Clide is a native macOS terminal app that rethinks the terminal experience for the agent era. Instead of bolting AI onto an existing terminal, Clide builds around it: an AI pair-developer lives in a side panel alongside a customizable grid of up to 6×6 terminal panes. The AI can read terminal scrollback, preview files, and execute commands into any pane—with user confirmation—making it a genuine collaborator rather than a glorified autocomplete. Built with SwiftTerm, AppKit, and SwiftUI (explicitly not Electron), Clide is genuinely native—fast, memory-efficient, and system-integrated. Drag files from Finder into the AI chat, use the screenshot HUD to share visual context, speak commands via voice input, and rely on workspace memory that persists across sessions. Zero telemetry. Free. What separates Clide from tools like Claude Code or Cursor is its terminal-centric model: rather than AI owning the editor and calling a shell, Clide keeps the shell primary and lets the AI reach into it. For server-side developers, sysadmins, and anyone who actually lives in a terminal, this architecture is more natural and less footprint-heavy than spinning up a full IDE for AI assistance.

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
“Clide nails the architecture: terminal-first, AI as assistant rather than owner. The native SwiftUI build means it's fast and doesn't eat 4GB of RAM like Electron alternatives. Grid panes plus agent control is exactly what I want for complex multi-process debugging sessions.”
“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.”
“Day-one Product Hunt launch with 11 followers means this is extremely unproven. The grid + AI concept is compelling but implementation bugs in a terminal app can destroy your work. Wait for a few months of community testing before trusting it with production servers.”
“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.”
“The terminal isn't going away—it's getting AI co-pilots. Clide represents a category of tools that meet systems developers where they already work rather than pulling them into new IDEs. Native, agentic, terminal-first: this is what the shell looks like in 2026.”
“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.”
“Voice input, drag-and-drop files, screenshot sharing into the AI context—Clide is thoughtfully designed for humans who actually use terminals. The grid layout alone would make it worth trying. Free with zero telemetry is a bonus.”
“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.”
