Common questions

How long can I use Assertible for free?

Forever! You can use Assertible as long as you need, and if you need to test more web services or add more frequent health checks, check out the upgrade options above.

Are there any per-user fees?

No, there is only one monthly charge per account. Each plan has a limited number of members you can invite.

What if I need higher limits?

Check out one of the paid plans above! If you're a solo developer/tester, or a team with multiple people, we should have something that fits your need. If not reach out and let us know - we can get you set up.

Do you have request limits per month?

Instead of limiting the number of requests you can make, limits are placed on the number of results you can see for those requests, the number of tests you can create, how frequently you can run schedules, etc.

Can I try an upgrade before paying?

For all paid plans, we currently offer 1 free month so you can try out the premium web service testing features without hesitation. If you have any questions, reach out and we'll be happy to help get you set up.

Can I change plans or cancel at any time?

Yep. When you upgrade or downgrade your account, all charges are automatically pro-rated. That means if you need to, you can cancel any time.

What types of payments do you accept?

We currently support Visa, MasterCard, American Express and Discover cards. We do not accept PayPal or send P.O. invoices. Reach out any time if you need to use a method of payment we don't support.

Assertible helps identify and prevent user-facing bugs in APIs and web applications.
