Conektto is awesome!
I used both Design and Test Studios, and really appreciated the low/no-code platform's features to design API artifacts (spec; code; mocks; test data, cases, suites) through its drag-and-drop interface, without needing to resort to legacy, code-first JSON/YAML.
It's clear a focus on collaboration and hyper-automation are central to Conekkto's value proposition. The design/build/test features are elegant and intuitive, and the speed/cost efficiencies are second-to-none (connectors: SQL Server, Postgres, MongoDB, MySQL).
Also noteworthy is the one-click API lifecycle artifact generation from unified OpenAPI specification source which greatly accelerate automation, solving the unmet need and pain point of slow, siloed processes, needless API expense, and development friction.
The free Community tier has unlimited design to test drive the product, and the Pro plan expands unlimited access to several more features. Highly recommend Conekkto!
