Top 10 Bruno CLI Alternatives for Testing AI APIs

Apidog CLI is highlighted as the most interesting alternative to Bruno for testing AI APIs, offering terminal-based test execution and CI/CD integration. The article lists 10 tools including curl, HTTPie, Newman, Hurl, httpYac, and k6, noting that the best choice depends on specific workflow needs.

As I’ve been working more with Hugging Face inference APIs and model endpoints, I’ve been looking at alternatives to Bruno for API testing. Bruno is great for local API development, but different projects have different requirements. Here are 10 tools worth considering. This is the option I’ve been using most recently. Apidog CLI lets me run API test scenarios directly from the terminal and reuse them in CI/CD. I also like that it connects API testing with OpenAPI, documentation, and other parts of the API workflow. For AI APIs, this is useful when testing authentication, request payloads, response formats, and endpoint changes repeatedly. A good option for defining HTTP requests and expected responses in plain-text files. It can work well for automated API testing. A natural choice if you’re already working with Postman collections and want to execute them from the command line. Excellent for quickly exploring and debugging API endpoints from the terminal. Still one of the most universal options for making HTTP requests and testing endpoints. Useful for developers who prefer the Insomnia ecosystem but want to incorporate API workflows into automation. A lightweight option for defining and executing HTTP requests, particularly useful for developers who like file-based workflows. Useful for developers who prefer keeping HTTP requests alongside their source code and running them during development. Worth considering when API testing also involves performance and load testing. For highly specialized AI workflows, a simple Python script using requests or the Hugging Face client can sometimes be enough. There isn’t necessarily one winner. For quick requests, curl and HTTPie are hard to beat. For Postman collections, Newman remains useful. For file-based HTTP testing, Hurl and httpYac are interesting. For performance testing, k6 is a different but valuable option. For a broader API workflow that includes testing and automation, Apidog CLI has been the most interesting option for me. With Hugging Face APIs evolving quickly, being able to repeat the same API checks locally and in CI has become increasingly important. What Bruno alternative are you using for your AI API workflows?
