AWS adds AgentCore Session endpoints to preview coding agent web apps live in browser
AWS ML Blog · rss · 2026-10-31
AWS ML Blog walks through Session endpoints in Amazon Bedrock AgentCore runtime: each agent session gets an authenticated URL (SigV4 or JWT) forwarding HTTP and WebSocket traffic to ports you allow (8000–12000), so you can watch a coding agent's Vite site update in-browser without redeploys. A local proxy endpoint in the SDK adds credentials for browsers. Includes a full notebook with a Claude Haiku 5.5-powered agent running on port 8080 beside the dev server.
