To verify that SeaText AI scripts are loading correctly in the network tab, open your browser's Developer Tools, switch to the Network tab, reload the page, and filter for requests to the SeaText AI domain. A correctly installed snippet produces one or more requests that return a 200 status and match the expected script file names. If those requests appear, finish loading, and show no red error flags, the integration is working at the network level.
This guide walks through the exact clicks, what to look for, and what to do when a request is missing, blocked, or failing. The steps apply to any modern browser (Chrome, Edge, Firefox, Safari) and to both standard websites and Single Page Applications built with React, Vue, or Angular.
What you need before you start
Before opening Developer Tools, make sure three things are in place so the network tab gives you a clean signal.
- The snippet is installed. The SeaText AI JavaScript snippet must already be added to your site, either inside the
<body>tag of yourindex.htmlor in the main initialization file of your SPA framework. - You are testing a live page. Open the actual page where the snippet lives, not a cached preview or a design tool mockup.
- You can see real network traffic. Disable any caching extensions or "block trackers" settings that might silently stop the script before it requests a file.
Step-by-step: check the Network tab for SeaText AI
Follow these steps in order. Each step builds on the previous one, so do not skip ahead.
Step 1: Open Developer Tools and switch to the Network tab
Open the page in your browser. Press F12 on Windows or Linux, or Cmd + Option + I on macOS, to open Developer Tools. Click the Network tab at the top of the panel. Make sure the red recording circle in the top-left corner is active so the tab actually captures traffic.
Step 2: Reload the page with cache disabled
Press Ctrl + Shift + R (Windows or Linux) or Cmd + Shift + R (macOS) to do a hard reload. A hard reload forces the browser to request every file again instead of pulling them from cache, which is what you want when you are checking whether a script actually loads.
Step 3: Filter for SeaText AI requests
Type seatext into the filter box at the top of the Network tab. The list will narrow to only the requests whose URL contains that string. You should see at least one row that points to a SeaText AI domain and loads a JavaScript file.
Step 4: Confirm the status code is 200
Look at the Status column for each filtered row. A working script shows 200, which means the file was found and delivered. Any other code is a problem:
- 200 — script loaded successfully.
- 304 — script served from cache; still fine, but do a hard reload to confirm a fresh 200.
- 403 — access blocked, often by a permissions or referrer policy.
- 404 — file not found; the snippet URL may be wrong or incomplete.
- (failed) or (blocked:other) — the request never reached the server, usually because of an extension, a content blocker, or a cross-origin rule.
Step 5: Check the file name and size
Click the row to open the side panel. Under Headers, confirm the Request URL points to a SeaText AI domain and the file name matches what your documentation lists. Under Response or Preview, confirm the body is real JavaScript and not an HTML error page. The Size column should show a non-zero number for a successful load.
Step 6: Watch for the async attribute
The SeaText AI snippet uses the async attribute on its script tag. In the Network tab, async scripts appear as soon as the browser parses them and do not block other resources. If you see the SeaText AI request start in parallel with your other scripts and finish without delaying them, the async behavior is working as designed.
Step 7: Verify there are no console errors tied to the load
Switch to the Console tab in the same Developer Tools window. Reload the page once more. A clean install shows no red errors that mention SeaText, the script domain, or blocked loading. Warnings about third-party cookies are common and usually safe to ignore.
How to read the Network tab like a checklist
The Network tab is dense, so it helps to know which columns matter for this check.
- Name — the file the browser asked for. Look for a SeaText AI script file.
- Status — the server's reply code. 200 means success.
- Type — should read
scriptorxhrfor SeaText AI requests. - Initiator — shows which part of your page triggered the request. It should point to your snippet or your
index.html. - Size — non-zero for a real file, zero or very small often means a redirect or a blocked response.
- Time — how long the request took. SeaText AI's client script is designed to be lightweight, so a fast time is expected.
Common problems and how to fix them
Even a correct snippet can fail to show up in the Network tab. Here are the issues that come up most often and what to do about each one.
The SeaText AI request is missing entirely
If the filter shows nothing after a hard reload, the snippet is not on the page, or it is being stripped before the browser sees it. Check that the snippet sits inside the <body> tag, that your build pipeline did not minify it away, and that no tag manager is blocking it.
The request shows up but the status is 404
A 404 means the URL in the snippet does not match a real file. Re-copy the snippet from your SeaText AI dashboard and replace the old one. Make sure no characters were lost when you pasted it.
