How do I get notified when a long-running script finishes?

Some jobs take twenty minutes, some take three hours — data processing, migrations, big test suites, exports. Checking back every few minutes breaks your focus and you still end up losing time. The clean answer is to let the script tell your phone when it's finished. Lert turns that into a single line: your unique link is the credential, so there's no auth and nothing to install.

Set it up in under 30 seconds

1. Download the app. Open it once — there's no account to create.
2. Copy your link. A private link like https://lert.dev/p/your-id is on screen; one tap copies it.
3. POST at the end of the script. Include how long it took so the buzz tells you everything at a glance.

Kick it off, go do something else, and your phone buzzes when it's done — even locked in your pocket.

The code

import time, requests

start = time.time()
run_long_job()                       # your slow work
mins = round((time.time() - start) / 60, 1)

requests.post("https://lert.dev/p/your-id", json={
    "title": "Job finished",
    "body": f"Done in {mins} min"
})

No headers beyond JSON, no auth token, no SDK. The same idea works from bash — just capture the start time and append a curl at the end. Not a coder? Tell your AI: "POST to my Lert link when this finishes."
