About Webacus
Webacus is a web-based collection of tools for developers. The homepage lists 145 tools across categories including encoding, compression, formatting, hashing, authentication, serialization, cryptography, date and time, text, number conversions, and arithmetic. Users can find tools with a built-in filter, save favorites in a custom list, and compose several tools into a workflow that runs at once.
Tools can be chained so that the output of one feeds the next without copying and pasting. Files can be dropped or uploaded, a tool applied to them, and the result saved back to a file. The homepage also describes an AI Assistant that generates a custom tool from a text description of the task. The homepage states that Webacus does not store user data on its servers. Uploaded files and any external services are not described in detail, so the privacy statement should be read as the company's own claim. Pricing is not stated on the homepage.
