Cline

Editorial overview

Cline is an open-source coding agent available as a VS Code/Open VSX extension, CLI, and SDK. The catalog records its ability to edit files, run terminal commands and long-running processes, work through diffs with undo, and switch between Plan and Act modes. It can connect to hosted providers, local Ollama or LM Studio models, and OpenAI-compatible endpoints, so Cline is a runtime and workflow layer rather than a single model subscription.

That flexibility makes Cline attractive to developers who want to bring an existing model account, keep approval gates, or embed an agent in another tool. It also creates operational work: model credentials, context and token spend, permissions, MCP servers, and command approval are your responsibility. Treat autopilot and integrations as power features to introduce gradually. The official documentation should be the authority for supported providers, CLI/SDK behavior, and any current hosted features.

Pricing details

The catalog currently classifies Cline as free. Plans, included usage, model access, and account requirements can change. Confirm the current terms on the official product or pricing page before purchasing.

Getting started

1. Install the Cline extension from the supported VS Code or Open VSX route, or follow the official CLI installation guide.
2. Choose an approved provider and model, then authorize it using the documented credential flow; consider a local model for a controlled experiment.
3. Open a non-critical repository and inspect Cline's file, terminal, and approval settings before granting access.
4. Use Plan mode to ask for a task breakdown, review it, then execute a small Act-mode change with tests.
5. Add MCP servers, CLI automation, or SDK embedding only after recording permissions, costs, and rollback procedures.

Recommended workflow

Give Cline a bounded objective with acceptance criteria and the commands it may run. Plan mode is a useful checkpoint for identifying files, dependencies, and tests before edits. Ask it to explain uncertainty instead of allowing it to guess at architecture or credentials.

Review every proposed file change and terminal command. Cline's diff and undo workflow supports a tight loop: inspect, approve, run tests, inspect failures, and request a focused correction. Keep destructive commands, deployment, and secret access behind explicit approval even when using an autopilot setting.

Use provider choice deliberately. A capable hosted model may improve complex refactors; a local endpoint can reduce external sharing but may have different context, speed, or tool-use behavior. Track provider usage separately from Cline itself, and pin team configuration where reproducibility matters.

For automation, start with a read-only or disposable workspace. MCP servers, SDK calls, and chat integrations can connect the agent to systems outside the repository, so document scopes, rotate credentials, log outcomes, and require pull requests or equivalent review before merging.

Evaluation checklist

• Which provider, model, endpoint, and credential policy will the team standardize on?
• Are Plan/Act approvals, command restrictions, diffs, and undo sufficient for the repository risk?
• What token, latency, and model costs arise from typical tasks and retries?
• Can local execution, isolated workspaces, and MCP scopes satisfy data-handling requirements?
• Can the CLI, SDK, or integrations be upgraded and audited without breaking repeatability?
