Rocket.Chat vs Komga
A side-by-side editorial comparison of Rocket.Chat and Komga — release velocity, themes, recent moves, and the top alternatives to consider.
Rocket.Chat vs Komga: at a glance
What is Rocket.Chat?
The 8.7 train front-loaded AI Search and server-side OAuth, then coasted through five quiet RCs.
Rocket.Chat is mid-flight on the 8.7.0 release-candidate train, and effectively all of the substance landed in rc.0: AI Search with semantic message results and optional OpenAI-compatible answers, a rebuilt server-side OAuth flow with PKCE and state validation, FIPS-compliant crypto across the monolith and every microservice, and an alternative Node runtime for the Apps Engine. The five candidates since then are version bumps plus a single audio-seek fix. The 8.6 line ahead of it followed the same shape, with a unified presence engine appearing in its own rc.0.
What is Komga?
A mature media server whose releases are format edge cases and Kobo plumbing.
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.

Rocket.Chat
6.3COLLAB
The 8.7 train front-loaded AI Search and server-side OAuth, then coasted through five quiet RCs.
◆ Current state
Rocket.Chat is mid-flight on the 8.7.0 release-candidate train, and effectively all of the substance landed in rc.0: AI Search with semantic message results and optional OpenAI-compatible answers, a rebuilt server-side OAuth flow with PKCE and state validation, FIPS-compliant crypto across the monolith and every microservice, and an alternative Node runtime for the Apps Engine. The five candidates since then are version bumps plus a single audio-seek fix. The 8.6 line ahead of it followed the same shape, with a unified presence engine appearing in its own rc.0.
◆ Where it's heading
Two threads are pulling in the same direction: making self-hosted Rocket.Chat defensible in regulated environments, and giving it an AI surface of its own. FIPS mode is gated behind a new licensed module, and AI Search arrives with an 'AI Center' configuration area rather than as a bolted-on setting — both signal features built to be sold into compliance-bound buyers. The OAuth rework moving token handling fully server-side, behind an opt-in Accounts_OAuth_Use_Modern_Flow toggle, is the same instinct applied to authentication.
◆ Prediction
Expect 8.7.0 to reach GA with the rc.0 feature set essentially unchanged, since five candidates have added no new capability. The AI Center is the thing to watch: it was introduced as configuration scaffolding, which usually means more AI features are queued to plug into it.
Komga
0.0COLLAB
A mature media server whose releases are format edge cases and Kobo plumbing.
◆ Current state
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.
◆ Where it's heading
The work concentrates where a self-hosted library server actually breaks: malformed EPUBs, archive formats readers assume will just open, and the sync protocols third-party devices speak. Kobo integration keeps taking attention — content restriction enforcement, proxying raw request bodies to the Kobo store — which suggests e-reader compatibility is where the user pressure sits. Translation batches from Weblate appear in most releases.
◆ Prediction
Expect more format-tolerance work on EPUB and archive handling, with the Kobo and KOReader integrations continuing to absorb the fixes that a mature library server accumulates.
