About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

Paparazzi is an Android snapshot-testing library that renders application screens without a physical device or emulator. JVM tests can render Views and Compose, record golden images, and verify later output against those baselines.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Key features

Render Views and Compose in JVM tests and record images

Paparazzi can inflate Views or render Composables and save the result as a snapshot without starting a device or emulator.

Sources: [2]

Manage golden images with record and verify Gradle tasks

recordPaparazziDebug writes baseline images and verifyPaparazziDebug compares current rendering with those goldens, producing failure diffs when results change.

Sources: [2]

Best fit

Fits Android teams that want visual regressions reviewed in CI

Components, screen states, and Compose UI can be kept as versioned goldens so unintended spacing, color, and layout changes surface as reviewable diffs.

Sources: [2]

Before adoption

Plan golden storage and evaluate the 2.0 alpha line separately

The README recommends Git LFS for snapshot files. The latest 2.0.0-alpha05.1 release changes the rendering model and notes that some goldens need to be recorded again, so migration from stable 1.3.5 should be evaluated independently.

Supplemental curator note

Paparazzi is strong for visual regression checks in CI, but adoption includes a policy for storing and reviewing golden images. Evaluate the 2.0 alpha line separately because its rendering model changes can require snapshots to be recorded again.

Try it in 3 steps

  1. 1

    Clone the stable 1.3.5 source

    Shallow-clone the reviewed stable 1.3.5 tag rather than the active 2.0 alpha line.

    git clone --depth 1 --branch 1.3.5 https://github.com/cashapp/paparazzi.git && cd paparazzi
  2. 2

    Record sample golden images

    Run the sample task documented in the README to record Debug snapshots as golden images.

    ./gradlew :sample:recordPaparazziDebug
  3. 3

    Verify rendering against the goldens

    Compare the current sample rendering with the recorded goldens and confirm the snapshot test passes.

    ./gradlew :sample:verifyPaparazziDebug
