Cline

Cline is the open-source autonomous coding agent built by Cline Bot Inc., available as a VS Code extension, a CLI tool, an embeddable SDK for building custom agents on the Cline runtime, a desktop app in beta since September 2026, and browser-based Cloud Agents that work in a sandbox and hand back a branch or pull request. It carries 71.5k GitHub stars under an Apache-2.0 license, and the vendor reports 11M+ 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 $32M in combined Series A and seed funding in July 2025, and its homepage names developers and leaders at Samsung, Salesforce, Oracle, Amazon, LG, Globant, Microsoft, eBay, Visa, and IBM.

Integration depth spans more than 40 documented model providers, from Anthropic, OpenAI, Google Gemini, OpenRouter, AWS Bedrock and GCP Vertex AI to Groq, Cerebras, Mistral, xAI and DeepSeek, plus local models through Ollama and LM Studio, 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. The JetBrains extension is Enterprise-only, but the CLI speaks ACP, so Cline can run as the agent inside Zed, JetBrains IDEs, Neovim and Emacs on any 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, 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 $8/mo, 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 Q4 2026: Cline shipped a desktop app in beta on September 14, 2026 (macOS, Windows and Linux), built for open-weight models with parallel sessions and scheduled tasks, and Cloud Agents that run tasks on a GitHub repository from the browser, up to 10 at once, on free models, ClinePass or credits. The SDK launched in May 2026 on a modular agent runtime that can be embedded into custom applications. 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.
