Windmill
Windmill is dismantling the paywall between itself and the data stack
A side-by-side editorial comparison of ToolJet and vdiffr — release velocity, themes, recent moves, and the top alternatives to consider.
Two trains, one pattern: the LTS line gets hardening, the beta line gets the AI connectors.
ToolJet runs two parallel release lines and the split is stark. The 3.20 LTS train has spent the last week on security and stability — a full critical/high CVE sweep from container scanning, LDAP fixes, module repairs — with its one feature being global certificate support across data source connections plus automated RDS SSL setup. The 3.21 beta train carries the actual product work: datasource tagging and mentions, HubSpot, ServiceNow and QuickBooks AI integrations, link and password expiry controls, and group-based user filtering endpoints.
vdiffr finished its job in 2021 and has been tracking compilers ever since.
vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.

Enterprise deployment concerns are driving the LTS line — certificates, SSL automation, LDAP, CVE response and credential expiry are the recurring subjects, which is what a self-hosted internal-tools platform ships when it is selling into regulated estates. The beta line points at AI-assisted connectors to major SaaS systems, extending the AI features beyond app building into the data sources themselves. Expect the beta connector work to land in LTS once the 3.21 line stabilizes.
The AI integration list should keep growing along the same axis — CRM, ITSM, and finance systems — and the global certificate work suggests further connection-level security controls in the LTS train. A 3.21 LTS promotion is the next structural milestone.

The package reached its intended shape at 1.0.0, when snapshot management moved to testthat and vdiffr shed most of its own R and JavaScript code to become a reproducible SVG engine and nothing more. There is not much left to add to that, and the release stream since reads accordingly: it moves when a compiler, an R version, or testthat moves. For a testing dependency this is a healthy end state, though it does mean the package inherits whatever the graphics engine does to snapshot stability.
The entries do not support predicting a feature release. The likely next change is a compatibility fix prompted by a compiler or a testthat change, as every release since 1.0.2 has been.
