ellipsis vs Fiber
A side-by-side editorial comparison of ellipsis and Fiber — release velocity, themes, recent moves, and the top alternatives to consider.
ellipsis vs Fiber: at a glance
What is ellipsis?
ellipsis' checks live in rlang now; the package is a compatibility shim.
ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.
What is Fiber?
Fiber v3 has sat in release candidate for months while v2 gets one-line patches
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

ellipsis' checks live in rlang now; the package is a compatibility shim.
◆ Current state
ellipsis provides check_dots_used(), check_dots_unnamed() and check_dots_empty() for catching arguments silently swallowed by dots. Its functional development finished in 2019 across the 0.2.0 and 0.3.0 releases. The two releases since deal only with rlang and CRAN, and 0.3.3 makes the rlang dependency unconditional.
◆ Where it's heading
The package built its full surface quickly, hardened it once by switching the check functions from warnings to errors, then saw the ideas move upstream. These checks are part of rlang's own API now, which leaves ellipsis as a compatibility layer for packages still importing it directly. The 0.3.3 change to depend on rlang unconditionally states that relationship plainly.
◆ Prediction
With the functionality living in rlang, the next release is most likely another CRAN-driven fix; there is no sign of new checks being added here.

Fiber v3 has sat in release candidate for months while v2 gets one-line patches
◆ Current state
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.
◆ Where it's heading
v3 is the answer to Fiber's longest-standing objection, that building on fasthttp cuts a project off from the net/http middleware ecosystem. Making both handler styles native reframes Fiber as compatible rather than separate. But rc.3 dates to late 2025 and nothing newer has landed in this feed, while v2 patches keep arriving through August — a long release candidate stretch that leaves users choosing between a stable branch in pure maintenance and a v3 that has not been declared final.
◆ Prediction
The next meaningful entry is either a v3.0.0 final or a further RC; until one lands, expect the v2 line to continue receiving single-PR backports and security patches.
