See Nitro in action

Real OpenCart stores running Nitro. Visit them and see the difference in speed.

Why it matters

A slow store is a smaller store.

Every OpenCart page view boots the framework, resolves your modules, runs the database queries behind them and renders the theme — then does the whole thing again for the next visitor. Most of that work produces exactly the same HTML it produced a second ago.

Nitro does that work once and then stops repeating it.

What's inside

All the speed OpenCart needs. In one extension.

Page Cache

Cached pages are served from disk before OpenCart boots. No database, no modules, no theme.

Read more

Query & Data Cache

Storefront SELECT results cached with per-table invalidation, so a write drops only that table's cached reads.

Read more

Assets

Minified and bundled CSS and JS, critical CSS, deferred scripts, resource hints and prefetching.

Read more

Images

WebP generation hooked into OpenCart's own resizer, explicit dimensions to stop layout shift, and LCP preloading.

Read more

Protection

A pre-framework request firewall, bot throttling, reverse-DNS verification of crawlers, and admin login lockout.

Read more

Warmer

A cron crawler that rebuilds the cache as a guest, seeded from real traffic and each page's own links.

Read more

Dashboard

Recommendations ranked by severity, hit-ratio history, a live traffic monitor and slow-query logs.

How it differs

A cache built specifically for OpenCart.

It answers before OpenCart loads
On a cache hit the finished page is served without running the whole of OpenCart, its modules and its database queries. That is where most of the response time is won.
Smart cache clearing
Edited a product? Nitro clears only the pages it affects and queues them again for the cache warmer. The whole cache does not have to be emptied on every change.
The store keeps working even if something goes wrong
If Nitro hits an error, the request falls through to stock OpenCart. Because speed should never come at the cost of reliability.
Cache even for logged-in customers
With Dynamic Fragments, Nitro can use the shared cache for logged-in visitors too, keeping their cart and account details live, filled in server-side before the page is sent. You get the performance without personalised pages being stored in the cache.
No telemetry, ever
Nitro never tracks your shoppers and never sends their data anywhere. The cache, the logs and the statistics all stay on your own server, where only you can read them.
Your crawlers keep crawling
Nitro never blocks a visitor or a crawler on its own. The firewall is yours to configure, and real crawlers are confirmed by reverse DNS instead of guessed from a user-agent string — so Google, Skroutz and BestPrice keep reading your store.

Compatibility

What it needs

  • OpenCart
  • Whatever PHP your store already runs — running the highest version your host offers is recommended
  • Ordinary shared hosting is fine — no Ioncube, no extensions to install
  • A cron entry, if you want the cache warmed automatically

Installing

Three steps

  1. 1 Upload the ocmod archive through Extension Installer.
  2. 2 Refresh Modifications.
  3. 3 Install Nitro from the module list — that's what starts your 7-day trial.

Try it on your own store.

7 days, no account, no card. If it does not help, uninstall it.
