Ousia
Helps small servers handle massive enterprise traffic
What it does
Ousia gives small applications and lightweight servers the traffic-handling power of a massive enterprise infrastructure. Built in Go, it acts as an intelligent traffic funnel- automatically balancing user requests, preventing crashes with built-in circuit breakers, and speeding up data delivery Instead of paying for massive cloud overhead or fighting complex setups, Ousia gives you a zero-config, high-performance edge gateway to scale effortlessly.

- DFDuckDB for Kafka Stream ProcessingDec 2025 · sql-flow.com · ▲77
Hello Everyone! We built SQLFlow as a lightweight stream processing engine. We leverage DuckDB as the stream processing engine, which gives SQLFlow the ability to process 10's of thousands of messages a second using ~250MiB of memory! DuckDB also supports a rich ecosystem of sinks and connectors! https://sql-flow.com/docs/category/tutorials/ https://github.com/turbolytics/sql-flow We were tired of running JVM's for simple stream processing, and also of bespoke one off stream processors I would love your feedback, criticisms and/or…
- GAGonzo – A Go-based TUI for log analysis (OpenTelemetry/OTLP support)2025 · github.com · ▲74
We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!
- EJElysia JIT "Compiler", why it's one of the fastest JavaScript frameworkFeb 2026 · elysiajs.com · ▲54
Wrote a thing about what makes Elysia stand out in a performance benchmark game Basically, there's a JIT "compiler" embedded into a framework This approach has been used by ajv and TypeBox before for input validation, making it faster than other competitors Elysia basically does the same, but scales that into a full backend framework This gave Elysia an unfair advantage in the performance game, making Elysia the fastest framework on Bun runtime, but also faster than most on Node, Deno, and Cloudflare Worker as well, when using the same underlying HTTP adapter There is an escape hatch if…
- EMElestio – Managed platform for over 150 open-source software stacks2022 · ▲108
Hello Hacker News! We're Joseph, Kieran and David from elestio (https://elest.io/). We've built a platform that offers open-source software as a managed service - we take care of the OS and app updates, security, SSL, networking, backups, the whole deal. In 2009, we started deploying open-source software for websites and web apps we built, many for SMB and enterprise customers. Our process was basically: spin up VM's from a hosting provider, install the software we needed, then update it manually / when it was needed / critical, etc. Once we hit > 100…

Parallel agents, diff reviewer, and multi-model comparisons

- NW
Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
