tf vs ToolJet
A side-by-side editorial comparison of tf and ToolJet — release velocity, themes, recent moves, and the top alternatives to consider.
tf vs ToolJet: at a glance
What is tf?
tf gave functional data a second dimension: curves whose values are vectors.
tf supplies the vector classes underneath the tidyfun stack — tfd for raw functional observations, tfb for basis-represented ones, both built on vctrs so curves sit in a data frame column and behave like any other vector. Until July that codomain was scalar. The 0.5.0 release adds tfd_mv and tfb_mv, classes for functions whose values are vectors in R^d, and rebuilds the analysis verbs to match.
What is ToolJet?
Observability lands on OpenTelemetry semconv in the LTS train
ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.

◆ Current state
tf supplies the vector classes underneath the tidyfun stack — tfd for raw functional observations, tfb for basis-represented ones, both built on vctrs so curves sit in a data frame column and behave like any other vector. Until July that codomain was scalar. The 0.5.0 release adds tfd_mv and tfb_mv, classes for functions whose values are vectors in R^d, and rebuilds the analysis verbs to match.
◆ Where it's heading
The package is widening what a functional observation can be, then porting the toolkit onto it. Registration arrived first in 0.4.0 for univariate curves and immediately gained an srvf_mv method for aligning components jointly, and tfb_mfpc() ports principal component analysis to the multivariate case with a single set of scores shared across components. Alongside that runs steady dependency shedding — mvtnorm and pracma both replaced by inlined samplers that reproduce prior draws bit-for-bit, glue dropped for cli in the previous release — and an unusually long tail of NA-handling and edge-case fixes, several caught in pre-release review of the new classes.
◆ Prediction
The new classes ship with FPCA, registration and shape alignment but the release notes describe tidyfun::tf_unnest() as the consumer of one new export, so the visible next step is the rest of the tidyfun stack catching up to vector-valued columns. Expect follow-up patches on the vctrs casting paths, which is where most of this release's late fixes clustered.

Observability lands on OpenTelemetry semconv in the LTS train
◆ Current state
ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.
◆ Where it's heading
Most releases are small and corrective, with feature work collecting into occasional larger LTS drops. The recurring themes are component sizing, which appears in nearly every release, and enterprise-operations work — global data source certificates, automated RDS SSL setup, CVE patching, and now standards-based observability. It reads as a platform hardening for self-hosted enterprise deployments.
◆ Prediction
Expect the dynamic-height and sizing pass to continue across the remaining widgets, and the beta line's AI datasource integrations to graduate into the LTS train. Standardizing on OTel semconv suggests exported traces and metrics for customer-run dashboards next.
