git2rdata vs simulist
A side-by-side editorial comparison of git2rdata and simulist — release velocity, themes, recent moves, and the top alternatives to consider.
git2rdata vs simulist: at a glance
What is git2rdata?
git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.
git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.
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.

git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.
◆ Current state
git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.
◆ Where it's heading
The file format itself settled years ago — the last breaking change was the 0.2.0 hash rework — and development since has been about what travels alongside the data. Storage decisions that used to be implicit are becoming declarative and recorded: significant digits in 0.5.0, arbitrary attributes in 0.5.1, type conversions in 0.5.2. The other steady thread is determinism, from C-locale sorting through `icuSetCollate()`, because unstable ordering is what turns a one-row change into a whole-file diff.
◆ Prediction
The metadata system has absorbed digits, attributes and conversions in three consecutive releases, so the next likely addition is another storage decision moved into metadata rather than any change to the on-disk format.
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.
