Where Inventaire excels
Open source and self-hostable
Inventaire is free software (AGPL-3.0), non-profit, and self-hostable. If you care about open source and data sovereignty, Inventaire is a genuinely unique project in this space.
Community book sharing with strangers
Inventaire's core model is making books available to people nearby — for loan, gift, or sale. Your public inventory can be discovered by anyone in your area. It's a distributed, peer-to-peer library system.
Open bibliographic data on Wikidata
Every book you catalog on Inventaire contributes to a shared, open knowledge commons on Wikidata. Your cataloging work improves a resource that benefits everyone, not just your personal library.
Where Plumerie is different
Private family library management
Plumerie treats a family as a unit with a shared library. Up to 5 members see the same catalog in real time. Inventaire treats each user as an individual — family sharing requires workarounds through groups.
Personal library focus with location tracking
Plumerie tracks where each book lives (room, shelf), read/unread status, condition, and want list. These personal library management features are secondary to Inventaire, which is built around community sharing, not personal organization.
Invite-based lending (private by default)
Plumerie's lending is private — you send a loan to a specific person you know. Inventaire's lending is public-first — strangers can request books from your inventory. These are fundamentally different philosophies of lending.
Polished consumer experience
Plumerie is a product optimized for ease of use with Goodreads import, a want list, and a mobile-first interface. Inventaire is a community platform — it's powerful but assumes some familiarity with its model.

The honest summary
Inventaire and Plumerie share values but serve different use cases. Inventaire is a community book-sharing platform — a distributed, peer-to-peer library. Plumerie is a personal and family library management app. Inventaire connects you with strangers who have the book you want. Plumerie helps you manage books you already have and share them with people you know.
Frequently asked questions
Is Inventaire really free?
Yes — it's a non-profit project funded by grants (including EU NLnet/NGI0 funding). There's no premium tier. The code is open source and self-hostable.
Can strangers see my books on Inventaire?
You control visibility per book: public (anyone), friends only, or groups only. But the community model encourages public visibility — that's how book exchanges happen.
Does Inventaire work well for a small personal library?
It can, but its strengths are in community sharing, not personal management. If you mainly want to know what's on your shelf and lend to friends, Plumerie's interface is more streamlined for that use case.
