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. It carries 66k GitHub stars under an Apache-2.0 license, and the vendor reports 8M+ developers across its surfaces. 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. Cline raised a $32M Series A alongside seed funding, and its homepage names developers and leaders at Samsung, Salesforce, Oracle, Amazon, LG, Globant, Microsoft, eBay, Visa, and IBM. 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 lets developers install community-built MCP servers, so Cline acts as an MCP client rather than publishing a server of its own. 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. ClinePass, launched June 2026, is an optional managed subscription for bundled open-weight models at $9.99 per month, currently promoted at $4.99 for a first month, giving reliable quotas on open-weight models without configuring provider keys. Cline notes that an additional processing fee may apply. 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. For bundled, predictable monthly billing, ClinePass covers open-weight models at $9.99 per month. Developers who want a fully managed IDE with bundled access to frontier proprietary models may prefer Cursor at $16/mo billed annually, which provides an IDE-native experience with no API key management required. GitHub Copilot at $10/mo covers the broadest IDE surface including JetBrains, Vim, and Visual Studio without configuration. Teams in regulated industries should note what Cline's trust center actually publishes: GDPR and SOC 2 are listed, but no SOC 2 report of either type is available and there is no ISO 27001 or HIPAA. Enterprise provides infrastructure isolation through VPC and air-gapped deployment rather than third-party audit certification. Current state Q3 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, and the SDK now dominates its release notes. Cline Kanban orchestrates parallel agents across tools in a single UI. The CLI 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, and Cline has announced a partnership with LG CNS for enterprise agentic AI development.
