Discovery is a macOS utility for browsing Bonjour and DNS-SD services on your local network and viewing the details they advertise.
What is Discovery?
Discovery is a network utility for macOS that helps users browse Bonjour and DNS-SD services available on a local network or in wide-area Bonjour domains. It is designed for people who need to see which devices and services are being advertised, such as printers, media servers, development tools, and other network-enabled apps. The app presents discovered services in a readable list and lets you inspect details such as service type, host information, addresses, and TXT records. This makes it useful for troubleshooting service discovery problems, checking whether a device is visible on the network, or exploring what zero-configuration services are currently available. Discovery is published by Tildesoft and is distributed through the Mac App Store for modern versions of macOS.

Safety overview
Status: Safe
Discovery is a legitimate network utility for viewing Bonjour service announcements on your network. Access to local network information is normal for this type of app because it needs to discover and display nearby services. It is not a system component, so removing it only affects your ability to browse these network advertisements in the app. As with any network tool, use it on networks you trust if you prefer to limit what nearby devices and services are visible to the app.
Recommendation: Keep Discovery if you use it to troubleshoot or inspect Bonjour services on your Mac or network. If you do not use network discovery tools, you can remove it without affecting macOS itself.
