TNG is a smart test generation tool that turns your code into complete test suites โ€” 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, with more languages coming soon. This tool was born out of the real frustration of watching developers spend countless hours writing and maintaining repetitive tests, instead of solving problems and shipping features. Deadlines donโ€™t wait, and writing tests eats your time. We had to fix this.

Whatโ€™s new or unique: TNG is not a generic tool, but a static analysis engine that understands your code and turns it into complete test suites.

Cross-language roadmap: Ruby and Python now โ€” JavaScript, TypeScript, Go, and more coming.

Focused on real developer workflows: no overhead, no friction, easy to integrate.

Generates real tests in minutes, not hours, giving you back valuable development time.

Unlike old, rigid test generators, TNG adapts and grows with your stack.

What we're proud of: - We've built something that truly fits into a developerโ€™s daily workflow. - No fluff, just real value that saves time and increases productivity. - A bold roadmap: not just one language or ecosystem.

We are a small team with a big vision: focused on quality over quantity.

Questions & Answers

As answered by people managing tng.sh and Codeium.

What makes your product unique?

tng.sh's answer

Purpose-built, not generic

Unlike broad AI code assistants, TNG.sh is laser-focused on one thing: high-quality test generation.

No prompt engineering, no guesswork โ€” just predictable, framework-native tests.

AST-based static analysis + fine-tuned LLMs

Deep code understanding through AST (Abstract Syntax Tree) parsing.

Generates real, runnable tests with anti-hallucination rules โ€” not made-up methods.

Seamless developer workflow

Works where developers already are: CLI for automation & CI/CD, VS Code extension for day-to-day coding.

Minimal setup, instant value.

Cross-language roadmap

Ruby & Python today.

JavaScript, TypeScript, Go, and more coming next.

One tool, multi-language coverage.

Privacy-first

Zero data retention: your code never leaves your control.

Unlike chat tools, TNG.sh doesnโ€™t store, train on, or leak your IP.

Built by developers, for developers

Born out of real frustration with repetitive test writing.

Every feature solves problems weโ€™ve faced in production ourselves. In short: TNG.sh saves you hours, integrates seamlessly, and guarantees real, runnable tests โ€” with zero compromise on privacy.

Why should a person choose your product over its competitors?

tng.sh's answer

Built for tests, not everything

Competitors are broad AI assistants โ†’ unfocused, inconsistent.

tng.sh is purpose-built for one job: generating high-quality, runnable tests.

Real tests, not guesses

Competitors rely on prompts and often hallucinate methods.

tng.sh uses AST-based static analysis + fine-tuned LLMs โ†’ framework-native, predictable, CI-ready tests every time.

Saves time, every run

Competitors = back-and-forth, lots of manual fixes.

tng.sh = production-ready tests in 1โ€“2 minutes, with up to 22ร— faster output than manual writing.

Seamless developer workflow

Competitors force you into new tools or chat UIs.

tng.sh plugs in where you already are โ†’ CLI, VS Code, and CI/CD.

Privacy first

Competitors often store and train on your code.

tng.sh never stores or retains your code โ€” zero data retention by design.

Grows with your stack

Ruby & Python today.

JavaScript, TypeScript, Go, PHP coming soon โ†’ one tool, multi-language future. In short: tng.sh is faster, safer, and more consistent than generic AI tools โ€” because it was built by developers who know the pain of testing.

How would you describe the primary audience of your product?

tng.sh's answer

Software Developers & QA Engineers Developers who spend too much time writing and maintaining repetitive tests for Ruby, Python, and soon JavaScript projects.

Tech Leads & Engineering Managers Leaders who need higher test coverage, faster delivery, and more predictable quality without overloading their teams.

Startups & Growing Teams Small teams under pressure to ship features quickly, where developer time is the most valuable currency.

Enterprises Modernizing Legacy Code Companies with large, untested codebases that need reliable test coverage to move fast without breaking production.

What's the story behind your product?

tng.sh's answer

TNG.sh wasnโ€™t born in a boardroom โ€” it was born in the trenches of real software projects.

Our team had spent years writing and maintaining tests for Ruby on Rails and Python applications. Again and again, we saw the same pattern:

Deadlines always won.

Tests took hours or even days.

Legacy code felt like walking through a minefield with zero coverage.

Developers were frustrated. Managers were frustrated. Features slowed down.

We asked ourselves: What if generating tests could be as fast and natural as writing code itself?

That question became the seed for TNG.sh.

We built a precision tool that deeply understands your code with AST-based static analysis, then combines it with fine-tuned LLMs to generate production-ready tests in minutes, not hours.

Unlike generic AI assistants, TNG.sh is:

Purpose-built for tests โ†’ predictable, framework-native results.

Privacy-first โ†’ zero data retention, your code stays yours.

Seamless โ†’ works in CLI, VS Code, and CI/CD without overhead.

Itโ€™s more than just a tool โ€” itโ€™s a way to give developers back their most valuable resource: time.

In short: TNG.sh is the result of our own pain as developers โ€” a tool we wish weโ€™d had years ago, now built for every team that wants to ship faster, safer, and with confidence.

Which are the primary technologies used for building your product?

tng.sh's answer

TNG.sh combines modern programming languages and AI with proven developer tooling:

Core Engine: Built with high-performance systems programming (Rust, Python).

Code Intelligence: Advanced static code analysis with AST parsing for Ruby, Python, and JavaScript (in beta).

Test Generation: Fine-tuned machine learning models specialized for test creation and framework patterns.

Developer Interfaces: Simple, familiar tools โ€” CLI packages and a VS Code extension โ€” designed for seamless integration into daily workflows.

Privacy by Design: Cloud-backed but zero data retention โ€” code is never stored or reused.

In short: Static analysis + AI + developer-friendly interfaces.

Who are some of the biggest customers of your product?

tng.sh's answer

TNG launched in September 2025 and is currently in its early growth phase with 1,000+ developers actively using the platform.

Since many of our customers prefer to stay private during beta, we describe our user base like this:

By company size:

Seed to Series C startups (fintech, healthtech, SaaS)

Development agencies managing multiple client projects

Individual developers inside Fortune 500 companies

By use case:

Startups reaching 90%+ test coverage before Series A

Agencies cutting project delivery time by 40%

Enterprise teams modernizing legacy codebases

Results across all customers:

94% average test coverage

22ร— faster than manual test writing

50,000+ tests generated in the first month

We are committed to privacy-first relationships and will publish detailed case studies with customer permission in Q4 2025.
