Infisical vs Stacker: 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 Stacker?
Stacker's AI agent has absorbed every part of app building except the data itself.
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.

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.
Stacker
0.0INFRA · APIS
Stacker's AI agent has absorbed every part of app building except the data itself.
◆ Current state
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.
◆ Where it's heading
The sequencing is deliberate: each release hands the agent one more thing that previously required the no-code editor, while the company repeatedly reassures users that the full editor still works on AI-built apps. That dual framing — build by conversation, refine by hand — is the position Stacker is defending, and it is a reasonable answer to pure prompt-to-app tools that leave nothing to adjust afterwards. The portal release is the notable widening, since it points the agent at the external-user product rather than internal tools.
◆ Prediction
Every surface except data connection has now been handed to the agent; connecting and mapping an external source — the step still done manually before any of this works — is the remaining gap, and the spreadsheet uploader is the first move toward closing it.
