Agent Tools
7 curated agent tools for AI coding — compare what each one does, how it's priced, and where it fits in an AI-assisted development stack.
Amp
Agentic coding tool, independent of Sourcegraph since December 2025: a CLI plus apps for the web, Mac, iPhone, and iPad, tuned for frontier-model coding.
Devin
Cognition's autonomous AI software engineer that works in its own cloud workspace with an editor, terminal, and browser.
Factory
Factory is an agent-native software development platform whose Droids plan, write, test, and ship code from the terminal, IDE, and web with org context.
Goose
Open-source, on-machine AI agent, originally from Block and now an Agentic AI Foundation project — MCP-native and model-agnostic, with a CLI and desktop app.
Jules
Google's asynchronous coding agent: it clones your GitHub repo into a cloud VM, proposes a plan built with Gemini, and opens a pull request once you approve.
OpenHands
Open-source autonomous AI software-development agent (formerly OpenDevin) — writes code, runs commands, and browses the web in a sandbox.
Swe Agent
Open-source autonomous coding agent from Princeton/Stanford that turns an LLM into a software engineer to fix real GitHub issues.
