webacus.devAbout Webacus
Webacus is a single web app that replaces the folder of one-off developer utility sites most engineers accumulate in their bookmarks — 145 tools covering encoding and decoding for Base64, URL, hex, HTML, JSON escaping, data URLs, quoted-printable, MIME words and form-urlencoded payloads, alongside the usual hashing, formatting, conversion and generation helpers. Two design decisions lift it above a link directory. The first is chaining: tools compose, so the output of one feeds directly into the next and results cascade without copy-pasting between tabs, which is the actual workflow when you are unpicking a nested encoded payload. The second is an AI assistant that generates a tool that does not exist yet — describe the transformation you need and Webacus builds the custom operation on the spot, so the catalogue is a starting point rather than a ceiling. History keeps past operations retrievable, capped on the free tier and unlimited on Pro. The free plan is restricted to non-commercial personal use and shows ads; the Pro licence is what grants commercial use, which is a cleaner line than most utility sites draw. Built by a solo developer in Slovenia. Testimonials come from named engineers at DG1 and PROGMBH describing it as replacing their bookmarked tools folder, and the version string is published in the footer.
