Jupiter vs xh

Jupiter is an open-source Learning Record Store (LRS) for collecting learning activity data using the xAPI and Caliper specifications. Its repository ingests Experience API and Caliper API payloads, and the maker describes it as scalable and fault tolerant. Jupiter includes Metis, an open-source interface for constructing queries and reviewing metrics. Metis presents results as tables or visualizations, exports them in multiple formats, and monitors cluster health with notices about network or hardware failures. The software can be self-hosted. Transcordia also offers Jove, a hosted LRS built on Amazon Web Services and powered by Jupiter; the maker says it can handle tens of thousands of learning events per second. Jove costs nothing for up to 1 million events per year. Above that allowance, the listed price is $1 a month for each 10,000 events per month. The repository identifies an MIT license, and the maker welcomes coding contributions and pull requests. Its stated audience includes educational institutions and research organizations.

xh is a free command-line tool for sending HTTP requests, with a focus on improved performance. It uses HTTPie's request-item syntax for setting headers, request bodies, and query strings. It supports JSON and form data, multipart requests, raw data, and request bodies read from standard input or a file. Responses can be pretty-printed, limited to headers or body output, and saved or downloaded to a file. Authentication options include basic, bearer, and digest. The README lists HTTP/2 support, while the current Cargo manifest has an optional HTTP/3 feature. The --curl flag translates a request into a curl command. Security options include TLS version selection, certificate verification settings, and client-side certificates. Prebuilt binaries are provided for Linux, macOS, and Windows, with package-manager installation instructions for those systems and Android. xh is distributed under the MIT License and has a free plan priced at free. It can use HTTPie compatibility mode when invoked as http or https, or when XH_HTTPIE_COMPAT_MODE is set. The README notes that some HTTPie features are not implemented, there is no plugin system, and its documentation is worse than HTTPie's.
