Every litre.
Every kilowatt.
All yours.
Journii is a private, self-hosted vehicle journal. Log fuel and charging sessions, track costs across your whole fleet, and get honest analytics — without handing your data to anyone.

What it does
Everything your logbook should be
No paper. No spreadsheets. No subscription. Just a clean interface that stays out of the way and does its job.
Fuel & charging
Log every fill-up and charging session. Track cost per litre, cost per kWh, and exactly where your money goes.
Fleet in one place
Manage every vehicle you own — BEV, PHEV, hybrid or petrol. Switch between them in seconds.
Real analytics
Efficiency trends, cost breakdowns, monthly spend — visualised clearly so patterns are obvious at a glance.
Your data, your server
Self-hosted. Nothing leaves your machine unless you decide. No subscriptions, no tracking, no data brokers.
How it works
Simple by design
Add your vehicles
Register each car, van or bike with its powertrain type. Journii adapts efficiency units automatically — L/100km for petrol, kWh/100km for BEV.
Log as you go
After every fill-up or charge, open Journii and enter the amount, price, and odometer. Takes about 20 seconds.
Watch the trends
The stats workspace shows monthly cost trends, efficiency over time, and a breakdown across your whole fleet — all automatically.
