### What does SpiderFoot.tools do?
SpiderFoot.tools provides browser-based OSINT workflows for researching usernames, email addresses, and IP addresses using publicly available information.
Username searches can check a large catalog of public websites and account categories, while additional web-search context helps identify relevant public references. Email and IP tools provide corresponding public-source and network-related intelligence.
The service is designed to make common OSINT checks accessible from a web browser without requiring users to install or configure the SpiderFoot open-source software.
**The lowdown:** It’s a broad OSINT automation and correlation platform designed to reduce the amount of manual searching required during an investigation.
### How to Use:
**1. Enter a username, email address, or IP address you are authorised to investigate.**
**2. Start the scan and wait for the available public-source checks to complete. Review the returned matches, source URLs, web-search context, and scan activity.**
**3. Open the original sources and independently verify relevant findings.**
Note: Treat matches as investigative leads rather than proof of identity, ownership, intent, or wrongdoing.

### Cookies:
The site uses Google Analytics cookies (\_ga and \_ga\_WMG0MQ892B) for usage measurement, Google consent/advertising cookies (FCCDCF, FCNEC, \_\_gpi and **mggpc**), and a first-party osinttools\_user\_id cookie used by the site's application.
### Use in Reporting
SpiderFoot.tools can be useful for:
* Investigating usernames and identifying publicly available accounts or online references associated with them.
* Investigating email addresses and identifying publicly available services, accounts, breaches or other references connected to them.
* Investigating IP addresses and identifying associated domains, hosts, services and other publicly available infrastructure information.
* Correlating username, email and IP findings to identify connections requiring further investigation.
* Generating investigative leads from information collected across multiple OSINT sources.
* Supporting identity, digital-footprint and infrastructure research in investigative reporting.
* Building a broader picture around a username, email address or IP address before conducting further manual verification.
A practical use case is an organisation performing an authorised review of its own digital footprint: a security team can search known company usernames or email addresses, review returned public references, verify relevant findings at the original source, and document confirmed exposure for remediation.

| Supports username, email and IP research from one web interface. | A matching username does not prove that two accounts belong to the same person. |
| Enables look up of IPv4 and IPv6 network information. | Results can contain false positives, false negatives, stale profiles or ambiguous matches. |
| Return IP context including ASN, autonomous-system name, organisation and location labels where available. | Public platforms may block automated requests, rate-limit checks, require authentication or change their page structure. |
| Results show source/status information for review and follow-up. | Email results indicate account/public-source context and do not prove mailbox ownership, current control or deliverability. |
| Presents results through a browser without requiring a local SpiderFoot installation. | IP geolocation is approximate and must not be interpreted as a precise physical address. |
|
| Coverage depends on third-party services and public-source availability and can change without notice. |
### Summary
SpiderFoot.tools is best used during the discovery, triage, and verification stages of an OSINT investigation. Analysts can use it to identify possible public accounts associated with a username, discover public references connected with an email address, or obtain network context for an IP address.
**Important Note:** Returned results should be treated as investigative leads rather than standalone evidence. Before including a finding in a report, analysts should open the original source, record the source URL and date, verify that the information still exists, and independently establish any claimed connection to the subject.
### Ownership
SpiderFoot.tools is an independently owned and operated third-party OSINT web service. It is not affiliated with, endorsed by, or operated by the SpiderFoot open-source project or its maintainers.
SpiderFoot.tools maintains its own browser-based workflows, website, methodology, privacy documentation and research content independently.
The service's public website does not currently identify a separate corporate entity or geographic headquarters.
### Ethical Considerations
• Only investigate identifiers where there is a lawful and legitimate purpose for doing so.
• Obtain authorisation where required, particularly for organisational security assessments or investigations involving other individuals.
• Treat public availability as an access condition, not automatic permission for unrestricted collection, profiling or publication.
• Minimise collection and avoid submitting unnecessary sensitive personal information.
• Do not treat a matching username or email signal as proof of identity or account ownership.
• Independently verify material findings before attributing them to a person or organization.
• Consider the potential privacy and safety impact before including personal information in a report.
• Avoid publishing data that is not necessary to support the investigative conclusion.
• Respect applicable laws, source terms, organisational policies and access controls.
• Do not use the service to bypass authentication, obtain credentials, harass individuals or access private information.
• Preserve uncertainty in reporting where attribution remains ambiguous.
• Stop or narrow the investigation if the collection becomes disproportionate to the original research purpose.
