EteSync offers a robust solution for secure, end-to-end encrypted personal information synchronization, covering calendars, contacts, and tasks across Android, desktop, and web. While EteSync excels in privacy and open-source transparency, users might seek alternatives due to specific feature requirements, pricing preferences (paid hosting vs. self-hosting), or ecosystem compatibility. This article explores top EteSync alternatives that offer similar or expanded functionalities for keeping your personal data synchronized and secure.
Top EteSync Alternatives
Whether you're looking for a fully self-hosted solution, a more integrated cloud service, or specific sync capabilities, these alternatives provide excellent options for managing your digital life.
Nextcloud
Nextcloud is a powerful open-source platform providing a safe home for all your data. It allows you to access and share files, calendars, contacts, mail, and more from any device, on your terms.

It's available across Free, Open Source, Mac, Windows, Linux, Web, Android, iPhone, Android Tablet, iPad, and can be Self-Hosted or via Cloudron, making it a highly versatile choice for those prioritizing self-sovereignty and a broad feature set.
iCloud
iCloud, from Apple, allows you to store email, contacts, calendars, photos, music, books, apps, and more in the cloud, accessible across all your devices. As a Freemium service available on Mac, Windows, Web, iPhone, and iPad, iCloud offers robust cloud storage and security & privacy features.

DAVx5
DAVx5 is a free and open-source Android application (available on Android and Android Tablet) designed to sync your contacts, calendars, and tasks. It provides two-way sync for address books, calendars, and task lists using CalDAV, CardDAV, and WebDAV protocols.

Nextcloud Contacts
Nextcloud Contacts is the user interface for Nextcloud's CardDAV server. This free, open-source web-based application (also self-hostable) integrates seamlessly with Nextcloud, focusing specifically on contact management.

Available on Web, Android, iPhone, Android Tablet, and Self-Hosted via Cloudron, it focuses on contacts and journaling.

AkrutoSync
AkrutoSync is a commercial Windows software that automatically and privately syncs Outlook PC contacts, calendar, tasks, and notes directly with any Android, Windows Phone, iPhone, or iPad. It differentiates itself by keeping information off the cloud, offering a secure, ad-free, direct sync solution.

It supports multiple calendar profiles and offers features like Exchange integration and compatibility with apps that sync with Google Calendar.

GO Contact Sync Mod
GO Contact Sync Mod is a free and open-source tool for Windows designed to synchronize your Microsoft Outlook contacts with Google Mail.

e2ee cloud
e2ee cloud is an open-source, self-hosted, end-to-end encryption software for file storage. Available as a free web application that can be self-hosted, it allows users to upload and download files in their browser with all files and folders being encrypted.

Dex
Dex is a Freemium personal CRM available as a web application and Chrome extension. It's designed to be simpler than traditional sales CRMs, helping users keep in touch with important contacts by providing reminders and a clear visualization of interactions.
