Agent! is an open-source, native macOS application that aims to replace subscriptions to Claude Code, Cursor, and Cline — all in one local app. Built with SwiftUI, it connects to 17 LLM providers including Claude, GPT-4o, Gemini, Grok, and Ollama for fully local runs, and taps Apple Intelligence for on-device token compression when context windows overflow. The standout feature is Time Machine-style file backup with one-click undo on any edit — a safety net conspicuously missing from most AI coding tools today. It also controls macOS via the Accessibility API, automates Safari and Playwright for web tasks, executes shell commands, and handles iMessage-triggered commands. Multi-tab support lets you run parallel agent sessions without context bleed. Zero telemetry, bring-your-own-API-keys, MIT licensed. For developers tired of juggling multiple AI coding subscriptions or uncomfortable with code leaving their machine, this is a compelling local-first alternative that's appeared on Hacker News today.

Azure Foundry Hosted Agents
Per-session isolated agent sandboxes on Azure — scale to zero, any framework

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.
Reviewer scorecard
“The Time Machine undo alone makes this worth trying — every AI coding tool should have this and almost none do. Bring-your-own-keys with 17 providers means you're not locked in. The Accessibility API integration is powerful for automating macOS tasks beyond just code.”
“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.”
“macOS-only by definition, and native apps require significant maintenance across OS updates. The GitHub repo is brand new — no track record, unknown reliability in production codebases. Apple Intelligence compression sounds clever until you realize it adds another dependency and single point of failure.”
“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.”
“Local-first AI coding is the natural endgame for privacy-conscious developers and regulated industries. The Time Machine approach hints at a future where AI edits are fully auditable and reversible — a property that will become legally required in some domains.”
“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.”
“The multi-tab parallel agent feature is genuinely exciting for creative workflows — run one agent exploring a design system while another drafts the implementation. Zero subscriptions means a solo creator can access frontier models without a $200/month tab.”
“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.”
