NOTAMs in your terminal.

The notamify command line looks up NOTAMs, runs briefings and manages Watcher. It prints readable text in your terminal and JSON when you pipe it into a script.

Example uses of the notamify command line:

  • Brief a flight: notamify briefing flight create --origin EPWA@now/+2h --destination EGLL@+2h/+3h --aircraft B738 --wait --yes
  • What changed overnight: notamify notams expired EGLL EPWA --after -12h
  • Around a site: notamify notams nearby --lat 51.5033 --lon -0.0195 --radius 5 --start now --hours 24
  • Look back in time: notamify notams archive EDDF --date 2025-09-20 --category AERODROME

Watcher brings new NOTAMs to you.

Tell Watcher which airports and which effects matter. Each new NOTAM that matches goes to your webhook or inbox, with a delivery target of three minutes.

Turn on lifecycle messages and Watcher also tells you when a NOTAM it delivered is cancelled or replaced. Every webhook is signed with X-Notamify-Signature, and sandbox listeners send test NOTAMs while you build.

Example Watcher flow. A listener watches EPWA and EGLL for closed runways, taxiways and aprons, with lifecycle messages on.

  • A3398/26 LFPG, published 08:07Z: RWY 09R/27L CLSD DUE WIP. Filtered out.
  • A4518/26 EGLL, published 08:09Z: RWY 09L/27R CLSD 2200-0500 DUE WIP. Delivered at 08:11Z as interpretation.
  • A4521/26 EGLL, published 08:10Z: VOR/DME LON 113.60MHZ BEARING FLUCTUATIONS 155-195 DEG. Filtered out.
  • A3305/26 EPWA, published 08:12Z: APN 2 CLOSED. Delivered at 08:14Z as interpretation.
  • A5521/26 EDDF, published 08:13Z: RWY 07C/25C CLSD. Filtered out.
  • A4530/26 EGLL, published 08:16Z: RWY 09L/27R CLOSURE CANCELLED. Delivered at 08:17Z as lifecycle.

Watcher costs 1 credit for every 5 NOTAMs delivered. Lifecycle messages are free, and so is managing listeners. Test it on your laptop with notamify webhook listen --tunnel.
