WunderBase – Serverless OSS database on top of SQLite, Firecracker

In plain words

WunderBase is a serverless open-source database built on top of SQLite and Firecracker. It is designed for developers who need a lightweight database solution without managing infrastructure. The product runs SQLite in isolated virtual machines, combining the simplicity of SQLite with serverless scalability. It targets development teams looking for an alternative to traditional database management systems.

For current product information, see WunderGraph Cosmo Today we're happy to announce the open source release of WunderBase, a Serverless Database with a GraphQL API on top of SQLite, Firecracker/Fly machines, and Prisma. It's embarrassingly simple, but powerful, as the codebase is less than 400 lines of Go. WunderBase is built on top of Fly machines, which is a REST API that allows you to run virtual machines in seconds. What's special about machines is that they can sleep when an application exits with a zero exit code. When you send a request to…from wundergraph.com

  We just launched Outerbase Studio, the open-source version of our core database offering. It works in your browser or as a desktop app and supports MySQL, PostgreSQL, and SQLite.

Why we built it: We wanted to share the core Outerbase experience with the developer community as a free, open-source tool. It’s simple, fast, and removes the barriers…

  Cozo – new Graph DB with Datalog, embedded like SQLite2022 · github.com · ▲425

  Hi HN, I have been making this Cozo database since half a year ago, and now it is ready for public release. My initial motivation is that I want a graph database. Lightweight and easy to use, like SQLite. Powerful and performant, like Postgres. I found none of the existing solutions good enough. Deciding to roll my own, I need to choose a query language. I am familiar with Cypher but consider it not much of an improvement over CTE in SQL (Cypher is sometimes notationally more convenient, but not more expressive). I like Gremlin but would prefer something more declarative. Experimentations…

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I'm building an open-source Amazon▲1,335

  A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
