AFFiNE vs SOGo
A side-by-side editorial comparison of AFFiNE and SOGo — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs SOGo: at a glance
What is AFFiNE?
AFFiNE ships twice a day on two trains, and it is all storage plumbing and window polish.
AFFiNE publishes almost daily, but on two parallel trains — dated canary builds and v0.27.x-beta tags — that frequently carry the identical pull request. What is actually moving is infrastructure: presigned upload URLs for S3 and R2, document garbage-collection checkpointing, Obsidian import fidelity, and desktop window handling. Nothing in the last ten releases touches the editor's feature surface.
What is SOGo?
SOGo's 5.12 line has become a CVE conveyor belt while the team's attention sits on SOGo 6.
Six releases in three months, and the majority exist to fix vulnerabilities: XSS via crafted mail, SQL injection, JavaScript injection through hint and theme query parameters, impersonation when OpenID is paired with a non-matching user source, and two CVEs affecting PostgreSQL user sources. Releases 5.12.6 and 5.12.9 exist purely to undo regressions the security fixes introduced.

AFFiNE
6.3COLLAB
AFFiNE ships twice a day on two trains, and it is all storage plumbing and window polish.
◆ Current state
AFFiNE publishes almost daily, but on two parallel trains — dated canary builds and v0.27.x-beta tags — that frequently carry the identical pull request. What is actually moving is infrastructure: presigned upload URLs for S3 and R2, document garbage-collection checkpointing, Obsidian import fidelity, and desktop window handling. Nothing in the last ten releases touches the editor's feature surface.
◆ Where it's heading
The work is concentrated on self-hosting and durability rather than on anything a user sees. Storage configuration is being generalized across providers, document reconciliation is being made resumable after partial runs, and the desktop shell is collecting dock, tray, and keyboard fixes across macOS and mobile. Read together, this is a team hardening the deployment story of an existing product rather than extending it.
◆ Prediction
The 0.27.4 line looks set to reach a stable tag carrying the same blob-sync and doc-GC work already sitting in beta. The entries give no signal on editor or AI direction, so anything past that is not visible from this feed.
SOGo
0.0COLLAB
SOGo's 5.12 line has become a CVE conveyor belt while the team's attention sits on SOGo 6.
◆ Current state
Six releases in three months, and the majority exist to fix vulnerabilities: XSS via crafted mail, SQL injection, JavaScript injection through hint and theme query parameters, impersonation when OpenID is paired with a non-matching user source, and two CVEs affecting PostgreSQL user sources. Releases 5.12.6 and 5.12.9 exist purely to undo regressions the security fixes introduced.
◆ Where it's heading
Alinto declared a feature freeze on 5.12 to concentrate on SOGo 6, and the changelog reflects it — the one new capability in the window, a REST API in 5.12.2, was explicitly a pre-committed sponsored deliverable the team felt obliged to honour. What is left is a hardening cycle on a large groupware surface, with each fix carrying real regression risk into webmail and calendar.
◆ Prediction
Expect the 5.12.x line to keep producing security releases with regression follow-ups, and no new functionality until SOGo 6 surfaces.
