What is Cline?
Cline is an open-source VSCode extension that turns your editor into an autonomous coding agent. It plans tasks, edits multiple files, runs terminal commands with your approval, and works with any model you bring (Claude, GPT, Gemini, local models).
What is GitHub Copilot?
GitHub Copilot is an AI coding assistant from GitHub and OpenAI/Microsoft, integrated into VSCode, JetBrains, Visual Studio, Neovim, and the GitHub web UI. It provides inline completions, chat, and (in agent-enabled tiers) multi-file edits.
When to choose Cline
Best for: Developers who want an autonomous agent inside their existing editor with full source-code audit, model freedom, and version-controlled coding governance via .clinerules.
Pros
- Open source under Apache 2.0 with 61k+ stars and 5M+ installs — full source audit, no proprietary state
- Plan/Act structure with explicit per-step human approval keeps the agent steerable on long tasks
- 30+ provider support (Anthropic, OpenAI, Google, Mistral, DeepSeek, Bedrock, Vertex, Ollama, plus the Cline Provider) — never locked to one vendor
- MCP Marketplace plus stdio/SSE makes plugging in Linear, Postgres, GitHub, and internal tools a one-click install
- Computer Use lets the agent verify its own UI changes by driving a real browser — closes the test-loop gap most agents leave open
- Runs across VS Code, JetBrains, Cursor, Windsurf, Zed, Neovim, and a preview CLI — not locked to a single editor in 2026
When to choose GitHub Copilot
Best for: Enterprise teams, GitHub-native shops, JetBrains and Visual Studio users who want a single SSO-backed AI assistant across all their IDEs, and any org where procurement friction is the deciding factor.
Pros
- Cheapest paid tier in the category at $10/month for Copilot Pro
- Agent mode is GA on both VS Code and JetBrains as of March 2026 — JetBrains parity is the unlock for Java, Kotlin, and Python shops
- Coding Agent: assign a GitHub issue to Copilot and get a fix PR back, fully autonomous
- Agentic code review now reads the whole project before suggesting changes; review comments can be turned into fix PRs in one click
- GitHub-native everything — billing, SSO, audit logs, policy controls already plugged into the org you've been on for a decade
