A side-by-side editorial comparison of Komga and Zoho Sign — release velocity, themes, recent moves, and the top alternatives to consider.
Komga vs Zoho Sign: 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 Zoho Sign?
Zoho Sign is wiring signatures into agents and into every country's stamp law.
Zoho Sign is executing on two fronts that rarely appear together. One is jurisdictional depth: e-Stamping across India, Nafath in Saudi Arabia, legally binding signing for Colombia, and signer identity verification covering more than 200 countries through Didit and Stripe. The other is workflow surface area — a SharePoint integration, a native Windows app, a sandbox for testing signature flows, and delegated signing. As of this month, an MCP integration puts the whole thing behind an AI agent.

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.
Zoho Sign
6.3COLLAB
Zoho Sign is wiring signatures into agents and into every country's stamp law.
◆ Current state
Zoho Sign is executing on two fronts that rarely appear together. One is jurisdictional depth: e-Stamping across India, Nafath in Saudi Arabia, legally binding signing for Colombia, and signer identity verification covering more than 200 countries through Didit and Stripe. The other is workflow surface area — a SharePoint integration, a native Windows app, a sandbox for testing signature flows, and delegated signing. As of this month, an MCP integration puts the whole thing behind an AI agent.
◆ Where it's heading
The compliance work is the moat and the integration work is the distribution, and Zoho Sign is now adding a third layer where the initiator is an agent rather than a person. Each regional launch makes Zoho Sign the default for a market where global competitors have to build local stamp-duty or identity plumbing they may not prioritize. The MCP move suggests signature requests are being repositioned as a step inside automated workflows rather than a destination app someone opens.
◆ Prediction
Expect the country-by-country compliance expansion to continue at its steady pace, with agent-initiated signing pushed deeper into Zoho's own suite so contract flows in CRM and HR can request and track signatures without a human sending them.
