aider vs SWE-agent
Terminal coding assistant and repository issue agent compared
aider is a terminal-based pair-programming tool for making code changes with cloud or local models. SWE-agent gives models tools to attempt repository issue fixes and is oriented toward research and configurable tasks; its maintainers recommend mini-SWE-agent for new use.
aider: Pair Program with AI in Your Terminal
Aider is a terminal-based AI coding assistant that works with existing repositories or new projects. It helps developers make code changes with cloud or local language models while keeping edits and version control in their workflow.
SWE-agent: Use Language Models to Fix GitHub Issues
SWE-agent gives a language model tools to work on real software repositories, including diagnosing and attempting to fix GitHub issues. It is designed for software engineering research and configurable coding tasks, though its maintainers now recommend mini-SWE-agent for new use.

Key differences
- aider is built around a developer-directed terminal workflow, while SWE-agent can start an automated fixing attempt from a GitHub issue.
- aider supports more than 100 programming languages and maps repositories for context; SWE-agent emphasizes repository tools, YAML configuration, and SWE-bench workflows.
- aider supports hosted and local models as well as web-chat copy-and-paste workflows; SWE-agent lets users select a model, with GPT-4o and Claude Sonnet 4 named as examples.
- aider uses the Apache-2.0 license, while SWE-agent uses the MIT license.
- aider is aimed at developers working in a codebase; SWE-agent is aimed at software engineering research, agent evaluation, custom coding tasks, and EnIGMA cybersecurity challenges.
- Both are Python projects and are not archived, but SWE-agent's maintainers recommend mini-SWE-agent for new use.
Choose aider if you…
- want a terminal-based assistant for directing and reviewing code changes in an existing repository or a new project.
- need repository mapping, Git integration, or help running linters and tests after edits.
- prefer to work with cloud or local models, or use a model through its web chat interface.
Choose SWE-agent if you…
- want to study how language models use repository tools to attempt GitHub issue fixes.
- need configurable workflows for SWE-bench evaluation or custom coding tasks.
- want to explore the documented EnIGMA mode for cybersecurity challenges and can use the recommended 0.7 version.
