	$bootstrap = Bootstrap::create(BP, $_SERVER);

	$obj = $bootstrap->getObjectManager();

	$state = $obj->get(Magento\Framework\App\State::class);

	$ruleFactory = $obj->create(\Magento\CatalogRule\Model\RuleFactory::class);
	$catalogRuleRepository = $obj->create(\Magento\CatalogRule\Api\CatalogRuleRepositoryInterface::class);

	$rule = $ruleFactory->create();

	$rule->setName('Programmatic Rule')
	   ->setDescription('Created Programmatically Object Manager')
	   ->setIsActive(1)
	   ->setCustomerGroupIds([0, 1, 2, 3]) // Assuming these groups exist
	   ->setWebsiteIds([1]) // Assuming this website exists
	   ->setSimpleAction('by_percent')
	   ->setDiscountAmount(10)
	   ->setStopRulesProcessing(0);

	// Define conditions here
	$conditions = [
	  'type' => \Magento\CatalogRule\Model\Rule\Condition\Combine::class,
	  'aggregator' => 'all',
	  'value' => 1, // 1 means TRUE, i.e., ALL conditions have to be TRUE.
	  'new_child' => '',
	  'conditions' => [
	     [
	      'type' => \Magento\CatalogRule\Model\Rule\Condition\Product::class,
	      'attribute' => 'category_ids',
	      'operator' => '==',
	      'value' => '10' // Category ID to which the rule applies
	     ]
	   ]
	];
