Which browsers are officially supported

Overture is built for the modern web. If you've kept your browser reasonably up-to-date in the last 18 months, you're fine. Here's the official compatibility list and what to do if something looks broken.

Officially supported

These browsers are tested against every Overture release. If you hit a bug here, it's a real bug — report it.

• Google Chrome (the last two major releases)
• Apple Safari (the last two major releases on macOS and iOS / iPadOS)
• Mozilla Firefox (the last two major releases)
• Microsoft Edge (the last two major releases — Chromium-based only)
• Brave and other Chromium-based browsers (the last two major releases)

Best results: a desktop or laptop

Overture works in mobile Safari and Chrome and remains responsive on phones and tablets, but the run-of-show canvas is built for a wider screen. We recommend a laptop or desktop when you're actively producing — phones are great for spot-checking during the show.

Not supported

• Internet Explorer (any version) — IE has been end-of-life since 2022; modern Overture features depend on web standards IE never supported.
• Browsers older than two major versions behind current. We don't actively block them, but features may break silently.
• Embedded browsers in messaging apps (e.g. the in-app Slack or Microsoft Teams browsers). Always open Overture in your real browser — those embedded views often strip cookies and lose your session.

Quick check: am I on a supported version?

Easiest answer: visit whatismybrowser.com — it shows your browser name and version. Compare to the latest Chrome, Safari, Firefox, or Edge release histories. If your version is within the most recent two, you're good.

Something looks broken — what now?

1. Hard refresh first

   9 times out of 10, a stale cached file is to blame after a release. Hold Shift and click your browser's refresh button (or Ctrl/Cmd + Shift + R). This forces a fresh download of all assets.

2. Try an incognito / private window

   This rules out conflicting browser extensions (ad blockers, screen reader helpers, or password managers can occasionally interfere). If it works in incognito, an extension is the culprit.

3. Try a second supported browser

   If you usually use Chrome, try Safari or Firefox. If the bug only shows up in one browser, that's gold — include that detail when you report it.

4. Email support

   If the bug persists across browsers, email [email protected] with: your browser + version, your OS, what you were doing when it broke, and a screenshot. We'll usually have a fix or workaround within one business day.

Why we don't support every browser forever

Browsers evolve fast. Restricting to the last two major versions of each modern browser keeps the engineering surface area small enough that we can ship new features confidently and catch real bugs quickly — rather than spending energy on workarounds for browsers your finance team retired three years ago. If you're stuck on an older browser for IT reasons, email us and we'll talk through options.
