We just published a new reference project for developers curious about real-time apps: the MQTT Live Scoring App, built on Harper.

Here's the short version of what makes it interesting. Score events publish over MQTT to Harper's built-in broker, no separate message queue to install or maintain. The event ingest logic runs in the same process as the database, so the timing numbers you see in the app's telemetry strip are real, measured server-side, not simulated for the demo. On top of that, the two data tables (matches and score events) get full REST APIs automatically from their schema definitions, no handler code required.

It's a compact project but it's a genuine look at what you can simplify when your database, broker, and API layer live in one platform instead of three.

Every network hop in your architecture has a cost: latency, complexity, failure modes, and dollars.

Harper takes a different approach: put the database, cache, messaging, and application runtime in one process to remove the distance.

Web personalization is a platform decision.

Architecture determines data freshness, latency, operational complexity, crawler visibility, and cost at scale.

We compared five common approaches and the tradeoffs behind each:

Everyone is building agents on Harper right now.

And the more people build, the more compelling the case gets.

Jeff Darnton’s latest article shows one strategy for turning coding agents into a real development system: dispatched agent teams that plan, build, QA, and review in parallel, with humans still owning direction.

The big unlock: Harper’s unified runtime gives agents fewer systems to understand and more room to build.

Harper enables production-grade agentic engineering by collapsing database, cache, runtime, and messaging into one process, reducing agent complexity and review burden. A multi-model dispatch workflow lets specialized agents plan, code, QA, and review in parallel while humans retain control over cri...
