    tl;dr we at Escape (YC W23), we scanned 5651+ public APIs on the internet with our in house feedback driven API exploration tech, and ranked them using security, performance, reliability, and design criteria. The results are public on https://apirank.dev. You can request that we index your own API to the list for free and see how it compares to others. Why we did that? During a YC meetup I spoke with a fellow founder that told me how hard it was to pick the right external APIs to use within your own projects. I realized that most of what we build relies on public APIs from external…

    I started writing this book 10 years ago in JavaScript, got through a few chapters (asymptotic notation, basic techniques, start of sorting), and then abandoned it. Recently I picked it back up, converted everything to TypeScript, and used AI (Zenflow [1] + Claude Opus 4.6) to complete the remaining chapters. I provided the structure, direction, and initial chapters; the AI generated the bulk of the remaining content under a spec-driven workflow. The book covers roughly a first 1-2 year CS curriculum: sorting, dynamic programming, graph algorithms, trees, heaps, hash tables, and more. All…

    I built devtool.io over a weekend to solve a recurring pain point: discovering and keeping track of high-quality developer tools. I've lost count of how many times I've bookmarked a great CLI, API tester, or AI tool—only to forget where I saw it. DevTool.io is a minimal, searchable directory where developers can find and compare tools by category (CI/CD, Frontend, AI/ML, Databases, etc.), see what's trending, and browse curated picks. Each tool includes metadata like website, GitHub, category, and tags (open-source, freemium, etc.). Feedback, ideas, or tool suggestions are all…
