CalcTide is a free online calculator site built for fast, trustworthy answers. It covers more than 100 tools across finance (mortgage, refinance break-even, 401k, loan, compound interest), health and fitness (BMI, TDEE, calorie, macro), math and education, time and date, construction and home (square footage, concrete, paint), and unit conversions.
What sets it apart: every formula is unit-tested before it goes live, and each tool explains how the result is calculated rather than just printing a number. There is no signup, no paywall, and the site works on any device. Built by MavenUp.

CalcTide's answer:
CalcTide gives a clear answer and then shows how it got there. Each tool explains the formula and the steps behind the result instead of just printing a number. Every calculation is unit-tested before it goes live, so the math is reliable. There are more than 100 calculators across finance, health, math, time, construction, and unit conversions, all free with no signup and no paywall.
CalcTide's answer:
CalcTide is built with Next.js and React, styled with Tailwind CSS, and written in TypeScript. The calculation logic lives in pure, unit-tested functions. The site ships as a static export hosted on Cloudflare Pages, which keeps it fast and reliable.
CalcTide's answer:
CalcTide is fast, free, and built to answer one task per page without clutter. Most calculator sites bury a simple result under ads and never explain the working. CalcTide leads with the answer, shows the formula and a worked example, and keeps the page light on any device. No account is needed, and there is no paid tier.
CalcTide's answer:
Every day, people need a quick, reliable number to make a real decision. That includes homebuyers running mortgage and affordability calculations, students working through algebra and geometry, people tracking fitness and nutrition, and homeowners planning construction projects such as concrete, paint, and flooring. It also serves small business owners by checking margins, markup, and ad metrics.
CalcTide's answer:
CalcTide was built by MavenUp out of frustration with calculator sites that hide a simple answer behind ads and never show the math. The goal was a free site where every tool solves one task clearly, explains how it works, and loads fast on any device. It launched in 2026 and continues to grow by adding the calculators people actually search for.
I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago
I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago

In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / about 1 year ago
