AbuseIPDB alternative: how isipsafe compares

isipsafe and AbuseIPDB both collect abuse reports and score IP addresses from 0 to 100. AbuseIPDB is older and receives more reports. isipsafe gives you more on a free account, including use on company systems, with no ads.

We run isipsafe, so we are not neutral. To keep this checkable, the AbuseIPDB details below come from its own public pages, read on 2 November 2026.

The short answer

isipsafe may suit you if

  • You protect company or client systems and want to do it on a free account.
  • You want more free lookups, or wider network checks, without paying.
  • You want the whole blacklist at the score you choose, with country filters, on a free account.
  • You want firewall-ready downloads such as ipset, nftables, nginx or MikroTik.
  • You want your AI assistant to work with the service directly. Our MCP server is built in and in production, with nothing to install, and an assistant can report attacks and fetch the blacklist as well as look addresses up.
  • You prefer a site with no ads and no requests for donations.

AbuseIPDB may suit you if

  • Report volume and a longer history matter most to you.
  • You want a self-serve paid plan with a public price.
  • You need usage type data or a connector built for your product.

Wrong listings You can withdraw your own reports. For other people's reports, use the contact form and a person reviews the request. You can delete your own reports. For other people's reports, its API docs point to a takedown form.

If you decide to switch

/api/v2 takes AbuseIPDB's paths, parameters and Key header, so most scripts need a new base URL and a new key:

https://api.abuseipdb.com/api/v2  →  https://isipsafe.com/api/v2

Check three differences first: the blacklist defaults to a score of 75 rather than 100, usageType is always null, and scores differ between the services because they come from different reports. The switching guide has the details.
