I built a case compatibility checker covering 67 phone models (and open-sourced it)
Why I built this I run a phone accessories blog. Every week the same question shows up in comments and support emails: "I have a Galaxy S24 Ultra — which case fits it?" I was answering it by hand, then linking to a buying guide, then hoping the reader found the right section. That's a bad experience, so I built a tool that just answers it. Case Compatibility Checker — pick a brand, pick a model,…
The author, who runs a phone accessories blog, built a tool to simplify the process of finding compatible cases for various phone models. The Case Compatibility Checker covers 67 models, including phones from brands like Apple, Samsung, Google, OnePlus, HTC, LG, Motorola, Xiaomi, ZTE, and Nokia. The tool provides information on case types, screen protectors, and links to relevant buying guides.
The author designed the tool with both a web front-end and a command-line interface, ensuring that the data and logic were not duplicated. The dataset for the tool was sourced from existing published guides, with each entry linking back to the original post. The author followed Test-Driven Development (TDD) throughout the development process, writing tests first to catch any schema changes.
The project is open-sourced under the MIT license and can be found at github.com/allsmartaccessories/case-compatibility-checker.
