Does pricing depend only on CDN usage?

No. Every Sonenta plan combines two limits: a number of included translation keys AND a CDN bandwidth quota. For example, Free includes 500 keys and 5 GB of CDN; Pro includes 50 000 keys and 250 GB.

How many translation keys are included per plan?

Free: 500 keys. Hobby: 5 000 keys. Pro: 50 000 keys. Team: 250 000 keys. One key is a single content string managed and delivered by Sonenta.

What is the CDN quota?

It's the bandwidth included to deliver your translations from the global CDN: Free 5 GB, Hobby 50 GB, Pro 250 GB, Team 1 TB. Beyond that, overage is billed at $0.20/GB with no plan change.

What happens if I reach the key limit?

You move up to the next plan, which includes more keys: the key count and the CDN quota grow together at each tier (from 500 keys on Free up to 250 000 keys on Team).

Honest pricing, no traps.

No per-word billing. No language surcharge. You pay for the size of your project, not the weight of your dictionary.

Included quotas & overages

Every plan includes bandwidth and storage. Beyond that: $0.20/GB, for both bandwidth and storage, billed as you go, with no plan change required, and your bandwidth is never cut off.

Variants (per-screen or per-region overrides) count toward your plan's string limit; a pluralized string counts once.

Taxes handled for you — Sonenta sells through Stripe as Merchant of Record: any applicable VAT, GST or sales tax is calculated and shown at checkout, included where local rules require it, then collected and remitted for you. No surprise tax.

Clear pricing

Two axes: included keys + CDN

Sonenta's price is based on two limits per plan — the number of included translation keys and the CDN bandwidth quota. Both scale together, tier by tier.
