Immich vs PhotoPrism: at a glance
What is Immich?
Immich is four release candidates into v3 with every feature note published somewhere else.
The visible release stream is a v3.0.0 RC series — rc.0 through rc.3, cut over eleven days in June — and each entry is the same template: a release-candidate disclaimer, a database and library backup warning, and instructions to move IMMICH_VERSION from v2 to v3 or the rolling v3-rc tag. The actual release notes live on a work-in-progress preview page outside the changelog.
What is PhotoPrism?
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.

Immich
0.0COLLAB
Immich is four release candidates into v3 with every feature note published somewhere else.
◆ Current state
The visible release stream is a v3.0.0 RC series — rc.0 through rc.3, cut over eleven days in June — and each entry is the same template: a release-candidate disclaimer, a database and library backup warning, and instructions to move IMMICH_VERSION from v2 to v3 or the rolling v3-rc tag. The actual release notes live on a work-in-progress preview page outside the changelog.
◆ Where it's heading
What the feed does show is a project running a disciplined pre-release: a rolling RC tag so testers do not have to chase point versions, and two-to-seven day turnarounds between candidates as bugs come in. What it does not show is a single feature, which means anyone tracking Immich through its changelog learns only that a major version is close, not what it changes.
◆ Prediction
A v3.0.0 stable release follows once the RC turnaround lengthens; the entries give no basis for predicting what it contains, because none of them describe it.
PhotoPrism
3.8COLLAB
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
◆ Current state
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.
◆ Where it's heading
The AI work has moved from bundled TensorFlow models to a pluggable pipeline where the model catalog is configuration, not a build artifact — Ollama, OpenAI and Hugging Face identifiers all resolve through the same file. In parallel the media layer keeps absorbing formats other libraries push out to external tools: PSD, layered TIFF, PDF, and now 360°. PhotoPrism is positioning as the thing you point at a mixed archive, not just a photo folder.
◆ Prediction
Expect the format expansion to continue and the vision configuration to keep broadening its provider surface, with the accessibility section added in July likely to grow into a fuller pass.
