Thunderbird, l'embl\u00e9matique client de messagerie open-source qui a plus de 20 ans d'histoire, entre dans un tout nouveau territoire. En avril 2025, l'\u00e9quipe a annonc\u00e9 le projet Thunderbird Pro<\/a><\/strong> - un ensemble de services en nuage payants con\u00e7us pour transformer le client de bureau en un outil de communication complet. \u00c9cosyst\u00e8me<\/a>. Il ne s'agit pas de transformer Thunderbird en un produit payant, mais d'un compl\u00e9ment optionnel qui offre une alternative libre aux \u00e9cosyst\u00e8mes. Google<\/a> a Microsoft<\/a>.<\/p>\n\n\n\n

Les trois piliers Thunderbird<\/a> Pour<\/h2>\n\n\n\n

Sous la banni\u00e8re Thunderbird Pro se trouvent trois services, chacun d'entre eux comblant une lacune sp\u00e9cifique de l'offre existante.<\/p>\n\n\n\n

Thundermail<\/strong> est le premier h\u00e9bergement de messagerie directement issu des cr\u00e9ateurs de Thunderbird. Il prend en charge les protocoles IMAP<\/a>, SMTP<\/a> a JMAP<\/a>, qui assure la compatibilit\u00e9 non seulement avec Thunderbird, mais aussi avec d'autres clients. Les utilisateurs peuvent choisir une adresse avec le domaine @thundermail.com ou @tb.pro, ou ajouter leur propre domaine. Le tableau de bord permet de g\u00e9rer les alias et les param\u00e8tres du compte. Les serveurs ont \u00e9t\u00e9 d\u00e9plac\u00e9s des \u00c9tats-Unis vers l'Allemagne et l'Union europ\u00e9enne, ce qui sera particuli\u00e8rement appr\u00e9ci\u00e9 par les utilisateurs europ\u00e9ens sensibles \u00e0 la question de l'acc\u00e8s \u00e0 l'Internet. Comp\u00e9tence<\/a>.<\/p>\n\n\n\n

Nomination<\/strong> est un outil de planification pour la gestion des rendez-vous. Cr\u00e9\u00e9 \u00e0 l'origine comme une application web autonome, il s'int\u00e8gre d\u00e9sormais directement dans la fen\u00eatre de composition de Thunderbird - lorsque vous composez un courriel, vous pouvez ins\u00e9rer un lien vers une r\u00e9union sans passer d'une application \u00e0 l'autre. Le service prend en charge les connexions avec Zoom et CalDAV. La planification de groupes est \u00e9galement pr\u00e9vue, une fois que le d\u00e9veloppement de protocoles tels que VPOLL le permettra.<\/p>\n\n\n\n

Envoyer \u00e0<\/strong> est un outil de partage de fichiers avec de bout en bout<\/a> qui s'ajoute \u00e0 la fonction Filelink existante. Les utilisateurs Pro b\u00e9n\u00e9ficient d'un espace de stockage de 500 Go, sans limite de taille pour les fichiers individuels. Send a fait l'objet d'un audit de s\u00e9curit\u00e9 externe, dont les r\u00e9sultats seront rendus publics. Le service est le successeur spirituel de l'ancien service de messagerie \u00e9lectronique Firefox<\/a> Envoyer, mais avec un remaniement important de la base de code.<\/p>\n\n\n\n

Ces trois services sont libres et auto-h\u00e9berg\u00e9s - les organisations disposant de leur propre infrastructure peuvent les faire fonctionner ind\u00e9pendamment de Thunderbird.<\/p>\n\n\n\n

Prix et disponibilit\u00e9<\/h2>\n\n\n\n

Le premier niveau d'abonnement est Plan de r\u00e9servation anticip\u00e9e<\/strong> pour 9 $ par mois, ce qui inclut les trois services. L'\u00e9quipe qualifie ce plan de tarif de lancement, qui couvre le co\u00fbt de l'h\u00e9bergement, du stockage et de l'h\u00e9bergement. S\u00e9curit\u00e9<\/a>. D'autres niveaux de prix devraient \u00eatre ajout\u00e9s une fois que la plateforme sera stabilis\u00e9e.<\/p>\n\n\n\n

En f\u00e9vrier 2026, des tests internes sont en cours avec l'\u00e9quipe de Thunderbird. Ils seront suivis d'un test ferm\u00e9 avec les contributeurs de la communaut\u00e9, puis d'une mise \u00e0 disposition progressive aux personnes inscrites sur la liste d'attente. La version b\u00eata ouverte Early Bird est pr\u00e9vue pour le premier semestre 2026.<\/p>\n\n\n\n

Ce qui reste gratuit<\/h2>\n\n\n\n

L'\u00e9quipe insiste \u00e0 plusieurs reprises sur un principe fondamental : Les clients Thunderbird pour ordinateur de bureau et pour t\u00e9l\u00e9phone portable restent gratuits<\/strong>. Toute fonctionnalit\u00e9 pouvant \u00eatre mise en \u0153uvre directement sur l'appareil ne sera pas plac\u00e9e derri\u00e8re le paywall. Thunderbird Pro n'est qu'un compl\u00e9ment pour les services en nuage qui, par nature, n\u00e9cessitent une infrastructure de serveur. Les revenus tir\u00e9s des abonnements sont destin\u00e9s \u00e0 couvrir les frais de fonctionnement et \u00e0 compl\u00e9ter le financement par les dons, et non \u00e0 le remplacer.<\/p>\n\n\n\n

