Cline

Cline is the open-source autonomous coding agent built by Cline Bot Inc., available as a VS Code extension, a CLI tool, and as of May 2026, an embeddable SDK for building custom agents on the Cline runtime. With 63,600 GitHub stars under an Apache-2.0 license and over 8 million developer installs, Cline has become one of the most widely adopted open-source AI coding agents. The secure client-side architecture means all AI interactions happen directly between the extension and the chosen LLM provider: Cline itself does not process or intercept code or context in transit. Samsung Electronics confirmed adoption of Cline in its Device eXperience division for developer productivity in September 2025. Integration depth spans 12+ named LLM providers: Anthropic, OpenAI, Google Gemini, OpenRouter, AWS Bedrock, GCP Vertex AI, Azure OpenAI, Groq, Cerebras, Vercel AI Gateway, DeepSeek, and Ollama, with any OpenAI-compatible endpoint also supported. The CLI adds messaging platform integrations for remote agent management: Slack (including socket mode), Telegram, Discord, Google Chat, WhatsApp, and Linear. The MCP Marketplace extends the agent with community-built tool integrations, and Cline Kanban provides a UI for orchestrating parallel agents across Cline, Claude Code, and Codex simultaneously. Missing from the current integration set: no native Jira, Confluence, or project management tool connections beyond what MCP community servers provide. JetBrains IDE support is available only on the Enterprise tier. Pricing is fully public and straightforward. The open-source tier is free with no seat fees: developers pay only for LLM inference at provider rates through BYOK API keys or through Cline's managed inference at cost. Enterprise pricing is custom and adds JetBrains extension support, SSO with OIDC and SCIM provisioning, SLA guarantees, dedicated support, centralized billing, role-based access control, team management dashboard, authentication logs, VPC deployment, on-premises installation, and air-gapped environments. Fine-grained permissioning and advanced configuration management are listed as coming soon on the Enterprise tier. Cline is not the right fit for developers who want a managed subscription with bundled compute and predictable monthly billing. Cursor at $20/month provides an IDE-native experience with no API key management required. GitHub Copilot at $10/month covers the broadest IDE surface including JetBrains, Vim, and Visual Studio without configuration. Teams in regulated industries needing compliance certifications should note that Cline carries no SOC 2, HIPAA, ISO 27001, or similar certifications on any tier as of Q2 2026: Enterprise provides infrastructure isolation through VPC and air-gapped deployment but not third-party audit certifications. Current state Q2 2026: Cline launched the SDK in May 2026, rebuilding the entire extension on a new modular agent runtime that can be embedded into custom applications. The GitHub repository shows 63,600 stars, 6,700 forks, 6,174 commits, and 1,598 branches with active daily development. Cline Kanban orchestrates parallel agents across Cline, Claude Code, and Codex within a single UI. The CLI now supports messaging platform connections including Slack socket mode, Telegram, Discord, Google Chat, WhatsApp, and Linear for remote agent management. Enterprise capabilities have expanded to include OIDC, SCIM provisioning, and air-gapped deployment options.
