Introduction
Cline is an open source coding agent. It runs as a VS Code extension, a CLI, a desktop app for macOS and Windows, or a JetBrains plugin. Its main difference from bundled tools like Cursor and GitHub Copilot is the billing model. Cline doesn't charge for the agent. You plug in a model provider such as Anthropic, OpenAI, Google, a local Ollama or LM Studio server, or any OpenAI-compatible endpoint, and you pay for inference. You can pay at cost through Cline or with your own key.
The project uses the Apache-2.0 licence. Its GitHub repository shows about 69.6k stars, 7,552 forks and more than 250 contributors, with recent pushes. That is heavy adoption for a developer tool. The same repository also shows 1,489 open issues, which is a large backlog. This review covers what Cline's own pages and repository say about features, pricing and limits. scored.tools did not test it hands-on.

Key Features
Four ways to run it
Cline ships as a VS Code extension, a CLI, a desktop app (macOS and Windows) and a JetBrains plugin. The CLI makes it usable in terminal-first setups and scripts. One point needs checking. The pricing page lists the "JetBrains Extension" only under the Enterprise column, but the main site presents a JetBrains plugin as one of the ways to run Cline. If your team works in IntelliJ or PyCharm, confirm with Cline whether you need an Enterprise contract before you plan around it.
Bring your own model
Cline works with Claude, GPT, Gemini, Ollama, LM Studio and any OpenAI-compatible endpoint. This is the main reason to pick it. You can send hard refactors to a frontier model, routine edits to a cheaper one, and private code to a model on your own hardware. If one provider raises prices or drops a model, you switch providers and keep the same agent and workflow.
MCP, an SDK and hooks
Cline supports the Model Context Protocol and has an MCP Marketplace, so you can connect tools like databases, issue trackers and internal APIs to the agent. It also has an SDK for custom tools and lifecycle hooks that run at set points in a task. This is the highest-scoring area in the tool data (9/10). Teams that want the agent to follow house rules or call internal services get real extension points here.
Multi-agent teams and scheduling
Cline lists multi-agent teams and scheduling, so it can coordinate several agents on a task and run jobs on a timer. Usage-based billing matters most here. More agents running more often means more tokens on your bill.
Client-side architecture and multi-root workspaces
Per the pricing page, Cline uses a "Secure Client-Side Architecture". The agent runs on your machine and talks straight to the provider you chose. Pair that with a local model and your code never leaves your network. Multi-root workspaces let one session span several repositories, which helps in monorepo-adjacent setups and service-per-repo codebases.
Pricing Breakdown
| Plan | Price | What you get |
|---|---|---|
| Open Source | Free | VS Code extension and CLI, MCP Marketplace, multi-root workspaces, inference at cost or with your own key, community support |
| ClinePass | $9.99/month | Flat subscription to a set of open-weight models, with 2-5x the usage of standard API rate limits, per Cline |
| Enterprise | Custom | JetBrains extension, SSO, SLA, role-based access control, centralized billing, provider limits, team dashboard, authentication logs, dedicated support |
Open Source: free, but the meter runs
The agent costs nothing. Your spend is whatever your model provider charges for the tokens Cline uses, and the free path has no cap. Agentic coding uses a lot of tokens because the agent reads files, plans, edits and re-reads in loops. A busy day on a frontier model can cost more than a month of a flat-rate tool. Set spending limits in your provider's console before you hand the agent a large task. The alternative is a free local model, which costs only hardware and electricity.
ClinePass: flat rate for open-weight models
The tool data describes ClinePass as "2-5x usage on popular models". The ClinePass page is more specific. It covers open-weight models from Z.ai (GLM 5.3, GLM 5.3 Flash, GLM 5.2), Moonshot AI (Kimi K3, Kimi K2.7 Code, Kimi K2.6), DeepSeek (V4 Pro, V4 Flash), MiniMax (M3), MiMo (V2.5 Pro, V2.5) and Qwen (Qwen3.7-Max, Qwen3.7-Plus, Qwen3.8-Max). Claude, GPT and Gemini are not on that list. Cline says $9.99/month is the standard rate after a promotional period, that extra processing fees may apply, and that quotas give 2-5x the usage of standard API rate limits. It gives no numeric caps. You can cancel before renewal and keep access until the term ends, and Cline says the ClinePass key also works with other coding agents. For $9.99 it's an inexpensive way to get predictable costs, as long as open-weight models are good enough for your work.
Enterprise: governance features, custom price
Enterprise adds the controls a security team will ask for: SSO, RBAC, centralized billing, the option to limit which inference providers developers can use, a team management dashboard and authentication logs. The FAQ also mentions OIDC, SCIM provisioning, audit logs, VPC deployments and OpenTelemetry. Advanced config management and fine-grained permissions are marked "Coming Soon". The pricing page lists no Teams tier, so a small team has two options. Each developer can run the free tier with shared or separate keys, or the team can go to a sales call.
Pros & Cons
Pros
- Apache-2.0 licence, about 69.6k GitHub stars and 250+ contributors. You can read, fork and audit the code.
- No subscription required. You pay only for the inference you use.
- Wide model support, including local models, which keeps you free of vendor lock-in.
- MCP, an SDK and lifecycle hooks give you real ways to extend and control the agent.
- Runs in VS Code, the terminal, a desktop app or JetBrains.
Cons
- Inference costs change with usage and have no cap on the free path. Budgeting is your job.
- 1,489 open GitHub issues suggests a sizable backlog.
- The pricing page lists the JetBrains extension under Enterprise, even though the site presents a JetBrains plugin as a general option.
- The free tier has only community support, and no mid-tier team plan is published.
- ClinePass covers open-weight models only, so a flat rate doesn't extend to Claude or GPT.
Who Is It For
Cline fits a developer who wants to pick the model, see the token costs and keep the option to switch. If you already have API keys, run models locally, or need code to stay on your own hardware, Cline gives you a full agent at no cost. Platform teams that want to connect agents to internal tooling get the most from the MCP support, the SDK and the hooks.
It's a weaker fit for a developer who wants one predictable bill that includes frontier models. Cursor and GitHub Copilot bundle inference into a subscription, and Codeium has a similar plan. Those cap your exposure in a way Cline's free path doesn't. Small teams that want admin controls without an enterprise contract will also notice the missing middle tier.
Verdict
Cline scores 8.2 out of 10. It's the strongest choice here for developers who want an open source agent and want to choose and pay for their own models. The licence, the adoption and the extension points (MCP, SDK, hooks, any OpenAI-compatible endpoint) all back that up, and API and integration scores highest at 9. Usage cost is the trade-off. The free path is uncapped, ClinePass makes costs predictable only for open-weight models, and the JetBrains and team-plan details need a conversation with Cline.
Recommendation: install the free VS Code extension or CLI, connect it to a provider with a hard monthly spend limit, and track a week of real usage. If the bill is within your budget, you have a flexible agent with no lock-in. If you want a fixed monthly price that covers frontier models, a bundled subscription tool will suit you better.
