pedbuildr vs tibblify
A side-by-side editorial comparison of pedbuildr and tibblify — release velocity, themes, recent moves, and the top alternatives to consider.
pedbuildr vs tibblify: at a glance
What is pedbuildr?
pedbuildr reconstructs pedigrees from DNA, and it just got much faster at the search.
pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.
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.

◆ Current state
pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.
◆ Where it's heading
The package is bounded by two costs: how many candidate pedigrees it enumerates and how expensive each likelihood is. The recent release attacks both, parallelizing the likelihoods and speeding up enumeration in the common case. The earlier 0.3.0 release worked on the other end, adding inbreeding limits and a proper result class so the output of a large search is manageable. Releases are infrequent, roughly three years apart in this window.
◆ Prediction
Expect the candidate generation side to receive the same attention the likelihood side just did, since search space size is the remaining bound on what pedbuildr can reconstruct.

◆ 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.
