Toolivaro vs Omni Calculator: measured speed, privacy, translations
Three claims are easy to make and easy to fake: that a site is fast, that it is private, and that it is fully translated. This page compares Toolivaro against Omni Calculator, the reference calculator platform, using measurements and configuration instead of adjectives. Everything here is verifiable — the numbers come from a public measurement round described below, run on the same machine, the same day, with the same settings for both sites, and every claim about scripts and pages can be checked against the live site.
One thing we are not going to claim: that we have more calculators. Omni Calculator has a vastly larger catalog, and it has earned its position with years of coverage. This comparison is about the tools both sites publish, and about what you give up — or keep — when you use a calculator site. For the tools we both cover, the measurements below are ours to report; if you would rather test both sites yourself, the method is on this page.
Measured performance, same settings for both
On 2026-08-12 we ran Lighthouse 12.6.1 (mobile profile, simulated (Slow 4G) throttling, 3 runs per URL, median shown) against the production pages below, and against the same page types on Omni Calculator under identical conditions.
| Performance score (0–100) | Toolivaro — Home page | Toolivaro — Calculator page | Toolivaro — Blog post | Omni Calculator — Home page | Omni Calculator — Calculator page |
|---|---|---|---|---|---|
| Performance score (0–100) | 93 | 90 | 93 | 54 | 35 |
| Largest Contentful Paint | 2.6 s | 2.9 s | 2.6 s | 13.6 s | 20.3 s |
| Cumulative Layout Shift | 0.00 | 0.001 | 0.002 | 0.003 | 0.004 |
| Total Blocking Time | 10 ms | 10 ms | 10 ms | 390 ms | 920 ms |
| Page weight | ~496 KiB | ~517 KiB | ~471 KiB | ~1,698 KiB | ~2,861 KiB |
| Network requests | 25 | 33 | 21 | 86 | 122 |
Two honest caveats. First, these are single-machine measurements from one location: absolute numbers will differ on your network, and Core Web Vitals collected from real visitors (the numbers Google actually uses) are published separately where available. Second, Omni Calculator was measured as its pages were served to this machine on that day — their script and ad stack varies by region and consent state, so their numbers are a snapshot, not a verdict. We report the same metric set for both, and we do not round in our favor.
Zero analytics scripts
No page ships an analytics script. There is no Google Analytics, no Google Tag Manager, no
consent-gated tracker that quietly turns on later — the analytics provider is compiled to
none in this build, and the typed adapters that exist for later enablement are never
loaded without consent. The only third-party script that can load anywhere on the site is the
ad script on ad-enabled pages, which is a build-time switch (off in CI and preview builds) and
never loads on blog or editorial pages unless the slot gates pass.
The rest of the interactivity is deliberate: share links, PDF/CSV export, the JSON and Base64 workspaces, and every calculation run entirely in your browser. No keystroke, no calculation, and no exported file ever leaves your device. The strict Content-Security-Policy header (hash-based inline scripts, no third-party origins except the ad domains) is served on every page and is part of the build.
100% of tools, six languages
Every calculator — all 44 tools across business, developer, home, image, math, and time categories — exists in English and in all five translated locales: Spanish (Spain and Latin American variants), Brazilian Portuguese, French, German, and Japanese. That is 100% coverage per locale, not a subset: the hreflang alternates, sitemaps, and language switcher only list locales that actually exist, so nothing links to a half-translated page. Editorial pages, the changelog, the blog, and every collection page follow the same rule.
How these numbers were measured
The measurement round used Lighthouse 12.6.1 in headless
Chrome, mobile form factor, simulated throttling (Slow 4G), 3
runs per URL with the median reported. The same settings are committed in the repository's
lighthouserc.json and gate CI builds (performance must score 90+ on localhost).
Production numbers are lower than localhost numbers because they include real edge and network
latency — we publish the production numbers. The full site methodology, calculation standards,
and correction policy are on the methodology page.
Frequently asked questions
Is Toolivaro faster than Omni Calculator?
In the measurement round described on this page — Lighthouse on the same machine, same day, same throttling, same metric set for both sites — every Toolivaro page type loaded faster than the matching Omni Calculator page: higher performance scores, lower LCP, smaller page weight, fewer requests. Two honest caveats: these are single-machine measurements from one location, and Omni Calculator's numbers are a snapshot of what that site served on that day. We publish the full methodology so you can re-run the comparison yourself.
Does Toolivaro have fewer calculators than Omni Calculator?
Yes, and we do not hide it. Omni Calculator has a much larger catalog. Toolivaro deliberately publishes fewer tools — 44 calculators, converters, and developer tools — each with full editorial content, worked examples, sources, and translations into five languages beyond English. The catalog grows steadily; coverage depth per tool is the product, not count alone.
Is Toolivaro really free, and where does the money come from?
Free, with no account, no paywall, and no tracking. The build is funded by a small number of ad slots on tool pages, which never load on editorial pages and never load at all without your consent. There is no analytics script anywhere — no Google Analytics, no Google Tag Manager, no hidden trackers.
What does "100% of tools in six languages" actually mean?
It means every tool page exists in English and in all five translated locales — Spanish, Brazilian Portuguese, French, German, and Japanese — not a subset. The hreflang alternates, sitemaps, and language switcher only list locales that actually exist, so no link ever points to a half-translated page. Editorial pages, the changelog, the blog, and collection pages follow the same rule.
Can I verify these claims myself?
Yes. The measurement settings are committed in the repository's lighthouserc.json and the production numbers are published here as they were measured — we do not round in our favor. The full editorial methodology, calculation standards, source list, and correction policy are on the methodology page, and every calculation runs locally in your browser so you can check any result against a spreadsheet.
