What is FastSync?

FastSync is a Rust CLI for mirroring folders locally or over the network using one-shot QUIC sessions with a 6-digit code. It scans source and target, copies only changed files via metadata checks and BLAKE3 hashes, and supports fast delete folder ops with dry-runs to preview plans. Users get blazing syncs for large dirs, safe overwrites via temp files, and JSON summaries for scripts.

Why is it gaining traction?

Rust delivers native speed with bounded concurrency, outpacing rsync or naive cp for big folders, while BLAKE3 enables quick content diffs without full rescans. Network mode skips SSH/SCP setup for fast folder upload handoffs, and safety defaults—no auto-deletes, atomic writes—build trust for prod caches or backups. Devs dig the clear progress bars and strict mode for paranoid syncs.

Who should use this?

DevOps folks mirroring build artifacts or GitHub Actions caches across machines. Teams needing fast folder eraser for temp dirs or quick shares without cloud storage. Rust fans wanting a drop-in for rsync in scripts, especially with fast folder size previews via dry-runs.

Verdict

Grab it via cargo install for local/network syncs if rsync feels clunky—docs shine, CLI is intuitive. At 10 stars and 1.0% credibility, it's early (v0.9), so test on non-crit data first; maturity lags but core is solid.
