Generate tests in minutes, not hours — get back your time

TNG is a smart test generation tool that turns your code into complete test suites — in minutes, not hours. Built by developers, to save your time, ensure code quality, and free you from repetitive test writing. Currently supports Ruby and Python.
Which are the primary technologies used for building your product?
TNG.sh combines modern programming languages and LLM with proven developer tooling:
Core Engine – Built with high-performance systems programming. We experimented with C, C++, and Go before settling on Rust for its speed, safety, and strong integration with both Ruby and Python ecosystems.
Code Intelligence – We use advanced static code analysis with AST parsing to extract and analyze only what's necessary. Currently supporting Ruby and Python, with JavaScript in beta.
Test Generation – Our fine-tuned, pre-trained LLM specializes in test creation and understands framework patterns, generating tests that actually make sense for your codebase.
Developer Interfaces – Simple, familiar tools you already know—CLI packages and a VS Code extension—designed for seamless integration into your daily workflow.
Privacy by Design – Cloud-backed but with zero data retention. We do not train on, sell, or keep your code. Only small bits of metadata and relevant code snippets are sent to generate tests—nothing is stored or reused.
In short: Static analysis + LLM + developer-friendly interfaces.
Hi devs 👋
As a team who struggled with endless hours of writing tests, we built TNG.sh to make that pain disappear.
If you’re a Rails developer, give it a try — it’s smart, fast, and respects your code.
You’ll be surprised how quickly it becomes part of your daily flow.
