Authelia vs q2
A side-by-side editorial comparison of Authelia and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
Authelia vs q2: at a glance
What is Authelia?
Authelia's 4.39 line is a long hardening run, not a feature line
Authelia is an open-source authentication and authorization gateway, and the entire recent window is 4.39 point releases. The content is almost exclusively LDAP behaviour, OIDC/OAuth2 error semantics, and access-control evaluation, punctuated by two releases carrying security advisories — one for access-control rules missing a domain match without canonicalization, one for username canonicalization in Basic Auth against LDAP.
What is q2?
After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.
q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

Authelia's 4.39 line is a long hardening run, not a feature line
◆ Current state
Authelia is an open-source authentication and authorization gateway, and the entire recent window is 4.39 point releases. The content is almost exclusively LDAP behaviour, OIDC/OAuth2 error semantics, and access-control evaluation, punctuated by two releases carrying security advisories — one for access-control rules missing a domain match without canonicalization, one for username canonicalization in Basic Auth against LDAP.
◆ Where it's heading
The recurring theme is normalization: several fixes come down to Authelia comparing two strings that mean the same thing and getting a different answer. Domain matching, username canonicalization, issuer suffix checks and AMR consistency are all the same class of bug in different code paths, and they are being closed one at a time rather than by a single refactor. Alongside that, the LDAP client keeps yielding pool deadlocks, referral chasing, and health-check errors under load.
◆ Prediction
Given how many of these fixes cluster on the same identifier-comparison problem, the likely next step is more 4.39 patches in the same two areas — LDAP connection handling and access-control matching — before any 4.40 feature work becomes visible.
q2
6.3INFRA · APIS
After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.
◆ Current state
q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.
◆ Where it's heading
The light-dark epic is the shape of how this team retires a Quarto 1 feature: a design doc, then ThemeConfig growing a parsed dark variant, dual theme compilation with color-scheme emission, attributed stylesheet links, a color-mode toggle runtime, an accessibility-aware highlight-style reader, a brand light/dark seam, and an end-to-end verification pass against quarto-web before the docs land. One phase (D) was deferred with its options recorded rather than dropped. Around it, panel-tabset support lands, format.html.css is finally copied and rebased per page, and the llms companion output gains a link-format attribute so authors control where companion links point — the one thread tying this release back to the v0.22.0 work.
◆ Prediction
Expect the remaining Q1 parity items to keep setting the release agenda, with the deferred light-dark phase D and the freshly opened panel-tabset plan the two named strands most likely to fill the next few tags. npx distribution for the standalone Quarto Hub MCP bundle is still the only distribution item the notes explicitly call planned.
