Common questions

Do I need to know how to code?

No. You describe what you want in plain language, and Spark creates the apps and pages you need, with accounts, data, and payments built in. When you want changes, ask for them the same way.

What does it cost to start?

You can start for free without a credit card. The Free plan includes one-time credits so you can try building with Spark. Publishing is free too, on a spark.site address. Taking payments and using your own domain need a paid plan, from $25 a month — see pricing.

Can I take payments?

Yes, on a paid plan. Tell Spark what you want to sell and how much to charge.
