Cline
Cline is an open-source coding agent that runs in your editor, terminal, and pipelines. It plans tasks, edits code across repositories, executes bash commands, and integrates SDK tools and MCP servers while remaining model-agnostic and deployable on your own infrastructure.
Overview
Developers install the CLI once, add the VS Code extension, and select a model provider. Cline proposes a plan, then performs stepwise edits while showing diffs, running linters, and executing bash commands. Long-running servers, tests, and deploys stream live output for review or auto-approval.
Core Capabilities
Cline suits teams managing large or fast-changing codebases: platform engineering groups, Staff+ engineers, maintainers, DevOps and SREs, and founders building with small teams. It’s effective for cross-repo refactors, dependency upgrades, framework migrations, monorepo hygiene, backports, onboarding, and recurring checks where plans, approvals, and auditability matter.
- Applies consistent, linter-aware multi-file edits with diffs, checkpoints, and instant undo.
- Executes bash commands interactively and adapts to streaming terminal output in real time.
- Enforces project conventions using .clinerules to encode architecture, testing, and deployment guidelines.
- Works with Claude, GPT, Gemini, or local Ollama and LM Studio engines.
- Extends via SDK hooks and MCP servers to reach databases, APIs, and infrastructure.
Why It Stands Out
Architecture & Operations
Install the CLI with npm i -g cline on macOS, Windows, or Linux. Add the VS Code extension from the Marketplace or Open VSX. Connect provider keys or local models (Ollama, LM Studio), then author a .clinerules file to encode conventions. Start in Plan mode, review steps, and switch to Act. Optionally connect Slack or Linear for chat, and run headlessly from GitHub Actions or GitLab CI. Explore the SDK and MCP integrations to register tools and automate recurring jobs.
One agent runtime that plans, edits, and executes across editor, terminal, and CI.
Getting Started
Cline’s differentiator is a single, auditable runtime that spans editor, terminal, and CI with plan-first execution and one-click undo. It embraces any model provider and local engines, extends cleanly via SDK and MCP, and encodes standards in .clinerules. With millions of installs and active contributors, it’s a production-ready path to practical AI-assisted engineering.

Cline
Cline Bot Inc. stewards the open-source Cline agent alongside a growing community of 250+ contributors. The company focuses on pragmatic developer tooling, model-agnostic agents, and secure enterprise workflows, maintaining the VS Code extension, CLI, SDK, and MCP integrations across major AI providers.
Cline is a unified, Apache-2.0 open-source agent runtime for software engineering. It operates consistently across IDE (VS Code), CLI, and an embeddable SDK, so teams can move from prompt to production with the same workflows. The agent plans first, then acts, applying coordinated, linter-aware multi-file edits with diffs, checkpoints, and one-click undo. It executes bash in your terminal, observing output in real time to run servers, tests, and deployments. Rules are codified in .clinerules to align decisions with your architecture, conventions, and release process. Cline is model-agnostic: use Claude, GPT, Gemini, or local engines via Ollama or LM Studio, or any OpenAI-compatible endpoint, bringing your own keys or weights. Extend behavior through the SDK, lifecycle hooks, and Model Context Protocol (MCP) servers to reach databases, APIs, and infrastructure. Run it headlessly in CI, or chat from Slack, Discord, Telegram, or Linear. The result is a practical, auditable coding teammate that fits existing tooling and governance.
