**[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.

**[Grok Build](https://x.ai/cli)** is xAI's official CLI coding agent, **released as early beta on May 14, 2026** ([official](https://x.ai/cli) / [Changelog](https://x.ai/build/changelog) / [npaka's Japanese note write-up](https://note.com/npaka/n/nd813d073196e)). Alongside Claude Code, Codex CLI, Gemini CLI, and [agmsg](../columns/agmsg-cross-agent-messaging-cli-ai-2026-06), Grok Build is **xAI's entry in the CLI coding-agent space**. Its key differentiators are **up to 8 parallel sub-agents isolated in separate Git worktrees**, a Plan-Review-Approve workflow, **ACP (Agent Client Protocol) + MCP servers**, and **local execution** (air-gap-compatible). **Model & pricing**: - Internal model: **grok-build-0.1** (256K context, API rates **$1.00/M input, $2.00/M output**); **Composer 2.5** for SuperGrok / X Premium+ - SWE-Bench Verified **70.8%** (vendor-reported; ~17 pts behind Claude Opus 4.7 87.6% and GPT-5.5 88.7%) - Access gated to **SuperGrok Heavy ($300/mo; $99/mo introductory promo)**, SuperGrok, and X Premium+ **Install**: `curl -fsSL https://x.ai/cli/install.sh | bash`. **Integrations**: AGENTS.md / plugins / hooks / Skills / **Plugin Marketplace (MongoDB / Vercel / Sentry / Chrome DevTools / Cloudflare / Superpowers)** / Agent Dashboard / `/goal` long-running autonomous mode / headless `-P` flag for CI/CD. **Strategic context**: the February 2026 **SpaceX × xAI merger**, SpaceX's disclosed **$60B acquisition option on Cursor**, and Composer 2.5 currently training on **Colossus**, xAI's in-house supercomputer — Grok Build sits inside an unusually vertically-integrated stack. **Caveats**: roughly **15× the price** of Claude Code / Codex CLI bundles ($20/mo); ~17 pts behind on SWE-Bench Verified; no IDE integration (terminal only); flagship demos such as Arena Mode remain unshipped. Where it wins: **Git-worktree parallelism, xAI ecosystem integration, and local execution**.