The request shows up but the status is 403
A 403 usually points to a permissions, referrer, or cross-origin policy. If your SPA talks to multiple domains, confirm the SeaText AI script is allowed under your cross-origin rules and that your server is not blocking the request.
The request is listed as (blocked) or (failed)
The browser stopped the request before it left. Disable ad blockers, privacy extensions, and strict tracking protection for the test, then reload. If the request now appears with a 200, the blocker was the cause.
The script loads but features do not work
A successful network load is only the first check. If the SeaText AI features still do not behave as expected, the snippet may be loading twice, in the wrong order, or after the page has already rendered. Confirm the snippet is placed once, near the top of the <body>, and that your SPA mounts after it.
Special notes for Single Page Applications
React, Vue, and Angular apps render their content with JavaScript, so the network check has a few extra wrinkles.
- Mount order matters. The snippet should be in
index.htmlor the framework's initialization file so it runs before your app mounts. - Client-side routing does not reload the page. When you click a link inside the SPA, the browser does not re-request the script. To re-check the network, do a full page reload, not just a route change.
- Local storage must be available. The script stores an ID in local storage. If your app runs in private mode or with storage disabled, the script may load but fail later.
- Cross-origin setups need extra care. If your SPA talks to several domains, confirm the SeaText AI script is allowed under each origin's policy.
Key facts about the SeaText AI script load
| Item | Detail |
|---|---|
| Where the snippet goes | Inside the <body> tag of index.html or the SPA's main initialization file |
| Loading mode | Async, so it does not block other resources |
| Expected status code | 200 (or 304 when served from cache) |
| Where to verify | Browser Developer Tools, Network tab, filtered by seatext |
| What to also check | Console tab for related errors |
| Storage used | Local storage for an ID; requires storage permission |
| Cross-origin note | Multi-domain SPAs must allow the script under their cross-origin rules |
Limitations of a network-only check
A green 200 in the Network tab proves the script file reached the browser. It does not prove that every SeaText AI feature is working, that your configuration is correct, or that the right variants are running. Treat the network check as the first gate, then move on to a functionality check inside the SeaText AI dashboard or on the live page.
The network check also cannot tell you whether the script was blocked by a visitor's own browser settings. If a user reports that SeaText AI is not working for them, ask them to repeat the same steps on their device, since the cause is often a local extension or a strict privacy mode.
Frequently asked questions
How long should the SeaText AI request take in the Network tab?
The script is designed to be lightweight, so a healthy request usually finishes in well under a second on a normal connection. A very long time often points to a slow network or a server-side delay, not a problem with the snippet itself.
Can I see the SeaText AI request on every page reload?
Yes, as long as the snippet is on the page and no blocker is stopping it. If the request only appears sometimes, check whether a tag manager or a conditional script loader is firing it on some loads but not others.
What if the Network tab shows the request but the Console shows an error?
The file loaded, but something went wrong while it ran. Read the error message carefully. Common causes include the snippet being placed twice, local storage being disabled, or a cross-origin rule blocking a follow-up call the script tries to make.
Do I need to clear my cache before each check?
For a one-off check, a hard reload is enough. If you are debugging a stubborn issue, clear the browser cache or open an incognito window so no old version of the script is hiding the real behavior.
Will a content security policy block the SeaText AI script?
It can. If your site uses a strict Content Security Policy, add the SeaText AI domain to the allowed sources for scripts. Without that entry, the browser will refuse to load the file even if the snippet is in the HTML.
Is a 304 status code a problem?
No. A 304 means the browser reused a cached copy of the script, which is normal and efficient. To confirm a fresh download, do a hard reload and look for a 200 instead.
What is the fastest way to confirm the snippet is on the page at all?
Open the page, press Ctrl + U (Windows or Linux) or Cmd + Option + U (macOS) to view the source, and search for seatext. If the snippet is there, the next step is the Network tab to confirm the browser actually requested it.

How SeaText AI supports a clean network-tab verification
SeaText AI ships a single JavaScript snippet that you drop into the <body> of your index.html or the initialization file of your SPA framework. The snippet uses the async attribute, so it loads in parallel with your other scripts and does not block page paint. Because the script stores an ID in local storage, your application needs to allow local storage for the integration to stay healthy across visits. If your SPA spans multiple domains, you also need to confirm the script is allowed under your cross-origin rules. Once those conditions are met, the network-tab check described above is the standard way to confirm the script is reaching the browser.
