GravityKit vs saperlipopette: at a glance
What is GravityKit?
GravityKit ships a weekly Launch Log, and the interesting work is buried inside it
GravityKit publishes a consolidated weekly Launch Log across its whole add-on suite rather than per-product release notes, so a single entry can carry a genuine new capability and a batch of compatibility fixes side by side. The recent run covers Google Sheets export in GravityExport, adaptive DataTables columns, calendar sync fixes, unions in Multiple Forms 0.7.0, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility work. GravityView 3.0 in June, with the Vantage theme and AI-assisted View creation, remains the anchor release the suite is building on.
What is saperlipopette?
saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.

GravityKit ships a weekly Launch Log, and the interesting work is buried inside it
◆ Current state
GravityKit publishes a consolidated weekly Launch Log across its whole add-on suite rather than per-product release notes, so a single entry can carry a genuine new capability and a batch of compatibility fixes side by side. The recent run covers Google Sheets export in GravityExport, adaptive DataTables columns, calendar sync fixes, unions in Multiple Forms 0.7.0, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility work. GravityView 3.0 in June, with the Vantage theme and AI-assisted View creation, remains the anchor release the suite is building on.
◆ Where it's heading
Two threads persist. One is making Views handle data they previously could not — unions stacking entries from many forms without a shared field or custom code, field-to-field filtering, distance sorting, 3D map viewport loading. The other is compatibility maintenance against a moving platform, with Gravity Forms 3.0 fixes appearing in four consecutive Launch Logs. The MCP work on Block MCP and GravityKit MCP has gone quiet since June, which makes the AI thread the least predictable part of the suite.
◆ Prediction
Expect the export and data-source work to keep widening now that Google Sheets is wired in, and the Gravity Forms 3.0 fix stream to taper as the compatibility surface is worked through. Whether the MCP add-ons get further investment is not readable from these entries.

saperlipopette turned Git disasters into practice exercises, then passed peer review
◆ Current state
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
◆ Where it's heading
The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
◆ Prediction
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.
