ADL Open Source LRS review
A focused, self-hosted xAPI 2.0 LRS for small deployments and proof-of-concept work.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ADL Open Source LRS is a self-hosted learning record store for collecting, storing, and retrieving learning data through xAPI. Maintained by Advanced Distributed Learning and distributed under the Apache License 2.0, it is aimed at developers and small teams that want an open implementation rather than a managed service. The project supports xAPI 2.0 and exposes statement, agent, activity, profile, state, and about resources. Its API-based record export fits applications that need direct access to learning records.
Deployment is centered on Docker Compose, with PostgreSQL-backed statement storage. Authentication options include HTTP Basic Authentication and optional OAuth 1.0 authentication. This gives technical teams a defined path for running the LRS and connecting it to systems that can send or retrieve xAPI statements. The feature set stays focused on the core LRS role: storing and retrieving statements, managing related xAPI resources, and providing a self-hosted foundation for experimentation or a small production footprint. Teams should expect to handle deployment and infrastructure decisions themselves.
ADL Open Source LRS is most suitable for developers who need a simple open LRS, control over deployment, and a focused xAPI 2.0 implementation. It is less suitable for organizations seeking a managed platform, broad verified integrations, or a deployment intended for many users. The project is positioned for a small number of users and proof-of-concept work, so teams with larger operational requirements should assess whether its narrow scope matches their environment before adopting it.
