One is free and open source. The other is a paid business tool with a license on every PC. Both sync folders well. The real question is what your situation needs around the syncing — here is the honest breakdown.
🎥 GoodSync's side of this comparison is demonstrated in the video — this guide gives FreeFileSync its fair hearing too
People discover GoodSync and FreeFileSync in the same search, and the price difference makes the decision look obvious. Sometimes it is — and sometimes the free tool quietly cannot reach the server, run logged-out, or avoid re-uploading a 4 GB file for a one-line change. Both tools are honest products with loyal users. This comparison goes feature by feature, states who wins each round, and ends with a verdict by type of user rather than a fake universal winner.
The comparison in one screen — where each tool earns its keep
Price — FreeFileSyncFREE
Price — GoodSyncPAID PER PC
Cloud and server endpoints — GoodSyncWIDER
Runs logged-out as a service — GoodSyncBUILT IN
Simple two-folder jobs — bothEQUAL
👆 The one-line summary. The rounds below explain each row — including the ones where paying for GoodSync buys you nothing.
1
Round 1 — Price and Licensing, Stated Plainly
FreeFileSync is free and open source. A paid Donation Edition adds conveniences like parallel file processing, an auto-updater and portable use — a one-time donation, not a per-PC subscription
GoodSync is commercial: a trial first, then a license for each computer it runs on, with business editions priced per workstation and much higher per server
Verdict: if your need is “these two folders, on my PC,” paying for GoodSync is hard to justify. The money only starts making sense in the rounds below
2
Round 2 — Where the Files Can Live
FreeFileSync handles local folders, network shares, FTP/SFTP, Google Drive and phone storage (MTP) — a solid, practical list
GoodSync's endpoint list is simply wider: add WebDAV, OneDrive and SharePoint, Dropbox and Box, Amazon S3, Azure and Backblaze B2 — plus GoodSync Connect, direct PC-to-PC syncing across the internet with no port forwarding and no cloud in the middle
Verdict: the moment a job must end in S3, OneDrive for Business, WebDAV, or a PC in another city without network surgery, this round ends the argument
3
Round 3 — Automation and Running Unattended
FreeFileSync automates through batch jobs driven by the Windows Task Scheduler, and its companion RealTimeSync watches folders and fires a job when files change. It works — but you are assembling and maintaining the machinery
GoodSync has scheduling, real-time watching, on-connect triggers and run history inside the job itself, and in service mode its jobs keep running while nobody is logged in — the normal state of an office server at night
Verdict: home users will not feel the difference. An office that logs everyone off at 7 pm will
4
Round 4 — Big Files, Conflicts and the Details
Changed data: GoodSync can copy only the changed blocks of a large file; FreeFileSync copies the whole file again. On a 4 GB accounts or video file edited daily, that is seconds versus a full re-upload
Conflicts: both tools detect a file changed on both sides and refuse to guess silently. FreeFileSync tracks deletions and moves with its database file; GoodSync keeps its per-job state and can preserve overwritten versions in its saved folder
Support: GoodSync is a company product with official support channels; FreeFileSync is community-supported. Offices under audit or deadline usually count this as a feature

The Verdict, by Who You Are
Home user, two folders, one PC: take FreeFileSync and spend nothing. It is genuinely good at exactly this
Home user syncing a PC and a laptop across the internet: GoodSync Connect saves you the VPN and port-forwarding project — the license buys convenience, honestly
Office or server, jobs must run logged-out, endpoints include cloud and SFTP, big files change daily: GoodSync is the tool built for this list, and its per-computer price is simply the cost of that list
Switching later is painless either way — both tools work on ordinary folders, so your data is never locked inside one of them
🔴 The bias check: this guide sits under a GoodSync video, so weigh it accordingly — but the facts above are checkable on both products' own pages in five minutes. The short version survives any checking: FreeFileSync wins on price for simple jobs; GoodSync earns its money on endpoints, unattended running and block-level copying. Watch the video to see which of those you actually need.
🎥 Watch the Complete Video
Watch GoodSync demonstrated in the video — then judge it against this list with your own folders in mind.
Yes — FreeFileSync is open source and free for personal and commercial use; the Donation Edition is an optional payment for extra conveniences like parallel processing and automatic updates, not a business license requirement. Read its own site for the current feature split before deciding.
Can both tools run at the same time on one PC?
They can, but do not point both at the same pair of folders — two engines making decisions about the same files is how conflicts and confusion are manufactured. Pick one tool per folder pair. Migrating a pair from one tool to the other is safe: stop the first job, create the second, and let it Analyze before its first run.
Which one is safer against accidental deletion?
Both can propagate deletions faithfully — that is a job-design question, not a brand question. In GoodSync the safeguards are one-way backup jobs, Propagate Deletions off, and saved versions on. In FreeFileSync the equivalent is its versioning option sending replaced files to a dated folder. Whichever tool you choose, set those options before the first real run.
