SuperTokens vs Authelia
A side-by-side editorial comparison of SuperTokens and Authelia — release velocity, themes, recent moves, and the top alternatives to consider.

SuperTokens vs Authelia: at a glance
What is SuperTokens?
SuperTokens is building v12 in canary around one hard problem: migrating existing users
The visible releases are all v12.0.x canary builds — no stable v12 in the window. The work concentrates on account linking and a MIGRATED mode for core user directories, with supporting changes for SAML signature-wrapping protection, an activity_log table, and OpenTelemetry span annotations.
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.

SuperTokens is building v12 in canary around one hard problem: migrating existing users
◆ Current state
The visible releases are all v12.0.x canary builds — no stable v12 in the window. The work concentrates on account linking and a MIGRATED mode for core user directories, with supporting changes for SAML signature-wrapping protection, an activity_log table, and OpenTelemetry span annotations.
◆ Where it's heading
The migration-mode thread is the spine here. First new core user directories were allowed to be created as MIGRATED, then the transition into MIGRATED was blocked while inconsistent users exist, then account linking itself was reopened for exploration. That sequence reads as a team discovering that letting a running deployment switch identity models mid-flight is where the correctness risk lives, and adding guardrails before shipping it. Everything else in the window is scaffolding around that: audit-shaped activity logging, tracing annotations, and CI cleanup.
◆ Prediction
A stable v12 looks gated on the account-linking and migration-mode work settling; expect further canaries tightening the conditions under which a deployment is allowed to change modes before any general release.

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.
