Your wallet is your budget
Fund a USD wallet and that balance becomes your spend cap. Design as many candidates as you want, pay only for the compute delivered. No credits, no tiers, no subscriptions. New accounts start with a $5 wallet balance.
A wallet, not a subscription
The model is the one you already use on Modal, OpenAI, and Anthropic. You hold a USD balance, jobs debit it at the actual cost of the compute they used, and you top up when it runs low. The whole pricing surface is one number, your balance.
1. Sign up free
Create an account at tools.ranomics.com. Get $5 in your wallet immediately, enough to try any tool on your own inputs before you top up.
2. Fund your wallet
Top up in any amount from $20. That balance is your cap. Your wallet is prepaid, so you can only ever spend what you have funded. Tax is added at checkout where applicable.
3. Design without limits
Request as many designs as you want. Large requests fan out into a campaign across GPUs and bill only for compute delivered. Every form shows the live estimate and your balance before you submit.
4. Auto reload, optional
Save a card to auto reload when balance drops below a threshold. Default off. Limited to one auto reload per 24 hours plus a monthly cap you set, so a runaway loop cannot drain your card.
The only limit is the balance you fund
There is no cap on how many designs you can run and no per design charge to budget around. Fund what you are comfortable spending, launch a campaign of any size, and it drains your wallet as the compute is delivered. If the balance runs out, the campaign pauses and picks up again the moment you top up. Everything already produced stays downloadable.
Every job and campaign displays a live estimate and your balance before you submit. You confirm or cancel. If a job ends up cheaper than estimated, the surplus returns to your wallet.
No surprise bills
Your funded balance is the ceiling. These guardrails make sure that ceiling is never crossed while you are asleep.
Prepaid, never a surprise
Your wallet is prepaid, so you can only ever spend what you have funded. A campaign pauses the moment your balance cannot cover the next unit of compute. Top up to continue, or download what has already finished.
Pay for compute delivered
Every job places a wallet hold against a live estimate, then settles at the actual compute consumed. Whatever the job did not use returns to your wallet. Failed sub jobs in a campaign are refunded.
Auto reload limits
Auto reload, when enabled, is limited to one charge every 24 hours plus a user set monthly cap (default $1,000). A compromised account or runaway loop cannot drain your card.
Mid run safety
Long running jobs report progress every 15 minutes. If the actual cost runs well past the estimate, you get a warning email so a bad input never runs away quietly.
Failed jobs
Infrastructure failures on our side refund the full hold. Jobs that completed normally but produced zero passing designs, or jobs you cancelled mid run, are billed for the GPU consumed. Ambiguous cases default to refund.
No refunds on top ups
Top ups are final. Unused balance does not expire. Start with a small top up to evaluate the platform if you are unsure.
Prefer a managed campaign with wet lab validation?
Self serve here is unlimited. If you would rather hand off the whole campaign, a Binder Pilot is the managed option: a fixed scope engagement with a defined deliverable, wet lab handoff if you want it, and a single point of contact. It is a different product, not a spend threshold.
