Ralph vs SCORM Cloud LRS

Ralph is an open-source learning analytics toolbox delivered as an LRS HTTP API server, command-line interface, and library. It runs through an API, on Linux, or as a self-hosted deployment. Ralph follows xAPI specification 1.0.3, but xAPI 2.0 is not supported. Its LRS stores data in Elasticsearch, MongoDB, or ClickHouse. The library documents connections to OVH Log Data Platform, OpenStack Swift, Amazon S3, filesystems, other LRS systems, and WebSockets. The API server supports HTTP Basic authentication and OpenID Connect over OAuth 2.0, either separately or together. Statement access can be restricted by authority, and user scopes can limit endpoints or functions; both controls are off by default. Received xAPI statements can be forwarded to other LRS servers with configurable retries and timeouts. Sentry monitors the LRS server and CLI. The CLI converts selected OpenEdX events to xAPI statements. Ralph is distributed as a Python package and Docker image under the MIT License.

SCORM Cloud LRS captures xAPI statements from online activities and learning experiences that take place in person. It has passed the ADL LRS Test Suite and accepts externally generated xAPI statements without charging by statement volume. Activity providers can be configured to forward statements to other LRSs. The SCORM Cloud player supports xAPI, cmi5, SCORM, and AICC content, and SCORM and AICC registration data can be converted into xAPI statements stored in the LRS. An API supports integrating course hosting, delivery, learner tracking, and reporting into other applications. The service runs in the cloud and is available through web and API platforms. Its free, non-time-based Trial allows 3 courses, up to 5GB of storage, and 10 resettable registrations. Paid plans range from Tester at $40 a month to Ultra at $5,000 a month, with registration allowances varying by plan. Rustici offers support by phone, email, and Knowledge Base. The company was founded in 2002 and is based in Franklin, Tennessee.
