Autonomous AI software engineer that plans, codes, tests, and deploys complete software projects using its own sandboxed development environment with terminal and browser access.
Devin is an AI Coding autonomous software engineering agent developed by Cognition, a company founded in 2023 by a team with 10 International Olympiad in Informatics (IOI) gold medals and senior engineers from Cursor, Scale AI, Google DeepMind, Waymo, and Modal. Unlike inline coding assistants that suggest completions while a developer types, Devin operates as a fully autonomous agent: it receives a task description, plans an approach, writes code, installs dependencies, runs tests, debugs failures, and delivers reviewable pull requests — all inside its own sandboxed environment equipped with a code editor, terminal, and web browser.
Devin launched in March 2024 as an enterprise-only product at $500 per month per seat. In April 2026, Cognition reduced the entry price by 25x to $20 per month with a self-serve ACU (Autonomous Compute Unit) pay-as-you-go billing model, making autonomous agent capabilities accessible to individual developers and small teams for the first time. Team plans are available at $200 per month per seat with collaboration features, shared sessions, and admin controls, while Enterprise plans offer custom pricing with SSO, audit logging, RBAC, and compliance configurations including a government tier for regulated workloads.
