profileCI vs Windmill
A side-by-side editorial comparison of profileCI and Windmill — release velocity, themes, recent moves, and the top alternatives to consider.
profileCI vs Windmill: at a glance
What is profileCI?
Profile-likelihood confidence intervals for any fitted model, in a feed that publishes out of order.
profileCI computes confidence intervals from the profile log-likelihood for user-supplied fitted models, generalising what confint.glm does for GLMs to any model object exposing a log-likelihood. The releases handle the awkward cases that make profiling fail in practice: infinite limits when the profile never drops below the interval threshold, bounded profiling ranges, and interpolation that breaks down near the limits. Only convex log-likelihoods are supported, so disjoint intervals are out of scope by design.
What is Windmill?
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.

profileCI

Profile-likelihood confidence intervals for any fitted model, in a feed that publishes out of order.
◆ Current state
profileCI computes confidence intervals from the profile log-likelihood for user-supplied fitted models, generalising what confint.glm does for GLMs to any model object exposing a log-likelihood. The releases handle the awkward cases that make profiling fail in practice: infinite limits when the profile never drops below the interval threshold, bounded profiling ranges, and interpolation that breaks down near the limits. Only convex log-likelihoods are supported, so disjoint intervals are out of scope by design.
◆ Where it's heading
Work is concentrated on numerical reliability rather than scope: 1.1.1 replaced quadratic with monotonic cubic spline interpolation because the quadratic form could fail, and corrected parameter values stored near the confidence limits. The feed publishes these out of order, with the v1.0.0 entry stamped six months after v1.1.0 and carrying the package's full description rather than a changelog, so release order should be read from the version numbers rather than the dates. The same maintainer's revdbayes has been in pure maintenance across this period, which places profileCI as the more active project.
◆ Prediction
Expect further robustness work at the profiling limits and more logLikFn methods for common model classes, following the nls method added in 1.1.0.
Windmill
8.8INFRA · APIS
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
◆ Current state
In a single fortnight Windmill moved BigQuery and Snowflake out of the Enterprise license and made dbt projects a first-class runtime executing on the customer's own workers. Around that, deployment got simpler — one target derived from workspace lineage, compare-and-deploy into any workspace — and the AI session surface keeps thickening: markdown artifacts, then version history over those artifacts with the assistant able to read past versions.
◆ Where it's heading
The community edition is being loaded up with exactly what a data team needs to run a real trial: warehouse connectors, an unmodified dbt project, storage quota instead of an upload cap. Enterprise is being repositioned around scale and governance rather than feature access. The AI sessions track is developing on its own clock, moving from chat toward durable, versioned work products that survive a session.
◆ Prediction
Expect AI session artifacts to gain server-side persistence and sharing, since they are still stored in the browser and tied to the session. On the data side, the dbt runtime is likely to grow scheduling and lineage integration with the pipelines alpha rather than staying a standalone script language.
