BudMinder

Your cannabis grow journal, on your own hardware.

BudMinder keeps every plant's daily notes and photos, your seed inventory, want list, live sensor readings and smoke reports together in one place. It runs locally on your computer or home server, completely free and open source.

Why growers use it

Track your grow with a journal that stays on your own hardware.

Your grow, on your hardware

No cloud accounts, no corporate tracking, and no treating your data as a commodity to be sold.

No subscriptions or paid tiers. The code is public under the MIT license.

Connect actions to results

Each day's notes, watering and feeding sit directly beside that day's photos.

Seed to smoke

Rate every harvest or dispensary pickup. Dry and cure times fill themselves in.

Instant strain lookups

Import a strain in one click, complete with breeder, lineage, flowering times, cannabinoids and terpenes.

The hardware you already own

From seed to jar

Every stage of your grow, on pages designed to work seamlessly together.

01

Plant pages

Questions

Is it free?

Yes. BudMinder is free and open source under the MIT license with no subscriptions or paid tiers.

Does my data leave my computer?

No. Your journal notes, photos and sensor readings stay strictly on your local hardware. BudMinder only connects outward when you request it, such as searching public strain catalogs or reading your AC Infinity sensors.

Do I need sensors?

No. The journal, photos, strains, seed vault and smoke reports work completely without hardware. Connect sensors whenever you are ready.

What does it run on?

Any platform running Docker (including Unraid and Raspberry Pi), or as a standalone app on Windows, macOS or Linux. It uses SQLite by default, with PostgreSQL support if you prefer.

Is there a demo?

A live demo is coming soon. Until then, the screenshots on this page come from the demo's real grow, so you can see exactly what BudMinder looks like.
