Immich vs PhotoPrism, which self-hosted Google Photos replacement should you actually run in 2026

[MiguelCardozo]

These two solve genuinely different versions of the same underlying problem, so the right pick depends heavily on what you're actually replacing. If the answer is Google Photos specifically, meaning you want your phone to automatically back up photos in the background, a face search that actually works, and shareable links your non technical family members can open without installing anything, Immich is the clear answer in 2026. It has native, polished mobile apps for iOS and Android with reliable background upload, built in face recognition and semantic search that runs entirely locally using CLIP embeddings and InsightFace, and a fast growing GitHub community that's now the most starred of any self hosted photo project by a wide and growing margin

PhotoPrism takes the opposite philosophy, it's the older, more conservative project, first commit back in 2018, and it treats itself as a library indexing tool rather than a photo backup app. Crucially it does not move your existing photos by default, it indexes them in place, which matters enormously if you already have years of carefully organized folders and don't want a new tool restructuring everything. Its mobile experience is a progressive web app rather than a native app though, meaning background upload is meaningfully weaker than Immich's, if getting phone photos onto the server automatically is your main goal, this is where PhotoPrism loses

Hardware requirements diverge too. Immich's machine learning features, the face recognition and semantic search that make it feel like Google Photos, genuinely benefit from real GPU acceleration, an Nvidia card, Intel iGPU via OpenVINO, or Apple Silicon via Metal Performance Shaders all speed things up considerably, running purely on CPU works but face processing on a large library can take days rather than hours. PhotoPrism is the lighter option, it runs comfortably on hardware with under 6GB of RAM and doesn't demand the same GPU investment, making it the more practical pick if you're deploying on modest, already existing hardware rather than buying something new specifically for this

The honest 2026 recommendation, for most people trying to actually replace Google Photos, meaning automatic phone backup plus real face and semantic search plus easy sharing, Immich wins and it isn't especially close anymore. Choose PhotoPrism instead specifically if you already have a large, well organized existing photo library you don't want reorganized, you're running on modest hardware without a GPU, or you specifically want a calmer, slower moving project rather than one that ships new features every few weeks and occasionally breaks configs between major versions

The distinction between a photo backup app and a library indexing tool is the framing that actually clarified this whole decision for me, I'd been comparing them as if they did the same job when they really don't
