**[Mosaic (mosaic.inc)](https://mosaic.inc/) is a desktop tool that runs multiple AI coding agents ([Claude Code](https://claude.com/product/claude-code) / Codex / OpenCode) in parallel from a single UI**, and on top of that offers **"SHARED CONTROL" — a rare feature in 2026 that lets multiple people live-edit a single Claude Code session together**. **The core of SHARED CONTROL**: spin up a session, a teammate joins the same terminal, and **you both see each others cursors, prompts, and output in real time** — genuinely shared control, not screen-share theater. The experience of Google Docs or VS Code Live Share, applied to a Claude Code session. Use cases (see the standing [request in Anthropic issue #60082](https://github.com/anthropics/claude-code/issues/60082)): pair programming, team debugging, onboarding, live review, and division of labor (Ali refactors the auth middleware while Shubham adds the rate-limit test — same session). **Parallel-ops layer**: each agent gets a **Git-worktree-isolated workspace**, and 5-10 agents can develop different branches / features concurrently with zero file collisions or state interference. **Position**: in the rapidly maturing late-2026 parallel-Claude-Code market, Mosaic competes with **[Conductor](https://www.ycombinator.com/companies/conductor) (YC, Mac-native)**, **[Superset](https://superset.sh/) (three ex-YC CTOs, 10+ concurrent)**, **[Herdr](../columns/herdr-terminal-agent-multiplexer-2026-07) (terminal-native, Rust)**, and Product-Hunt entries like [Claudy](https://www.producthunt.com/products/claudy) / [Multi-Claude](https://www.producthunt.com/products/multi-claude) — its distinctive differentiation is **real-time SHARED CONTROL**. Target users: solo developers, startup CTOs, staff engineers, plus **teams that want pair programming and live review with AI agents in the loop**. Combined with [Command Code taste-1 learning](../columns/commandcode-taste-1-personalized-coding-agent-2026-07), [the grill-me skill](../columns/grill-me-agent-skill-2026-07), and [Crit.md HITL review](../columns/crit-md-local-first-agent-review-2026-07), it forms a **"parallel × personalized × thoroughly reviewed × real-time collaborative" late-2026 AI dev stack**.

**[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**.
