We are building the reliability infrastructure for the internet.
Our tools give people the ability to identify signals they can use to determine the credibility of the information they consume. Our first goal is to help Wikipedia editors evaluate reference reliabilty.
- WikiSignals.org: Searchable database of 70K websites with domain data and credibility indicators.
- Editing Tools: Recommendations from active Wikipedia editors (from our ongoing series of editor interviews).
- WikCred World: Lists of projects, services, APIs, and resources.
- MisinfoCon: (post) WikiSignals: Strengthening the Credibility of Wikipedia Citations.
WikiSignals is a proposed credibility-related Wikipedia Editing Tool.
Determining the reliability of a source could be easier if data to help with that determination was more accessible. WikiSignals compiles a range of available data so Wikipedians can better evaluate source credibility.
The project grew out of WikiCredCon 2025. It's a collaboration between Veri.FYI, Factiverse, SimPPL, AfroCrowd, Iffy.news, and the Internet Archive Reference Explorer: organizations pioneering efforts to improve access to source-credibility information.

Overview
Wikipedia's core mission is to be a source of credible information. This requires maintaining the credibility of not only internal articles but also external references. Wikipedia has a Perennial Sources list that ranks sources by their reliability. However, this list is only available for a handful of languages. The Wikipedia English is the most developed and even that has ranks for only a few hundred websites (out of countless millions).
WikiSignals aims to close this gap. Participants in the WikiCred initiative are developing a Wikipedia editing tool that automates editor tasks related to credibility. The tool provides reliability-related signals for sources being considered for citations, references, and external-link lists. It returns website domain-level data[1] as well, including global traffic rank, registration date, and social media usage statistics — information that can be used to judge the quality of the reference.
The WikiSignals tool can expand to assist with other editing tasks. We plan to interview Wikipedia editors to find and address problems that WikiSignals might address, particularly with respect to the user workflow of editing. Our broader goal is to become part of an effort to build a comprehensive reference dataset of credibility indicators for news outlets, science journals, and possibly other source types.
