constants vs MotherDuck
A side-by-side editorial comparison of constants and MotherDuck — release velocity, themes, recent moves, and the top alternatives to consider.
constants vs MotherDuck: at a glance
What is constants?
The R package for CODATA constants rebuilt its symbol table on NIST's naming so future updates stop being hand work.
constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.
What is MotherDuck?
MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.
The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.

◆ Current state
constants exposes the CODATA recommended values of the physical constants to R, as a data frame plus symbol lists that carry units, uncertainties, or both. The package reached 1.0.0 on the 2018 CODATA release and has shipped once since, purely to track a units package update. Its surface is small and its release cadence is bound to CODATA, which revises every few years.
◆ Where it's heading
The direction set at 1.0.0 was to stop being a curated convenience wrapper and become a mechanical mirror of NIST. Hand-crafted symbol names were replaced with NIST's own ASCII symbols, categories adopted NIST's, and uncertainty switched from relative to absolute — all framed by the maintainer as necessary to make future CODATA updates routine. On top of that the package gained a correlation matrix and optional integration with the quantities package, moving it from a lookup table toward something that can propagate uncertainty.
◆ Prediction
Having rebuilt the symbol table specifically so CODATA revisions become mechanical, the next substantive release most likely tracks a new CODATA dataset rather than adding API. The experimental correlated-value support, disabled by default at 1.0.0, is the one part these entries flag as unfinished.

MotherDuck keeps wrapping its agent-native stack in the plumbing enterprises need to adopt it.
◆ Current state
The two capabilities MotherDuck has bet on — Flights for Python pipelines that MCP agents can drive, and Guides for the organizational context those agents read automatically — are now surrounded by the operational layer that makes them usable at scale: RBAC, org-wide admin visibility, regional availability in Sydney and Tokyo, runtime limits. The August 14 release adds the client surface that was still missing, a CLI covering auth, queries, Dives and Flights with scriptable output.
◆ Where it's heading
The pattern is consistent: ship an agent-facing capability, then spend the following weeks making it governable and reachable. Iceberg interoperability keeps widening — Databricks-managed tables, Cloudflare R2 as a persisted catalog, server-side attach — which positions MotherDuck as a compute engine over catalogs it does not own. The CLI extends the same logic to automation: anything the UI can do should be drivable from a script or a CI job.
◆ Prediction
Expect the CLI to leave preview with Flights and Dives management as its centre of gravity, and Guides to follow the same governance path Flights took — org-level controls, roles, and visibility rules layered on after the capability lands.
