Flash Render

A countdown that’s never a copy.

Most timer tools draw your countdown once and hand out that stored copy for a minute or more. Flash Render draws it again every time an inbox asks for it, so every reader sees the real time left, accurate to the second. Don’t take our word for it: reload the two timers.

Try it: one timer, served two ways

Flash Render

Drawn for every request

Drawn … s ago

Stored copy

Kept 2 minutes, like most timer tools

Drawn … s ago

Same timer, same renderer. Reload, and Flash Render picks up at the real time while the stored copy jumps back to when it was kept, showing time that has already gone.

How it works

Most timer tools send a photo of the clock. Flash Render sends the clock.

A stored countdown was right when it was drawn. Every minute it sits in storage it's a minute further from the truth, and the readers opening near your deadline are the ones who see it.

Two ways to serve a countdown to a sale ending at 12:00. Most timer tools draw it once at 11:56 and hand out that copy, so readers opening at 11:57 and 11:58 both see 4 minutes left, 1 and then 2 minutes behind. Flash Render draws it for each open, so they see 3 minutes and then 2 minutes left, right to the second.

The reason why

Why cut the corner? Because drawing every open is hard.

  1. 1

    Drawing every open is real work

    Every open is a new picture to draw. A send to 100,000 readers can be 100,000 drawings, many of them in the same few minutes.

  2. 2

    So most tools draw once and reuse it

    Keeping a copy and handing it out again is cheaper. The price is a clock that's a minute or more behind, and readers near your deadline see it.

  3. 3

    We built Flash Render to do the work

    flashtimer's own engine was built to draw a countdown on every request, so there's never a reason to keep a copy of a live one.

On a global network

Drawn close to whoever asks for it.

Flash Render runs on Cloudflare's global network, in data centres around the world, so each countdown is drawn near the inbox or phone asking for it.

  • Drawn near whoever asks

    Each request is drawn in the data centre nearest whoever made it: your reader's phone, or the image proxy their inbox uses, like Gmail's.

  • No single server to queue behind

    A send that opens all at once is spread across the network, not lined up at one machine of ours.

  • Sent marked “don’t keep a copy”

    Every live countdown goes out no-store, so Gmail, Apple Mail and browsers are told never to keep an old one.

Test any timer

Check any timer in 30 seconds.

The demo above runs on our page. This one runs on anyone's timer, ours included.

  1. 1

    Open the timer on its own

    In a test email or the tool's preview, right-click the countdown and choose Open image in new tab.

  2. 2

    Note the time, wait, reload

    Note the seconds it starts on, wait half a minute, then reload the tab.

  3. 3

    Read the result

    If it starts from the real time left, it was drawn for you. If it starts where it did before, or jumps back, you're looking at a stored copy.

Why we built it this way

A countdown in an email has one job: to be right when it’s opened. We built Flash Render so it always is, for every reader, right up to the deadline.
