Hope you all had a lovely January. Can't believe it's already time to share Star History's January open-source picks!</p> <p>In case you don't know, each month Star History picks out some of the most fascinating open-source projects that we share over <a href="https://twitter.com/StarHistoryHQ">@StarHistoryHQ</a>, and also try to explore the stories behind these projects.</p> <h2>Hermes</h2> <p><img src="/assets/blog/star-history-monthly-pick-202301/hermes.webp" alt="hermes"></p> <p><a href="https://github.com/hashicorp-forge/hermes">Hermes</a> is HashiCorp's newly open-sourced document management system. Previously an internal tool, it is designed to help team members write, review, approve, discover, and revoke documents. It currently supports Google Workspace, but it tops Google Docs in that you can directly request reviews, which is fantastic.</p> <p><img src="/assets/blog/star-history-monthly-pick-202301/hermes-docs.webp" alt="hermes-docs"></p> <h2>Lago</h2> <p><img src="/assets/blog/star-history-monthly-pick-202301/lago.webp" alt="lago"></p> <p><a href="https://github.com/getlago/lago">Lago</a> is a metering and usage-based billing tool that can be seen as an open-source alternative to Chargebee, Recurly, or Stripe Billing. You can deploy it yourself (the open-source version) or use their cloud version. Dealing with complex billing logic is a headache for most companies, but Lago is a convenient low-code tool that allows users to create billing metrics and plans directly using the UI or API.</p> <p><img src="/assets/blog/star-history-monthly-pick-202301/lago-billing.webp" alt="lago-billing"></p> <p>Lago was originally a no-code reverse ETL tool designed for growth teams, but their original product didn't quite fit their target audience (it turns out the no-code tool was actually used by engineers), and eventually <a href="https://www.getlago.com/blog/why-we-moved-away-from-the-no-code-reverse-etl-space">pivoted</a> to become what it is now.</p> <h2>Mafs</h2> <p><img src="/assets/blog/star-history-monthly-pick-202301/mafs.webp" alt="mafs"></p> <p><a href="https://github.com/stevenpetryk/mafs">Mafs</a> is a set of React components that can be used to create beautiful math visualizations. You can deploy it locally, and it also has a playground that can be generated directly in your browser. If I had this in high school, I'm sure I would've enjoyed Algebra more.</p> <p><img src="/assets/blog/star-history-monthly-pick-202301/mafs-playground.webp" alt="mafs-playground"></p> <h2>PRQL</h2> <p><img src="/assets/blog/star-history-monthly-pick-202301/prql.webp" alt="prql"></p> <p><a href="https://github.com/PRQL/prql">PRQL</a> is Pipelined Relational Query Language, pronounced "Prequel" (just the opposite of SQL/Sequel). Like SQL, PRQL is readable and declarative; however, unlike SQL, it supports abstract concepts such as variables and functions. Moreover, PRQL is linear: each query line converts the result of the previous line.
