Project history and usage

vdirsyncer is a command-line synchronization tool for calendars and address books. It bridges CalDAV, CardDAV, Google-style DAV access, local vdir directories, and other storages so terminal applications can edit local .ics and .vcf data while servers remain in sync.

Its README summarizes the intent as doing for calendars and contacts what OfflineIMAP did for email: keep local files and remote servers synchronized while letting users choose their preferred local clients.

Project history

The pimutils/vdirsyncer repository was created on 2014-02-15. Markus Unterwaditzer's 2014 project-history post explains the motivation in the context of leaving monolithic desktop PIM applications behind and preferring command-line applications with flat-file state.

The changelog shows rapid early development through 2014 and 2015 around DAV compatibility, authentication, collection discovery, configuration format, iCloud, Baikal, ownCloud, Zimbra, Radicale, and metadata handling. In March 2016, vdirsyncer moved to the pimutils organization on GitHub, making it part of a broader command-line personal-information-management suite.

Adoption history

vdirsyncer became a core component in the pimutils ecosystem. The pimutils site describes the suite as command-line tools for contacts, calendars, and tasks, listing khal, todoman, and vdirsyncer together and noting that these programs use standards-based vdir storage for local data.

The adoption pattern is less about mass-market visibility and more about durable Unix-workflow integration. Users pair vdirsyncer with khal for calendars, khard or other vCard tools for contacts, todoman for tasks, cron or systemd timers for periodic sync, and CalDAV/CardDAV servers such as Nextcloud, Radicale, Baikal, iCloud, FastMail, or Google endpoints.

How it is used

A typical setup defines storage sections and pair sections in the config file, runs vdirsyncer discover to discover remote collections, then runs vdirsyncer sync to move changed items. The official tutorial explains that synchronized address books become local folders containing one .vcf file per contact, and calendar sync follows the same pattern with .ics files.

Conflict handling is explicit rather than magical. The tutorial documents conflict-resolution choices: stop with an error by default, choose one side, or run a merge command supplied by the user.

Why package nerds care

vdirsyncer is significant because it turns personal information management into a standards-and-files problem. The local vdir layout lets unrelated applications cooperate over ordinary files, while vdirsyncer handles the messy CalDAV/CardDAV protocol edge cases.

For package maintainers, it is also a classic Python CLI maintenance story: the changelog records changing Python support windows, dependency changes, packaging guidelines, and distribution-facing fixes. The later pimsync work in the same ecosystem reflects accumulated lessons about modularity and packaging pain.

Timeline

2014-06-12: Version 0.2.0 was released, adopting PyPI's icalendar package and requests-toolbelt.
2014-12-31: Version 0.4.0 rewrote collection discovery and added XDG config lookup.
2016-03-22: Version 0.9.3 moved the project to the pimutils GitHub organization.
2016-09-29: Version 0.13.0 dropped Python 2 support.
2017-06-02: Version 0.16.0 improved DAV discovery and Google storage behavior.
2020-06-09: Version 0.16.8 was released for newer Python compatibility and marked final support for Python 3.5 and 3.6.
2024-2025: pimutils published vdirsyncer 2.0 alpha/beta news and pimsync successor work.

Related projects

vdirsyncer is closely related to khal, khard, todoman, pimsync, and the vdir storage format. It also occupies the same conceptual space as OfflineIMAP: a synchronizer that keeps server-backed personal data available as local files.
