The Online Toolkit - Tools for Science

What it does

An free online repository of science tools and calculators for chemists, physicists, and engineers, including molarity calculators, metal complex builders and more, built by chemistry students. The website is constantly evolving and expanding as more tools are added and new functionality is developed. The goal of TheOnlineToolkit is to develop niche scientific tools not currently available on the web, and to provide quality scientific resources for students, teachers and academics.

  500+ Free Online Tools In One Place – developers, designers, studentsNov 2025 · everytoolkit.com · ▲11

  I built EveryToolkit.com — a collection of 500+ free online tools across 24+ categories, all in one clean, fast, and ad-supported site. The goal is to make small, everyday utilities accessible from one place — no popups, no clutter. You’ll find: • Developer tools (JSON, JWT, regex, base64, etc.) • Text and writing tools (word counters, formatters, case converters) • Image & PDF tools (compress, convert, merge) • Finance, health, and SEO utilities • Calculators and converters for daily use I built this to solve my own frustration of having to Google for “that one tool” every time. Would love…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
