Cline

Open-source autonomous coding agent for VS Code

Cline is an Apache-2.0 open-source AI coding agent runtime for editor, terminal, and SDK workflows. It reads and edits files, runs commands, uses browsers, plans then acts, and requires explicit approval for each step unless users enable auto-approve. Current Cline sources show 8M+ installs, 63.6k+ GitHub stars, BYOK/provider flexibility, local model support, MCP, plugins, hooks, and Enterprise governance.

About Cline

Cline is an Apache-2.0 open-source AI coding agent runtime that works in editors, the terminal, and SDK-based integrations. It can read and edit files, execute terminal commands, use a browser, refactor large codebases, and automate recurring development workflows while keeping the developer in control through approval checkpoints. Current Cline sources show 8M+ installs across platforms and about 63.6k GitHub stars at write-prep time.

Cline's practical strength is control and portability. It supports Plan and Act workflows, checkpoints and undo, MCP servers, plugins, hooks, rules, skills, multi-agent teams, scheduling, and provider choice across Claude, GPT, Gemini, local Ollama or LM Studio, and OpenAI-compatible endpoints. That makes it a better fit for teams that want BYOK economics, local or client-side workflow ownership, and model/provider flexibility rather than a single managed agent platform.

Pricing is not a seat-fee subscription for individual open-source use. Cline is free for individual developers, and users pay only for model inference through Cline provider, BYOK cloud credentials, or local models. Enterprise is a custom plan for organizations that need centralized billing, team management, SSO/OIDC/SCIM, RBAC, audit logs, provider controls, SLA, OpenTelemetry, and dedicated support.

Pricing & Platform Specs

Pricing Summary

Cline is a free and open-source autonomous coding assistant extension (Apache 2.0) available at no cost ($0). It functions on a bring-your-own-key (BYOK) model where users pay token costs directly to their chosen AI model providers, with zero markup from the tool.

OpenCode vs Cline — Terminal Coding Agent or VS Code HITL Agent?

OpenCode and Cline both deliver open-source agentic coding help, but they live in different shells. OpenCode is an MIT coding agent spanning terminal, IDE extension, and desktop, with any-provider models and a polished coding-agent loop. Cline is an Apache-2.0 coding agent for editor, terminal, and SDK workflows that reads and edits files, runs commands, and asks for explicit approval unless you enable auto-approve. Existing Scores: OpenCode overall 83 (Score date 2026-09-05); Cline overall 84 (Score date 2026-03-25). Overall is close; choose on terminal coding-agent DX vs editor human-in-the-loop control. Treat the scoreboard as review evidence with those dates, not the whole decision.

Amp vs Cline — Terminal Code Intelligence or Open-Source VS Code Agent?

Amp and Cline both deliver agentic coding help, but they live in different shells. Amp is Sourcegraph’s commercial agentic coding tool with local threads, Orbs remote machines, and Dial modes. Cline is an Apache-2.0 VS Code coding agent that reads/edits files, runs commands, and asks for explicit approval unless auto-approve is on, on a BYOK model path. Use Amp when you want Orbs/Dial and Sourcegraph-line code intelligence. Use Cline when you want an open-source VS Code agent with human-in-the-loop control. Existing aicoolies Scores (both Score-dated 2026-03-25): Amp overall 85, speed 87, privacy 83, developer experience 84; Cline overall 84, speed 78, privacy 88, developer experience 86. Overall is nearly tied — choose on product shape, licensing, and current surfaces first; the scoreboard is secondary review evidence with those dates.

Codex vs Cline: OpenAI Coding Agent or Open-Source BYOK Agent Runtime?

Codex and Cline are both agentic coding tools, but they optimize for different buyers. Codex is the managed OpenAI coding agent across app, editor, terminal, SDK, and cloud workflows. Cline is the Apache-2.0 open-source agent runtime for teams that want BYOK economics, provider choice, local approval loops, and editor/terminal control. Choose Codex for the lowest-friction managed agent stack; choose Cline when open-source control and model portability matter more.
