Judge an Amazon Relay autobooker on seven points: whether it runs locally in your browser or hands your Relay login to a cloud service, human-like timing options, adjustable booking speed, filters for payout, stops, and stem time, support for your Relay region, a free tier or trial, and reachable support backed by an active changelog.

Does it run in your browser or in the cloud?

Check this first. A tool that runs in the cloud logs in to Relay from its own servers, which means typing your Amazon Relay email and password into someone else's system. A browser extension runs on your own computer: you log in to Relay yourself, and the tool works on the load board page already open on your screen. Relay Autobooker Cardamon is a Chrome extension that runs locally in your browser. It never asks for your Relay credentials, so they stay with you.

Does it have human-like behavior options?

A tool that hits the load board at an exact fixed interval produces a pattern no human would. Look for randomized timing, scheduled pauses, and automatic backoff when the board returns errors. The extension has all three:

• Imitate a human's behavior: varies the refresh timing instead of repeating the same gap
• Add a delay every X refreshes: pauses 10 to 15 seconds after a refresh count you pick, the way a person steps away from the screen
• Slow down on errors: doubles the wait when Amazon rate-limits, up to 30 seconds, then resets after a successful request

Can you choose the booking speed?

The fastest setting wins more contested loads but leaves less margin for error, so you want a tool that lets you set the pace. The extension offers three booking strategies: Regular at about 1000 ms between actions (the most stable), Fast at about 300 ms, and Super Fast at about 100 to 150 ms. A Ctrl+Space shortcut also triggers the topmost confirm button when you are watching the board yourself.

What filters should an autobooker have?

Auto-booking without filters fills your calendar with cheap loads. Three filters do most of the work: a minimum payout, a stop-count cap, and a lead-time minimum so the tool skips a load that picks up in 40 minutes from 150 miles away. Relay Autobooker includes payout filters, Max Stops, and a Stem Time filter, plus "Skipped:" chips that name which filter blocked a load, so you can tune your settings instead of guessing.

Does it support your Relay region?

If you book on relay.amazon.ca or relay.amazon.co.uk rather than the US board, confirm the tool runs on your domain before paying. The extension works across 9 Amazon Relay regions: the US, Canada, the UK, France, Italy, Germany, India, Japan, and Spain.

Is there a free tier or trial?

Run any autobooker on your own account before paying for it. The free Smart Refresher tier costs nothing and has no time limit: it auto-refreshes the board with human-like timing while you book by hand. Premium adds automatic booking and confirmation and starts with a 7-day free trial. After that it costs $49.99 per month or $499 per year, and you can cancel anytime.

Can you reach support, and is the tool maintained?

Amazon changes the Relay load board layout without warning, and an abandoned tool can break the same week. Check for a support address that answers and a changelog with recent, dated releases. Cardamon has been in development since 2020, the current version is 11.12, and the changes history lists each release with its date. Version 11.10, for example, repaired the Relay Assistant after Amazon changed the load board UI. Support runs through support@cardamon.org.
