ADL Open Source LRS vs EscolaLMS LRS

ADL Open Source LRS stores learning data collected through the Experience API, or xAPI. The repository says this version conforms to IEEE 9274.1.1, also known as xAPI 2.0, and describes it as stable but intended for proof-of-concept use with a small number of users. It is free and distributed under the Apache License, Version 2.0.

Docker and Docker Compose are the recommended installation route. The deployment includes a Django web service using uWSGI, an nginx HTTP/HTTPS proxy, PostgreSQL, RabbitMQ, and Redis. OAuth is off by default; the project describes enabling it with the OAUTH_ENABLED setting and registering clients with the LRS. Optional webhooks can filter incoming statements and send matches to a client endpoint, and they are disabled by default. A webhook can include a secret used to send an HMAC hex digest in the X-LRS-Signature header. Celery handles activity metadata retrieval, statement voiding, and LRS hooks asynchronously. Database settings can be changed in settings.ini. The Docker guide describes an included Certbot container for obtaining a certificate for a public domain and restarting nginx to use it.

EscolaLMS LRS is a free, MIT-licensed learning record store for xAPI with cmi5 support. It is designed for API and self-hosted deployment inside a Laravel application. Installation uses PHP Composer, followed by a Laravel Artisan seeding command. The documented `/api/cmi5/courses/{id}` endpoint generates course fetch parameters, and responses under `/api/cmi5/**` should include the `x-experience-api-version: 1.0.3` header. The project describes testing this flow with a locally served cmi5 demo and links to Swagger API documentation. Escola LMS describes the backend as a Laravel headless LMS REST API. Deployment documentation covers a default Docker environment or installation as a standard Laravel application. PostgreSQL is the default database, with a MySQL initialization option. Most endpoints require authorization, which Laravel Passport can provide, and access from other domains requires suitable CORS headers. GitHub issues provide a discussion and troubleshooting channel. The project page does not state a software price beyond its open-source, free classification.
