“If I told an engineer they have to build all these libraries, they’d tell me it would take at least a year. With Stainless, it’s like magic.”
FAQ
Users can upgrade or downgrade between Stainless plans in the Billing settings any time. When you exceed the terms of our Free Plan, you will automatically be enrolled into a 30-day free trial of a paid plan.
When your trial period comes to an end, you will no longer have access to paid features and you will either need to subscribe to one of our paid plans or downgrade yourself to our free plan.
Stainless SDKs are counted based on whether they are published to your own Github organization. We do not charge for SDKs while you test and iterate on them internally within Stainless’ staging environment.
For customers on the Startup or Business plan, if the number of endpoints configured in your SDKs exceeds the limit set by the plan, you will be asked to confirm overage billing for the additional endpoints at a rate per live SDK/endpoint/month.
Stainless is billed upfront on a monthly or annual basis and can be paid with a credit card or linked bank account for ACH debit. The Stainless Business and Enterprise plans offer Purchase Orders/Invoicing with negotiable payment terms as an option. Additional sales taxes may apply depending on your business location.
The generated SDK code is owned by the customer and published by Stainless under the Apache 2.0 license. If you discontinue using Stainless, we will no longer publish OpenAPI and security updates to your SDKs, but you can continue using the existing code.
Yes! We proudly offer our startup plan for free to qualifying non-commercial open source (FOSS) projects. Just tell us about your project at opensource@stainlessapi.com after creating a free Stainless account and we can get you set up.
While the Stainless code generation cannot be hosted on-premise, Stainless only requires an OpenAPI spec to be shared, which typically does not contain sensitive information. The generated SDKs can be hosted in a private Github repository within your organization, until you are ready to share them with customers.
If you are on our Business or Enterprise plan, we can provide our SOC2 compliance report upon request. Please get in touch with sales@stainlessapi.com
We do require Stainless users to have a Github account for authentication and to gain access to the staging Github repositories we generate for customers. Anyone can set up a personal Github account in minutes and it does not need to be associated with a company organization.
