Dendrite Vault is a Chrome extension categorized under Developer Tools that describes itself simply as an "authentication session handler for AI Agents." Its job is to bridge the gap between AI agents that need to act on the web and the many web applications that only work behind a login. Rather than having an agent store and replay raw credentials, the extension manages authenticated sessions inside the browser so an agent can reach the resources it was authorized to use.
It is published by Dendrite, a Swedish software consultancy that builds systems and automates data flows for clients, with the extension itself attributed to developer Sebastian Thunman in Stockholm. The extension is early-stage — version 0.0.2, updated in September 2024 — and it declares that the personally identifiable and authentication information it handles is not sold to third parties and is not used for creditworthiness or lending purposes.
Because it is such a focused developer utility with a small install base and no user ratings yet, Dendrite Vault is best understood as early tooling for teams building or piloting AI agent workflows that must touch authenticated web apps. It sits in the fast-moving category of "agent session" extensions, alongside credential-autofill tools for owner-authorized agents.
