FlareCost is a cost calculator for Workers, D1, R2, KV, Durable Objects and Queues. Adrian Pardo runs it. There is no postal address.
The estimate
Figures come from the published rate card on the date the page shows. They are not an invoice, a quote from the company that publishes that card, or financial advice. Rates change. On the Free plan, going over a cap can fail the request instead of creating a charge. R2 is the exception the calculator describes: past the free tier, it bills.
You use the calculator on your own judgment. There is no warranty that a figure is complete or free of error.
