Get pvSpline
pvSpline on the web runs the whole engine in your browser: nothing to install, no GPU needed. Start free, with no time limit, and subscribe when your needs grow.
Pricing
The subscription is pvSpline on the web, priced per seat and billed monthly. It renews automatically every month until you cancel it; a cancellation takes effect at the end of the month already paid. When a subscription ends, or while a renewal payment is failing, your company is on the free plan. The free plan uses the same engine, with identical results. Its work runs after paying customers’ work: when the servers are busy it waits, and a batch, an optimization, a tile build or a 3D session in progress may be paused or ended for theirs. On the free plan your company may admit any number of members, who share its allowances; on the subscription each member has their own. For professionals only. All prices ex-VAT.
Free
Every feature but Enedis data, on your own projects, within small monthly allowances.
No card, never charged

Suitable for 200 projects and 20 3D projects a month. This estimate depends on your workflow and data.
Subscribing needs a verified account: email confirmed and SIREN found active.
One seat per person in your company, and one per server or CI pipeline that connects to pvSpline. Choose how many seats at checkout and change the number from your Account page: a seat added mid-period is charged at once, pro rata; a seat removed comes off the next invoice, pro rata. The free plan has no seats: invite as many colleagues as you like.
Every allowance but file imports counts seconds of use: engine time for simulations, streamed time for 3D, build-runner time for tile builds and server time for cloud API requests. Allowances reset at the start of each calendar month. On the subscription, each member of the company has their own allowances, not shared with colleagues. On the free plan, the company has one set of allowances, shared by all its members however many they are. A light simulation uses about one engine-second; batch sweeps, optimizer runs and minute-level simulations use more.
