frictionless-r vs Prometheus
A side-by-side editorial comparison of frictionless-r and Prometheus — release velocity, themes, recent moves, and the top alternatives to consider.
frictionless-r vs Prometheus: at a glance
What is frictionless-r?
frictionless turns its internals into a public extension surface for Data Package readers
frictionless is the R reference implementation of the Frictionless Data Package standard: read, edit and write datapackage.json plus its CSV resources. The 1.3.0 release is the first to make the package aware of which standard version a file targets, and the first to expose resource objects as a documented public API rather than an internal detail. Its release history arrives in irregular archive bursts rather than a steady cadence, and version numbers in the feed are not monotonic.
What is Prometheus?
Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default
3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.

frictionless turns its internals into a public extension surface for Data Package readers
◆ Current state
frictionless is the R reference implementation of the Frictionless Data Package standard: read, edit and write datapackage.json plus its CSV resources. The 1.3.0 release is the first to make the package aware of which standard version a file targets, and the first to expose resource objects as a documented public API rather than an internal detail. Its release history arrives in irregular archive bursts rather than a steady cadence, and version numbers in the feed are not monotonic.
◆ Where it's heading
The work has shifted from covering the standard to letting other packages build on top of it. Making resource() public, adding resource()<- for in-place overwrites, and moving package$directory and resource$read_from to attributes all separate the package's own state from the standard's properties, which is what downstream implementers need to add readers frictionless does not ship. The soft-deprecations of resources() and get_schema() point the same direction: a smaller, more deliberate public vocabulary.
◆ Prediction
The version() plumbing and the explicit warning on non-1.0 datapackage.json files read as groundwork for Data Package v2 support; expect the next substantive release to start reading v2 files rather than only detecting them.
Prometheus

Prometheus 3.14 ships the release candidate unchanged, duration expressions now on by default
◆ Current state
3.14.0 is byte-identical to the 3.14.0-rc.0 body published a week earlier, so the stable cut carries exactly what the candidate previewed: PromQL duration expressions enabled by default with the feature flag retired, first_over_time promoted to stable, Oracle Cloud service discovery added, and a set of start-timestamp experiments still behind flags. The performance work is the substantive half, with regex matchers on literal alternations, native histogram scrape parsing down roughly 49% in allocations, and a recursion-free text parser that closes a stack-overflow path on hostile exposition.
◆ Where it's heading
The project is spending its feature budget on start timestamps, appearing across PromQL, TSDB encoding, and remote write V2 in the same release but held behind use-start-timestamps and histograms-st-encoding. Everything else follows the established rhythm of promoting one experimental function per cycle and adding a cloud discovery source. The API deprecations are being staged carefully, warning now and rejecting at the next major.
◆ Prediction
Start timestamps are the obvious candidate to lose their feature flags once the encoding and remote-write halves have run together, and the stats parameter values now warned on will be rejected in the next major.
