Is Cline Free? What You Actually Pay to Run It

The extension is completely free and open source under the Apache 2.0 licence, for both VS Code and JetBrains. Cline charges nothing for the tool itself and takes no markup: you either bring your own API key and pay the model provider directly, or buy inference through Cline at cost. The only real cost is the model usage your tasks consume.

It depends entirely on which model you run. With a budget model such as DeepSeek or Gemini Flash, light daily use can come in around $1 to $5 a month. A typical developer mixing models usually lands between $10 and $30. Heavy agent use on frontier models — long autonomous sessions across large files — can reach $50 to $300 a month, which is the same Trap that makes people think Cline is expensive rather than the model.

No. Cline's stated policy is that inference bought through the extension is passed through at cost, with no markup, and BYOK is billed by your provider at their published rates. That is the structural difference between Cline and credit-based tools: you are paying for tokens, not for the vendor's margin on top of them.

Teams is $20 per user per month, and the first 10 seats are free forever — which makes it genuinely usable for small teams at no cost. The paid tier adds centralised management for larger organisations, and Enterprise is custom-priced. For most individual developers the free open-source extension is the whole product.

Because agents re-send context. Every planning step, file read and follow-up message carries the accumulated conversation, so a long thread on an expensive model compounds quickly. Large context windows, whole-file reads and vague tasks that make Cline explore are the three usual drivers of an unexpectedly large bill.

Four levers: route routine work to a budget model and reserve frontier models for hard problems; keep tasks tightly scoped so the agent does not explore; start fresh conversations per task instead of extending long threads; and watch the per-task cost readout Cline shows while it works so you can stop early when a run drifts.

Cline is bring-your-own-model agentic coding inside your existing editor, with a human approval step for every action, rather than a subscription that bundles usage. It costs more per token of effort if you run frontier models, but there is no seat fee, no credit markup, no unpublished usage pool and no vendor lock-in. If you want predictable flat pricing, Copilot or Cursor; if you want control and auditability, Cline.

Thirty-plus providers, including Anthropic, OpenAI, Google, DeepSeek, OpenRouter and any OpenAI-compatible endpoint — plus local models through Ollama or LM Studio. That range is what makes the cost range so wide: the same agent can run at a dollar a month or several hundred depending on what you point it at.

It can work through multi-step tasks — create and edit files, run terminal commands, read the results and iterate — but with a human-in-the-loop approval step rather than fully unattended execution. You can loosen or tighten how much it does without asking, and that setting is one of the main cost controls.

There is no trial because there is nothing to trial: the extension is free to install and use forever. The only cost you incur is model usage, which you can start at a few dollars a month with a budget model and scale up only if you need frontier quality.

Cost variability on frontier models, no bundled usage so you must manage keys and budgets yourself, a learning curve around context management, and heavier token consumption than autocomplete-first tools because it reads real files and reasons over them. It is also IDE-bound: VS Code and JetBrains rather than a standalone editor.

Developers who want agentic coding with full model control and no subscription, teams that need to keep model traffic inside their own provider agreements, and anyone running local models for privacy. It is also a strong fit for teams that already pay for model access through their own cloud agreements.
