b3doc vs Dragonfly
A side-by-side editorial comparison of b3doc and Dragonfly — release velocity, themes, recent moves, and the top alternatives to consider.
b3doc vs Dragonfly: at a glance
What is b3doc?
A small B-Cubed utility for turning R Markdown into publishable docs
b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.
What is Dragonfly?
Dragonfly spends its releases on correctness in the parts of Redis compatibility nobody tests.
The visible window is almost entirely correctness and internals work on the 1.39/1.40 lines. The newest release consolidates two tiering knobs into a single tiered_max_pending_bytes and exports it to metrics. Behind it sit a memory-accounting backport, a cluster fix that journals FLUSHSLOTS from inside the flush transaction, and a HyperLogLog resync with valkey upstream that pulled in a CVE fix and exposed three Dragonfly-local bugs.

A small B-Cubed utility for turning R Markdown into publishable docs
◆ Current state
b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.
◆ Where it's heading
The direction is toward predictability over flexibility. The replace argument arrived in 0.2.0 generalising the earlier logo-specific behaviour, then 0.3.0 pulled regex support back out of it because escape characters and over-broad matches caused unintended edits. That is a maintainer choosing a narrower tool that fails obviously over a general one that fails quietly — a reasonable trade for a package that rewrites files in place.
◆ Prediction
Expect continued small releases driven by the documentation pipeline's needs, with output-quality defaults and front-matter handling the likely subjects rather than new functions.
Dragonfly
5.0INFRA · APIS
Dragonfly spends its releases on correctness in the parts of Redis compatibility nobody tests.
◆ Current state
The visible window is almost entirely correctness and internals work on the 1.39/1.40 lines. The newest release consolidates two tiering knobs into a single tiered_max_pending_bytes and exports it to metrics. Behind it sit a memory-accounting backport, a cluster fix that journals FLUSHSLOTS from inside the flush transaction, and a HyperLogLog resync with valkey upstream that pulled in a CVE fix and exposed three Dragonfly-local bugs.
◆ Where it's heading
Two threads run through this window. One is upstream parity — the hyperloglog sync explicitly re-forks from valkey and keeps upstream formatting so future syncs stay cheap, which is a maintenance-cost decision as much as a correctness one. The other is the RESP IO loop v2 migration, visible in a pub/sub ordering fix gated on the v1 loop and in tests being skipped on the v1 leg of the regression matrix. Dragonfly is hardening a drop-in Redis replacement in the places where drop-in claims usually break: cluster operations, pub/sub ordering under pipelining, and memory accounting.
◆ Prediction
Expect continued RESP IO loop v2 work and more upstream syncs on forked Redis internals. The tiering flag consolidation plus its metrics export suggests tiered storage tuning is the next area to get operator-facing surface.
