Any website - any time - from any language TO YOURS.

A browser inside your browser that makes the entire web readable in your oanguage

Every browser has a mark. This is ours. A browser inside a browser.

The wheel carries every wagon as it migrates into the new web.
The spokes are the Web2 handles that keep the web working.
The axle is what binds the spokes to the wagon.
Jit-Browser is the axle new fitting that keeps your wagon strong,
never left behind as the digital Oregon and Santa Fe Trail keeps moving.

A browser inside your browser - always a way forward, in any language.
The "win" is the path you see when you never give up".

Web 4 as a browser subsystem, not just a script

Here we describe what happens when pur patent-pending code runs alongside the iChrome Browser layout engine, iits JavaScript engine, and the network stack, instead of living as "yet another script" on the page. inside our server - or your server - or the client's browser.

β Great eadless capture today. Fast eadless capture tomorrow. Lightning-fast browser layer if integrated inside browsers like Chrome or HarmonyOS.

What Jit-Browser does in plain language

Jit-Browser is a headless browser pipeline that
is activated when a page from any websiote is requeted / before it is delivered using our proprietary decision rules.

  • Launches a real Chrome engine inside a container
  • Loads that EXACT page exactly like a user would (HTML, CSS, JS, fonts, images)
  • Injects our patent-pending JS code from api.jit-tr.com
  • Performs our JS codein place (for example to ES-419 and Ai/AEO)
  • Captures the final modified DOM as a static HTML snapshot
  • Delivers that static HTML snapshot

On our site - or on yours - or inside a browser.

It is this same architecture Jit-TR uses on real sites, but run headless, with timing logs that show exactly where the time goes.

One capture, step by step

1. Container + Chrome Start Docker, start headless Chrome, attach Puppeteer.
Typical cost: about 8–15 seconds on a cold start.
2. Page load Load HTML, CSS, JS bundles, fonts, and images for the target site.
Typical cost: about 8–15 seconds for heavy sites.
3. Jit API boot Inject the Jit API code, choose language (for example ES-419), and initialize.
Typical cost for full/first time / integration: around 1–3 seconds. Typical cost for fewer tah 10 edits: around 0.01 seconds.
4. Flow / click helpers Optional: accept a cookie banner, click “load more”, or scroll to reveal content.
Cost depends on the flow, often around 0.01 seconds.
5. Screenshot and HTML dump Optionally take a full-page screenshot and write the translated HTML to disk.
Typically around 0.01 seconds each.
6. Safety waits Short fixed waits to ensure all async translation and DOM updates have finished.
Usually around 0.1 seconds total.

In total, a cold capture of a large site lands around 5–15 seconds. Most of that is the cost of starting a fresh browser engine inside a container.

That is disipated if the Docker, headless Chrome, and Puppeteer remains active as a daemon.

That is DISAPPEARS if Jit API is embedded in a Browser!

Cold vs warm vs native browser layer

The same pipeline looks very different depending on where it runs:

Cold headless run (today)

  • Start Docker for each capture
  • Start Chrome headless for each capture
  • Reload all assets each time
  • Inject Jit-TR and translate

Typical: 25–35 seconds for one HarmonyOS capture.

Warm “sleep mode” container

  • Reuse a long-lived container
  • Reuse a single Chrome instance
  • Reuse cached CSS, JS, fonts, and images
  • Only change the translated HTML

Typical: 8–12 seconds once warm for the same page.

Native browser subsystem

  • No Docker at all
  • No separate Chrome process
  • Reuse the browser's built-in cache
  • Jit-TR runs inside the engine as a multilingual layer

Incremental overhead: milliseconds, not seconds.

Jit-Browser is a realistic demo of how a built-in multilingual layer would behave if browsers gave it a seat next to layout, JS, and the network stack.

Sample timing trace from a real capture

This is what a real headless timing trace looks like when capturing HarmonyOS in ES-419:

[URL] Page URL for capture: https://www.AnyWebsite/
[SNIPPET-URL] https://dev.api.jit-tr.com/?jittr=ES-419
[CSP] Bypassing page CSP for this capture session

[TIME] t0 start : +     0 ms
[TIME] t1 launch : +  6200 ms   (Δ launch =   6200)
[TIME] t2 goto   : + 17200 ms   (Δ page load = 11000)
[TIME] t3 inject : + 19250 ms   (Δ Jit-TR boot = 2050)
[TIME] t4 flow   : + 19260 ms   (Δ flow = 10)
[TIME] t5 shot   : + 20500 ms   (Δ shot = 1240)
[TIME] t6 html   : + 21550 ms   (Δ html = 1050)
[TIME] t7 done   : + 23550 ms   (Δ final wait = 2000)

[PAGE] log [Jit-TR] Language chosen → ES-419
[PAGE] log calling:https://dev.api.jit-tr.com/files/translateDocument.php
[PAGE] log calling setFlags
[PAGE] log calling setStore
[HTML] Writing to output/ES-419/index.php

The trace makes the point very clear: the slow part is not the translation, it is the cold start of a full browser stack in a container. Move the same logic into the browser engine, and most of that cost disappears.

Deep dive details

How “Warm Mode” makes Jit-Browser fast

Today’s demo loads each page the hard way:

  • Start Docker
  • Start Chrome headless
  • Load the site fresh
  • Inject Jit-TR
  • Translate and capture
  • Shut it all down again

This is the equivalent of shutting down a laptop, turning it back on, opening the browser, and visiting a site for every single page. Cold-start captures land roughly around 25–35 seconds on typical hardware.

Warm Mode (“Sleep Mode”)

Instead of rebooting everything, Jit-Browser can keep a warm headless Chrome running in the background:

  • Docker container stays alive
  • Puppeteer and Chrome stay loaded
  • Tabs remain open or reusable
  • Browser cache stays warm (fonts, CSS, JS, images)

Each new request becomes nearly instant compared to a cold boot:

  • No Docker startup
  • No Chrome startup
  • Cached HarmonyOS or Huawei assets load from disk
  • Only the translated HTML changes

Warm-mode captures typically drop from about 30 seconds to around 8–12 seconds.

Why this matters

Browsers already have native layers for:

  • JavaScript execution
  • HTML layout
  • Network stack
  • Accessibility tree
  • GPU rendering

Jit-TR behaves like a missing native layer: a multilingual layer. Warm Mode shows how fast it could be if translation ran inside the browser engine directly instead of as an external script.
