Vector search just got a major upgrade in Harper 5.3. 🚀 ⚡ Up to 6.5× higher throughput vs. Harper 5.2 ⚡ 1.6–2.3× higher throughput vs. PostgreSQL + pgvector in our 200K-vector benchmark Native Rust HNSW. No separate vector DB required. www.harper.fast/resources/na...

9/9/26 → localhost:9926 Coincidence? Technically, yes. But it’s also Harper Day, our extremely legitimate, definitely-not-made-up holiday. This is your sign to build something with Harper. github.com/HarperFast/h...

Built a live sports scoring app where the DB is the MQTT broker. No separate broker, no glue code, in-process ingest with real server-side timings shown on screen. Powered by Harper.

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. www.harper.fast/resources/th...

🚀 Harper 5.2 is available now! Get 5–8× faster warm reads, more predictable performance under heavy writes, and more throughput per node—with fewer systems to manage. See what’s new: www.harper.fast/resources/ha...

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: www.harper.fast/resources/fi... #SoftwareArchitecture

Harper has been named a Sample Vendor in the Gartner® Hype Cycle™ for Digital Commerce, 2026 in the Front-End Cloud category. We believe the next evolution of front-end cloud is about what the runtime can do. www.harper.fast/resources/sa...

The citizen developer era is here, but the real question is whether AI-built apps can actually run inside the enterprise. Stephen Goldberg explains why Harper’s unified runtime, built-in governance, and deployment flexibility make it the right foundation for what comes next. buff.ly/Le96WYM

Everyone is building agents on Harper right now. Jeff Darnton shares one strategy for coding agents that plan, build, QA, and review in parallel—with humans in control. Harper gives agents fewer systems to understand. buff.ly/qnD22Li

The right way to build an agent should be the easy way to build an agent. On most stacks, it isn't. Six vendors, six failure modes, six bills. Agents on Harper: a practical guide for teams shipping production agents in 2026. cdn.prod.website-files.com/68bf31b0ba94...

We’re going LIVE to build the ultimate river flow forecasting app. We're fusing live USGS stream gauges + snowpack data with an AI agent to predict flows based on historic records. We're also building a personal river log feature! 📝🤖 buff.ly/0MDNz4J

New from Harper: rocksdb-js. → Full transaction support → Lazy range iteration → TypeScript API → Prebuilt binaries → Built-in transaction log A ground-up open source RocksDB binding for Node.js. Huge thanks to @chrisbarber.dev. www.harper.fast/resources/ne...

Harper 5.0 is open source. The future of software, especially with AI agents, is a unified runtime, not a fragmented stack. Fewer layers. Better reasoning. Faster path to production. Full story ↓ buff.ly/ErGcc7t #Harper5 #OpenSource

Harper 5.0 is live. Our core runtime is now fully open source (Apache 2.0), with Harper Pro source-available under ELv2. Now with RocksDB + LMDB support. One platform for database, cache, messaging, and app logic—built for performance and scale. Read more: hackernoon.com/harper-launc...

🚀 New podcast episode with Daniel Roe, lead of the Nuxt framework. We discuss Nuxt 3, 4, the upcoming Nuxt 5, open-source leadership, and what teams should know before upgrading their apps. If you're building with Vue or Nuxt, this is a must-watch. 🎧 Watch now buff.ly/VTZo5MF #Nuxt #VueJS

Most AI agents spend more time talking to LLMs than they need to. The fix isn't a smarter model. It's a smarter runtime. Semantic caching on Harper: same question twice? Served from the vector index. $0 LLM cost. Sub-50ms. buff.ly/fGPaA3V

From pro drummer to open source maintainer. Trezy shares his path into software engineering, work on PixiJS, thoughts on AT Protocol + Bluesky, and why data sovereignty matters for devs. Great insights for builders 👇 www.harper.fast/resources/in... #OpenSource #GameDev #ATProtocol

Your tech stack wasn't built for AI coding agents. A unified runtime was. Start every project with npm create harper@latest #aicodingagent #claudecode #agenticengineering #unifiedruntime #harperdb #fullstackdev #devtools #vibecoding

What if the toughest part of agentic engineering wasn’t the model, but deployment? With Harper’s unified runtime and declarative design, AI goes from idea to live system without the human wiring. The last-mile problem is solved. 👇 www.linkedin.com/pulse/last-m...

The build-your-own era is here. In 3 days, an AI ops assistant replaced $2400/month in SaaS for under $100/month. AI thrives on declarative backends (config.yaml, schema.graphql, resource.js). That's Harper. Build > Buy. buff.ly/QrJMnQd #VibeCoding #AgenticAI

Open source doesn’t maintain itself. We talked with Jordan Harband (@LJHarb), TC39 member, NVM maintainer, and 500+ NPM packages, about JavaScript standards, dependency security, and the realities of OSS. buff.ly/GlXr9pz #OpenSource #JavaScript #WebDevelopment
