Resilio Sync Alternative for Windows Offices (2026)

What Resilio Sync Is

Resilio Sync (formerly BitTorrent Sync) is a peer-to-peer folder synchronisation tool. It keeps designated folders identical across multiple machines using BitTorrent-style transfer, with no cloud server in the middle. It scales well to large datasets and across sites, and has free and paid tiers.

It is genuinely good at what it does. People look for an alternative for specific reasons: cost at the paid tiers, wanting open-source, finding folder-sync heavier than they need, or simply wanting something simpler for an all-Windows office that mostly needs to move files rather than continuously mirror them.

First, the Key Distinction: Sync vs Transfer

This decides everything:

• Sync (Resilio, Syncthing) keeps folders continuously identical across machines. Great for "every PC must always have the latest version of this folder."
• Transfer (Oxolan, LocalSend) sends a file or folder to another machine on demand. Great for "send this to that person now."

Many offices adopt Resilio for what is actually a transfer need, then find continuous sync is more machinery than the job requires. Get this right before choosing — the P2P vs cloud guide and the LAN file sharing guide frame it fully.

The Alternatives

If you need continuous sync: Syncthing

Syncthing is the leading free, open-source, no-cloud sync tool — the closest like-for-like Resilio alternative. Same model (continuous P2P folder sync), no licensing cost, active development. More initial setup than Resilio's polish, but no paid tier.

If you actually need transfer: Oxolan

If, on reflection, the office need is "move files between Windows PCs fast and reliably," a transfer tool is simpler and removes sync-conflict management entirely. Oxolan auto-discovers every Windows PC, transfers at full LAN speed, encrypted, no cloud, with file locking to prevent overwrite collisions and commercial support. About two minutes of setup per PC.

If you need cross-platform transfer: LocalSend

Free, open-source, cross-platform send-to-device. Good when devices are mixed and the need is ad-hoc rather than continuous sync.

Recommendation

• You genuinely need continuous folder sync, free: Syncthing is the direct Resilio alternative.
• You need large-scale, multi-site sync with vendor support: Resilio's paid tier may still be the right tool — don't switch for its own sake.
• Your real need is fast Windows-to-Windows transfer, not sync: Oxolan is simpler and avoids sync-conflict overhead.
• Mixed devices, ad-hoc: LocalSend.