R\u00e9action de la Communaut\u00e9<\/h2>\n\n\n\n

L'annonce de Thunderbird Pro a suscit\u00e9 des r\u00e9actions mitig\u00e9es au sein de la communaut\u00e9. L'accueil extr\u00eamement positif r\u00e9serv\u00e9 \u00e0 l'id\u00e9e elle-m\u00eame - de nombreux utilisateurs manquaient depuis longtemps de services en nuage int\u00e9gr\u00e9s qui ne les obligeraient pas \u00e0 d\u00e9pendre de grandes entreprises technologiques. La transparence du d\u00e9veloppement est \u00e9galement \u00e0 saluer : l'\u00e9quipe publie r\u00e9guli\u00e8rement des mises \u00e0 jour, les audits de s\u00e9curit\u00e9 seront publics et tous les services sont open-source.<\/p>\n\n\n\n

La plainte la plus fr\u00e9quente est Prix<\/strong>. Neuf dollars par mois, c'est ce que l'on appelle souvent un prix trop \u00e9lev\u00e9 dans les commentaires des articles officiels, surtout par rapport aux services d\u00e9j\u00e0 en place. ProtonMail propose un plan de base pour 4 euros, Tuta<\/a> pour 3 euros - ces deux services fonctionnent depuis des ann\u00e9es et ont une large base d'utilisateurs.<\/p>\n\n\n\n

Une partie de la communaut\u00e9 s'interroge \u00e9galement sur la relation avec Mozilla et sur l'ind\u00e9pendance \u00e0 long terme du projet. D'autres utilisateurs soulignent que Thundermail ne prend pas encore en charge POP3, ce qui constitue un obstacle pour les utilisateurs qui pr\u00e9f\u00e8rent le stockage local sans copie sur le serveur.<\/p>\n\n\n\n

D'un point de vue technologique, l'intention d'ajouter un service \u00e0 l'avenir Assister<\/strong> - Assistant IA pour le flux de courrier \u00e9lectronique, d\u00e9velopp\u00e9 en collaboration avec Flower AI et ax\u00e9 sur l'apprentissage f\u00e9d\u00e9r\u00e9 avec pr\u00e9servation de l'environnement. Vie priv\u00e9e<\/a>. Toutefois, ce service est encore en phase de recherche et de d\u00e9veloppement et ne fera pas partie de l'offre initiale.<\/p>\n\n\n\n

Contexte plus large : 2025, une date charni\u00e8re<\/h2>\n\n\n\n

Thunderbird Pro n'a pas \u00e9t\u00e9 cr\u00e9\u00e9 dans le vide. L'ann\u00e9e 2025 a apport\u00e9 un certain nombre de changements majeurs pour Thunderbird. Le client de bureau est pass\u00e9 \u00e0 un cycle de publication mensuel, la version 140 \u201eEclipse\u201c a apport\u00e9 une am\u00e9lioration majeure \u00e0 la base de code, et la version 145 prend enfin en charge Microsoft Exchange de mani\u00e8re native, sans n\u00e9cessiter d'ajouts de la part de tiers. Sur le plan mobile, le d\u00e9veloppement du client Android se poursuit et la premi\u00e8re version b\u00eata pour iOS est imminente.<\/p>\n\n\n\n

Pour la premi\u00e8re fois de son histoire, Thunderbird construit syst\u00e9matiquement un \u00e9cosyst\u00e8me qui va au-del\u00e0 du client de bureau, et ce dans le respect des valeurs qui ont d\u00e9fini l'ensemble du projet : ouverture, transparence et respect de la vie priv\u00e9e des utilisateurs.<\/p>\n\n\n\n

R\u00e9sum\u00e9<\/h2>\n\n\n\n

Thunderbird Pro repr\u00e9sente une tentative ambitieuse de cr\u00e9er une alternative libre aux \u00e9cosyst\u00e8mes de communication int\u00e9gr\u00e9s des grandes entreprises technologiques. La combinaison de l'h\u00e9bergement du courrier \u00e9lectronique, de la planification des r\u00e9unions et du partage de fichiers crypt\u00e9s - le tout sous un m\u00eame toit, en open source et en auto-h\u00e9bergement - n'a pas d'\u00e9quivalent direct dans les offres actuelles.<\/p>\n\n\n\n

Toutefois, le projet n'en est qu'\u00e0 ses d\u00e9buts. Il reste un certain nombre d'\u00e9tapes \u00e0 franchir avant le lancement complet et la question de la comp\u00e9titivit\u00e9 des prix reste ouverte. Pour ceux qui souhaitent \u00eatre pr\u00e9sents d\u00e8s le d\u00e9but, il est possible de s'inscrire sur une liste d'attente \u00e0 l'adresse suivante tb.pro<\/strong>.<\/p>","protected":false},"excerpt":{"rendered":"
