Every time you want to format a piece of JSON, debug a JWT token, compress a PDF, or erase a photo's background, you make a compromise. You upload your proprietary files or sensitive API keys to a random server, hoping they won't log it.
As a developer, I asked myself: Can we build a hyper-scalable ecosystem of professional tools that run 100% in the browser, protect user privacy, and maintain absolute zero compulsory server costs?

Building 90+ separate interactive applications within a single Next.js codebase without causing compilation chaos or catastrophic bundle sizes required sticking strictly to a "local-first" philosophy.
