Smooth scrubbing through multi-GB/TB live recordings. Voxel-perfect 3D volumetric rendering. Generate presentation and paper ready output. Manual quantification and annotation tools. Built-in reproducible data analysis framework and agent-friendly. Extensible plug-in architecture for building your own analysis pipelines.
Scrub and play 10+ GB OME-TIFF, OME-Zarr, and SCAPE volumes at full resolution. A Rust I/O core and streaming load keep it smooth — no proxies, no precomputation. Set Skip to stride past slowly-varying frames.
Emissive (fluorescence-faithful) and MIP volume modes stay crisp at every zoom. Auto pyramid-level selection picks the right resolution for the camera distance.
Fly (WASD), orbit, or Hybrid — orbit an annotation, then detach into free-look. An orientation minimap and click-to-fly keep you placed, and you switch modes without losing your viewpoint.
Dock the slice and the volume side by side — or float one onto a second monitor. Ctrl+click in 2D to fly the 3D camera to that voxel; the two views always agree on where you are.
Draw box, ellipse, cylinder, or surface regions, rotate and parent them in 3D, and crop the volume to them. Measure per-channel intensity over time — live plot and CSV export — while “Center” tracks a region on a moving object across timepoints.
Per-channel composite with colors, saved presets, and emissive balancing. A subtractive “stain” mode and a custom multi-stop colormap editor round it out.
Add file-format readers, exporters, commands, dockable panels, 3D overlays, and tools from the Plugin Manager. Each plugin runs in its own process, so a broken one can't take the viewer down.
Export frames, sequences, and movies (MP4, GIF, PNG, TIFF) — including keyframed camera flythroughs — with timestamp, scale-bar, and colormap-legend burn-ins. Or write out the raw voxels at full bit depth (OME-TIFF, OME-Zarr, .zarr.zip) with an embedded provenance record.
vizi is designed to facilitate the data exploration and the workflows scientists use.
Smooth scrubbing through long timeseries. Per-channel composite display for multi-fluorophore experiments. Built and tested on data from MicroManager-style pipelines.
FOCO Lab SCAPE compressed-zip files open directly — voxel intensities, channel layout, and physical pixel sizes come from the embedded metadata. T/Z/C dimensions match the file's anatomical axes so Z-scrubbing acts like depth.
Volumetric OME-TIFFs 10+ GB scrub smoothly at full resolution, and OME-Zarr / OME-NGFF stores — Zarr v2 or v3, including single-file .zarr.zip — open natively with their multiscale levels. Plain, compressed, and tiled TIFFs open too; set the T×Z split for ones without OME-XML. CZI, ND2, LIF and ~150 other formats open through the optional Bio-Formats image server.
Named bounding boxes persist per session. Global X/Y/Z crops. Click-to-fly between 2D and 3D. Designed for the inspect-mark-export loop, not just look-and-close.
In the middle of every imaging pipeline — between raw acquisition and downstream analysis or publication.
