HarperDB: a Modern Tool for Fullstack Development

If you’re looking for a new database for your next web development project, you may be wondering which DB will work best for you and your team. While having so many options is excellent, weighing the benefits and drawbacks of each type of database can be overwhelming.

This tutorial will explain what is HarperDB and why is it better for Full-Stack Development?

What is HarperDB

HarperDB is a data management system that supports both SQL and NoSQL functionality.

It’s fully indexed, doesn’t duplicate data, and can be used on any device, from the edge to the cloud and with the addition of Custom Functions, HarperDB grew from a distributed database to a distributed application development platform. You now can host your database and server API on the same platform with full CRUD functionality.

HarperDB offers everything: NoSQL, SQL, and NewSQL.


SQL and NoSQL contribute to the industry for their individual use cases. HarperDB was designed to meet the needs of both use cases by combining the strengths of both technologies.

  • It supports both SQL and NoSQL queries.
  • It also offers access to the database instance directly inside the client-side application.

HarperDB is all about simplicity without sacrifice.

How is HarperDB Database a Game-Changer?

  • Most flexible DB on the market.
  • HarperDB is 38X faster than competitors.
  • HarperDB globally replicates the data at the speed of the internet.
  • Custom functions make it more powerful.

Its SQL/NoSQL capabilities make it a game-changer. To support complex SQL queries, most NoSQL databases use a multi-model architecture. Under the hood, a multi-model is analogous to running two separate databases. Whereas HarperDB is intended to handle both SQL and NoSQL use cases out of the box.

Data inserted into HarperDB via SQL statements or NoSQL objects is mapped to a single model.

Data is never replicated, and nothing needs to be transformed after it is inserted.

With so many databases on the market, how do you know which one is best for your specific use case or skill set?

HarperDB Database Advantages Over Others

By merging the capability of the powerful SQL, NoSQL, and NewSQL technologies on the market into a single powerful tool, HarperDB simplifies and lowers the data administration cost.

  • With SQL on JSON, users no longer have to select a database based on the structure of their data.
  • With HarperDB’s speed, flexibility, and customization, you can cut down on database maintenance time and the number of systems required to achieve your goal.
  • HarperDB enables developers with relational backgrounds to leverage their existing SQL knowledge with a database that also allows their team to leverage NoSQL from the same data model (and vice versa)
  • HarperDB Custom Functions integrate serverless functions with the underlying database, simplifying the stack and allowing you to define custom API endpoints with direct access to HarperDB core operations.
  • Custom Functions, powered by Fastify, are similar to AWS Lambda functions or Stored Procedures. Functions are low-maintenance and simple to create; define logic and choose when to execute.

HarperDB is designed for developers and technology leaders of all skill levels.
