May is a modern, self-hosted web dashboard application for vehicle management. It provides a clean interface to log fuel fill-ups, automatically calculate consumption (such as MPG or L/100km), track expenses, schedule maintenance, set reminders, and store related documents across multiple vehicles per user. The app supports full multi-user access, features interactive analytics charts, customizable notifications through email, Pushover, ntfy or webhooks, dark mode, PWA capabilities, and integrations like calendar subscriptions or UK DVLA lookups. Built with Python/Flask, SQLite, Tailwind CSS, and HTMX, it runs easily via Docker and includes a REST API plus PDF report generation for comprehensive fleet tracking. It’s named after James May as part of a fun Top Gear-inspired naming theme. In this step by step guide I will show you how to install May on your UGREEN NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest May v0.15.0 release.

Note: Be careful to enter only lowercase, not uppercase letters.

STEP 4

⚠️Mandatory: Add Read & Write Permissions to the Docker Folder.

STEP 5

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Home then Live connect. Follow the instructions in the image below.

On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
