pedmut vs tibblify
A side-by-side editorial comparison of pedmut and tibblify — release velocity, themes, recent moves, and the top alternatives to consider.
pedmut vs tibblify: at a glance
What is pedmut?
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().
What is tibblify?
tibblify learned to derive its own specs from OpenAPI, removing the step users disliked most
tibblify converts nested lists and JSON into rectangular tibbles using an explicit specification of the expected structure. Its 0.2.0 rewrite moved the engine to C and reset the API; 0.3.1 then added a path to generate specifications from an OpenAPI document rather than hand-writing them. 0.4.0 in May 2026 is the first release in over two years, and it is a breaking cleanup.

pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
◆ Current state
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().
◆ Where it's heading
The consistent goal is making models satisfy the mathematical properties downstream algorithms require. Reversibility, stationarity, and lumpability each unlock something in pedprobr, and the package keeps adding ways to coerce an arbitrary model into having them. lumpMutSpecial() is explicitly incomplete, described as covering only some cases with more possibly to follow, which sets up the main open thread.
◆ Prediction
Expect additional special lumping cases to be implemented, since the package documents the current coverage as partial and pedprobr's likelihood performance depends directly on it.

◆ Current state
tibblify converts nested lists and JSON into rectangular tibbles using an explicit specification of the expected structure. Its 0.2.0 rewrite moved the engine to C and reset the API; 0.3.1 then added a path to generate specifications from an OpenAPI document rather than hand-writing them. 0.4.0 in May 2026 is the first release in over two years, and it is a breaking cleanup.
◆ Where it's heading
The arc runs from 'write a spec by hand' toward 'the spec comes from somewhere else'. Alongside the OpenAPI importer, guess_tspec() gained exported variants so users can override its dispatch, and untibblify() now picks up the tib_spec attribute automatically. 0.4.0's breaking change prefixes all arguments of dot-accepting functions with a period to avoid collisions with column names, softened by a once-per-session deprecation warning, and refactors the entire codebase.
◆ Prediction
The un-dotted argument forms are explicitly slated for removal, so the next release most likely completes that deprecation. Whether the 0.4.0 refactor introduced corner-case regressions is the open question the release notes themselves raise.
