Core Features for API Testing
Natural Language API Testing
Write what you want tested. The agent breaks it into scenarios, hits the endpoints, and reports back. Test REST APIs without writing code.
Real API Requests
Tests run against your actual API. Real status codes, real errors. No mocks.
One-Command PDF
Export test results to PDF. Perfect for sharing with your team. Learn how.
Multiple LLM Provider Support
Use OpenAI, Claude, OpenRouter, or run models locally with Ollama and llama.cpp. Switch providers anytime without changing your tests. View all providers.
Perfect for Every Developer Workflow
Whether you're building APIs, automating tests, or validating OpenAPI specs, Octrafic fits seamlessly into your development process.
Test REST APIs Without Writing Code
Backend developers can test API endpoints during development using natural language. No need to write test scripts or maintain complex frameworks.
Automate API Testing in CI/CD Pipelines
DevOps teams can integrate Octrafic into GitHub Actions, GitLab CI, or Jenkins. Run automated API tests on every commit and catch regressions early.
Validate OpenAPI Specifications
Import your OpenAPI or Swagger spec and verify that your API behaves as documented. Octrafic automatically understands your endpoints and schemas.
API Testing for Non-Technical Teams
QA engineers without coding experience can test APIs using natural language commands. Describe what you want tested, and the AI handles the rest.
Lightweight Postman Alternative for CLI
Terminal-first developers get a lightweight alternative to GUI tools like Postman. Single binary, no runtime dependencies, works everywhere.
API Regression Testing Automation
Ensure API changes don't break existing functionality. Run regression tests automatically and export professional PDF reports for stakeholders.
Frequently Asked Questions About Octrafic
Is it really free?
Yes. Octrafic is open source and free to use with no limits. You bring your own LLM API key. View source code.
Which LLM providers are supported?
OpenAI, Anthropic, and any OpenAI-compatible API (Ollama, LM Studio, etc). Configure via environment variable or project settings. Configuration guide.
Does it work with any API?
Any HTTP API. You can point it at an OpenAPI spec or just give it a base URL and describe what to test.
How does natural language testing work?
Just describe what you want to test - for example "check if /users returns paginated results". The AI agent figures out what requests to make, runs them, and validates the responses.
What languages/platforms?
It's a single binary written in Go. Works on Linux, macOS, and Windows. No runtime dependencies. Installation instructions.
Why Choose Octrafic Over Other API Testing Tools?
vs Postman
Unlike Postman's GUI interface, Octrafic is a lightweight CLI tool that fits naturally into your terminal workflow. No electron app, no heavy UI. Just a single binary that works everywhere.
vs curl
While curl is powerful, it requires manual crafting of requests and validation. Octrafic uses AI to understand your API and automatically generates meaningful tests from natural language.
vs Test Frameworks
Traditional frameworks like Jest or Pytest require writing and maintaining test code. Octrafic lets you describe what to test in natural language. No boilerplate, no learning curve.
Stop writing test scripts. Start testing in plain English.
Open source CLI tool. Single binary. No telemetry. Works everywhere.
