JetBrains Air

83/100freemiumexplicit relation

JetBrains Air is JetBrains' system for building software with AI agents: Air in IDEs (an Early Access plugin for running agents inside JetBrains IDEs), the Air app (a desktop client for local, Git worktree, Docker and cloud tasks), Air Teams (shared cloud environments and automations) and Air Governance (organization policies, AI credit limits and analytics). It runs Claude Agent, OpenAI Codex, Gemini CLI, Junie and ACP-compatible agents.

Cloud tasks and automations always spend JetBrains AI credits. Local tasks in the Air app use your own connected Claude, OpenAI or Google account or API key first, and spend JetBrains AI credits only when no own account is connected. JetBrains AI Pro costs $10/month (10 AI credits per 30 days) and AI Ultimate $30/month (35 credits); each credit equals $1, and purchased credits are valid for 12 months. For organizations, Air Governance has a free Basic plan, a Business plan at $20 per seat per month that adds AI policies, BYOK providers, model management, ACP agents and MCP servers, and an Enterprise plan on request. AI credits are billed separately from seats.Review →

Claude CodeAnthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and runs on current Claude models such as Opus 5.5 and Sonnet 5.5 for complex architecture work. Built for terminal-first developers.CursorCursor is an AI coding agent for building software, available as a desktop editor, a CLI and cloud agents that run in isolated VMs. Its Agent edits files, searches the codebase and runs terminal commands in Agent, Plan and Ask modes; Premium and higher tiers add Automations, Bugbot pull-request reviews and Origin code hosting. Sold within The X Subscription, it offers Cursor's own models (Grok and Composer), third-party models on Premium and above, and Privacy Mode on every plan.Google AntigravityGoogle Antigravity is Google's AI-powered agentic development platform, announced in November 2025 and expanded with Antigravity 2.0 at I/O 2026, that places autonomous AI agents at the center of software development. Distributed as both a VS Code-based desktop app and the new Antigravity CLI, it runs planning, implementation, and verification agents — backed by Gemini 3.1 Pro/Flash, Claude Sonnet/Opus 4.6, and GPT-OSS 120B — across editor, terminal, and browser.CodexCodex is OpenAI's coding agent for software development across the Codex app, editor, terminal, and cloud tasks. It helps write, review, debug, refactor, and automate code, with ChatGPT plan access for managed surfaces and API-key usage for CLI, SDK, and IDE workflows. The open-source CLI and SDK support local repository work, while cloud features add GitHub review, Slack/Linear integrations, worktrees, skills, MCP, and automations.VS CodeMicrosoft's free, open-source code editor that has become the most widely used development environment in the world. Lightweight but powerful, with built-in Git, integrated terminal, IntelliSense, debugger, and tens of thousands of extensions. Recent updates add Agent mode for delegating coding tasks to AI, Model Context Protocol (MCP) support, and Next Edit Suggestions. Native GitHub Copilot, remote development via SSH/containers/WSL, and a browser version at vscode.dev.CodeRabbitAI-powered code review tool that automatically analyzes pull requests and provides line-by-line feedback on code quality, bugs, security vulnerabilities, and best practices. Integrates with GitHub and GitLab as a bot that comments on PRs. Uses LLMs to understand code context and suggest improvements. Learns from your codebase patterns and team preferences. Supports all major programming languages. Reduces review cycle time while catching issues human reviewers might miss.GitHub CopilotAI-powered code assistant from GitHub and OpenAI that provides real-time code suggestions, completions, and chat-based help directly in your editor. Offers inline completions, a chat interface, an autonomous coding agent that can implement features from GitHub Issues, and AI code review with 60M+ reviews processed. Supports models from several providers. Works with VS Code, Visual Studio, JetBrains IDEs, Neovim, Xcode, and Eclipse. The benchmark AI pair programmer.Agent OrchestratorAgent Orchestrator manages fleets of parallel AI coding agents, each working in isolated git worktrees. It handles CI failures, code review comments, and pull request coordination while keeping humans involved for judgment calls. The current canonical repository is maintained under Untrivial AI.CodyAI coding assistant from Sourcegraph for large enterprise codebases. Uses Sourcegraph's code graph for deep cross-file reasoning with flexible model choice (Claude, Gemini, GPT). Features autocomplete, chat, inline editing, test generation, and OpenCtx providers (Jira, Linear, Notion, Google Docs).
