Deduptio vs DeDupe for Attio

Deduptio and DeDupe are the two tools built specifically to find and merge duplicate records in Attio. Neither is a generic CRM add-on with Attio bolted on — both connect directly to your workspace, scan for duplicates, and merge them. That makes the choice come down to how each one merges, what happens when a merge goes wrong, and what you pay as your workspace grows.

The short version: pick Deduptio if you want native Attio merges with activity history preserved, flat predictable pricing, and a free plan that performs real merges. Pick DeDupe if a 30-day rollback window or threshold-based auto-merging matters more to you than price.

How merging differs — and why it matters

Merging is where duplicate tools earn or lose your trust. Deduptio calls Attio's own merge under the hood, so the result is identical to merging by hand in the Attio UI: the surviving record keeps every email thread, call recording, note and activity entry, and references from other records keep pointing at it. There's no reconstruction step that can drop something.

DeDupe takes a different approach: it builds a "surviving record" by letting you pick the winning value for each conflicting field, then moves notes, tasks, files, lists and relationships across. That gives you fine-grained control over which value wins per attribute — genuinely useful when duplicates hold conflicting data — at the cost of a more involved review flow. Deduptio's per-attribute winner rules are on the roadmap; today Deduptio follows Attio's native merge semantics.

Safety: 24 hours vs 30 days

Both products understood the same thing: teams don't clean their CRM because they're afraid of breaking it. Deduptio snapshots every merge and gives you 24 hours to restore with one click — enough time to spot a bad merge in the daily workflow, and short enough that snapshots never hold stale data hostage. DeDupe advertises a 30-day rollback window, which is simply longer, and if a month-long safety net is a hard requirement, that's a real point in DeDupe's favor. In practice, bad merges surface within hours — the moment someone opens the record — but the difference is honest and worth stating.

Pricing: flat vs workspace-size tiers

Deduptio prices on a flat subscription: Free handles objects up to 10,000 records with 25 live merges a month, and Pro at $59/monthremoves the merge limit, adds fuzzy matching and covers objects up to 100,000 records. The price doesn't change as your workspace grows within those caps. See plans & limits.

DeDupe tiers its monitoring subscription by workspace record count — from $35/month at the smallest band to $123/month at 30,000 records and up from there (as of August 2026). A growing workspace moves you up tiers. Their $145 one-time cleanup is cheaper than Deduptio's $500 managed cleanup, but the two aren't the same product: DeDupe's is a self-serve run you review yourself, while Deduptio's managed cleanup is done for you, with match rules tuned to your data and a human reviewing every merge before it runs.

Which one should you pick?

Either way you'll end up with a cleaner workspace than running formulas over CSV exports. You can try Deduptio's free plan in about two minutes: connect your Attio workspace, run a scan, and review what it finds — the scan itself never changes any data.
