travelynx is a check-in and trip-logging service for public transport users, covering scenarios in Germany, Austria, Switzerland, Luxembourg, Ireland, Denmark, parts of the United States, and more. Users can record journeys by bus, tram, train, and other modes, view maps and real-time data, and see statistics such as time spent on public transport and delays over a given period. The project was inspired by Träwelling and is positioned as a hobby project.
Its core capabilities include recording scheduled and real-time departure/arrival times, sharing current and past trips, trip statistics, assistance with passenger rights forms, and optional public travel status and history. The system integrates OpenStreetMap for map display and uses transport data backends such as DBRIS, EFA, HAFAS, IRIS, and MOTIS. Developer support is fairly complete, with APIs for status queries, Check-in/Checkout/Undo, and historical trip imports, as well as Webhooks for passing status updates to other applications.
travelynx is available for free, with no commercial plans or paid versions found. Operating costs are about 10 euros per month and are personally funded. The source code is open under AGPL v3, and users can download it and self-host it. In terms of permissions, it leans toward personal/social use: trip visibility can be set to private, unlisted, followers, travelynx, or public, and it supports follows, follow requests, blocking, and related relationships. However, it does not offer enterprise organizations, role-based permissions, approval workflows, or other team collaboration capabilities.
The privacy statement is relatively transparent: logs are kept for two weeks, IP addresses are not stored, account data is hosted on servers in Germany and the Netherlands within the EU, passwords are hashed with bcrypt, and users can view, correct, or delete trips or accounts. Accounts are automatically deleted after one year of inactivity. Security measures include routine security updates and SSH private key login, but disk encryption is not currently used. More importantly, the official documentation explicitly states that there is no availability guarantee, and feature requests or issue handling depend on the maintainer’s time and motivation. This makes it unsuitable for enterprise scenarios that depend on an SLA.
Its strengths are that it is free, open source, API-friendly, and detailed in its privacy disclosures, making it suitable for public transport enthusiasts, commuters who want to log their trips, and developers interested in self-hosting. Its drawbacks are clear Europe-centric coverage and a lack of enterprise-grade permissions, support, compliance certifications, and stability commitments. The provided text does not indicate accessibility from China, and its transport data is not primarily aimed at China. Local alternatives could include general map timeline features, personal travel logging tools, or self-hosted open-source logging solutions.
