Infisical vs RSA: at a glance
What is Infisical?
A credential platform assembled two or three pull requests at a time, never a headline
Infisical is assembling a credential platform rather than a secrets store, with PKI, PAM, KMIP and secret rotation advancing in parallel. No release carries a headline; each version lands two or three pull requests per pillar. The newest, v0.162.21, brings PAM access control improvements, expanded certificate-manager telemetry and a migration of project service tokens onto the v3 UI — the same pattern as the release before it, which added KMIP auto-renewal and removed the legacy environment dashboard.
What is RSA?
Four years quiet, then two releases ninety seconds apart, both about drawing better plots
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.

◆ Current state
Infisical is assembling a credential platform rather than a secrets store, with PKI, PAM, KMIP and secret rotation advancing in parallel. No release carries a headline; each version lands two or three pull requests per pillar. The newest, v0.162.21, brings PAM access control improvements, expanded certificate-manager telemetry and a migration of project service tokens onto the v3 UI — the same pattern as the release before it, which added KMIP auto-renewal and removed the legacy environment dashboard.
◆ Where it's heading
PKI is furthest along and PAM is the fastest-moving: it has picked up machine identities, Redis as an account type, and now finer access control, following the same absorb-the-identity-model path secrets took. Running underneath everything is the v3 UI migration, which has been consuming one settings surface per release — the environment dashboard, then service tokens. Read as a whole, the changelog describes a product deliberately refusing to announce itself.
◆ Prediction
Expect the v3 migration to finish sweeping the remaining project settings surfaces and PAM to keep collecting account types the way PKI collected sync destinations; the expanding certificate-manager telemetry suggests that pillar is being measured before it is expanded.

Four years quiet, then two releases ninety seconds apart, both about drawing better plots
◆ Current state
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.
◆ Where it's heading
The statistical core has been stable since 0.10.0 in 2020, which added control variables, pooled centering and a corrected AICc. Everything since is either plot customisation or a reaction to a dependency — lavaan model comparison, rgl deprecations, tkrplot on Apple Silicon, the ggplot2 fill aesthetic. This is a mature method implementation in maintenance, where the visible work is making its surface plots publishable.
◆ Prediction
Further releases are most likely dependency reactions, with rgl and ggplot2 the two that have repeatedly forced changes, and plot customisation arriving in batches whenever the maintainer returns to the package.
