### 3/5 — Ça a l’air bien mais..

*2026-08-09*

Ça ne marche pas avec le s3 fourni par nextinpact. Il faut un custom endpoint, minio pourrait marcher mais il faut une région fr1 qui ne peut pas être saisie 
Soit j’ai pas trouvé l’option soit il faudrait l’ajouter. 
Merci

### 3/5 — “Universal” but no support for custom URLs / selfhosted s3 servers

*2026-07-23*

Totally useless for self hosted s3 folks. It’s bizarre that this client doesn’t offer any way to enter a custom URL.

### 5/5 — Does its thing.

*2026-02-11*

Yay! Hooray!

**Developer response:** Thanks you!

### 5/5 — Ca a sauvé ma vie

*2025-11-18*

Application très simple pour migrer 1 bucket sur un autre bucket ça m’a littéralement sauvé la vie !

**Developer response:** Avec plaisir!

### 5/5 — Good app

*2025-10-01*
