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.

Pretty Fish is a free, open-source Mermaid diagram editor with live preview, 5 built-in themes, multi-page workspaces, and one-click SVG/PNG export. It works offline as a Progressive Web App (PWA) and requires no account, no login, and no installation. It supports all 14+ Mermaid diagram types including flowcharts, sequence diagrams, Gantt charts, entity-relationship diagrams, and Git graphs. The editor includes syntax highlighting, auto-completion, instant error feedback, and a clean split-pane layout. The multi-page workspace lets you manage entire diagram projects in a single session. Export quality is excellent — SVG output is clean and scaling-ready for use in presentations, docs, or design systems. Pretty Fish hit Hacker News front page today with 128 points and has the makings of the go-to Mermaid editor for developers who generate diagrams from AI-assisted documentation workflows. With LLMs increasingly generating Mermaid syntax in their outputs, having a polished renderer and editor matters more than ever.
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.”
“The official Mermaid live editor is clunky and slow. Pretty Fish loads instantly, works offline, and the multi-page workspace means I can manage all my architecture diagrams in one place. Bookmarking this immediately as my default Mermaid editor.”
“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.”
“It's a genuinely nice editor but it's solving a niche problem — most devs who need Mermaid diagrams already use VS Code extensions or embed them in Notion. And with no backend, there's no collaboration or sharing story, which limits its use in team workflows.”
“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.”
“As AI tools increasingly output Mermaid syntax to explain architectures and flows, the need for a great rendering environment grows. Pretty Fish positions itself at the intersection of AI-generated diagrams and human editing — that's a well-timed niche.”
“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.”
“Five beautiful themes and clean SVG exports mean I can finally use Mermaid diagrams in client-facing presentations without them looking like developer scratch notes. This is the Mermaid editor I've always wanted and the zero-friction setup seals it.”
