GitHub (Microsoft) Closed source Visit Website Docs Download Share X Facebook Reddit Telegram Bluesky Email The most widely deployed AI coding assistant. Inline completions, Chat, agent mode, an autonomous coding agent that opens PRs from issues, and agentic code review — integrated across VS Code, JetBrains, Visual Studio, Neovim, and Xcode. Multi-model: GPT-5.4, Claude Sonnet 4.6 and Opus 4.7, Gemini 2.5 Pro, and more. ## + Pros - Deepest GitHub integration — PRs, issues, Actions, code review, and Copilot all in one platform - Available across the widest IDE surface: VS Code, JetBrains, Visual Studio, Neovim, Xcode, Azure Data Studio - Async coding agent handles full issue-to-PR workflows autonomously in GitHub Actions - Copilot CLI brings agent workflows directly to the terminal with specialized sub-agents - Enterprise-grade: SOC 2, IP indemnity, SSO, RBAC, private model fine-tuning, admin policy controls - Multi-model: GPT-5.4, Claude Sonnet, Gemini 2.5 Pro — user-selectable per session - Free tier available with 2,000 inline suggestions and 50 premium requests per month ## − Cons - IDE extension approach — no standalone AI-native editor, relies on host IDE - Agent mode less autonomous than Cursor or Claude Code on complex multi-step tasks - Individual plan sign-ups paused (Apr 2026); moving to usage-based billing from June 2026 — pricing model in transition - Code sent to Microsoft/GitHub servers — residual privacy concerns for sensitive enterprise codebases - Experience can feel fragmented across CLI, IDE extensions, Copilot Workspace, and the web interface ## Pricing ### Free $0/mo 2,000 completions, 50 premium req/mo ### Pro $10/mo Unlimited completions, agent mode ### Pro+ $39/mo Extended models, GitHub Spark ### Business $19/user/mo Team management, policy controls ### Enterprise $39/user/mo SSO, audit, IP indemnity, custom models GitHub Copilot is the most widely used AI coding tool, serving millions of developers across every major IDE. Originally launched as an autocomplete tool in 2021, it has grown into a full agentic platform with chat, agent mode, an autonomous coding agent, agentic code review, and natural-language app building via GitHub Spark. Inline completions remain context-aware across files, imports, and project conventions. Copilot Chat provides interactive AI assistance in-IDE and on GitHub.com. Agent mode — generally available on both VS Code and JetBrains since March 2026 — lets the agent edit multiple files, run commands, and iterate. The coding agent goes further: assign it a GitHub issue and it works asynchronously in a sandbox until a draft PR is ready. Multi-model access spans GPT-5.4, Claude Sonnet 4.6, Claude Opus 4.7, and Gemini 2.5 Pro. ## Key Features • Inline completions: real-time ghost-text suggestions in every major IDE • Copilot Chat: conversational assistance in-IDE and on GitHub.com • Agent mode: multi-step task execution (VS Code + JetBrains) • Coding agent: autonomous issue-to-PR worker that runs in a sandbox • Agentic code review: gathers project context, can hand off fixes to the coding agent • GitHub Spark: natural-language app builder (Pro+ and Enterprise) • Multi-model: GPT-5.4, Claude Sonnet 4.6 and Opus 4.7, Gemini 2.5 Pro, and more • Enterprise: SSO, policy controls, audit logs, IP indemnity, custom models ## Version History Copilot SDK + CLI GA (Feb–Apr 2026) Feb 25, 2026 Copilot CLI reached General Availability (Feb 2026) with terminal-native agent workflows, specialized sub-agents (Explore, Task, Plan, Code-review), parallel execution, and MCP support. GPT-5.4 rolled out across all surfaces (Mar 2026). Copilot SDK launched in public preview for embedding Copilot's agent runtime into custom applications (Apr 2026). Coding Agent GA (Sep 2025) Sep 25, 2025 Asynchronous coding agent promoted to General Availability for all paid subscribers. Agent takes GitHub issues, works autonomously in a secure cloud environment (GitHub Actions), and opens pull requests with the completed implementation. Agent Mode + Copilot Edits GA (Feb 2025) Feb 6, 2025 Agent mode launched in VS Code preview: multi-file edits, terminal command execution, self-healing error fixing, and next edit suggestions. Copilot Edits reached GA. Gemini 2.0 Flash and OpenAI o3-mini added as selectable models. Best for Everyday coding with the broadest IDE coverage, multi-model access, and increasingly autonomous agent features Capability Inline completions, Copilot Chat, agent mode (VS Code + JetBrains), autonomous coding agent, agentic code review, GitHub Spark Runs on VS Code, JetBrains IDEs, Visual Studio, Neovim, Xcode, GitHub.com, mobile Signature Snippet Copy ``` `Assign a GitHub issue to Copilot: it analyzes the repo, edits files on a branch, runs the test suite in a sandbox, and opens a draft PR with a written summary. Review, comment, and either merge or send it back for another pass.` ``` ## More in this Space SO ### Sourcery Closed source AI code review platform for the AI era.
