What is Caniveto
Caniveto is a growing collection of online utility tools that run 100% in your browser. Brazilian document generators and validators, developer formatters, labor calculators, financial simulators — all in one place, no signup, no invasive ads, no data sent anywhere.
The name comes from canivete suíço — Portuguese for "Swiss Army knife": small, practical, always at hand.
Why it exists
There are plenty of "online tools" sites. The problem is that most:
- Send your data to the server (bad privacy);
- Have pop-up ads screaming on every square cm (terrible UX);
- Mix serious tools with SEO traps (no trust);
- Lack dark mode, decent mobile, or multilingual support;
- Go live once and stay abandoned.
Caniveto was born as a reaction to that. Every tool processes everything locally: CPFs you generate, JSON you format, severance you simulate — none of it leaves your browser.
How it works technically
The site is static, hosted on Cloudflare Pages edge. When you load a page, HTML/CSS/JS come from the nearest CDN node (typical latency sub-100ms). All computation happens in your own browser via JavaScript.
Stack: Astro framework, Tailwind CSS, Alpine.js for reactivity, Web Crypto API for hashes and JWT. No heavy React, no massive hydration — JavaScript only where needed.
Who operates it
Caniveto is developed and maintained by Linksoft Tecnologia LTDA (CNPJ 37.534.981/0001-67), a Brazilian software company based in Mossoró. Linksoft is also the developer of Sigeflex, a fiscal SaaS ERP for Brazilian SMBs.
Business model
Caniveto is and will remain free. Operating costs are covered by:
- Non-intrusive ads via Google AdSense or Ezoic, positioned not to interfere with tool usage;
- Linksoft sponsorship — the project is part of the company strategy.
We will never sell your data. We don't have your data — it never leaves your browser.
