Everything You Need to Build Faster

Complex storefronts can outgrow SPCC native hosting. Harper connects the systems around SFCC to speed up shopping and protect sales.

See how Harper’s unified runtime and supervised AI agents modernized a production storefront while engineers retained control of quality and releases.

Former Akamai executive brings enterprise platform expertise to Harper’s next chapter, as co-founder Stephen Goldberg continues on the board.

Explore vector index in Harper 5.3’s with benchmarks against pgvector and Harper 5.2, and the open-source Node.js package @harperfast/hnsw.

Explore how Harper brings search, embeddings, model access, and controlled AI decisions into one runtime, reducing the services around your AI application.

Build a MOP and change management application on Harper. Connect procedures, search, approvals, and execution without assembling a separate infrastructure stack.

Most real-time apps need a broker, a bridge, and a cache to keep state in sync. This is a live MQTT scoring demo on Harper, where the topic and the database record are the same write.

Cross-region latency comes from distance, not slow queries. Why centralized data paths cost you latency, uptime, and money, with a benchmark you can run.

Harper 5.2 attacks database performance on three fronts: a per-worker record cache validated through lock-free atomic version slots, isolated commit scheduling to keep database writes off the application thread, and query planner improvements that route through the shortest available data path.

Harper’s inclusion highlights a broader shift toward integrated cloud-native platforms that unify data, caching, messaging, and application logic. The article explains how Harper’s distributed runtime and managed infrastructure reduce operational complexity, improve performance, and support modern applications and AI agents that require fast, reliable access to state, events, and tools.

Reduce API latency under load with a caching alternative to Redis: an in-process cache that cut response time 100x without adding a new tier.

Harper 5.2 helps architecture and platform leaders improve performance, control infrastructure costs, secure production workloads, and reduce operational complexity by bringing faster data access, agentic capabilities, scheduling, backup, routing, and protection into one unified runtime.

Personalization is a data-delivery problem. Every architectural choice reduces to two distances: compute to user, and compute to fresh data. This piece maps five real architectures against both axes, scored on a concrete retailer workload where stale or slow data breaks the business.
