アジェンタ

Agenta

An open-source (MIT) workspace for building and running AI agents. Build agents by chatting, connect them to your apps, and run them in the background with approval flows, tracing, and version history. Positioned as "the open-source workspace for your agents," it supports 1,000+ integrations (MCP/Composio) and is model-agnostic. Self-hosting is free, with a cloud version available.

カーソル

Cursor

Cursor is an AI coding agent (AI code editor) from Anysphere. A VS Code-based desktop app (macOS / Windows / Linux), it takes natural-language instructions and has an agent that understands your codebase handle planning, implementation, and fixes. You can choose its in-house Composer model, Grok, or frontier models from various providers, and it supports running multiple tasks in parallel, cloud agents, agentic code review by Bugbot, MCP, skills, and hooks, and privacy mode. A Cursor CLI and iOS app are also available. Pricing includes Hobby free, Pro $20, Pro+ $60, Ultra $200, and Teams $40 (per user, per month), among others.

クライン

Cline

Cline is an open-source AI coding agent that runs inside the editor and terminal you already use (built by Cline Bot Inc., Apache 2.0). You can use the same agent from a VS Code extension, JetBrains, a CLI, or an SDK, and with Plan/Act it separates planning from execution so you approve as it goes, autonomously handling multi-file edits and command execution. It supports every provider — Claude, GPT, Gemini, local models and more — and with bring your own key there is no vendor lock-in. The extension and CLI are open source and free for individuals (the only cost is usage-based model inference). Used by more than 8 million developers, with 66,000 GitHub stars.

ギットハブ コパイロット

GitHub Copilot

GitHub Copilot is an AI coding assistance service provided by GitHub (a Microsoft subsidiary). In addition to code completion, it includes an agent mode that implements autonomously, a cloud agent that works in the cloud, automatic PR review, and the Copilot CLI. It can be used in VS Code, JetBrains, GitHub, the terminal, and more, and you can choose from major models such as Claude, GPT, and Gemini. For individuals there is the free Free plan, Pro $10, Pro+ $39, and Max $100; for businesses there are Business $19 and Enterprise $39 (per user/month, on a GitHub AI credit system).

グーグル エーアイ スタジオ

Google AI Studio

Google AI Studio is Google's developer platform to try the Gemini models in the browser, build and deploy AI apps, and get a Gemini API key. It's organized around Build (app generation), Chat, Stream, and Generate Media (image/video/audio), and offers the Gemini 3 family, Nano Banana image, Veo video, and more. AI Studio itself is free; the API is usage-based with a free tier. Note: on the free tier input is used to improve products; on the paid tier it is not.

マストラ

Mastra

An open-source AI agent development framework written in TypeScript. It integrates Agents/Tools/Workflows/RAG/Memory/Evals/Observability and lets you switch among LLMs like OpenAI, Anthropic, and Google Gemini. Under "build, observe, and improve," it suits building and running agents that run for days. The framework is free (OSS), with a hosted Mastra Platform available.

ジュニー

Junie

JetBrains' autonomous AI coding agent integrated into JetBrains IDEs. From a natural-language instruction it autonomously plans, edits multiple files, runs commands and tests, leveraging deep IDE context like the index and debugger. GA since June 2026. Supports major IDEs including the free IntelliJ IDEA Community, with selectable models (Claude 4.5, Gemini 2.5, etc.). Used via the JetBrains AI subscription (Free/Pro $10/Ultimate $30, credit-based).
