Tool: Latest Chromium ASan builds
This tool allows you to quickly download the latest Chromium AddressSanitizer (ASan) builds, according to data from the storage bucket and ChromiumDash.
Since March 16, 2022, this tool shows release ASan builds for Windows, ChromeOS, Linux, and Mac. Previously it only showed Windows builds.
On August 4th, 2022, Chromium added a Python script to get ASan builds: get_asan_chrome.py

Why I created this tool
The Chromium ASan documentation points to the storage bucket directly and instructs users to set the prefix manually to narrow down the platform and commit number. (Update: Since September 2022 the documentation also points to a useful Python script.) This seems like a lot of overhead for something I do on a regular basis, especially without knowing the latest commit number with an ASan build (not all commits get a build) or after forgetting where to find the latest commit number.
The process above is also prone to human error. Recently I accidentally downloaded a month-old build instead of the latest build. Guess who spent a few hours investigating a fixed UAF bug? 🙋🏻♂️
Hope this is as useful to others as it will be to future me.
