What Dedupely is
Dedupely is a CRM-connected deduplication app: you grant it access to HubSpot (its main home) or another supported CRM, it scans records, shows likely duplicate pairs, and merges them inside the CRM with rules for which fields survive. Pricing is a subscription based on how many records your CRM holds, as of mid-2026. For a team living in HubSpot that wants one-click merging and is comfortable with a third-party integration holding CRM access, that is a genuinely convenient shape.
Where the approaches split
The trade is access for convenience. A connected app can merge in place, but it holds an OAuth grant to your entire contact database, and its servers process your records. Dedupe.dev's answer is to never connect: the contact workflow is export, clean locally, re-import. Slower by a few clicks, but no third party touches the CRM, and the browser half sends nothing anywhere, which you can verify in DevTools. The second trade is merge versus remove. Dedupely merges field-by-field; we only drop duplicate rows and keep the first occurrence, because a wrong automated merge loses data invisibly. If you need surviving-field logic, do it in the CRM on the short list that remains.
How Dedupe.dev works, for contrast
Two halves. The browser tools are free and unmetered: your file is parsed and deduplicated by JavaScript in the tab, nothing is uploaded, and you can watch the empty Network panel while it runs. The HTTP API is for automation: exact or fuzzy matching, metered in rows (1,000 a month free with a key, 100,000 on Starter at $19/mo, 300,000 on Pro at $49/mo), with fuzzy requests up to 50,000 rows each. Duplicates are removed, never merged: the first occurrence survives, and re-importing the cleaned file is your step.
FAQ
Frequently asked questions
Which should I pick for HubSpot?
If you want duplicates merged inside HubSpot with field-level control and you are comfortable granting a third-party app CRM access, a CRM-connected tool like Dedupely is built for exactly that. If you would rather nothing touch your CRM, export to CSV, dedupe locally in your browser, and re-import with update-existing, which is the workflow our guides document.
Does Dedupe.dev merge records like Dedupely does?
No, deliberately. We only remove rows; the first occurrence is kept intact. Merging two records into one is CRM-side logic (which field wins?) and doing it wrong silently loses data, so we leave merging to the CRM after the row count is small enough to review.
What does each cost?
Dedupely prices by CRM record count on a monthly subscription (check their site for current tiers). Dedupe.dev's browser tools are free without an account; the API meters rows, with 1,000 a month free and paid plans at $19 and $49 a month.
