Guided scenario
Private & open-source AI coding tools
Some teams can't send source code to a third-party model, whether for IP, regulation, or client contracts. This shortlist ranks AI coding assistants, agents, and editors by how much control you keep: open-source code, support for fully local models, bring-your-own-model, and self-hosting. Also weigh editor integration, how well each handles your languages and codebase size, and per-seat versus token pricing.
Aider
aider.chat
Aider is an open-source AI pair-programming agent that runs in the terminal, editing files in a local git repository through any of many model providers, including fully local models.
Amazon Q Developer

Amazon Q Developer is AWS's AI coding assistant, offering inline completion, chat, and agent capabilities with first-party integration into AWS services and consoles.
Augment Code
www.augmentcode.com
Augment Code is an AI assistant and agent built around a context engine for large, established codebases, indexing the full repository so suggestions and agent edits respect existing patterns.
Claude Code
claude.com/claude-code
Claude Code is Anthropic's AI coding agent, built for multi-file agentic work: it takes a goal and plans and completes changes across a codebase rather than suggesting code line by line.
Cline
cline.bot
Cline is an open-source AI coding agent that runs as a VS Code extension, planning and executing multi-file changes with human-in-the-loop approval of each step.
Codex
openai.com/codex
Codex is OpenAI's delegation-first coding agent: tasks are handed off and completed autonomously, in the cloud or locally via its CLI and IDE extension.
Continue
continue.dev
Continue is an open-source AI code assistant that runs inside VS Code and JetBrains IDEs, letting developers connect any model provider or run fully local models.
Cursor
cursor.com
Cursor is an AI-first code editor rather than a plugin: a full editor built around fast, repository-aware AI editing that blurs the line between assistant and agent.
Devin
devin.ai
Devin, from Cognition, is an autonomous AI software engineer: tasks are delegated whole and Devin plans, edits, tests, and opens pull requests on its own.
Gemini Code Assist
codeassist.google
Gemini Code Assist is Google's AI coding assistant, providing inline completion and chat across popular IDEs with deep hooks into Google Cloud services.
GitHub Copilot
github.com/features/copilot
GitHub Copilot is an AI pair-programming assistant built into the GitHub ecosystem, suggesting code inline as developers type across major IDEs.
