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.

Hopper, from YC S24 startup Hypercubic, is the first agentic development environment purpose-built for mainframe systems. It lets AI agents navigate TN3270 terminals autonomously, write and submit JCL jobs, monitor JES output, debug failed jobs by analyzing spool data, query VSAM datasets, compile and run COBOL code, and manage CICS transactions—all via natural language prompts. Tasks that traditionally took mainframe specialists hours of manual TN3270 navigation can now be expressed as a single instruction. The technical challenge here is real: mainframes don't have nice REST APIs or modern dev tooling. They run on green-screen terminal protocols from the 1970s, and the humans who know how to operate them are retiring faster than they can be replaced. Hopper essentially wraps the entire mainframe interaction surface in an agent-friendly interface, translating intent into the arcane sequences of keystrokes and JCL that mainframes actually require. The product is free for individual developers (all core features, macOS/Windows/Linux) with Enterprise pricing for SSO, on-prem deployment, and SOC 2 reports. Hypercubic's team includes alumni from Cognition, Apple, and Windsurf. Given that mainframes still process an estimated $3 trillion in daily commerce and the COBOL developer shortage is acute, Hopper is targeting a genuinely underserved market with unusual urgency.
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.”
“This solves a real crisis. I've watched financial institutions pay six-figure consultant fees for tasks that Hopper demos suggest could be automated in minutes. If it's reliable on diverse JCL and CICS environments, this is immediately commercial.”
“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.”
“Mainframe environments at major banks are extraordinarily heterogeneous—custom RACF configurations, vendor-specific CICS extensions, and decades of undocumented JCL conventions. An agent that confidently submits the wrong job in a production batch environment could be catastrophic.”
“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 $3 trillion in daily mainframe commerce has been a black box to AI modernization. Hopper is the Rosetta Stone moment—once there's an agent-friendly interface to legacy systems, every other AI tool in the stack becomes accessible to that infrastructure.”
“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.”
“There's something poetic about AI agents handling COBOL—the language written by Grace Hopper, now managed by a tool named after her. For teams modernizing legacy fintech systems, this is the missing piece.”
