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.

pi-mono is an open-source TypeScript monorepo by solo developer Mario Zechner (creator of libGDX) that bundles everything you need to build and ship AI agents: a unified LLM API layer supporting OpenAI, Anthropic, Google, and any OpenAI-compatible endpoint; a full coding agent CLI (Pi) with extensions, skills, and prompt templates installable as npm packages; terminal UI and web component libraries for building chat interfaces; a Slack bot; and CLI tooling for spinning up vLLM GPU pods. The unified API handles automatic model discovery, provider configuration, token and cost tracking, and mid-session context handoffs between different models. This means you can start a conversation with Claude, hand it off to Gemini mid-session, and continue — context intact. Pi the coding agent is intentionally minimal and extensible via TypeScript, positioning it against Claude Code and Codex as a hackable alternative. With 31.8k stars and 3.5k forks, this is a solo project that's clearly resonating. It's not a company — it's a developer scratching their own itch and open-sourcing the full stack.
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.”
“The mid-session model handoff is a genuinely useful primitive — start cheap with a fast model for exploration, hand off to a smarter model when you hit a hard problem, without restarting context. The vLLM pod tooling bundled in means this covers the full dev-to-deploy loop for teams running their own inference.”
“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.”
“This is a solo project actively undergoing 'deep refactoring.' 31k stars is impressive but doesn't guarantee API stability — you may build on an interface that changes underneath you. The breadth is also a red flag: coding agent, TUI, web components, Slack bot, and vLLM ops from one developer is a lot to maintain indefinitely.”
“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.”
“The pattern of unified LLM abstraction layers is becoming foundational infrastructure — whoever wins the 'standard API for agents' race becomes the JDBC of AI. pi-mono is a strong contender because it's actually being used by thousands of developers, not just theorized about in a whitepaper.”
“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.”
“The web component library means you can drop a fully functional AI chat interface into any web project without rebuilding from scratch. For indie creators who want AI features without a full backend, that's genuinely useful scaffolding.”
