Callejear is a Spanish directory and exploration platform designed to help people understand and compare places, from municipalities to individual streets. Its coverage includes all 8,132 Spanish municipalities and a catalogue of more than 730,000 streets. Visitors can search by province, municipality or street, explore locations on a map, and open street profiles with information about the surrounding area. Search filters help users find streets by estimated walkability and the recorded proximity of parks, schools and pharmacies. Callejear also offers municipal data on population, housing, employment and income, alongside tools covering topics such as fibre broadband availability, flood exposure and solar orientation.

The platform combines public information from sources including Spain’s National Statistics Institute, Catastro, SEPE and AEAT with collaborative OpenStreetMap data. Each profile provides context about its sources and coverage. Callejear notes that data coverage can vary, information may not be current in real time, and missing listings do not mean a service is absent.
