Komga vs Memos
A side-by-side editorial comparison of Komga and Memos — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:self-hosted
Komga vs Memos: at a glance
What is Komga?
Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.
What is Memos?
Memos is turning a personal note store into an agent-addressable, private-by-default service
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.

Komga is rewriting its web UI in the open, shipping the beta alongside the old one.
◆ Current state
Komga's release cadence is dominated by NextUI, a ground-up rewrite of the web interface that landed in beta with 1.26.0 and is served next to the existing UI at /next rather than replacing it. The three patch releases that followed within 48 hours were almost entirely NextUI shakedown work — scroll restoration, selection behavior, stylesheets failing to load under Tomcat. Underneath the interface work the server keeps widening format support, with rar5 handling in plain Java and solid rar4 archives earlier in the summer.
◆ Where it's heading
The project is running a long, deliberately cautious frontend migration: both UIs ship in the same binary, the feature gap is tracked publicly in an issue, and users opt in by URL. That arrangement should persist across several minor versions before the old WebUI is retired. The parallel v2 referential API suggests the rewrite is also being used to revise the server contract rather than only restyle the client.
◆ Prediction
Near-term releases should keep closing the NextUI feature gap issue by issue, with patch releases landing within days of each other. The old WebUI is unlikely to be removed before NextUI reaches parity and browser refresh stops falling back to it.

Memos is turning a personal note store into an agent-addressable, private-by-default service
◆ Current state
The release candidates in this window carry unusually heavy changes for a self-hosted note app: an embedded MCP endpoint exposing memo CRUD, comments, attachments and tags to AI clients; live updates over server-sent events; revocable share links; and a browser Web Clipper for saving pages and selections as Markdown. A parallel candidate makes instances without an explicit instance URL run in private mode and rewrites filters onto CEL timestamps.
◆ Where it's heading
Two directions are converging. One is machine access — MCP moved from a stateful server with prompts and resources to a stateless, tools-only endpoint generated from the OpenAPI schema, which is a deliberate narrowing toward something agents can call reliably. The other is defaults that assume the instance is private until an admin says otherwise. Together they reposition Memos from a personal web app to a small API-shaped service with a human UI on top.
◆ Prediction
Expect the MCP surface to stabilise against the OpenAPI schema as the source of truth and the private-by-default posture to carry into a general release, with clients that relied on prompts, resources or unprefixed tool names needing to migrate.
