Core capabilities

Three focused ways to investigate a public footprint.

Choose a target type, run the sources that apply, and review structured evidence without juggling multiple interfaces.

Lookup 01

Username discovery

Check public profile patterns across a broad source list, then review likely matches with source context.

Lookup 02

Email exposure search

Review public account signals and exposure indicators with grouped results and transparent scan progress.

Lookup 03

IP intelligence

Understand geolocation, ASN, organization, and routing context through Cloudflare-powered intelligence.

About the workspace

OSINT should produce leads you can understand and verify.

SpiderFoot.app brings a small set of useful public-source investigations into one consistent interface. It is designed to help researchers move from a target to reviewable evidence without hiding uncertainty.

How SpiderFoot.app works

Focused workflow

Start with one identifier and keep source results, progress, and follow-up context together.

Responsible use

Use the service only for lawful, authorized research and verify significant findings independently.

Independent, open-source inspired

SpiderFoot.app is an independent browser service. It is not the official SpiderFoot project, SpiderFoot HX, or an Intel 471 product.
