No. Every tool runs entirely in your browser. Nothing you type, paste, or upload is sent to any external server — making it safe to use with sensitive configs, API keys, internal payloads, and production data.
Click the heart icon on any tool to save it to your Favorites. Your saved tools appear at the top of the Home page for quick access. You can save up to 9 favorites, including custom links you add yourself — all stored locally in your browser.
The AI Prompt Launcher lets you write a prompt once and open it directly in ChatGPT, Claude, Gemini, or Perplexity in a new tab — prefilled and ready to go. No copy-pasting between tools.
Tools are interactive — UUID generators, JSON formatters, SQL builders, and more. References are static cheat sheets you can bookmark — HTTP status codes, Git commands, JSONPath syntax. Articles covers practical technical articles on web development, AWS, and developer workflows.
No. The site is intentionally ad-free. No banners, no trackers, no distractions — just tools and content.
