Micro tool websites, shipped fast

I turn small tool ideas into live, usable web pages.

Need a calculator, converter, checker, or simple generator for your niche site, blog, SaaS, or lead magnet? I build lightweight static tools that are fast, responsive, SEO-friendly, and easy to deploy.

Small scope, real output.

This is not a full SaaS build. It is a focused service for people who need one useful tool page that can be launched quickly.

Calculators

ROI calculators, fee calculators, savings calculators, pricing calculators, revenue estimators, score calculators, and spreadsheet-based formulas.

Converters

Unit converters, file-related tools, marketing URL builders, gaming calculators, format helpers, and niche workflow utilities.

Checkers and generators

Small browser-based tools that validate, preview, generate, or clean up user input without needing a backend.

Recent examples

These are small utility sites built with the same static workflow I use for client projects.

Simple starter pricing

Intro prices are intentionally small while I build more public case studies. Scope stays tight so delivery stays fast.

Basic $39

One simple calculator, converter, or checker with up to 3 inputs and 1 main result.

Premium $149

Polished design, up to 10 inputs, SEO copy section, privacy/terms pages, and launch copy draft.

Not included: backend systems, user accounts, payments, databases, scraping, complex API integrations, or unlimited revisions.

How a small project works

1

Define the tool

You send the formula, inputs, expected output, examples, or a rough idea. I help narrow the first version.

2

Build the page

I create a responsive HTML/CSS/JavaScript tool that works as a static site or deployable page.

3

Deliver files

You receive deploy-ready files or a zip suitable for Cloudflare Pages, Netlify, Vercel, or similar static hosts.

FAQ

What do you need to start?

A short description of the tool, the inputs, the output, and any formula or example you already have.

Can you deploy it for me?

I can prepare deploy-ready files and guide you through Cloudflare Pages, Netlify, or Vercel. Direct account access is optional and not required for most projects.

Do you build full apps?

Not under these starter packages. This service is for small static tools, not full SaaS products with accounts, payments, or databases.

How fast can you deliver?

Most small tools can be delivered in 2-4 days after the scope is clear. More complex tools may need a custom estimate.

Start small

Have a formula or tool idea?

Send the idea, example, or spreadsheet. I will reply with whether it fits a small static build and which package makes sense.
