epinowcast vs reproducible: at a glance
What is epinowcast?
epinowcast added Gaussian processes to its formula interface and made the sampler twice as fast
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
What is reproducible?
reproducible added a windowed read path so remote GeoTiffs never fully download
reproducible provides caching and input-preparation tooling for R workflows, with prepInputs() as the central entry point for fetching, cropping and post-processing spatial data. Only two releases are on record here, both from May 2026 and two days apart: a feature release followed immediately by a CRAN-triggered patch.

◆ Current state
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
◆ Where it's heading
The package is converging on a general formula-driven latent process toolkit rather than a single nowcasting model. rw() and arima() were joined in 0.7.0 by gp(), a Hilbert-space reduced-rank Gaussian process placeable on any module's linear predictor with selectable kernels and an integration order matching arima()'s d. Alongside it, the fixed-effects design and integrated residuals are now centred against the module intercept, which the notes report roughly doubles sampling speed on a weekly random-walk growth model.
◆ Prediction
With CRAN preparation done in 0.6.0 and the model surface substantially widened in 0.7.0, the next release is likely a CRAN submission plus consolidation of the gp() kernels. The release notes repeatedly benchmark against EpiNow2's behaviour, suggesting continued convergence between the two codebases.

◆ Current state
reproducible provides caching and input-preparation tooling for R workflows, with prepInputs() as the central entry point for fetching, cropping and post-processing spatial data. Only two releases are on record here, both from May 2026 and two days apart: a feature release followed immediately by a CRAN-triggered patch.
◆ Where it's heading
3.1.0 adds prepInputsCOG, a fast path inside prepInputs for remote tiled GeoTiffs including Cloud Optimized GeoTiffs. When the URL is HTTP(S) and any of to, cropTo or maskTo is supplied, only the spatial window of interest is fetched through GDAL's /vsicurl/, and the resulting windowed SpatRaster continues through the normal post-processing pipeline. The same release renames the inputPaths options to the destinationPathShared family with backwards-compatible aliases and a deprecation message, and lets alsoExtract accept regex patterns.
◆ Prediction
The COG path being opt-out via options(reproducible.useCOG = FALSE) suggests confidence in it as a default, so wider application across the prepInputs family is the plausible next step. Two entries is a thin base for predicting cadence.

Frequently asked questions
What is the difference between epinowcast and reproducible?
Both compete on the same themes — r — within Analytics. epinowcast and reproducible are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is epinowcast better than reproducible?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. epinowcast and reproducible are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
