dqcheckr vs SuperTokens: at a glance
What is dqcheckr?
dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.
What is SuperTokens?
SuperTokens is hardening SAML and building a migration path off other auth providers.
SuperTokens is an open-source authentication service, and its core repo is running a 12.0 canary line alongside stable patches. The work in this window falls into two piles: SAML security — XML signature wrapping protection in 12.0.2-canary, further hardening in the 12.0.10 release — and migration mode, where new core-user-data records can be created as MIGRATED and the transition is now blocked while inconsistent users exist. Release notes are thin, usually a PR title or two per tag.

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
◆ Current state
dqcheckr runs configurable data-quality checks over files and DuckDB tables, driven by YAML dataset configs and recording results as snapshots. The 0.2.0 release added the ability to compare two historical snapshots and report per-column statistical drift, schema changes and trend charts, extending the tool from point-in-time checking into change over time. The most recent tag, 0.3.0, attacks the other friction point by generating the config itself from a sniff pass over the data.
◆ Where it's heading
Both moves point the same way: reduce what the operator has to write and know. Config generation removes the hand-authored YAML that gated first use, list_runs() and validate_config() make an existing setup inspectable, and the snapshot comparison turns accumulated run history into a second product surface. Check coverage keeps widening underneath — outlier detection, composite keys, row-count and file-size ceilings — and the reporting layer moved from rmarkdown to Quarto, with existing 0.1.x databases auto-migrated on first run.
◆ Prediction
Expect the generated configs and the drift reports to converge, so a sniffed config can seed thresholds from the snapshot history rather than from defaults, plus continued growth in the numbered QC check catalogue.
SuperTokens
2.5INFRA · APIS
SuperTokens is hardening SAML and building a migration path off other auth providers.
◆ Current state
SuperTokens is an open-source authentication service, and its core repo is running a 12.0 canary line alongside stable patches. The work in this window falls into two piles: SAML security — XML signature wrapping protection in 12.0.2-canary, further hardening in the 12.0.10 release — and migration mode, where new core-user-data records can be created as MIGRATED and the transition is now blocked while inconsistent users exist. Release notes are thin, usually a PR title or two per tag.
◆ Where it's heading
Migration mode plus account-linking exploration is the tell: this is infrastructure for importing an existing user base from another provider without breaking identity linkage mid-flight, and the guard added in 12.0.5-canary shows they hit the inconsistent-state case in practice. The SAML work runs in parallel because enterprise SAML is what a team is usually migrating toward. Also worth noting: an automated contributor, supertokens-agent-runner, opened its first PRs in this window, so part of the fix and test volume is now agent-authored.
◆ Prediction
A stable 12.x release consolidating the canary migration-mode work is the readable next step, likely once the MIGRATED transition guards have run without incident. More SAML hardening should be expected given two separate fixes landed in this window alone.
