DupeCatcher focuses on Salesforce duplicate prevention at the point of entry.

It runs in Salesforce Classic and Lightning, supports several Salesforce editions, and is available as a free native AppExchange app on Android, iOS, and the web.

An alternative may fit better if you need capabilities DupeCatcher does not provide. DupeCatcher does not clean existing records, support mass imports, automatically merge records, or retain blocked records for later review. Consider whether you need cross-system entity resolution, bulk or scheduled merging, broader data formats, machine-learning methods, APIs, self-hosting, or a HubSpot-native workflow. Also weigh each product's platform coverage, price, setup model, record limits, and review controls before switching.
