Background Agent
Also known as: Background Agent / バックグラウンドエージェント / 非同期エージェント
Agent mode where tasks run server-side without the user terminal — Claude Code agents keep working after you close and notify on completion.
Overview
Background agents decouple long-running tasks (refactors, test suites, deployments) from the developer's active session. Status is visible in Agent View; a notification arrives on completion.
OpenAI Codex's cloud sandbox and Claude Code's background mode are primary examples, integrating naturally with CI/CD pipelines.

What Is Cursor for iOS? Control Coding Agents from iPhone and iPad (Composer 2.5, iOS 26+, Public Beta from June 29, 2026)
**[Cursor](https://cursor.com/) (by Anysphere) released its official iOS public beta on June 29, 2026** ([official blog](https://cursor.com/blog/ios-mobile-app) / [Changelog](https://cursor.com/changelog/ios-mobile-app) / [App Store](https://apps.apple.com/app/cursor/id6767085653) / [TechCrunch](https://techcrunch.com/2026/06/29/cursor-now-has-a-mobile-app-for-guiding-your-coding-agent-on-the-go/) / [9to5Mac](https://9to5mac.com/2026/06/29/cursor-releases-iphone-and-ipad-app-following-recent-acquisition-by-spacex/)).
**You can now drive Cursor's coding agents directly from iPhone and iPad** (iOS 26.0+ required). Available to all paid-plan subscribers as a public beta, with **75% off Composer 2.5 runs through July 5, 2026**.
**Main capabilities**:
- **Launch cloud / background agents** or **remote-control desktop-running agents** (with handoff between the two)
- **Voice input for task description**, **slash commands** to guide the agent
- **Push notifications + lock-screen Live Activities** when work is ready
- **Review generated demos, screenshots, logs, and videos**; annotate screenshots
- **Inspect diffs and merge PRs** from the phone
- **Model selection** across Composer 2.5, GPT (OpenAI), Claude (Anthropic), Gemini (Google), etc.
- **MCP integrations** — query Datadog logs, summarize Slack activity, etc.
**Strategic context**: this lands alongside the **$60B SpaceX acquisition option on Cursor** (referenced in our [Grok Build column](../columns/grok-build-xai-cli-coding-agent-2026-06)) and operationalizes the **"independent coding agents" thesis** of Cursor 2.0 (Oct 2025). Anthropic's Boris Cherny (Claude Code lead) is quoted saying **"I do most of my coding on my phone now"** (TechCrunch). Joins **Claude Code Mobile / Codex Mobile / GitHub Copilot Mobile** as the fourth major mobile coding-agent surface.
**Caveats**: public beta only, the Composer 2.5 promo ends July 5, 2026, no Android or Web yet, requires iOS 26.0+ (older iPhones cannot install), and large-codebase manipulation from mobile alone is still constrained.
