A fast viewer for your renders.

A shortcut-first viewer for EXRs, images, and video. Simple by default. Powerful one keystroke away.

Linux macOS Windows Quick tour

justview is for the moment after a render finishes
and before you move on.

It opens fast, keeps the frame central,
and keeps common inspection tools one key away.

New users can open, play, copy, and export immediately.
Power users can stay on the keyboard while moving through AOVs, scopes, grades, crops, split panes, and review tools.

The goal is simple:
less time preparing to inspect an image,
more time deciding what to do next.

Most image tools ask you to build a workspace
before you can inspect a frame.

justview starts with the frame instead.

A sample workflow

From first playback to final checks.

Follow one EXR sequence through a small selection of what justview can do.

justview displaying eleven stages of the coal splash sequence in a frame grid
justview comparing normal, zebra, false color, high-pass, chroma, and black-crush analysis views
justview comparing beauty, noisy color, and cryptomatte layers in an AOV grid
justview grading frame 4 with lift, gamma, gain, saturation, contrast, grain, and bloom controls visible
justview comparing saved grades on frame 4 in a preset grid
justview showing coal and dunes images with beauty and analysis views across four split panes
justview showing a locked pixel sample with scene-linear values and a display color readout

This is only a preview.

Why it works

Open the render first. Bring in tools only when you need them.

Open, play, copy, or export immediately.
Then use shortcuts for the review work you do all day.

Everyday review

Open

Drop in an EXR sequence, still, MOV, or MP4. No project setup.

Inspect

Switch AOVs, read scene-linear pixels, open metadata, and bring scopes onto the frame.

Decide

Compare A/B versions, check delivery crops, copy a still, or export a review movie.

Viewer tools

Small app. Real viewer tools.

The app stays focused, but the tools are real. Color, image data, playback, comparison, and export tools are built for everyday render review.

Playback
EXR sequences, stills, MOVs, and MP4s with caching, in/out points, and proxy playback
Color
Bundled ACES 2.0 OCIO display pipeline with per-shot input color
EXR
AOV browsing, channel isolation, data layers, scene-linear pixels, and full file metadata
Analysis
Waveform, RGB parade, vectorscope, histogram, zebra, false color, high-pass, chroma, and black-crush views
Compare
A/B wipe, split panes, sequence grids, and multi-image stitch layouts
Grade

Export

Made by one person

justview is free because I want artists to use it.

justview is solo-built around the small frictions that show up while checking renders: launch fast, trust the color, inspect a pixel, check an AOV, export a review movie, then get back to work.

Support helps me keep it fast, signed, packaged, tested, and useful across macOS, Windows, and Linux.
