Blave Desktop is free. You pay only for the AI, data and cloud machine you use.
Blave Desktop is free. Blave Agent is a plan (monthly or yearly, Blave data in every tier, plus a cloud server if you want one); Blave AI runs on a prepaid balance, deducted by usage. Prices are shown in USD; payments are processed in TWD, so a few fixed amounts below are given in TWD. For Data Studio's Pro / API subscription plans, see the plans page.
| Item | How It's Charged | When You'd Use It |
|---|---|---|
| Blave Desktop | Free, open source | Download it and go |
| Blave Data | Cloud server and desktop app: included with a Blave Agent plan or the API plan; desktop only, open one of them (included during the card trial). Your own code with an API key: API plan required | When the agent uses Blave's indicators, positioning data or Taiwan stock data |
| Cloud machine | A plan, monthly or yearly; each period comes out of your balance first, or the card if it falls short, data included | When you want strategies running around the clock without keeping your computer on |
| Blave AI | Per token, from your balance | When you pick Blave AI in Blave Desktop. With your own Claude Code or Codex, Blave charges no AI fee |
Put your strategies in the cloud and they keep running around the clock, even with your computer off. It's a plan: monthly, billed every 30 days, or yearly (pay for 10 months, use 365 days), with Blave data in every tier. Linux Starter is the default; if you need more cores you can upgrade, effective right away, paying the difference for the days left in the period.
| Tier | Spec | Price |
|---|---|---|
| Linux (default) | ||
| Starter | 2 vCPU · 4 GB | 48 USD/mo 480 USD/yr |
| Premium | 4 vCPU · 16 GB | 144 USD/mo 1,440 USD/yr |
| Max | 8 vCPU · 32 GB | 276 USD/mo 2,760 USD/yr |
| Windows — required by Windows-only broker APIs (e.g. Capital Futures 群益) | ||
| Starter | 2 vCPU · 8 GB | 132 USD/mo 1,320 USD/yr |
| Premium | 4 vCPU · 16 GB | 204 USD/mo 2,040 USD/yr |
| Max | 8 vCPU · 32 GB | 396 USD/mo 3,960 USD/yr |
Each period comes out of your balance first; if it doesn't cover a full period, the whole period goes on your card. If it can't be paid, the server stops when the period ends and the charge is retried daily; after 7 days the server is deleted (with its strategies and data). Cancelling: the plan runs to the end of the period, no refund. Cloud servers can't be downgraded for now; to switch to a cheaper plan, wait until the current period ends. Terminating the server does not cancel the plan; it keeps being charged each period. Without a server, a failed charge only pauses Blave data, and the plan ends if it isn't paid within 7 days.
When you choose Blave AI on Blave Desktop or a cloud machine, usage is deducted from your balance per token; DeepSeek V4 Pro is the default. Your own Claude Code or Codex doesn't go through Blave and isn't charged here.
