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 donโt wait, and writing tests eats your time. We had to fix this.
Whatโs 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 developerโs 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.
Makerkit is a production-ready SaaS starter kit built with Next.js App Router and Supabase that helps developers launch faster.
It provides a robust foundation with built-in authentication, team management, billing integration, and Super Admin - all powered by a modular architecture that makes customization and maintenance a breeze.
Whether you're building a B2B or B2C application, Makerkit handles the complex infrastructure so you can focus on building your product's unique features using modern tools like TypeScript, React, and Tailwind CSS.
tng.sh
Makerkit.devtng.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.
Makerkit.dev's answer:
Indie Hackers and Companies who want to launch quickly, without compromising on quality.
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.
Makerkit.dev's answer:
Makerkit uses Next.js 15 (App Router), Supabase, React.js, Typescript and Stripe.
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 doesnโt 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 weโve faced in production ourselves. In short: TNG.sh saves you hours, integrates seamlessly, and guarantees real, runnable tests โ with zero compromise on privacy.
Makerkit.dev's answer:
Makerkit stands out by offering a truly modular architecture built with Turborepo, where core features like auth, billing, and notifications live in their own packages for better maintainability.
While most starters lock you into specific patterns or providers, Makerkit gives you flexibility with a multi-account system supporting both B2B and B2C scenarios, provider-agnostic billing, and edge-ready deployment options.
Beyond the basics, it includes production-ready features like multi-factor auth, real-time notifications, and team permissions - all built with Supabase, TypeScript, React Query, and modern tooling to make development a genuine pleasure.
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 1โ2 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.
Makerkit.dev's answer:
While other starters give you basic auth and a dashboard, Makerkit provides a genuinely modular foundation with the real features SaaS products need - like multi-factor auth, team permissions, real-time notifications, and provider-agnostic billing, all organized in clean, maintainable packages using Turborepo.
You get a first-class developer experience with TypeScript, React Query, and modern tooling, plus the flexibility to support both B2B and B2C scenarios, different payment providers, and edge deployment options.
Best of all, Makerkit is actively maintained with regular updates and responsive support, so you're building on a foundation that grows with your needs rather than painting yourself into a corner.
tng.sh's answer
TNG.sh wasnโt 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.
Itโs more than just a tool โ itโs 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 weโd had years ago, now built for every team that wants to ship faster, safer, and with confidence.
