Why You Need a Relay Extension
The Amazon Relay load board refreshes when you reload it. Good loads book within seconds. Manual refreshing every 30 seconds isn't practical if you're driving, managing dispatch, or running your business. An extension automates the reload and notifies you or books loads for you, so you don't have to watch the screen.
There are dozens of extensions in the category. Some are robust, some are bare-bones, and some have been abandoned. Understanding what to look for helps you pick the right one.
What to Look For in a Relay Extension
Refresh Control: Can you set the interval (how often it reloads) and does it add jitter (random variation to prevent server strain)? A good refresher lets you choose 1–5 second intervals and includes built-in jitter so every refresh isn't at the exact same moment.
Booking Rules: Can you set rules to book only certain loads? Look for the ability to filter by lane, price range, load type, distance, and equipment. A tool that books only loads matching your criteria is safer than one that books indiscriminately.
Profit Floor and Max-Books Cap: Does it let you set a minimum profit and a maximum number of books? These guardrails protect you from booking loads you didn't intend to take. A profit floor means "don't book anything below $X net profit." A max-books cap means "stop booking once I've booked 5 loads today."
Rate Data and Decision Support: Does it show you lane history, net profit per load, or other rate context? Or does it just notify you when a load posts and let you decide? Tools that surface rate data help you make faster decisions.
Alerts: Can it notify you when a load matching your rules posts? Notifications can come via browser popup, email, SMS, or Telegram. Telegram alerts are common because they reach you even when your browser is closed.
Data Handling and Privacy: Where does your data go? Some tools store booking rules on your computer only. Others upload to a server. Ask yourself: do I want my lane preferences, profit targets, and booking history on someone else's server?
Updates and Support: Is the tool actively maintained? An extension that hasn't been updated in months might break when Chrome or Relay changes. Look for tools with recent updates and a way to report problems.
Cost: Free tools exist. Paid tools add more features. Decide whether the features are worth the cost for your operation.
The Top Extensions
LoadFetcher
LoadFetcher is the largest Amazon Relay extension by installs. It offers a free refresher and booker tier focused on the core features: refreshing the board automatically and booking loads that match your rules.
The free tier includes refresh control, booking rules, profit floor, and max-books cap. What's advertised: the refresher and booker. What's not advertised: lane rate history, net profit calculation, or scorecard dispute support.
LoadFetcher's pitch is simplicity and cost—you get a working refresher and booker for zero dollars. If you only need those two things, the free tier does the job.
Best for: Carriers who want a refresher and basic booker, nothing more, and prefer not to pay.
Rocket Relay and Rocket Pro
Rocket Relay is a refresher and booker with a free tier. Its core pitch is that your business data stays on your computer—no uploads to a server, no cloud storage of your rules and booking history.
The free tier includes refresh control and basic booking. The tool advertises that it prioritizes local privacy.
Best for: Carriers who want a free refresher and booker and prioritize keeping their data local.
SwiftRelay and FlashRelay
Several smaller refreshers exist (SwiftRelay, FlashRelay, and others) that focus on the core functionality: automatic refresh and straightforward booking. Most are basic and free or low-cost.
Best for: Carriers looking for minimal, affordable tools that do one thing well.
NudoIQ
NudoIQ is a browser extension that runs inside the Relay load board and includes every feature in one monthly subscription: $49.99/month, or 7-day free trial.
Refresh Control: Slider sets the interval from 1 to 5 seconds with built-in jitter.
Three Booking Modes: Alert (pings you on a match), Search (highlights matching loads visually), Autobook (books automatically if your rules match). Set price and lane rules, a profit floor, and a max-books cap.
Lane Intelligence: For each load, NudoIQ shows the 90-day rate history for that lane, a target rate, an expected range, and a confidence level. Example: "$483 target next to a $407 board price." This is decision support, not a guarantee—Amazon rates change based on season, time of day, volume, and other factors.
Net Profit Per Load: Instead of just the posted rate, NudoIQ calculates the dollars you keep after subtracting driver pay, fuel, maintenance, and deadhead to pickup. You see the net profit and net $/mile for every load.
Scorecard Dispute Drafting: NudoIQ reads your Relay scorecard, identifies the violation, and drafts a dispute letter citing Amazon policy. You review, edit, and submit. Amazon makes the final decision.
Backhaul Finder: Search for loads from your current drop-off back toward home within your radius and time window. Sort by total pay, rate per mile, pickup time, or distance home.
Post A Truck Helper: When posting availability, NudoIQ shows origin, destination, distance, and board price alongside your minimums, then posts with one click.
Other Features: HOS overview, driver dispatch by text/email on assignment, Telegram alerts.
Best for: Carriers who want a full-featured refresher, rate history, profit calculation, dispute support, and backhaul finding all in one tool.

How to Choose
If you just need a refresher and basic booking: LoadFetcher's free tier or Rocket Relay's free tier do the job. Neither costs anything.
If you want rate history and profit calculation: NudoIQ includes both. The 7-day free trial lets you test whether the extra features save you time and money.
If you want everything in one place: NudoIQ is built for carriers who also want to dispute scorecards, find backhauls, and post availability—all from the same extension.
If you prioritize privacy and local data: Rocket Relay emphasizes keeping your data on your computer. NudoIQ runs in your browser and doesn't upload your booking rules or history.
All of these tools are independent of Amazon Relay. They're browser extensions published by third parties. Using them doesn't change your account status with Amazon or affect your compliance with Relay's terms.
Testing and Switching
You can install multiple extensions and test them before deciding. Just remember that running two refresher extensions at the same time might cause conflicts. Test one, then another.
If you're currently using one extension and want to test NudoIQ, install NudoIQ, try the 7-day free trial, and see if the extra features (rate history, profit calculation, dispute drafting, backhaul finding) are worth $49.99 a month. Cancel anytime from your Stripe portal if they're not.
What Makes a Good Extension Choice
A good extension for you is one that:
- Automates what you do manually: If you refresh constantly, it should refresh for you. If you struggle to judge rates, it should show you rate history.
- Includes guardrails: Set a profit floor, set a max-books cap, and the tool respects those limits so you don't accidentally book unprofitable work.
- Stays updated: Recent updates mean the developers are actively maintaining it and fixing issues.
- Respects your data: Whether it stores locally or on a server, you should know what happens to your booking preferences and history.
- Fits your budget: Free is good if it does what you need. Paid is worth it if the extra features speed up your decisions or make you money.
Why NudoIQ Stands Out
NudoIQ includes features that other extensions don't advertise: lane rate history, net profit calculation, scorecard dispute drafting, and backhaul finding. These go beyond refresh and booking and address the decisions that cost you time and money.
The extension is rated 5.0 on the Chrome Web Store and used by 300+ carriers. It costs $49.99 a month for every feature, with a 7-day free trial so you can test it without committing.
