Your Logbook.
Your Data. Your Rules.
The open-source pilot logbook for GA. It works out your night time from the real sunset, checks your currency against EASA and FAA rules, and lets you write your own rules for everything they don’t cover.
Open source on GitHub. Funded by the pilots who use it.
What NinerLog does.
A modern pilot logbook, built for the way you fly. Open source, free to use, and every feature is in the box.
Open Source
See the code. Host it yourself. No vendor lock-in. Ever.
Flight Logging
Log every detail, from block times to IFR approaches. Quick entry templates turn logging into a 30-second habit.
Quick Log New
Tap off block, takeoff, landing, on block — the flight logs itself, block times and all, works offline.
Powerful Search New
One box searches registration, type, ICAO, and remarks at once. Find any flight in seconds.
Multi-License
PPL, CPL, ATPL across EASA, FAA, and any authority worldwide. All in one logbook.
Currency Tracking
Automatic 90-day recency, EASA revalidation, FAA 61.57. It tells you the date it runs out, not just whether you’re current.
Your Own Rules New
Club minimums, insurance requirements, personal limits — build the currency rule yourself, then share it with your club by link.
Instructor Signing New
Sign in person or send a secure link. Signed flights lock — your training record stays as endorsed.
Credentials & Medicals
Track expiry dates for medicals, ratings, and credentials. Get warned before they lapse.
Language Support
Full German support today, with more languages coming. Use NinerLog in the language you prefer.
Reports & Maps
Your career in seven chapters — hours, aircraft, places, instrument, patterns, records — plus route maps and airport heatmaps.
Import & Export
Twelve logbook formats detected automatically on the way in. CSV, JSON, and a signable EASA/FAA PDF logbook on the way out.
Cloud Backup New
Automatic offsite backups to a destination you own — any S3-compatible bucket, SFTP server, or WebDAV share. Your storage, your keys.
Flying Club Ready Self-hosted
Run NinerLog for your whole club. Admin panel, user management, and announcements built in — one instance, every pilot’s own logbook.
Login Security
Protect your logbook with passkeys (Face ID, Touch ID, security keys) or two-factor authentication via your favorite TOTP app.
Get flying in under a minute.
Three waypoints. That’s your flight plan. No complicated setup, no credit card.
Sign Up
Email and password. Takes 30 seconds. No credit card, ever.
Log Flights
Add your license, aircraft, and go. Quick entry makes logging second nature.
Stay Current
Automatic 90-day and revalidation tracking. EASA FCL.740 and FAA 61.57 built in.
Your logbook is a legal record of your
entire flying career. It deserves a
platform you can trust.
Open Source
Every line of code is public on GitHub. Audit it. Fork it. It’s yours.
Data Freedom
Export your entire logbook as CSV, PDF, or JSON. Anytime. No limits. No paywall.
No Vendor Lock-In
If NinerLog ever stops, self-host it yourself. Your logbook lives on, guaranteed.
Community-Owned
Funded by pilots who use it. No VC money. No ads. No hidden agenda. What that actually means →
