epidemics vs nanonext
A side-by-side editorial comparison of epidemics and nanonext — release velocity, themes, recent moves, and the top alternatives to consider.
epidemics vs nanonext: at a glance
What is epidemics?
epidemics swapped its C++ engine for odin — and quietly inverted how contact matrices must be passed.
epidemics ships composable compartmental model structures — default SEIR-V, Vacamole, diphtheria and Ebola — with classes for populations, interventions and vaccination campaigns. After more than two years without a release, 0.5.0 landed in July 2026 carrying both an engine migration and a breaking input-convention change. Maintainership moved to a new lead back in 0.4.0.
What is nanonext?
nanonext keeps shrinking its build requirements while adding messaging primitives.
The R binding to NNG ships roughly monthly. Since February the package added an HTTP server that can run synchronously or through the later event loop, a zero-copy device forwarder for building brokers and proxies, and support for pthread-enabled WebAssembly targets. Send operations now move the buffer straight into the NNG message, halving peak memory on serialized sends.

epidemics swapped its C++ engine for odin — and quietly inverted how contact matrices must be passed.
◆ Current state
epidemics ships composable compartmental model structures — default SEIR-V, Vacamole, diphtheria and Ebola — with classes for populations, interventions and vaccination campaigns. After more than two years without a release, 0.5.0 landed in July 2026 carrying both an engine migration and a breaking input-convention change. Maintainership moved to a new lead back in 0.4.0.
◆ Where it's heading
The package's history is a sequence of deliberate breaking releases: 0.2.0 renamed every model function and vectorised the ODE models, 0.3.0 restructured the Ebola model into two levels and made replicates the default, and 0.5.0 rewrites the compiled core. The direction is toward a smaller, more declarative model definition layer with the numerical work delegated to a dedicated tool.
◆ Prediction
With the default, Vacamole and diphtheria systems now declared in odin, the Ebola model is the obvious remaining candidate for the same treatment.
nanonext
2.5ANALYTICS
nanonext keeps shrinking its build requirements while adding messaging primitives.
◆ Current state
The R binding to NNG ships roughly monthly. Since February the package added an HTTP server that can run synchronously or through the later event loop, a zero-copy device forwarder for building brokers and proxies, and support for pthread-enabled WebAssembly targets. Send operations now move the buffer straight into the NNG message, halving peak memory on serialized sends.
◆ Where it's heading
Two directions run in parallel. One is making the package installable anywhere — the build-time cmake dependency is gone, so compiling bundled NNG and Mbed TLS needs only a C compiler, and WebAssembly targets are supported. The other is raising the ceiling on what can be built on top: device_aio() for message forwarding, an HTTP and WebSocket server with a content map, and stream buffer control. Bug fixes in recent releases concentrate on memory safety in the bundled C sources.
◆ Prediction
Given the pace and the tight coupling declared in each release, expect the next version to track a mirai requirement and continue hardening the HTTP server paths that the last two releases have been leaking memory in.

logrx
A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.
lobstr
R's object inspector is losing its view of the internals as CRAN closes off the private C API.
GSODR
A weather-station data client that broke one return type to hand back distances instead of bare IDs.
giscoR
giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
