Our verdict on newdle

newdle is a web-based, open-source meeting scheduling application created by CERN’s Indico team. It helps groups propose time slots, add participants by name or email address, collect availability responses, and identify suitable meeting times. Users can select slots across different days, copy slots from a previous day, keep participant lists private, and view newdles in which they participate. It is best suited to organizations that want collaborative polls with control over deployment, particularly where Exchange is already part of the workplace environment.

Its platform fit is practical but focused. newdle runs on the web and supports self-hosting, with Docker Compose available for running the application. Its Microsoft Exchange integration can fetch free-busy information from Exchange servers, helping organizers compare proposed times with calendar availability. That combination makes it relevant for Exchange-based teams, while the stated integration scope is narrower than products built around a wider calendar and collaboration ecosystem.

The product’s main strength is its deliberate focus on group scheduling polls rather than a broad meeting-management workflow. Participants can respond to proposed slots without exposing the full participant list, and organizers can reuse time slots from an earlier day. That makes newdle a sensible choice for privacy-conscious teams needing a straightforward, self-hosted polling workflow. Organizations looking for broader scheduling capabilities, multiple calendar integrations, or a less deployment-oriented setup should consider a different category fit.
