101 single-purpose tools run entirely in the browser, each covered by an automated test suite.

Website and tool interfaces · Directory data model and build · Editorial and indexing scripts

Utility sites compete on search. Growing beyond the tools meant adding a directory where every listing is complete and verified before it is published, so the site grows in quality rather than volume.
101 single-purpose tools run entirely in the browser, each covered by an automated test suite.
Listings are JSON validated against a schema: name, website, category, tagline, editorial description, pricing, features, alternatives and dated sources. A build script renders category and listing pages and adds a listing to the sitemap only once it passes a completeness gate.
Comparison articles and guides support the tools and the directory. Scripts submit new pages to Google and IndexNow and keep the sitemap current.
Counters, converters, formatters and generators.
Finance, time, unit and file conversions.
Compression, conversion, merging and splitting in the browser.
Accounts payable, accounts receivable, SaaS spend, sales commission, sales tax and VAT, subscription analytics.
Pricing, features, platforms, alternatives and vendor information, with a claim route for vendors.
141 guides, roundups and comparisons.
A static site with 101 tools, 141 articles and a directory of 85 verified listings across six software categories, published through a gated build.
