The service

RetryLab, by Ettix, provides a local test runner and a browser-based report viewer for checking how a webhook workflow you operate behaves when it receives duplicate, concurrent, out-of-order and retried synthetic events. You are responsible for the systems you test.

Use only on staging systems you control

The runner sends real HTTP requests to the URLs you configure. Point it only at staging or test systems that you own or are authorized to test, backed by empty or disposable test data. Do not point it at production. The events are synthetic, but they are real requests and create real records in the system you target.

Price and what you get

The free tier includes the demo, one sequential duplicate test and a basic text or JSON summary. A one-time payment of $39 USD unlocks, for one project ID only, the full five-scenario runner and shareable PDF and JSON reports. There is no subscription and no expiry. The unlock does not transfer to other project IDs. Payments are processed by Square or PayPal; the server unlocks a project only after the provider confirms an exact $39 USD payment.

Purchase record

Your unlock is a signed purchase record stored in your browser. Download and keep it to restore the unlock later. For new checkouts, the payment return link can also restore the unlock in another browser for 30 days after confirmation. We do not store your reports and cannot recover a lost purchase record without the payment details, which you can send to support.

No guarantee of results

RetryLab reports what your observer says happened during the test. It cannot prove the observer is correct, and a passing run does not show that production is safe. An incomplete result means evidence was missing and is not a pass. The service and software are provided “as is” without warranties, and Ettix is not liable for losses arising from use of results or from requests sent to your systems.

If a paid feature does not work for your project, contact support with your payment receipt.
