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 Papermark?
Papermark turns data rooms into M&A-grade workflow tools with groups, staged uploads, and stronger AI Q&A.
Papermark is an open-source secure-document-sharing platform that has spent the recent quarter building out the data room into something that can credibly run a due-diligence process. New visitor groups let admins manage permissions across cohorts of buyers, advisors, or counsel; data room upload visibility supports staged document releases; AI agents got faster and more accurate for cross-document Q&A; and notification settings became granular per-link and per-event.

Komga

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.
Papermark
0.0COLLAB
Papermark turns data rooms into M&A-grade workflow tools with groups, staged uploads, and stronger AI Q&A.
◆ Current state
Papermark is an open-source secure-document-sharing platform that has spent the recent quarter building out the data room into something that can credibly run a due-diligence process. New visitor groups let admins manage permissions across cohorts of buyers, advisors, or counsel; data room upload visibility supports staged document releases; AI agents got faster and more accurate for cross-document Q&A; and notification settings became granular per-link and per-event.
◆ Where it's heading
The shape of recent releases is consistent: each one removes an operational paper-cut that would otherwise force a deal-room admin into spreadsheets or manual workflows. Papermark is positioning the data room as the system of record for M&A and fundraising flows rather than just a sharing surface — with the AI agents serving as the Q&A interface that makes a sprawling room actually navigable for visitors.
◆ Prediction
Expect more workflow ergonomics on top of visitor groups (group-level analytics, group-based watermarking, automated room provisioning per deal stage) and continued AI investment focused on cross-document reasoning, since that's where the data room's value compounds versus single-document sharing.
