Coding Agents · Aider

Aider

Open-source AI pair programming in your terminal. It edits code in your local git repo and works with many LLMs (Claude, DeepSeek, OpenAI models and more).

Coding Agents · Anthropic

Anthropic's agentic coding tool. It reads your codebase, edits files, runs commands, works with git and connects to MCP servers. It runs in the terminal, with VS Code/JetBrains extensions, a desktop app and a web version too.

Editor Extensions · Cline

Cline

Open-source coding agent for VS Code (also JetBrains, a CLI and a desktop app). It edits files across your project, runs terminal commands and uses a browser, with Plan/Act modes and approval for every change unless you turn on auto-approve.

MCP Servers · Upstash

Context7

Pulls up-to-date, version-specific library documentation and code examples into your prompt, so the AI stops relying on outdated training data or made-up APIs.

Rules & Prompts · Cursor

Cursor Rules

Cursor's rules feature gives the Agent persistent instructions. Project rules are .mdc files in .cursor/rules, and there are also User Rules, Team Rules and plain AGENTS.md files.

MCP Servers · Figma

Brings design context from your Figma files into AI coding tools so they can generate code that matches your designs.

MCP Servers · Model Context Protocol

Filesystem MCP Server

Reference MCP server that lets an AI read, write, edit, move and search files and directories, restricted to the folders you allow.

MCP Servers · GitHub

GitHub MCP Server
