Papa Stud.io

Features

Everything you need to triage diffs

A focused toolkit, not a platform. Local-first, fast, and built around how mobile engineers actually work.

Android & iOS tools

Works out of the box with Paparazzi, Roborazzi, and Compose Screenshot Testing. iOS via swift-snapshot-testing in beta.

Multiple diff modes

Delta, toggle, and slider comparisons. Pinch-zoom and pan to inspect pixel-level differences.

One-click accept

Promote the rendered image over the golden, one failure at a time or in bulk for a whole scan.

Monorepo aware

Scans multi-module Gradle projects, groups failures by module, and tracks status across rescans.

Video export

Stitch a scan's failures into a short video — perfect for sharing diffs in PRs or design reviews.

Live watch mode

Keep a scan watching your build outputs — new failures show up the moment Gradle finishes.

Review CI results remotely

Paste a CI run's result tarball URL (e.g. a Jenkins artifact) — or upload one or more .zip/.tar/.tar.gz archives from disk. Papa Stud.io overlays the failures onto your local project and scans against your local goldens. Multiple archives are merged into one scan; if two disagree on a file's content, the scan is aborted and the conflicts are listed.

Install

Up and running in seconds

macOS via Homebrew. A few commands, no extra setup.

brew tap eboudrant/tap
brew trust eboudrant/tap
brew install --cask papastudio

brew trust is required on Homebrew 6.0+ before it will load a third-party tap. On older Homebrew that line is unnecessary — skip it.

Review screenshot failures, side-by-side.
