Panoramax is a project to collect and display street-level imagery. The project is implemented as free/open source software and allows the crowdsourcing of images, which are then openly licensed. The project was started in 2022 by the French National Geographic Institute (Institut national de l'information géographique et forestière, IGN) and the French OpenStreetMap (OSM) chapter. It was designed and developed by a state-owned start-up and is updated and maintained by a community of volunteers and IGN staff. As a free & open source alternative to Google Street View, Panoramax is a federated system that allows individuals and organizations to host their own instances for image hosting.

In 2021, the IGN launched a consultation on "geocommons". Initially, the project was designed to respond to the problems encountered by local authorities and other French stakeholders.

OpenStreetMap France responded to this consultation, proposing the creation of an open database for street-level images.

In April 2022, the IGN launched their call for participation for three "geocommons" including the proposal of OSM France. In October 2022, Panoramax was launched as part of the "Geocommons Factory".

In June 2024, Panoramax won a grant by the NLNet Foundation as part of the NGI0 Commons Fund, which is supported by the European Commission as part of the Next Generation Internet program. In the same year, the project also gained more media attention, especially in public and private French-speaking media, including Franceinfo, France Bleu, Europe 1 and ZDNet.

In October 2025, 6 Panoramax instances were online, beyond the initial ones by IGN & OSM France, this included instances for Taiwan and Wales.

The name "Panoramax" was decided after a proposal phase and vote by 48 community members.

The project's budget is €500,000, and 6 people work on the project.
