About OpenGroupMap

Collaborative maps for groups

OpenGroupMap is a collaborative mapping platform: it lets a group create a controlled map and open it up for participation. The owner stays in charge of the map, while anyone they invite — or anyone with the link — can add the locations they know about. No account is needed to contribute.

It started as a way for WhatsApp groups, communities, and events to answer one simple question — “where is everyone?” — without spreadsheets, logins, or fuss.

Who it's for

Groups & communities

Friend groups, clubs, alumni networks, and villages mapping where people and resources are — together, in one place.

Organisers & projects

Event planners, civic projects, and conservation efforts collecting location data from many contributors without managing accounts.

Teams that need control

Owners who want open contributions but still decide what stays public, link-only, or private.

The idea

Controlled, but open

The owner curates; the crowd contributes. You get the reach of open participation with the order of a single, maintained map.

No barriers to contribute

Contributors don't need an account. Share one link and people can add what they know — that's where the best local knowledge comes from.

Yours to keep private or share

Make a map public, share it link-only, keep it private, or password-protect it. You decide who sees what.
