Velofy Information

Velofy is an open source applied AI lab based in Delhi, India. We build software that makes AI useful in real work, and we publish the research behind it with the evidence attached. What we build: • Kestrel: our in-house CLI and harness for coding agents. One headless prompt interface across coding CLIs, with isolated parallel fan-out. • troy: a headless browser agents can actually read. DOM for structure, OCR for the pixels the DOM cannot explain. • trove: lets LLMs work over codebases far larger than their context window, plus durable engineering memory for Claude Code. • querion: a strictly read-only analyst. Ask questions in plain English and get the number, the chart, and the exact SQL behind it. • terbium: business documents in, clean rows out. It scores its own confidence and only calls a model when the algorithm cannot be sure. • curl_reap: one Python library for scraping, with browser-grade TLS, self-healing selectors, and a concurrent crawl engine. • glep: indexed search for the files coding agents work with, written in Rust. • summit.js: a signal-powered framework for composing behavior directly in HTML. CSP-safe, about 13 KB. What we research: • Small decision models: calibration, abstention, and option-order robustness, measured in our open Decision Bench. • Design engineering for AI agents: DESIGN.md, design tokens, skills, and motion.
