Building with Transformers.js: Our Tech Stack Explained
At TokenCalculator.com, we've built a robust platform that provides accurate token counting and cost estimation for various language models. Here's a look at the technology stack that powers our service.
Frontend Technologies
Our frontend is built with modern web technologies to provide a fast, responsive user experience:
- HTML5/CSS3: The foundation of our web interface
- Tailwind CSS: For efficient, utility-first styling and responsive design
- Vanilla JavaScript: For interactive elements and DOM manipulation
- Transformers.js: The key to our client-side token counting functionality
The Power of Transformers.js
Transformers.js is a browser-compatible version of Hugging Face's popular Transformers library. It allows us to run tokenization directly in the browser, which offers several advantages:
- Privacy: Your text never leaves your browser for token counting
- Speed: No round-trip to our servers for basic token counting
- Offline Support: Basic functionality works even without an internet connection
We use Transformers.js to load various tokenizer models, allowing us to accurately count tokens for different LLMs using their specific tokenization algorithms.
Backend Technologies
Our backend is built with:
- PHP: Powers our MVC architecture
- Custom MVC Framework: Lightweight framework designed specifically for our needs
- JSON Data Storage: For model specifications and pricing data
Performance Optimizations
To ensure a fast experience, we've implemented several optimizations:
- Lazy loading of tokenizer models
- Client-side caching of model data
- Responsive design for all device sizes
- Dark mode support to reduce eye strain
The Team Behind TokenCalculator
Our team consists of AI engineers, web developers, and content creators who are passionate about making LLMs more accessible and easier to work with. We regularly use these models in our work and wanted to create a tool that would make it easier to optimize costs and improve efficiency.
We're connected to a broader ecosystem of AI tools, including some that share our commitment to making advanced AI more accessible:
- AnyWordCount.com for general text analysis
- AnyImg.com for image processing tools
- ZipToolkit.com for file compression utilities
