Benchmark multiple LLMs to compare quality, speed, and cost
Yet another prompt benchmarking UI when Promptfoo and LangSmith already exist.

Telemetry analysis for track drivers without the pro race-engineering setup cost.
Track-day drivers and amateur motorsport enthusiasts
Harry's Lap Timer · TrackAddict · RaceStudio
It is a mobile app and web analyzer for track-day drivers - the idea is to help drivers record their sessions, verify lap times, compare laps and sectors, and understand where they are gaining or losing time using GPS, OBD II, video and other telemetry sources.
Last week, 11 people used Vetkuro at Słomczyn, a track near Warsaw, Poland, and recorded more than 40 sessions. I later learned that they had downloaded the app through word of mouth.
Professionally, I’m a software developer with 15+ years of experience, although in recent years I’ve become more of a manager than a full-time developer. Motorsport is my passion. I go to the track several times a year, and, as often happens with side projects, I started building Vetkuro for myself, partly out of curiosity, partly because I wanted to improve, and partly because I wanted to build something in a domain I care about.
The app is intended for drivers of cars, motorcycles, go-karts and similar vehicles who want to check their results, improve their driving, or simply compete with others.
The product is still early and my backlog is still substantial. It cost me a lot mentally to release it in a state that was not as polished as I wanted. But after three years of working on it after hours, keeping it in a drawer any longer felt worse than releasing something imperfect.
I’m open to any feedback/questions (especially from people who go to the track) product, technical, UX, positioning, or criticism.
regards, Pawel

Reverse-engineered USB protocol in 24hrs; $30 BLE sniffer now works on Linux.
Single-binary speed plus an indexed local DB, terminal heatmaps/graphs and one-command extractors make for a very practical tool when you need answers now. It also bundles unexpected extras — SIGMA rule checks, TF‑IDF and anomaly/AI commands — so it blurs the line between fast grep-replacements and lightweight local analytics. The space is crowded, but the combination of indexing + built-in analytics in a cross-platform Go CLI is a neat, well-realized approach.
Native macOS menu bar for live F1 timing when browser tabs eat your RAM.
Crypto pair comparison with 52-week percentile context, but Coingecko + spreadsheet already do this.
The site weaponizes a compact set of benchmarks — throughput, RAM, cold-start, F1 score and install footprint — and even publishes raw JSON on GitHub, which makes it immediately useful for teams comparing ingestion options. Kreuzberg's Rust implementation posts jaw-dropping numbers against common tools; that's interesting, but the page leaves out crucial reproducibility details (datasets, seed runs, environment configs) you'd want before trusting the magnitude of those gaps.
