Infisical vs Windmill: at a glance
What is Infisical?
Folder-level RBAC lands, and approvals finally get a webhook to talk to.
Infisical ships near-daily across four surfaces — secrets management, PKI and certificate manager, PAM, and KMS. This release adds folder-level RBAC, so permissions can be scoped inside a project rather than only at project and environment level, and gives approvals and change requests their own webhook events. PKI keeps widening: a GCP Certificate Manager sync, Windows and Linux pre-fetch commands for PKI syncs, and certificate renewals exposed so agents can follow them. Project retention limits and Kubernetes managed-identity auth templates round it out, alongside a long run of v3 UI migration work.
What is Windmill?
Windmill gives its AI agents a test harness, the piece that lets them into production flows
Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.

Folder-level RBAC lands, and approvals finally get a webhook to talk to.
◆ Current state
Infisical ships near-daily across four surfaces — secrets management, PKI and certificate manager, PAM, and KMS. This release adds folder-level RBAC, so permissions can be scoped inside a project rather than only at project and environment level, and gives approvals and change requests their own webhook events. PKI keeps widening: a GCP Certificate Manager sync, Windows and Linux pre-fetch commands for PKI syncs, and certificate renewals exposed so agents can follow them. Project retention limits and Kubernetes managed-identity auth templates round it out, alongside a long run of v3 UI migration work.
◆ Where it's heading
Two threads run underneath the release stream. Consolidation continues — dynamic secrets moved onto a shared provider registry this release, the same pattern that let native integrations enter deprecation in v0.162.22. The second is authorization getting finer rather than broader: folder RBAC, certificate private-key reads scoped to the certificate subject, LDAP bind passwords no longer returned on GET, and approval checks that respect validation rules. The product is being made safe to hand to more people inside one organisation, not just to more organisations.
◆ Prediction
Approval and change-request webhooks are the eventing half of a workflow whose UI shell just moved to v3, so external approval routing — the events feeding a reviewer outside Infisical — is the natural next step. The changelog is a PR list and states no plan.

Windmill gives its AI agents a test harness, the piece that lets them into production flows
◆ Current state
Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.
◆ Where it's heading
The AI work has moved through a recognisable sequence: first let the assistant build things, then constrain what it may do without approval, then make its output reviewable and revertible, and now make agents measurable against a fixed set of cases. That is the arc of taking AI from a demo surface to something you are willing to put in a scheduled flow. In parallel, Windmill keeps pulling data-stack runtimes inside its own execution model rather than integrating with them, and keeps giving away runtimes that were previously licensed.
◆ Prediction
Evals are the obvious hook for regression gating, so expect them to be callable from a flow or CI rather than only from the agent card, and expect the eval run history to feed the same version-comparison surface the session artifacts already use.
