Developers’ favorite application platform just got better. With a major upgrade to our clustering technology and numerous performance enhancements, HarperDB continues to push the boundaries of distributed applications and data management.

HarperDB 4.0 introduces advanced mesh-powered data replication technology, providing enhanced resilience, capacity, and extensibility, ensuring limitless global scale without added complexity.

Scale effortlessly from proof-of-concept to planet-scale production within minutes. It's time to go #HarperScale.

‍

What are the benefits of HarperDB 4.0?

HarperDB’s global data replication capabilities have seen significant improvements in the following areas:

Reliability: Although our previous replication engine never reported data loss, we recognized the theoretical risk in massive deployments. HarperDB 4.0 ensures guaranteed exactly-once data delivery at any scale, making it the simplest enterprise-level application development platform available.

Scalability: With virtually unlimited node capacity within a cluster, HarperDB achieves unparalleled throughput suitable for the most demanding workloads. Additionally, HarperDB significantly lowers costs at scale. Instead of costly vertical scaling through RAM upgrades, HarperDB leverages horizontal scalability. Enterprise customers have already reported substantial savings upon switching to HarperDB.

Flexibility: HarperDB is designed for broad use cases, supporting both bidirectional and unidirectional data replication, simplifying complex scenarios. Developers can effortlessly innovate with edge machine learning, near-sensor data processing, and real-time data delivery without needing additional solutions.

Simplicity: HarperDB 4.0 delivers ease of use for businesses of all sizes. Featuring our intuitive online management studio and driver-free HTTPS API, HarperDB provides straightforward tooling and integrations suitable for both beginners and experts.

‍

How does HarperDB handle clustering?

The updated clustering solution integrates distributed persistence systems for creating transaction logs, work queues, and maintaining global transparency essential for audits and troubleshooting. Additionally, advanced clustering capabilities support seamless mesh networks, extending clusters to edge locations or on-premises environments, even in limited network scenarios.

‍

How does HarperDB distribute my application AND my data?

HarperDB’s Custom Functions enable seamless packaging and deployment of applications across all nodes in a cluster via HarperDB Studio or existing CI/CD pipelines. By co-locating data and applications on the same instance, HarperDB eliminates latency between API servers and databases, ensuring improved end-user experiences and simplified infrastructure.

‍

What are some of the top use cases you see for HarperDB 4.0?

Use cases including sporadic network environments, extremely high-volume systems, and dynamic data replication scenarios are ideal for HarperDB 4.0. Despite sounding complex, HarperDB empowers development teams to leverage distributed architectures effortlessly.

Whether building the next social media giant or managing remote sensor data over unreliable connections, HarperDB 4.0 provides an industry-leading platform capable of handling virtually all enterprise workloads without escalating costs.

‍

What inspired you to build HarperDB 4.0?

Our customers inspired us. Collaborating with some of the world’s largest networks continually highlighted the inherent complexity of performant, planet-scale applications. Without infrastructure designed to handle such complexities, management and scalability become increasingly challenging and expensive. Before HarperDB, customers often spent more time configuring external platforms than coding, losing valuable momentum.

Our mission is to simplify developers' lives. We aim to offer a platform that's simple, fast, and cost-effective, enabling developers to create planet-scale experiences without infrastructure-related worries.

‍

When can I start using HarperDB 4.0?

Now! Easily deploy for free via npm and Docker and manage with HarperDB Studio. You’ll be up and running in minutes.

Who can I talk to about HarperDB 4.0?

The world’s leading team of HarperDB innovators is here to answer your questions. Also, join our growing community on Slack for fast support.

Deliver Performance and Simplicity with Distributed Microliths

Distributed microliths unify data, logic, and execution into one high-performance runtime, eliminating microservice latency and complexity. By replicating a single coherent process across regions, they deliver sub-millisecond responses, active-active resilience, and edge-level speed. Platforms like Harper prove this model reduces infrastructure, simplifies operations, and scales globally with ease.
