Checkcraft in practice

A Postman alternative for API and log checks

If your workflow includes both API responses and logs, try a tool on that whole workflow. A product comparison is more useful when it ends with a task you can repeat.

How to repeat it Try Checkcraft

What you can verify

You can import a familiar request, add a field rule and inspect a log-based check before deciding whether Checkcraft fits your work.

The record is selected by traceId. Its embedded message JSON contains FAILED instead of PAID, while the amount check passes. Actual detailed Log run report with rules next to the checked values. Open the screenshot to see the full run screen.

Choose a concrete comparison

Take a small workflow such as sending a request, checking a total and finding a related log event. Compare the setup, editing and failure report for that workflow. Avoid treating a long feature list as proof that two products behave the same way.

Check migration limits

Checkcraft can import cURL, OpenAPI and Postman requests. Review imported variables and authentication. Existing test scripts, collaboration features and hosted services from another product may require a different approach or may not have an equivalent here.

Try the local example first

The sample below demonstrates an actual field check without a server connection. Then try your own sanitized request in a test environment. Free is available for Windows and Linux, with the current limits listed on the pricing page.

Repeat the check with ready-made files

The quick experiment below runs in the test case editor. The screenshots show the detailed report available in HTTP run or Log run. For HTTP run, return the sample JSON or XML from a local mock and run the imported case against it, then open Results, Details and With structures. For Log run, load the sample into a log source, enable No request, run the case, then open Details and Detailed.

Download the Checkcraft test case and two inputs. One input is valid, and the other contains a deliberate error. These synthetic examples are available without registration.

Importable test case JSON Valid data JSON Broken data JSON

Run the example in Checkcraft

Create a collection, a check and a test case using the workspace tree context menu. Click Import in the test case editor and choose the downloaded test case. Open the added case, copy the valid JSON, click Paste data for analysis, then Run test case. Open Result to inspect the report.

Repeat with the broken JSON without changing the rules. The first run should pass and the second should fail. If you see a different outcome, check the selected data source, imported steps and report.

The example files were executed against the application source on 14 September 2026. Reference reports in English are available for the passing run and failing run. Sample names and literal data values do not change when you switch the interface language.

Compare other tools against their own documentation, including Postman test examples and SmartBear ReadyAPI.

Compare API clients on one operation

When considering Postman, Bruno, Insomnia, Hoppscotch and Checkcraft, test a request, environment transfer and the way assertions are stored. A free tier is not an open-source license, and desktop software is not automatically air-gapped. Start with a deliberate failure and review the resulting report. This page describes Checkcraft rather than distributing other clients.

Try your own check

See the result on a small example first

Start with the sample, inspect the failure and then try a sanitized example from your own API. Free is available for Windows and Linux with no time limit.
