Headlamp vs retroharmonize
A side-by-side editorial comparison of Headlamp and retroharmonize — release velocity, themes, recent moves, and the top alternatives to consider.
Headlamp vs retroharmonize: at a glance
What is Headlamp?
Headlamp's feed is mostly chart bumps; the plugin toolchain is where the actual work shows.
Most of what reaches this feed are Helm chart releases carrying a one-line project description and no changelog, roughly one every six weeks. The one entry with substance is headlamp-plugin 0.14.0, the tooling plugin authors use: a Windows shim fix, execSync replaced with execFileSync to remove a shell-injection path, missing type declarations added for theme customisation, and a long list of dependency security fixes.
What is retroharmonize?
Survey harmonization tooling that spent its last release earning its way back onto CRAN.
retroharmonize handles retrospective harmonization of survey microdata — reconciling value codes, value labels, variable names, and missing-value ranges across waves so separate surveys can be joined or panelled reproducibly. The most recent release was not about any of that: the package had been archived from CRAN when a dependency was archived, and the work went into refactoring the labelled_spss_survey vctrs integration, separating core, print, arithmetic, and vctrs methods, and passing checks across five platforms plus R-devel.

Headlamp's feed is mostly chart bumps; the plugin toolchain is where the actual work shows.
◆ Current state
Most of what reaches this feed are Helm chart releases carrying a one-line project description and no changelog, roughly one every six weeks. The one entry with substance is headlamp-plugin 0.14.0, the tooling plugin authors use: a Windows shim fix, execSync replaced with execFileSync to remove a shell-injection path, missing type declarations added for theme customisation, and a long list of dependency security fixes.
◆ Where it's heading
Headlamp's investment is visibly in the extension surface rather than the core UI — the plugin tool is where typing, linting and security posture are being tightened. The 0.14.0 scaffolding change is the notable signal: new plugins now generate an AGENTS.md and bundle example plugins so coding agents have context when working in a plugin repository. Chart releases will keep dominating the feed and telling you nothing.
◆ Prediction
Further plugin-tool releases focused on type coverage and authoring ergonomics are the likely next visible work; the chart cadence should continue unchanged.
retroharmonize
0.0INFRA · APIS
Survey harmonization tooling that spent its last release earning its way back onto CRAN.
◆ Current state
retroharmonize handles retrospective harmonization of survey microdata — reconciling value codes, value labels, variable names, and missing-value ranges across waves so separate surveys can be joined or panelled reproducibly. The most recent release was not about any of that: the package had been archived from CRAN when a dependency was archived, and the work went into refactoring the labelled_spss_survey vctrs integration, separating core, print, arithmetic, and vctrs methods, and passing checks across five platforms plus R-devel.
◆ Where it's heading
The design bet has been constant since the first release — comprehensive S3 classes that carry labels and missing-value semantics through every transformation, so the harmonization is documented rather than reconstructed. What has changed is where effort goes. Early releases added harmonization functions and a worked Arab Barometer case study; recent ones are code quality and CRAN survival. Note that the version numbering in this feed is not monotonic: 0.1.13 was released roughly nine months before 0.1.7, so version order here does not indicate release order.
◆ Prediction
Having just restored CRAN availability through a refactor rather than a feature, the near-term work is most likely consolidation of the vctrs integration the notes describe rather than new harmonization functions.
