About

Porthole NVR

Read full description

Porthole is a native iPhone and iPad client for Frigate—the open-source NVR you run yourself. Built by a small business for the self-hosting and Frigate community: connect to your own server, watch go2rtc WebRTC streams, and keep video between your device and your installation. There is no Hallway Trails account and no cloud relay. FEATURES (NOW) • Live camera grid with tap-to-open detail view • Landscape fullscreen for wide cameras • Works with authenticated or unauthenticated Frigate setups • Passwords stored in the iOS Keychain on your device • Reorder cameras to match how you actually use them • Local network support for home LAN servers COMING NEXT We’re bringing more of the Frigate web experience into a native app—supported by ads and optional Pro: • Event review (detections and alerts from your Frigate server) • Timeline browsing across cameras • Recordings playback • Export clips to share or save • More of the day-to-day Frigate workflow without leaving your phone SUPPORTING THE APP Porthole is free to use. A small banner on the Live grid and an optional Porthole Pro subscription ($4.99/year) help fund continued development, maintenance, and these upcoming features for Frigate users. Pro removes ads and is billed through your Apple ID—entirely separate from your Frigate server. REQUIREMENTS • A running Frigate NVR with go2rtc live streams • Network access from your device to that server (LAN or HTTPS) If you already self-host Frigate and want a clean native client—not another cloud camera subscription—Porthole is for you.
