Show HN: Ultrasync – faster indexing, search, memory, and more for coding agents (ultrasync.dev)

Ultrasync, a new tool for AI coding agents, offers a revolutionary approach to indexing and searching codebases, making it significantly faster and more efficient. It allows developers to install a server and quickly index their projects, enabling precise, sub-second queries without the overhead of traditional prompt searching. This capability not only optimizes token usage but also ensures that agents receive relevant context instantly, thus streamlining their workflows. The technical underpinnings of Ultrasync are impressive, featuring Rust-powered AOT indexing for rapid hash lookups, alongside advanced regex processing using Hyperscan for network speed performance. Persistent memory allows agents to retain valuable context from previous sessions, while auto-classification helps identify different code types without needing large language models. For teams, Ultrasync provides an enterprise-grade solution with centralized memory management, ensuring privacy and easy access to shared knowledge. This innovative tool promises to enhance developer efficiency and collaboration, making it a significant advancement in the AI/ML community.
