HarperDB is a startup that focuses on highly scalable databases that handle real-time data. Harper is built on Node.js and Express with a little help from Fastify. They know where they excel and where they don't.

It's speed over accuracy. Instead of a Lifeboat badge today, we shared a relevant question: Q: How to create HarperDB table with lambda.
