ObjectManager::getInstance()->create(
         '\Magento\Store\Model\StoreManagerInterface'
    );
    $catalogRule = \Magento\Framework\App\ObjectManager::getInstance()->create(
         '\Magento\CatalogRule\Model\RuleFactory'
    );
    
    $websiteId = $storeManager->getStore()->getWebsiteId();//current Website Id

    $resultProductIds = [];
    $catalogRuleCollection = $catalogRule->create()->getCollection();
    $catalogRuleCollection->addIsActiveFilter(1);//filter for active rules only
    foreach ($catalogRuleCollection as $catalogRule) {
        $productIdsAccToRule = $catalogRule->getMatchingProductIds();
        foreach ($productIdsAccToRule as $productId => $ruleProductArray) {
            if (!empty($ruleProductArray[$websiteId])) {
                $resultProductIds[$productId] = $catalogRule->getName();//name of rule
            }
        }
