DupeCatcher

DupeCatcher is a Salesforce app for stopping duplicate records as they are entered. It is best for Salesforce teams that want customizable, in-the-moment checks across common record types. Its free plan includes every feature, but it does not resolve duplicates already in the database.

Overview

Installed in a Salesforce organization from AppExchange, DupeCatcher applies duplicate checks at the point of entry. That makes it a focused prevention tool: useful for keeping new records from adding to a problem, but not a cleanup utility for an existing backlog.

The managed package receives automatic upgrades. The app works with Salesforce Classic and Lightning, and supports Professional, Enterprise, Unlimited, and mobile editions.

Key features

Teams can build filters and matching rules from standard or custom Salesforce fields, using different matching styles. This flexibility lets organizations define what counts as a duplicate for their own data; in practice, the safeguards are only as useful as the rules they configure.

Rules can block duplicate inserts or alert users, and users can override a block when a record should be created. This balance is valuable where prevention matters but legitimate exceptions still occur. Coverage includes leads, contacts, accounts, and person accounts, with leads checked against contacts and accounts as well.

A background mode can collect duplicate data for analysis before rules are rolled out, helping teams assess a proposed setup before users encounter it. There is an important limitation: blocked records are not retained for later review. The filter summary shows only a raw count of blocked duplicates.

DupeCatcher does not clean existing records or support mass imports. It also does not automatically merge records, so organizations seeking bulk remediation or a merge-centered cleanup process will need another tool.

Pricing

The Free plan costs nothing, with payment never required, and includes all DupeCatcher features. There is no separate trial to weigh; the product is offered as a free plan. With no paid tier or feature-based upgrade, it is an unusually straightforward fit for teams whose needs are limited to real-time Salesforce checks. The free offer does not change the product's narrow scope: it will not clean existing records or process mass imports.

Platforms

DupeCatcher is listed for Android, iOS, and web. Within Salesforce, it works in Classic and Lightning and is installed as a native app from AppExchange.

Who it's for

Choose DupeCatcher if your organization wants to prevent or flag new duplicates in Salesforce, needs rules based on its own fields, and can accept that blocked attempts are not available for later review. It is a poor fit for teams whose immediate priority is merging, bulk import checks, or clearing an existing duplicate backlog.

Pros and cons

• Pros: Every feature is included in the free plan, so teams can use customizable matching and prevention without a paid-tier decision.
• Pros: Blocking, alerts, and user overrides support prevention while allowing legitimate exceptions.
• Pros: It spans leads, contacts, accounts, and person accounts, including lead comparisons against contacts and accounts.
• Cons: It cannot clean existing records or check mass imports, limiting its value for database remediation.
• Cons: Blocked records are not saved for later inspection; users get a raw count rather than a review queue.
• Cons: It does not automatically merge records.

Alternatives

• Tilores is worth considering if you want a freemium option with a local mode that allows up to 100,000 records per deployment without an account or licence key.
• AWS Entity Resolution may suit provider-matching workflows; its data service provider matching plan is billed per 1,000 records processed and requires a provider license or subscription, with provider costs additional.
• Entify offers an open-source route, but its early project has a default 100 MB upload cap and holds one resolution result in memory at a time.
• Koalify is an alternative for sandbox or demo accounts and portals below 10K records, which qualify for its free plan.
• Plauti Deduplicate has a free Salesforce AppExchange version; full-edition features require a trial or custom pricing.
• pyJedAI is a free Linux, self-hosted, and Windows option identified as a research project by the AI-Team at the University of Athens.
• Python Record Linkage Toolkit is a free, self-hosted option aimed at research use and small or medium-sized files.
• Splink is free software distributed as a Python package under the MIT license.

Verdict

DupeCatcher is a strong fit for Salesforce organizations that want configurable, real-time duplicate prevention at no cost. Its main advantage is that the complete feature set is free; look elsewhere if you need to clean existing data, validate mass imports, merge records, or review blocked attempts individually.
