Our picks from the AI coding landscape. Every tool here is one we have used, evaluated, or closely follow. Opinionated, not exhaustive.
AI Coding Agents
6Terminal-native coding agents and assistants
Claude Code
Anthropic's agentic coding tool. Lives in your terminal, understands your codebase, executes tasks through natural language. The one we built ClaudePedia to document.
GSD 2
A heavily modified Pi Code fork with GSD embedded. Meta-prompting, context engineering, and spec-driven development: agents work autonomously without losing the big picture.
OpenCode
Powerful AI coding agent for the terminal. Multi-model support, clean TUI. Pioneered many patterns others adopted.
Kilo Code
All-in-one agentic engineering platform. #1 coding agent on OpenRouter with 1.5M+ users and 25T+ tokens processed.
Gemini CLI
Google's open-source AI agent for the terminal. Brings Gemini directly to your command line with MCP support and 1M token context.
Codex CLI
OpenAI's lightweight coding agent for the terminal. Written in Rust for speed.
AI-Native IDEs
3Integrated development environments with built-in AI agents
Antigravity
Google's agentic development platform. Agent-first IDE with a Manager Surface for spawning and orchestrating multiple agents across workspaces. Free in public preview.
Windsurf
AI-powered IDE by Codeium. Deep codebase understanding with Cascade, their agentic flow engine.
Cursor
The AI code editor that started the agentic IDE category. Composer mode, multi-file editing, strong model support.
Agent Frameworks
10Libraries and platforms for building AI agents and pipelines
DeepAgents
Agent harness built with LangChain and LangGraph. Planning tool, filesystem backend, subagent spawning: handles complex agentic tasks out of the box.
LangGraph
Build resilient language agents as graphs. Stateful, multi-actor workflows with cycles, persistence, and human-in-the-loop.
LangChain
The agent engineering platform. Composable chains, tool use, retrieval, memory: the foundation everything else builds on.
CrewAI
Role-based multi-agent orchestration. Agents take on personas (researcher, writer, etc.) and collaborate with minimal boilerplate. Native MCP and A2A support.
OpenAI Agents SDK
Official OpenAI framework for multi-agent workflows. Lightweight, built-in MCP tool integration, persistent sessions, and realtime voice agents.
Claude Agent SDK
Wraps the Claude Code CLI as a programmable SDK. Bidirectional interactive conversations, custom tools and hooks as functions. Everything Claude Code can do, available programmatically.
Google ADK
Google's official Agent Development Kit. Code-first, multi-language (Python/Go/TS/Java). Optimized for Gemini but model-agnostic. Built-in evaluation and deployment tools.
Vercel AI SDK
Provider-agnostic TypeScript toolkit from the Next.js creators. 20M+ monthly downloads. Works with React, Svelte, Vue, Angular. The standard for AI-powered web apps.
Pydantic AI
Type-safe agent framework built on Pydantic. Leverages Python's type system to catch agent logic errors at dev time. The Pythonic way to build AI agents.
Semantic Kernel
Microsoft's enterprise-grade AI orchestration SDK. Multi-language (C#/Python/Java). Core of the Microsoft Agent Framework. Strong Azure and Copilot integration.
Tools
7Standalone CLI tools and utilities that enhance AI coding agents
RTK
Rust Token Killer. CLI proxy that rewrites dev commands for 60-90% token savings. Transparent hook-based usage, zero friction.
ccusage
Analyze Claude Code token usage and costs from local JSONL logs. Daily, monthly, and session reports with per-model breakdowns and 5-hour billing window tracking.
ccstatusline
Customizable status line for the Claude Code CLI. Displays model, git branch, token usage, and session metrics with Powerline themes.
Repomix
Packs an entire repository into a single AI-friendly file for LLM context windows. Tree-sitter compression (~70% token reduction), token counting, and MCP server.
CMUX
Native macOS terminal with vertical tabs, split panes, and notifications designed for running multiple AI coding agents in parallel.
Warp
AI-powered terminal built in Rust with GPU acceleration. Command suggestions, agentic workflows, and 700K+ developers. The terminal reimagined for AI.
Ghostty
Fast, cross-platform terminal by Mitchell Hashimoto (HashiCorp). Written in Zig with platform-native UI and GPU acceleration. 50K stars.
AI Design Tools
3Design-to-code tools and AI-powered visual editors
Pencil
AI-native vector design tool with MCP integration. Design-as-Code: turn prompts into UI directly on the live canvas.
Google Stitch
Google's AI design tool. Connects to your UI designs and generates production-ready code.
Figma
The collaborative design platform. AI features, dev mode, and MCP server support make it the bridge between design and code.
