ellipsis vs FusionAuth
A side-by-side editorial comparison of ellipsis and FusionAuth — release velocity, themes, recent moves, and the top alternatives to consider.
ellipsis vs FusionAuth: 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 FusionAuth?
FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.
FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

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.
FusionAuth
2.5DEVOPS
FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.
◆ Current state
FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.
◆ Where it's heading
Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.
◆ Prediction
The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.
