About DevTools Directory
We build free, browser-based developer tools and technical guides for the AI era. No paywalls, no signups, no tracking.
Our Mission
DevTools Directory was founded with a simple goal: make high-quality developer tools and technical education accessible to everyone. Whether you're estimating the cost of an LLM API call, figuring out how much VRAM you need to fine-tune a model, or building a structured prompt for a production application, we want to be your first stop.
What We Build
Our platform has three core pillars:
- Interactive Tools: 9 browser-based calculators and utilities for AI development workflows. All run client-side — your data never leaves your browser.
- Technical Guides: 2 in-depth technical articles covering AI systems, autonomous agents, and model infrastructure.
- Structured Directory: 5 curated categories that make it easy to find exactly what you need.
Our Principles
- Free and open: All our tools and guides are free to use. No paywalls, no signup walls.
- Privacy-first: Our tools run entirely in your browser. We don't collect, store, or sell your data.
- AI-optimized: Our content is structured for both human readers and AI search engines, with JSON-LD schemas and clear Q&A formats.
- Accurate and current: We update our tool data regularly to reflect the latest pricing and specifications.
Who We Are
Our team consists of experienced software engineers, AI researchers, and technical writers who have worked at companies ranging from early-stage startups to large enterprises. We've built production AI systems, optimized cloud infrastructure, and shipped products used by millions of developers.
