In their own words
Devin
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.
Refact.ai
Refact.ai is a free, open-source autonomous AI coding agent for software development. It provides real-time code completion, in-IDE chat and agent workflows that can plan, execute and deploy coding tasks while letting users preview and control the process. Chat supports natural-language questions, editing, debugging and code generation. Repository analysis, retrieval-augmented generation and codebase indexing provide project-aware context, and terminal access is available. The maker says it supports more than 25 programming languages. Plugins are listed for VS Code and JetBrains, with Visual Studio, Neovim and Sublime Text marked beta. Platforms include Windows, macOS, Linux, API, extension and self-hosted deployment. Local use can connect to configured providers or runtimes such as OpenAI, Anthropic, Gemini, Ollama, LM Studio and vLLM. The Free plan costs nothing for personal and hobby projects. Pro costs $10 a month for professional use. Hosted accounts and cloud features are being retired.
