Viewport Scopes stands out in the superhive library for pulling scope data straight from the viewport in real time, and for optionally routing that data into the image editor so you can reuse Blender's native scopes.
Viewport Scopes is a Blender add-on from Erasers45-Studios that brings real-time scopes to the viewport, featuring a histogram and a vectorscope. The histogram includes display settings familiar from Blender's default histogram in the image editor, letting you switch between RGB and Luma channels and zoom into the histogram. The vectorscope displays the hue and saturation of the viewport in real time.
Alternatively, you can draw the viewport color data directly into an image texture and read it inside the image editor, giving you access to Blender's native scopes, including the waveform and its other settings, in real time. An overlay editor mode lets you position and toggle scopes directly in the viewport.
The scopes run in real time even on lower-end machines. A few limitations apply: it does not yet differentiate between color transformations, it's recommended for Eevee or Cycles due to API limitations, and loading a different blend file while the scopes are running can break it because of a Blender bug in how modal operators are handled.
Viewport Scopes is best for blender artists managing color, lighting and composition who want real-time histogram and vectorscope readouts in the viewport.
Viewport Scopes is completely free to download and use.
Viewport Scopes lists compatibility with Blender 4.3 through 5.0. It was first released for Blender 4.3 in April 2025, and a later update added support for Blender 4.4 and 4.5. It is a Blender extension-compatible add-on, so it installs as an add-on within Blender. If you're on an older Blender build, check the developer's page to confirm your version is covered before installing, since support is tied to these listed releases.
Viewport Scopes is recommended for Eevee or Cycles only, due to API limitations noted by the developer, and both render engines are listed as the ones it uses. It also does not yet differentiate between different color transformations, so keep that in mind when reading the scopes. There is no stated support for other engines, so Eevee and Cycles are the reliable choice if you depend on accurate real-time histogram and vectorscope data in the viewport.
Viewport Scopes is listed as free here. Licensing can change over time, so for the current terms and any purchase details, check the developer's page. The add-on is distributed under the GPL license and is built by Erasers45-Studios as a Blender add-on. The most recent version listed is 1.0.2 from August 2025, and a demo video is available if you want to see more before installing.
Viewport Scopes has a few documented limitations. Loading a different blend file while the real-time scopes are running can break it, due to a Blender internal bug in how it handles modal operators, so save your work first. It also does not yet differentiate between different color transformations, and it's recommended for Eevee or Cycles only because of API limitations. The 1.0.2 update fixed an issue where histogram and scope data weren't calculated properly across multiple viewport areas.
