About Toolvana

Tools that respect you.

Toolvana is a free, privacy-first collection of 196+ browser-based utilities. Built and maintained by Aravind Labs from Bengaluru, India.

Why Toolvana exists

The web is full of "free" tool sites that aren't really free. They limit you to 3 uses per day. They demand your email. They keep your file on their server "for processing convenience" — and quietly use it to train models, sell to data brokers, or both. They redirect you to a paid plan the moment you do anything useful.

Toolvana exists to be the opposite. Every tool is fully functional, forever free, and runs entirely in your browser. We don't have a server that sees your files because we don't have a server that processes your files. The site is a static collection of HTML, CSS, and JavaScript — your browser does all the work, your CPU does all the compute, your storage holds all the data.

How it's built

Toolvana is intentionally low-tech under the hood:

  • No build step. Plain HTML, plain CSS, plain JavaScript. View the source of any page and you'll see exactly what runs.
  • No framework. No React, Vue, or Angular bloat. Just modern vanilla JavaScript and the web platform.
  • CDN-only libraries. We use proven open-source libraries (pdf-lib, marked, transformers.js, Pyodide, sql.js, MediaPipe) loaded from public CDNs.
  • Caddy reverse proxy serving static files from a single VPS in India.
  • No accounts, no database. The site has no users in any technical sense — everyone is anonymous.

How it's paid for

Server hosting (~₹2,000/month) and domain renewal (~₹1,000/year) are paid by Aravind Labs out of pocket. We are applying for Google AdSense to offset costs — ads will appear only on browsing pages (homepage, category lists, About/Privacy) and only after you accept on the consent banner. Tool pages themselves stay ad-free. If AdSense is rejected, the site continues as before — Aravind Labs absorbs the cost.

There is no premium tier planned. There is no paid version. There are no "Pro features". Every tool stays free for every user. Forever. If we ever need to gate something, it will be a brand-new tool with very high compute cost — and existing tools stay free.

Who built it

Toolvana is a project by Aravind, a software engineer based in Bengaluru, India. Aravind Labs (aravindlabs.tech) is the parent brand and hosts several projects:

  • Toolvana — this site, 196+ free browser tools.
  • ReplX — AI-powered REPL.
  • Phantom — open-core SaaS.
  • VisionX — AI vision playground.
  • Pyro — experimental programming language.
  • VoltX — DeFi trading bot.
  • ForexBot — AI forex trading.
  • Meridian One — credit card simulator.

Trust signals

  • Open source — at least visually. View the source of any page in your browser to see exactly what runs.
  • No data leaks possible. Tools have no server-side component, so there is no database to be breached, no email list to be sold.
  • Domain ownership. toolvana.aravindlabs.tech is a subdomain of aravindlabs.tech — the parent domain is registered to Aravind Labs (verifiable via WHOIS).
  • HTTPS with HSTS. TLS 1.3, valid certificate from Let's Encrypt, enforced via HTTP Strict Transport Security.
  • Hosted in India. Server runs from an Indian VPS. Lower latency for Indian users, data sovereignty compliance.
