Infisical vs Stacker: at a glance
What is Infisical?
Infisical's alert channels gain webhook auth as audit-log streams learn to warn when they drop.
Infisical releases several times a week, pairing feature work with a v3 UI migration that now reaches native integration creation pages and Certificate Manager. v0.166.8 adds authentication and custom headers to webhook alert channels, an alert when an audit-log stream starts dropping logs, and Secrets Overview telemetry. The prior release added Kafka dynamic secrets and moved PAM onto the shared alerting module.
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.

Infisical

Infisical's alert channels gain webhook auth as audit-log streams learn to warn when they drop.
◆ Current state
Infisical releases several times a week, pairing feature work with a v3 UI migration that now reaches native integration creation pages and Certificate Manager. v0.166.8 adds authentication and custom headers to webhook alert channels, an alert when an audit-log stream starts dropping logs, and Secrets Overview telemetry. The prior release added Kafka dynamic secrets and moved PAM onto the shared alerting module.
◆ Where it's heading
Two tracks keep advancing together: shared platform services, with alerting now the busiest, and a lineup split into separately packaged products with per-product billing. Alerting has gone from reminders to PAM to audit-log health in a week, which makes it a cross-product backbone. The v3 UI migration is in its final stretches across integrations.
◆ Prediction
Expect more products and events wired into the shared alerting module and the v3 UI migration to finish across the remaining screens. Whether Agent Vault reaches a GA announcement is not visible in the entries.
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.
