CryptPad vs Syncthing
A side-by-side editorial comparison of CryptPad and Syncthing — release velocity, themes, recent moves, and the top alternatives to consider.
CryptPad vs Syncthing: at a glance
What is CryptPad?
CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.
CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.
What is Syncthing?
Syncthing 2.1.7 hits a fourth release candidate as fixes move from protocol to sync logic.
Syncthing's 2.1 line added device and folder groups, HTTP CONNECT proxies, optional block indexing and configurable GUI sessions. Every tracked entry since then is a patch release candidate. 2.1.6 took four RCs, and 2.1.7 is now on rc.4, which adds sync-model fixes for metadata shortcuts, parent ownership and receive-only folders on top of rc.3's protocol validation.

CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.
◆ Current state
CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.
◆ Where it's heading
The office suite is the recurring pressure point: nearly every release since 2025 carries OnlyOffice corruption, history or pinning fixes, and the Euro-Office swap is the team taking ownership of that dependency. Splitting the server into its own package points toward easier self-hosting and embedding, which matches the openDesk integration builds and Integration API work seen earlier in the year.
◆ Prediction
Expect another fix release within weeks addressing new-server and Euro-Office edge cases, then a winter feature release built on the new server. Whether the server package gets third-party adoption is not visible from these entries.
Syncthing
5.0COLLAB
Syncthing 2.1.7 hits a fourth release candidate as fixes move from protocol to sync logic.
◆ Current state
Syncthing's 2.1 line added device and folder groups, HTTP CONNECT proxies, optional block indexing and configurable GUI sessions. Every tracked entry since then is a patch release candidate. 2.1.6 took four RCs, and 2.1.7 is now on rc.4, which adds sync-model fixes for metadata shortcuts, parent ownership and receive-only folders on top of rc.3's protocol validation.
◆ Where it's heading
The project is stabilising the SQLite backend that came with 2.x and tightening the network protocol, and rc.4 extends that to correctness fixes in the sync model itself. Releases go through several RCs before going stable, roughly every two to three weeks.
◆ Prediction
Expect 2.1.7 stable after rc.4, followed by more 2.1.x patches on SQLite and sync correctness. The entries don't show what 2.2 will bring.
