Cline vs Liner: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Cline and Liner — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Cline
Cline Bot Inc
Open-source coding agent runtime that runs in your IDE, your terminal or embedded via SDK, works with any model, and asks approval on every step.
Key features
- One runtime, three surfaces: The same agent runs as a VS Code extension, a terminal CLI, or embedded in your own product through the SDK
- Model agnostic: Works with Claude, GPT, Gemini, local Ollama or LM Studio models and any OpenAI-compatible endpoint, using your own key or weights
- Plan then Act: Align on a strategy in Plan mode before execution, then approve each step in Act mode or flip on auto-approve
- Multi-file edits with undo: Coordinated changes across a project with linter-aware fixes, diffs, checkpoints and one-click undo on every step
- Live terminal execution: Runs bash commands and reacts to output as it appears, handling dev servers, test runs and deploys
- Rules and Skills: Ship .clinerules with the repo so the agent follows your coding standards, architecture and deployment conventions
- Multi-agent teams: Coordinator agents delegate to specialists with their own tools and context, and can run on cron for recurring automation
- MCP and integrations: Register MCP servers and custom tools, chat from Slack, Discord, Telegram or Linear, and run headlessly in GitHub Actions or GitLab
Best for
- A developer onboarding to an unfamiliar codebase and asking the agent how files, dependencies and behaviour fit together
- Refactoring across a large repository while keeping imports, types and behaviour consistent
- Running recurring maintenance — dependency bumps, lint sweeps, scheduled checks — from cron or a CI pipeline
- A team that must keep code on self-hosted or local models for compliance reasons, pointing the agent at its own endpoint
- Embedding an agent loop inside an internal developer platform via the SDK instead of building one from scratch
- Encoding team conventions in .clinerules so every engineer's agent produces consistent, review-ready changes
- Triggering a coding task from Slack or Linear and having the agent open the resulting change
Liner
Liner
