Auth0 joins the Vercel Marketplace

Vercel added Auth0 to the Vercel Marketplace on 2026-06-15, allowing teams to attach Auth0 authentication to a Vercel app in a few clicks.
The integration automatically provisions an Auth0 application connected to the selected Vercel project.
It includes out-of-the-box support for Next.js applications through the Auth0 Next.js SDK.
Auth0 provides hosted user management features including dashboards, sessions, and roles for application access control.
Authentication configuration can be synced across Development, Preview, and Production environments.
Vercel positions the integration for securing both standard web applications and agentic workflows built on modern frameworks.

AWS, Deep Agents and Bedrock AgentCore workflow outlined

AWS published a technical walkthrough for building context-rich research agents with LangChain Deep Agents and Amazon Bedrock AgentCore
The pattern uses a coordinator agent that checks AgentCore Memory, launches three browser subagents in parallel, and sends the combined results to an analyst subagent
Each research subagent runs in its own AgentCore Browser MicroVM with a real Chromium browser, while the analyst runs in an isolated Code Interpreter environment
The example model configuration uses Claude Sonnet via Amazon Bedrock with the model ID `us.anthropic.claude-sonnet-4-6` and a `read_timeout=300` setting
AWS said the Browser toolkit exposes actions such as navigation, text extraction, clicking, typing, scrolling, hyperlink extraction, and element waiting, with `session_wait_timeout` raised from 10 to 60 seconds in the sample
The Code Interpreter environment is described as a full Python runtime with pandas, matplotlib, and numpy preinstalled for chart generation and markdown report output
AWS also positioned AgentCore as a native sandbox provider in the Deep Agents CLI and said the same agent can later be deployed to Bedrock AgentCore Runtime as a managed session-isolated service
Observability is handled through Amazon CloudWatch via Bedrock AgentCore Observability or through LangSmith traces, according to the post
