Astropad Workbench is a remote desktop application from the makers of Luna Display and Astropad Studio, redesigned from the ground up for the AI agent era. The use case: developers running AI coding agents, terminal sessions, or automation scripts on headless Mac Minis 24/7 need a way to monitor and interact with those agents from anywhere. Workbench provides low-latency remote desktop access from iPhone or iPad using Astropad's proprietary LIQUID protocol, which the company claims outperforms VNC and RDP on high-resolution displays. What differentiates Workbench from generic remote desktop tools is its agent-management UX: voice dictation for sending prompts to terminal windows, Apple Pencil support for annotating screenshots, touch-optimized keyboard shortcuts for common agent tasks (approve/reject, cancel, restart), and a quick-launch widget for connecting to frequently-used machines without opening the app. The companion Mac app acts as a low-overhead server daemon that starts on boot and exposes the display to paired iOS devices. Astropad Workbench launched on Product Hunt with 104 votes and coverage from MacRumors and 9to5Mac. At $10/month or $50/year (20 min/day free), it's positioned as a developer productivity subscription rather than an enterprise remote-access solution. The timing is deliberate: as Mac Minis become the preferred agent compute platform for indie developers, Astropad is betting that agent babysitting is a daily task that deserves its own dedicated tool.

Grok Build

Grok Build is xAI's answer to Claude Code, Codex CLI, and Gemini CLI — a terminal-native, local-first coding agent that runs all code on your machine with nothing transmitting to xAI's servers. The headline feature: up to 8 parallel agents working on the same codebase simultaneously, each taking a different approach, letting you compare results. The "Arena mode" is distinctive: it pits multiple agents against the same task and presents the outputs side-by-side, letting you pick the winner. GitHub integration, a credits system, and an optional web UI round out the feature set. Currently in early access beta gated to Grok Heavy subscribers, with Elon Musk signaling a wider launch imminently. It powers grok-4.20-multi-agent under the hood — a model version specifically tuned for multi-agent coordination. Whether the 8-parallel-agent architecture produces meaningfully better code than a single focused agent remains to be benchmarked, but the concept is genuinely novel in the CLI agent space.
Reviewer scorecard
“If you're running agents on a headless Mac Mini, this fills a real gap. The voice dictation-to-terminal feature alone saves constant context-switching. LIQUID protocol latency is noticeably better than Screens or Remotix on the same network. At $10/month it's easy to justify if you spend more than 2 hours a week babysitting agents.”
“8 parallel agents tackling the same coding task is a fascinating approach — it's basically tournament selection applied to code generation. If the arena mode lets me specify different constraints for each agent (test coverage vs. speed vs. readability), this could become a genuine creative tool for complex architecture decisions.”
“This is a premium wrapper on remote desktop technology that has been free for decades. SSH + tmux handles 90% of agent monitoring needs. The 20-minute free tier is aggressively limiting, and the $10/month bet assumes you'll always be near an iPhone or iPad — which developers with multiple monitors at a desk often won't be.”
“It's still on a waitlist. Musk has said 'next week' about this launch multiple times across multiple weeks. The 'local-first, nothing leaves your machine' claim needs independent audit before trusting it for professional codebases. Approach with appropriate caution until it has a real public release.”
“Remote agent management from mobile is a genuine paradigm shift in how we relate to compute. As agents handle longer-horizon tasks, the supervision interface becomes as important as the agent itself. Workbench is an early bet on what 'agent oversight UX' looks like — and Apple's ecosystem is the right place to build it first.”
“The multi-agent arena pattern is prescient — the future of AI-assisted development is not one agent helping you, it's a tournament of agents generating approaches and humans curating outputs. Grok Build is sketching what software development will look like when compute is effectively free.”
“Being able to review and approve agent outputs from an iPad while away from your desk is genuinely freeing. The Apple Pencil annotation for screen review is a nice touch — annotating a generated design or document in-context beats typing corrections in a chat interface.”
“Even for non-developers, the arena concept translates well. Being able to prompt for a landing page, a marketing brief, or a piece of code and see 8 simultaneous interpretations is a genuinely powerful creative workflow. The 'pick the winner' UX pattern is intuitive and low-friction.”
