Browser support
Browsers we build and test against.
OurCommons is built for modern browsers. Older versions may load the page but render or behave incorrectly, particularly on the financial surfaces, which lean on recent CSS and JavaScript features. If your browser falls outside this matrix you'll see a banner at the top of the page.
| Browser | Minimum version | Released |
|---|---|---|
| Google Chrome (desktop) | 120+ | December 2023 |
| Microsoft Edge | 120+ | December 2023 |
| Mozilla Firefox | 120+ | November 2023 |
| Safari (macOS) | 17+ | September 2023 |
| Safari (iOS / iPadOS) | 17+ | September 2023 |
| Chrome on Android We re-evaluate this floor each quarter as Chrome ships new majors. | 130+ | Approximately last 2 major releases |
What happens on older browsers
We do a server-side check of the browser's User-Agent on every page request. If it identifies as below the matrix above, a small banner appears at the top of the page warning that some features may not work as expected. You can dismiss it for 30 days, but the safer option is to update your browser.
We do not block access. If you choose to continue, OurCommons will still load. It may render incorrectly. Financial surfaces in particular may not behave as designed.
Why this matrix
Our build pipeline (Next.js 16 + Turbopack) targets a modern browserslist. Anything below the matrix above runs on a CSS / JS baseline our toolchain no longer emits compatibility shims for. Rather than fail silently, we surface this to you. If you need to run OurCommons on an older browser for a specific reason, get in touch.
