jcode vs UltraFastFileSearch

jcode: jcode is a coding agent harness written in Rust, built to run dozens of agents in parallel with little RAM and near-instant startup. Agents in the same repo are coordinated by a server that notifies them of conflicting edits and lets them message each other or spawn their own swarms.; UltraFastFileSearch: UltraFastFileSearch (UFFS) is a benchmark-driven, Rust-native NTFS search engine for Windows, capable of wire-speed search across millions of records without prior indexing. It directly reads the Master File Table, builds a compact index, and maintains searchability through a background daemon, offering CLI, TUI, and API interfaces.
