Some years ago, I created an API testing tool, because most tools on the internet mainly focused on HTTP APIs, and I couldn't find a free and satisfying one that was covering all the types of APIs I worked with in my job, like relational databases, WebSphere MQ and IIB.

Overtime, I added more and more API types support and features to the tool, to satisfy my own new requirements. In the past year, I also rewrote the entire UI of the tool to catch up with the times.

API Test Base is an API testing tool that enables users to call HTTP APIs as well as many other types of APIs, manually or automatically. The tool has GUI, and enables no-code/low-code API testing.

The tool falls in the same category as Postman, but has some highlights:

    * Support many more API types than HTTP: relational database, JMS, MQTT, AMQP, IBM MQ, FTP, SFTP, IBM ACE. Even more API types can be supported in future.
    * Both standalone requests and plain old test cases are supported.
    * Use offline.
    * HTTP stubs.
    * Endpoints management.
    * Built-in data table (for data driven testing). Each cell can contain multi-line text (like JSON).
    * No code assertions. Placeholders in assertions.
    * Neat UI.
    * Theoretically faster UI and test cases execution because they run in separate processes (browser and JVM).
