Stephan Ewen (@StephanEwen) is the co-founder of Restate, the open-source workflow-as-code engine. Restate is lightweight, simple, and provides durable execution. Before Restate, Stephan co-created Apache Flink, the open-source stream processing framework. Lessons learned from Flink have heavily influenced the development of Restate, although Stephan says they have exact opposite use cases.

Eyal Solomon (@EyalSolomo44643) is the CEO and co-founder of Lunar, an open-source platform which bills itself as the “first reverse API gateway.” Lunar allows engineering teams to monitor, manage, and optimize API consumption. According to Eyal, it’s very easy to integrate with APIs, but difficult to keep them maintained, and there was a clear need for a generic solution to control and scale every API consumed in production.

After his first child was born, Matt Wonlaw (@tantaman) imagined giving his son life advice. What kind of life did he want his kid to lead? At the time, he was working for Facebook, and he decided that his own life needed a change in direction. So Matt started vlcn, aka Vulcan Labs, a research company that develops open-source projects like CR-SQLite and Materialite. vlcn has an unusual business model – Matt receives donations and sponsorships from users and clients. It’s all part of his mission to rethink the modern data stack for writing rich and complex applications.

Amplication is an open-source development platform for scalable and secure Node.js applications. It allows engineers to skip writing boilerplate code and offers the flexibility to customize and add components. Amplification was created by Yuval Hazaz (@Yuvalhazaz1), a veteran developer who determined that low-code platforms save time but restrict freedom. Instead, Amplication uses code generation to reliably and consistently build robust production‑ready backend services.

OpenBB is an open-source investment research platform created by Didier Lopes (@didier_lopes). OpenBB grew out of a project called Gamestonk Terminal that Didier began working on shortly before the Gamestop short squeeze in January 2021. Today, OpenBB has evolved into an infrastructure platform that allows users to build extensions and access financial data with automation and customization.

Ben Johnson (@benbjohnson) is the creator of Litestream and LiteFS, two open-source disaster recovery solution for SQLite. Litestream is designed to provide continuous backups for SQLite databases by streaming incremental changes, allowing for easy data recovery in the event of a server crash. LiteFS, on the other hand, is built on LiteStream but uses transactional control to focus on replication and high availability. Join us as Ben discusses the challenges and trade-offs of open source contributions and the future of databases.
