The short answer: Cline costs nothing for individual developers; what you pay is the model. Cline’s pricing page lists a free Open Source plan and a custom-priced Enterprise plan, with no seat fee on the Open Source plan (Enterprise is quoted by sales), and says you “only pay for AI inference credits when you use AI models”. Cline’s docs describe three ways to pay for those tokens: its own usage-billed provider, a flat $9.99 a month ClinePass, or your own API key. At Anthropic’s current API rates, on our stated assumptions, a heavy month on a mid-priced model costs about $120, six times a $20 editor subscription.
The three ways to pay for the model
From Cline’s docs and pricing page, checked 29 September 2026.
| Route | Cost | What the docs say |
|---|---|---|
| Cline provider | Usage billing | One sign-in, built-in billing, and free model options (the docs do not list which) |
| ClinePass | $9.99 a month | “2-5x the usage on popular open coding models compared to standard API rate” |
| Bring your own key | Whatever your provider charges | Cloud provider credentials or a local runtime |
| Enterprise | Custom, contact sales | Adds JetBrains extension, SSO/OIDC, role-based access and a team dashboard |
Two limits on what is published. ClinePass is described only for open coding models, so it does not cover Claude or GPT at a discount. And Cline does not publish what the “free model options” are or how much of them you get.
What a session costs on your own key
Anthropic’s API price list gives per-million-token rates. Take one agent step that reads 50,000 tokens of context and writes 5,000 (the same step used on our Claude Code pricing page), with no prompt caching:
| Model | Input / output per million | Per step | 40 steps a day, 20 days |
|---|---|---|---|
| Haiku 4.5 | $1 / $5 | $0.075 | $60 |
| Sonnet 5.5 | $2 / $10 | $0.15 | $120 |
| Opus 5.5 | $4 / $20 | $0.30 | $240 |
The step size and 40 steps a day are our assumptions, chosen to be easy to rescale; this is arithmetic on published prices, not a measurement of Cline. Cached reads bill at a tenth of the input rate on Haiku and Sonnet (5 percent on Opus 5.5), so long sessions that reuse context come out lower. Multiply the last column by your own step count.
Cline versus a subscription
The point of a subscription is a ceiling. With your own key there is none, only the controls you set with your provider. The $120 Sonnet row is more than Cursor Pro at $20 or Claude Pro at $20, but those plans cap the work you get. Anthropic’s cost guide puts the average at about $13 per developer per active day for Claude Code, while our assumed day costs $6 on Sonnet and $12 on Opus, so the arithmetic sits in the same range as the vendor’s own figure.
Rough guide:
- A few hours a week: your own key on a mid-priced model is likely cheaper than any subscription.
- Full-time daily use: compare the monthly total with a $100 or $200 plan on the Claude Code pricing page and with Cursor pricing before committing.
- Predictable bill needed: use a provider spend limit, or pick a flat plan.
More on how Cline works, and what it trades for the price, is in the Cline review; other options are in Cursor alternatives and the best free AI coding tools.
Method
Researched from Cline’s pricing page and documentation and Anthropic’s API pricing page on 29 September 2026. We have not run Cline for this page and measured nothing; the cost table is arithmetic on published rates, with assumptions stated. Re-checked every 30 days.
Common questions
Is Cline free?
The extension is free for individual developers. You pay the model provider for tokens, unless you use a free model or a local one.
What is ClinePass?
A flat $9.99 a month subscription that Cline’s docs say gives 2 to 5 times the usage on popular open coding models compared with standard API rates.
Does Cline charge per seat?
Not on the Open Source plan. Enterprise pricing is custom; Cline does not publish a per-seat figure.
