Cognition's Devin for Terminal brings the full autonomous coding power of Devin to your command line. Unlike the browser-based Devin interface, the Terminal version lets you trigger complex engineering tasks from your CLI and continue working — or close your laptop entirely — while Devin executes in the cloud in a persistent session. The key innovation is bidirectional handoff: you initiate locally, Devin Cloud takes over with a persistent execution environment that survives network drops, sleep cycles, and machine switches. This bridges the "last mile" problem of autonomous coding tools — the frustrating requirement to stay connected while a long job runs. Launched April 29, 2026, Devin for Terminal is free to use and signals Cognition's push toward deeper developer workflow integration beyond browser-only interfaces. The clear implication: the future of coding agents isn't a tab you keep open, it's infrastructure that runs in the background.

Marky is a minimal macOS markdown viewer designed specifically for the agentic coding workflow — where an AI agent is constantly writing and updating documentation, and you need to review it instantly without switching to a browser or IDE. Built by @grvydev using Tauri and Rust, it weighs under 15 MB and launches nearly instantly. The tool is CLI-first: `marky README.md` opens the file with live reload, so edits appear in real time. Features include Cmd+K fuzzy search across all open documents, full Mermaid diagram rendering, Shiki syntax highlighting with multiple theme options, and table of contents navigation. It's intentionally not a note-taking app — it's a viewer, which keeps it fast and focused. The timing matters: as AI coding agents generate more documentation, architecture diagrams, and spec files during long sessions, having a dedicated lightweight viewer becomes genuinely useful. Reading agent output in a terminal or GitHub preview is friction. Marky eliminates that friction without adding bloat. Show HN received 69 points, suggesting the niche is real.
Reviewer scorecard
“The 'keep working when you close your laptop' pitch is exactly right. I've lost countless Devin sessions to network hiccups. Persistent cloud-backed execution from my terminal is the architecture I've wanted since day one. This is how async development should work.”
“Under 15 MB, Tauri/Rust, instant open, live reload — this is the tool I didn't know I needed for reviewing agent-generated docs. The Cmd+K fuzzy search across documents is the right power-user feature. Exactly the kind of focused tool that's worth having in your dock.”
“Devin's benchmarks have always been impressive; real-world results sometimes less so. A terminal wrapper doesn't change the underlying model's limitations — it just makes them more convenient to encounter. And Cognition still hasn't fully addressed cost transparency on longer sessions.”
“Your IDE's preview panel and GitHub both render markdown fine. Marky solves a real but minor pain point — justifying a dedicated app for viewing markdown is a stretch for most developers. macOS-only also limits who can even use it.”
“Devin for Terminal is a preview of where all coding tools are heading: invisible infrastructure that executes while you're away. The terminal is the right interface — it meets developers where they already live. Expect every major coding agent to have a persistent CLI within 6 months.”
“Agentic workflows generate a constant stream of living documents — specs, changelogs, architecture decisions. A dedicated high-performance viewer for that output is the right primitive. Marky is small now but points at a category: real-time agent output viewers for humans in the loop.”
“Terminal tools aren't for most creators — but for technical creatives who build their own tools, persistent agent execution is a genuine unlock. Kick off a refactoring job, go design something, come back to a finished PR. That's a workflow shift.”
“Clean, fast, focused. The Mermaid diagram support means architecture docs actually render beautifully instead of showing raw text. For reviewing AI-generated technical writing, having a beautiful reader matters for catching errors in structure and flow.”
