Komga vs Simpplr: 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 Simpplr?
Simpplr publishes the research that names the gap, then ships the product that closes it.
Simpplr's feed is mostly thought leadership with product releases embedded in it. The one release in this window is the Rewards Store, live August 10, which lets recognition given inside Simpplr be redeemed without leaving the platform. Everything around it is argument: the homepage that serves nobody because it serves everyone, frontline workers missing company updates, internal communications measurement that fails on its own terms, and a buyer's guide for the recognition category Simpplr has just entered.

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.
Simpplr
6.3COLLAB
Simpplr publishes the research that names the gap, then ships the product that closes it.
◆ Current state
Simpplr's feed is mostly thought leadership with product releases embedded in it. The one release in this window is the Rewards Store, live August 10, which lets recognition given inside Simpplr be redeemed without leaving the platform. Everything around it is argument: the homepage that serves nobody because it serves everyone, frontline workers missing company updates, internal communications measurement that fails on its own terms, and a buyer's guide for the recognition category Simpplr has just entered.
◆ Where it's heading
The pattern is consistent enough to be a strategy. Simpplr publishes research — its own State of Internal Communications report, a commissioned Forrester study — that establishes a problem in category terms, then releases the feature that answers it. Recognition fragmenting across separate tools was the argument; the Rewards Store was the answer, and the buyer's guide published a week later reframes the category around what Simpplr now owns. The homepage post is the same move one step earlier, making the case for personalization before anything has shipped against it.
◆ Prediction
The homepage argument is the one currently without a product behind it, which makes a personalized or role-aware intranet home the most likely next release in this sequence.
