rerddap vs secretbase
A side-by-side editorial comparison of rerddap and secretbase — release velocity, themes, recent moves, and the top alternatives to consider.
rerddap vs secretbase: at a glance
What is rerddap?
An ERDDAP client steadily lowering the cost of pulling large oceanographic extracts
rerddap fetches gridded and tabular data from ERDDAP servers into R. The recent releases follow one practical thread — making large extracts cheaper to move — alongside routine robustness work on error messages and failure modes. 1.3.0 brings parquet output to `griddap()` and adds a function that estimates a download's size before the request is made.
What is secretbase?
secretbase quietly grew from a hashing package into a serialization toolkit
secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.

An ERDDAP client steadily lowering the cost of pulling large oceanographic extracts
◆ Current state
rerddap fetches gridded and tabular data from ERDDAP servers into R. The recent releases follow one practical thread — making large extracts cheaper to move — alongside routine robustness work on error messages and failure modes. 1.3.0 brings parquet output to `griddap()` and adds a function that estimates a download's size before the request is made.
◆ Where it's heading
Parquet support has propagated across the package one function at a time: introduced for `tabledap()` in 1.2.0 where the maintainer reports up to 90% smaller files for large extracts, patched in 1.2.3, and extended to `griddap()` in 1.3.0. The size-estimation function added alongside it addresses the same problem from the other end, letting a user find out what a request will cost before committing to it. Around this, the package has absorbed the usual CRAN-driven hardening, notably making all external resource requests fail gracefully.
◆ Prediction
Expect the remaining data-access paths to converge on the same parquet-plus-pre-flight-estimate pattern, since that is how the last three feature releases have each extended it. The entries do not indicate work beyond data retrieval.

◆ Current state
secretbase provides SHA-3, SHAKE, BLAKE3 and related hashing in R with a small C footprint and no dependencies. Over 2026 it has accumulated a second identity: CBOR, base58, JSON and URL-safe base64 encoders and decoders now sit alongside the hash functions. Releases are frequent, short and each does one thing — a format added, a conversion sped up, an undefined-behaviour warning cleared.
◆ Where it's heading
The additions are not arbitrary. CBOR is a binary format for structured data, JSON its text counterpart, base58 the checksummed encoding used for identifiers — together they cover what a process needs to put an R object on a wire and get it back, which is a different job from digesting bytes. The maintainer also maintains R's high-performance messaging stack, and a dependency-free codec that handles integers, floats, strings, raw vectors and lists is exactly what that stack would consume.
◆ Prediction
Every format added so far has come with an RFC number and a minimal implementation rather than a wrapped library, so further additions are likely to follow the same pattern; the encoders are also being optimized after they land, suggesting performance passes on CBOR and JSON before anything new.
