Preview web apps live as your coding agent builds them with Amazon Bedrock AgentCore runtime

In short

The new capability relies on session endpoints that supply unique authenticated URLs to route HTTP and WebSocket traffic straight into the microVM. Developers can designate up to five allowed ports between 8000 and 12000, requiring target applications to bind to 0.0.0.0. Clients connect over port 443 and utilize host name prefixes to select the internal target port. To facilitate browser access without compromising authentication, a local SDK proxy signs and forwards requests automatically.

Preview web apps live as your coding agent builds them with Amazon Bedrock AgentCore runtime

Coding agents now build working web apps: a dashboard, a product page, a prototype that a product team wants to try. The fastest way to review that work is to open the app, use it, ask for a change, and check the result. That loop works well when the app keeps running where the agent edits it, so each change shows up in the browser within seconds. When the app must be copied out and deployed somewhere else first, every change waits for a deployment, and the review slows down to that pace.

Amazon Bedrock AgentCore is a platform to build, connect, and optimize agents at scale, with your choice of agent framework and foundation model (FM). AgentCore runtime, a capability of Amazon Bedrock AgentCore, runs each agent session in its own isolated microVM. With Session endpoints, you can open an app running in that session from your own browser. Session Endpoints give each session an authenticated URL that forwards each request’s HTTP…
