Devin vs GitLab Duo Code Suggestions

Devin is a coding tool that Cognition describes as an autonomous software engineer: it can plan, write, test and ship production code. Its workflows include migrations, refactors, documentation, scheduled chores, issue triage, bug fixes, testing and performance optimization. Devin runs in the cloud or on a user's machine, tests in its own browser and works toward a pull request ready to merge; larger tasks can be divided among parallel cloud agents. For local work, Devin CLI runs in the terminal on macOS, Linux and Windows, while Devin Desktop provides an IDE with syntax highlighting, autocomplete, debugging tools, agent fleet management and shared context. Listed capabilities also include code completion, chat assistance, codebase indexing and terminal access. Integrations and workflows involve tools including GitHub, Linear, Slack, Teams, Datadog, Sentry, Jira, Confluence, AWS, Google Drive and PostgreSQL. The free plan has limited usage; Pro costs $20 a month and Max costs $200 a month. Paid-plan allowances refresh daily and weekly, with extra usage available at API pricing.

GitLab Duo Code Suggestions provides code completion and generation in supported editors. It can complete code blocks, help define function logic, generate tests, and suggest common patterns such as regular expressions. Supported editors include Visual Studio Code, GitLab Web IDE, Microsoft Visual Studio 2022, JetBrains IDEs, Neovim, and Eclipse; GitLab lists more than 14 supported languages, including C++, C#, Go, Java, JavaScript, Python, Rust, and TypeScript. The feature is available on the GitLab.com Free tier with GitLab Credits, and self-managed GitLab instances can use it through a secure connection to GitLab.com. GitLab says it does not train generative AI models and that private, non-public customer code stored in GitLab is not training data. Suggestions are scanned to help prevent sensitive information such as API keys or passwords from being shared. GitLab warns that high demand may degrade performance or cause unexpected downtime. GitLab Duo Pro is listed at $19 per user per month.
