Webacus

About Webacus

Webacus is a web-based collection of developer utilities covering encoding, compression, formatting, hashing, authentication, serialization, cryptography, browser-related lookups, date and time conversion, text manipulation, number conversion, and arithmetic operations. The site lists 145 individual tools, including Base64 and URL encoding/decoding, JSON/HTML/CSS/JS formatting and minification, SHA/MD hashing functions, JWT and HTTP Basic Auth encoding/decoding, PHP serialization conversion, User-Agent parsing, a Can-I-Use lookup, timestamp conversion, and case conversion utilities.

The tools can be chained together into workflows so output from one tool feeds into the next without manual copy-pasting. Additional features include a filterable tool list, a favorites list for quick access, a history of previous results, file upload/drop support for running tools on files, a built-in hex editor for binary data, a math expression evaluator/calculator, keyboard shortcuts, and import/export of tool configurations. The site states data is processed locally and not stored on its servers.

An AI Assistant feature lets users describe a tool they need in a prompt and have Webacus generate it. The product is aimed at web developers who repeatedly use small utility tools during development and want them unified in one interface instead of searching for separate tools individually. The site offers a free trial and has a pricing page, though specific plan details are not stated on this page.
