What is the best free Salesforce deduplication tool?

Salesforce's native Duplicate Rules are free and can prevent new duplicates from being created. However, they won't find or merge existing duplicates. Most AppExchange tools offer free trials so you can test with your real data before purchasing. No Duplicates is completely free on sandboxes with no restrictions.

Can Salesforce automatically merge duplicates?

Not natively. Salesforce can flag potential duplicates via Matching Rules and block creation via Duplicate Rules, but it cannot auto-merge. AppExchange tools like No Duplicates and Cloudingo add auto-merge capabilities with configurable strategies for choosing master records and field values.

How do I run a duplicate check in Salesforce?

For a basic duplicate check, go to Setup, then Duplicate Management and configure Matching Rules and Duplicate Rules. For more advanced detection including fuzzy matching, cross-object matching, and scheduled scans, install an AppExchange deduplication tool.

What's the difference between duplicate detection and duplicate prevention?

Detection finds existing duplicates in your database (reactive). Prevention blocks new duplicates from being created (proactive). Best practice is to use both: Salesforce's native Duplicate Rules for prevention, and an AppExchange tool for detection and merging.

What does native vs non-native mean for AppExchange apps?

A native app runs entirely on the Salesforce platform and your data never leaves Salesforce's servers. A non-native app sends data to external servers for processing. If your organization has strict data residency or compliance requirements (HIPAA, GDPR, SOC 2), native apps eliminate that risk entirely.

No Duplicates vs Cloudingo — which should I choose?

It depends on two factors: data security and budget. No Duplicates is 100% native (data stays in Salesforce), includes all features from $240/year with unlimited users, and offers 22+ auto-merge strategies with Flow support. Cloudingo is non-native, starts at $2,500/year for one user, and its key differentiator — undo merge — requires the $6,000/year Professional plan.

What is the cheapest Salesforce deduplication tool?

Among the tools reviewed here, No Duplicates has the lowest starting price at $240/year with all features included and unlimited users. Cloudingo starts at $2,500/year, DemandTools at $11/month per Salesforce license, and Plauti uses custom pricing.

Are non-native Salesforce apps safe to use?

Non-native apps process your CRM data on external servers outside Salesforce's security boundary. This introduces additional considerations for data residency, compliance (HIPAA, GDPR, SOC 2), and vendor security practices. Many organizations use non-native apps successfully, but if your security policy requires data to remain within Salesforce, choose a 100% native app.

Best Salesforce Deduplication Tools in 2026 [Compared]

Duplicate records are one of the most persistent data quality problems in Salesforce. They waste sales reps' time, skew reports, and create a poor customer experience. According to Gartner research, bad data costs organizations an average of $12.9 million per year — and duplicates are a major contributor.

Salesforce offers native Duplicate Rules, but they only prevent new duplicates from being created. They don't help you find and merge the thousands of duplicates already sitting in your CRM. For a deeper look at these limitations, see our post on why Salesforce duplicate management is not enough. A basic duplicate check using standard reports can surface some issues, but it won't scale — and it won't resolve them. That's where AppExchange deduplication tools come in.

We evaluated four of the most popular Salesforce deduplication tools available in 2026. They vary significantly in pricing, data security architecture, and feature depth. Here's what we found.
