Cline - 2026 Pricing, Features, Reviews & Alternatives

Cline is an open-source (Apache 2.0) AI coding agent that operates inside popular editors (VS Code, Cursor, Windsurf, and others) and terminals, supporting any LLM provider including OpenAI, Anthropic, Google Gemini, and local models. It handles multi-step development tasks autonomously: reading and writing files, executing CLI commands, controlling a browser, and managing the full software development lifecycle from planning through deployment. Model-agnostic by design, Cline connects to any API-compatible provider or custom endpoint, giving teams full control over cost, latency, and data residency.

Cline extends its core capabilities through a Model Context Protocol (MCP) server ecosystem, allowing teams to integrate external tools, internal APIs, and custom workflows directly into the agent's task execution pipeline. A built-in Plan/Act mode separates reasoning from execution, letting developers review proposed changes before they are applied. All file edits are presented as diffs with explicit approval steps, and a checkpoint system enables rollback to any prior state. These controls make the agent suitable for production codebases where auditability and reversibility are requirements.

Targeted at individual developers, engineering teams, and enterprises, Cline supports both interactive and automated usage patterns. It runs in agentic loops for long-horizon tasks and exposes a programmatic interface for CI/CD and scripted workflows. Deployment is local by default, with no vendor lock-in on model or infrastructure, making it a fit for organizations with strict data governance or air-gapped environments.
