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 MIT-licensed monorepo by developer Mario Zechner (the creator of libGDX) containing a suite of packages for building LLM-powered agents: a unified multi-provider API (OpenAI, Anthropic, Google), an interactive coding agent CLI, an agent runtime with tool calling, TUI and web UI libraries, a Slack bot integration, and CLI tooling for deploying vLLM pods on GPU infrastructure. The design philosophy is deliberate minimalism — each package is self-contained, composable, and avoids abstractions that obscure what the LLM is actually doing. The pi-coding-agent is the flagship: it takes a task, breaks it into steps, runs shell commands and edits files, streams its reasoning to a rich terminal UI, and confirms destructive actions before executing. It's closer in spirit to a hands-on CLI coding partner than a one-shot code generator. With 32,800 GitHub stars, Pi-Mono has real traction in the developer community — particularly among engineers who are tired of opaque agent frameworks and want to own their toolchain. The "share your sessions publicly to improve training data" encouragement is an interesting contribution loop that distinguishes it from purely proprietary tools.
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 unified LLM provider API alone is worth bookmarking — switching between Claude, GPT-4o, and Gemini without rewriting your agent logic is genuinely useful. The coding agent's step-by-step terminal UI is also much easier to debug than black-box agent frameworks.”
“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.”
“The monorepo structure means you're taking on a lot of footprint for each component you actually need. Mario is a talented developer but a one-person project at this scope carries real maintenance risk — don't build production workflows on an unstable package graph.”
“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 'share sessions for training data' concept is quietly subversive — it turns every Pi-Mono user into an inadvertent AI trainer. Open-source agent toolkits that build community feedback loops into their design are going to compound faster than closed systems.”
“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.”
“This is firmly a developer tool — the TUI and web components are functional but not approachable for non-technical users. Unless you're comfortable reading TypeScript and configuring LLM API keys, the setup cost isn't worth it for content workflows.”
