How we grade them
| 1.6GPAResilio SyncWeak | 2.6GPASyncthingGood | |
|---|---|---|
| Value for money | CNo price is published, so it sits in the middle by default. | AFree software with no paid plans at all, where the rest of this category charges around $5 a month for ever. The project lives on donations, and if you want somebody to call, a separate company, Kastelo, sells commercial support. |
| Free plan and trial | FNo free plan and no free trial on record, so nothing to try before paying. | AFree outright on every operating system it supports, source code and all, with no paid tier above it holding anything back and no account to make in the first place. |
| Features | CDevice-to-device sync with an enterprise edition, with gaps the listing shows: no stated Home price or limits. | CIt does its one job completely: continuous sync of as many folders as you like, over encrypted and authenticated connections, at home or across the internet. But that one job is smaller than this category's. There's no cloud copy, no sharing links, and devices swap files only when both are online. |
| Ease of use | CNo store rating on record, and folders and peers to set up first. | DWhat you download is a command-line daemon you configure through a page in your browser, on every machine, with tray icons and file-browser integration as separate downloads. Devices do pair by ID with no network fiddling, but this is not install and go. |
| Platforms and integrations | COnly Windows and Linux builds are named on the download page, with no integrations listed. | CComputers only: Mac, Windows, Linux and several BSD systems. No phone apps are listed and the team says it has no plans to support iOS officially, so your photos and your phone are out of the picture. |
| Best for | syncing folders between your own devices | syncing your own computers with no cloud |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
