Downstage

The stage timer that survives the show. Countdown, count-up and clock for live events — pushed to any display or over NDI, and driven from a phone, a desk, or a single command.

Setting up a show clock? Read the guide: How to run a stage timer on a Mac.

It doesn't blink.

The audience display sits at screen-saver window level, joined to every Space — so Mission Control, Exposé and space-switching can't pull the timer off-screen mid-show. It's the one thing every other timer gets wrong, and the reason this one has run live for years.

What it does

  • 01

    Countdown, count-up & clock

    Quick-set 5/10/20/30/60, live ±1 minute, pause and stop. Overtime counts up past zero in red. Plus a clean time-of-day clock mode.

  • 02

    Warning colours

    Amber at five minutes, red at one — both thresholds configurable, or switched off for a constant colour. Custom text and background colours throughout.

  • 03

    Messages, blackout & attention

    A big auto-fitting message overlay, instant blackout, and a one-second strobe to grab the room when you need every eye on the screen.

  • 04

    External displays & NDI

    Mirror the timer to any connected screen, or send it as an NDI source straight into your vision mixer, OBS or Resolume — no second display required.

  • 05

    Phone & lectern remote

    A dependency-free web remote puts big start / stop / message buttons on any phone, and a lectern display turns a spare iPad into a presenter screen.

  • 06

    Running order

    Build a named cue list, step Prev / Next, or let cues follow on automatically. Save and share whole running orders as .dscue files.

A look at it

Drive it from anything

Every control is a single UDP datagram on port 6969 (or the matching web-remote URL). Wire Downstage into your show-control, a stream deck, a QLab cue — whatever runs the show.

Support

Downstage is built and supported by HALF GREY BEAR. The user guide covers setup, outputs, the remote and the running order in full. If you're still stuck — or you've found something we should fix — email the studio and a human will answer.

Which macOS does it need?
macOS 13 Ventura or later, on Apple silicon or Intel.
Do I need to install anything for NDI?
No — Downstage bundles the NDI runtime, so NDI output works the moment you switch it on. Nothing else to install.
Why does it ask for local-network access?
So it can listen for the phone / web remote and UDP control on your network, and send the NDI video feed. It's all on your own LAN — nothing is sent to us or over the internet.
How is it distributed?
As a free, signed and notarised direct download from this page — one build with everything, including full NDI output. It checks for updates itself, so you'll always know when there's a new version.
Can I install it with Homebrew?
Yes: brew install --cask halfgreybear/tap/downstage. The cask tracks new releases automatically, and the app still updates itself in-app.

Privacy

Downstage collects no data. No account, no analytics, no tracking — nothing is sent to HALF GREY BEAR or to anyone else.

The only network traffic is on your own local network: the phone / web remote, UDP control, and (if you enable it) the NDI video output. Your settings and cue files stay on your Mac.
