Microsoft Azure's Foundry Agent Service now offers Hosted Agents in public preview — per-session isolated compute sandboxes purpose-built for running AI agents at scale. Each session gets its own container with a persistent filesystem, internet access (optional), and a Python environment pre-loaded with common agent dependencies. Sessions spin up in seconds and terminate — and stop billing — the moment the agent task completes. The design is framework-agnostic: it officially supports LangGraph, OpenAI Agents SDK, Claude Agent SDK, and Microsoft's own Agent Framework, with others planned. This removes one of the most awkward parts of deploying agents in production: figuring out where they actually run. The persistent filesystem per session means agents can read and write files across their task without external storage configuration. Pricing is $0.0994/vCPU-hour and $0.0118/GiB-hour — competitive with Lambda/Cloud Run for bursty workloads. The service is available in six Azure regions at launch. For enterprises already invested in Azure, this is a compelling "we just figured out the infra" moment. Independent developers can also use it without an enterprise agreement.

Craft Agents OSS is an open-source desktop application built on Anthropic's Claude Agent SDK, offering a polished GUI for managing multiple AI agent sessions simultaneously. Built by Luki Labs and released under Apache 2.0, it fills the gap between raw API access and the full Claude.ai web interface — giving developers and power users a native desktop experience with serious capability depth. The app supports three permission modes that make it genuinely useful for real work: Explore (read-only, safe for exploring codebases), Ask to Edit (approval-based, for supervised automation), and Auto (unrestricted, for trusted workflows). It connects to MCP servers, REST APIs from Google, Slack, and Microsoft, and local filesystems, with real-time streaming responses and full tool call visualization. A multi-session workflow with Todo → In Progress → Needs Review → Done status tracking makes it feel more like a project management system than a chat interface. Built on Electron + React with encrypted credential storage and a headless server mode, Craft Agents is architecturally serious. It's available as a one-line installer for macOS, Linux, and Windows. With the Claude Agent SDK gaining traction, this is the first polished desktop client that treats agents as long-running workflows rather than single-turn conversations.
Reviewer scorecard
“Framework-agnostic hosted sandboxes with scale-to-zero is exactly what I need for deploying agents without maintaining my own Kubernetes cluster. The per-session isolation eliminates a whole class of security concerns I was handling manually. The Claude Agent SDK support means I don't have to choose between Azure and my preferred model.”
“The three permission modes — Explore, Ask to Edit, Auto — is the right model for how I actually use agents. I want read-only exploration when I'm learning a codebase and auto mode when I'm in flow. That plus MCP server support makes this my new default agent UI.”
“Public preview means production instability risk and pricing could change significantly at GA. The cold start time for agent sessions needs to be benchmarked against real workloads before committing. And six regions is thin coverage for global deployments — wait for broader availability.”
“Electron desktop apps for AI agents have a graveyard of predecessors — most people end up in the terminal or the browser anyway. The Claude-only model dependency is also a real limitation; when Anthropic changes their SDK or pricing, the whole platform needs to adapt.”
“The battle for agent infrastructure is the next cloud wars — and Microsoft just answered Google Cloud's agent platform launch with their own. Framework-agnostic compute that works with any model provider is a smart commoditization play: own the infrastructure layer, let the model battle play out above it.”
“Agent session management as a first-class concept is where the whole category is heading. Craft Agents is early proof that the IDE model — multi-session, persistent, project-aware — is the right UX paradigm for AI agents, not the chat-box model we inherited from GPT-3 days.”
“This is squarely developer infrastructure — not directly relevant to creative workflows unless your studio runs its own agents. Worth watching for the ecosystem tools that get built on top of it.”
“File attachments with automatic format conversion plus the Slack/Google API integrations mean I can finally have agents that work across my whole toolkit, not just the terminal. The one-line installer is the detail that will make this actually get adopted.”
