Install the Chrome extension.
Vectorcart is a Chrome MV3 extension. It installs from a local folder — no Chrome Web Store required. This takes under two minutes.
1
Purchase and access on Whop
After checkout, Whop grants access to your Vectorcart member content. Your license key and download files are in your Whop dashboard under My Products.
2
Download and unzip the extension
Download the ZIP for your plan (Basic or Pro). Unzip it to a permanent folder — do not delete this folder after loading. The unzipped folder must contain manifest.json, pages/, scripts/, and icons/.
3
Open Chrome Extensions and enable Developer mode
Navigate to chrome://extensions in Chrome. Toggle Developer mode ON in the top-right corner.
Developer mode is required to load extensions from a local folder. This is a standard Chrome feature, not a security risk.
4
Load unpacked
Click Load unpacked (top-left). Select the unzipped Vectorcart folder — the one that contains manifest.json directly inside it. If Chrome shows an error, re-check that you selected the correct folder level.
5
Pin to toolbar
Click the puzzle piece icon in Chrome's toolbar → click the pin icon next to Vectorcart. The icon now appears in your toolbar for quick access.
6
Open the dashboard
Click the Vectorcart icon → Extension options, or navigate to chrome://extensions → Details → Extension options. The dashboard opens as a full-page tab.
Activate your license key.
1
Open the License tab
In the extension dashboard sidebar, click License.
2
Paste your key and activate
Enter your license key in the format V-XXXX-XXXX-XXXX-XXXX and click Activate. Status changes to LICENSE: ACTIVE (green).
Your key is validated against Whop and locked to your device. Use Deactivate to move it to another machine.
3
Complete the First Win Sprint
The License page shows a First Win Sprint card with 5 guided steps: activate → confirm backend → create profile → create task → run first task. Follow these in order before exploring advanced settings.
Create a checkout profile.
Profiles store your shipping and payment details, encrypted locally with AES-GCM so your card data is never stored in plain text.
1
Set an encryption passphrase
Go to the Profiles tab. A banner will prompt you to set a passphrase. Enter a strong passphrase and click Set Passphrase. You'll re-enter this each time Chrome restarts.
2
Create a profile
Click Create Profile. Fill in your Shipping Details (name, address, city, state, ZIP, country, phone) and Payment Details (card number, expiry MM/YY, CVV). Click Save. Card data is encrypted immediately.
Create and run your first task.
A task is one monitoring + checkout job targeting a single product URL. Each task cycles through: IDLE → RUNNING → CHECKING → IN_STOCK → CHECKOUT → SUCCESS / FAILED.
1
Open Tasks and create
Go to the Tasks tab and click Create Task.
2
Configure the task
Enter the Product URL (direct product page). The Site auto-detects from the URL. Assign a Profile. Set the Monitor Interval in seconds.
3
Choose a speed preset
Safe Mode
30s interval · Sniper off. Best for first-run validation and lower detection risk.
Sniper Mode
5s interval · Sniper on. Auto-checkout fires the moment stock is detected.
4
Save and start
Click Save, then Start. The task row shows live status. Use the search bar and filters at the top of the Tasks section to find tasks by name, site, or status.
Set up proxy groups.
Proxies route monitoring requests through different IP addresses, reducing the risk of rate limits and IP bans during high-volume polling. They're optional but recommended for competitive drops.
Create a Proxy Group
- Go to the Proxies tab → Create Group
- Name your group
- Paste your proxy list, one per line:
host:port:username:password - Choose a rotation strategy
- Assign the group to tasks at creation time
Rotation Strategies
- Round-Robin — cycles in order
- Random — random pick each request
- Least-Used — always picks least-recent
- Fastest — picks lowest measured latency
- Sticky — same proxy per checkout session
The Smart Proxy Mesh automatically quarantines proxies that fail consecutively on a specific site. The Proxy Heatmap shows per-site performance scores so you can see which proxies work best per retailer.
Configure CAPTCHA solving.
Vectorcart uses a three-tier CAPTCHA pipeline. Tier 1 auto-clicks iframe checkboxes. Tier 2 calls an external solver API. Tier 3 pauses for manual solving. Supported types: hCaptcha, reCAPTCHA v2, Cloudflare Turnstile.
Enable external solving
- Create an account on 2Captcha, CapMonster, or CapSolver
- Go to Settings → CAPTCHA Solver
- Select your provider and paste your API key
- Click Check Balance — warning appears below $2.00
Without a solver configured
Tier 1 (auto-click) still runs on every CAPTCHA. If it fails, the task pauses and waits for you to solve it manually. External solvers are recommended for unattended drops.
Set up Discord notifications.
Receive real-time alerts for checkout successes, failures, and restocks directly in a Discord channel.
1
Create a Discord webhook
In Discord: Edit Channel → Integrations → Webhooks → New Webhook → Copy Webhook URL.
2
Paste into Settings
Go to Settings → Discord Webhook URL, paste the URL, and click Test to verify delivery.

Common issues and fixes.
License shows UNAUTHORIZED
Re-paste your key with no extra spaces. The format must start with
V-. If purchased via Whop, find your key in My Products.Load unpacked fails in Chrome
Verify you selected the folder that contains
manifest.json directly inside it — not a parent folder or a nested subfolder."Backend not connected" banner appears
This is normal when running standalone. Basic tasks, profiles, and proxies work without the backend. Discovery, Analytics, ACE, and Replays require the backend to be running.
Task immediately shows FAILED
Check the History tab for
monitor_blocked or checkout_fallback events. Check the ACE tab for error patterns. Open the Replay for that session to see exactly which step failed.CAPTCHA loop — task never completes
Check your CAPTCHA solver API key and balance in Settings. If balance is below $2.00, top up the account. Without an external solver, you may need to solve CAPTCHAs manually.
Profile not autofilling on checkout page
Confirm your encryption passphrase was entered after the last Chrome restart. Go to Profiles and unlock profiles with your passphrase before running tasks.
Discord alerts not arriving
Go to Settings and click Test on the webhook URL. Verify the URL starts with
https://discord.com/api/webhooks/. Confirm the Discord channel is accessible to the webhook.Proxy 403 / 429 rate limit errors on tasks
Add proxy groups and assign them to your tasks. Check the Proxy Heatmap for quarantined proxies. Try switching the rotation strategy to Fastest to use your best-performing proxies more often.
