forestly vs simulist
A side-by-side editorial comparison of forestly and simulist — release velocity, themes, recent moves, and the top alternatives to consider.
forestly vs simulist: at a glance
What is forestly?
forestly built an interactive safety review tool, then taught it to produce submission-ready RTF.
forestly renders adverse-event forest plots as interactive reactable widgets — filterable by AE category, with sliders for incidence thresholds and a toggle for the risk-difference column. Version 0.1.3 added `rtf_static_forestly()` for static RTF output, and 0.1.4 has been about giving the display owner control over what reviewers see: the CSV download button, the AE filter label, and the diff toggle can each be switched off.
What is simulist?
simulist stopped simulating clean outbreaks and started simulating the mess real surveillance data arrives in.
simulist generates synthetic line list and contact-tracing data for outbreak analytics as part of the Epiverse-TRACE stack. It reached stable status in 0.6.0 and was published in JOSS alongside 0.7.0 in February 2026. Its distinguishing feature is no longer the epidemic simulation itself but the post-processing layer that degrades the output into realistic data.

◆ Current state
forestly renders adverse-event forest plots as interactive reactable widgets — filterable by AE category, with sliders for incidence thresholds and a toggle for the risk-difference column. Version 0.1.3 added `rtf_static_forestly()` for static RTF output, and 0.1.4 has been about giving the display owner control over what reviewers see: the CSV download button, the AE filter label, and the diff toggle can each be switched off.
◆ Where it's heading
The arc runs from a fixed interactive widget toward a configurable one with two output modes. Nearly every new argument in the last two releases exists to remove something from the display or relabel it, which suggests the users driving development are producing outputs for others to review under conventions they do not control. The x-axis range, column header, figure header and slider range arguments point the same way — this is a tool being fitted into standardised reporting rather than used ad hoc.
◆ Prediction
Given that the last two releases have consisted almost entirely of display-control arguments, the next is likely more of the same, applied to whichever parts of the interactive layout are still fixed.
simulist
0.0ANALYTICS
simulist stopped simulating clean outbreaks and started simulating the mess real surveillance data arrives in.
◆ Current state
simulist generates synthetic line list and contact-tracing data for outbreak analytics as part of the Epiverse-TRACE stack. It reached stable status in 0.6.0 and was published in JOSS alongside 0.7.0 in February 2026. Its distinguishing feature is no longer the epidemic simulation itself but the post-processing layer that degrades the output into realistic data.
◆ Where it's heading
The scope moved outward in two steps. 0.5.0 added truncate_linelist() and messy_linelist() to produce right-truncated snapshots and data with missingness and inconsistencies; 0.6.0 added censor_linelist() for grouping dates into intervals with a weekend-reporting effect. The simulation core has meanwhile settled — 0.7.0's changes are interface polish: weighted sex sampling and <epiparameter> objects accepted for reporting_delay.
◆ Prediction
Post-processing is where the recent work is, so further realism controls — additional reporting artefacts or interval schemes — are a likelier next step than new epidemic model structures.
