Best Amazon Relay Autobookers in 2026, Compared
The largest Amazon Relay autobooker with a published user count in 2026 is Rocket Relay, with roughly 9,000 users and a 4.1-star rating on the Chrome Web Store; the most-installed Relay tool overall is LoadFetcher, at about 20,000 users, though it does not offer auto-booking (its listing sells refresh and analytics features only); and which tool is actually best for you depends on your fleet size, your region, and how much unattended automation you want. This article compares eight tools worth shortlisting as of July 2026.
One thing before the numbers: we build one of the tools on this list, Relay Autobooker Cardamon. Where a competitor is stronger, we say so plainly — Rocket Relay has nine times our install base, and LoadFetcher carries a higher store rating than we do. Every rating, user count, and price below comes from our July 2026 research and can change.
How this comparison works
We found more than 15 live or recent Chrome extensions that refresh or auto-book the Amazon Relay load board, plus custom bot builders and off-store sellers. Churn in this niche is high. Superfly was last updated in April 2022 and its rating has decayed to 3.1; Gill Auto Booker was removed from the Chrome Web Store entirely. This comparison covers eight of them — the tools with real traction or a distinct offer — and skips refresher-only tools, micro-vendors, and listings that have gone stale or been delisted.
For each one we checked the Chrome Web Store listing (rating, user count, last update), the published pricing, the trial and refund terms, and what the tool does that the others don't. Where a vendor publishes no numbers, we say "not published" rather than guessing.

Tool by tool
Rocket Relay
Rocket Relay is the autobooker category leader: about 9,000 users and 4.1 stars across 63 ratings, with the extension updated as recently as July 30, 2026. The free tier is genuinely useful — auto-refresh, alerts, and one-click FastBook on matched trips, no card required. Pro is $49 per month after a 7-day trial and adds automatic booking, 15+ stackable filters, location targeting, and bulk Post-a-Truck management.
Two more things stand out. It runs on Chrome, Edge, and Brave on desktop plus Android browsers (Lemur, Quetta), covering the US, Canada, UK, EU, Germany, Spain, Poland, India, and Japan. And its privacy stance is the strongest in the niche: the site states that your loads, trips, and drivers stay local in your browser and never reach the vendor's servers.
What to watch: the site shows booking receipts rather than named testimonials, and there is no refund commitment beyond "cancel anytime". Who it fits: most carriers. It is the sensible default, and its free tier is the lowest-risk way to try this category at all.
LoadFetcher
LoadFetcher has the biggest install base of any Relay tool — about 20,000 users and a 5.0 rating (from 11 ratings) on its Chrome Web Store listing, updated July 23, 2026. The catch: it does not sell auto-booking — its listing and marketing cover refresh, analytics, and alerts only. It offers auto-refresh, price-per-mile history, trip tracking with ETAs, Telegram and browser notifications, truck posting management, route visualization, and road-restriction and facility alerts.
What to watch: pricing is not published — the listing shows in-app purchases — and the marketing site renders almost nothing to crawlers, so plan to evaluate it through the store listing and its YouTube demos. Who it fits: dispatchers who want to see loads sooner and track earnings, but intend to keep pressing Book themselves. If you want the actual booking automated, it is not the tool for that job.
SwiftRelay
SwiftRelay holds 4.5 stars across 56 ratings — the second-highest review count in the niche after Rocket Relay — with around 1,000 users. Its three tiers are built around device counts for dispatch teams: Lite (2 devices, refresh and highlights), Pro (5 devices, auto-booking and advanced filters), and Enterprise (10 devices plus a VM and a "Speed Optimizer"). Its testimonials repeatedly credit the team with keeping pace with Amazon Relay UI updates.
What to watch: as of July 2026, the pricing page shows "Payment options loading…" and the dollar amounts never rendered in our checks, so verify the cost with the vendor before committing; the return policy states all sales are final; and the 7-day trial is one per carrier, not per user. The extension's last listed update was June 15, 2025.
Who it fits: dispatch teams that need several seats and are willing to install first and confirm pricing afterward.
JungleBark
JungleBark is the filtering-depth pick. Beyond refresh and auto-book, it also sells a standalone "Legend" load-board app (a separate tier, from $399.95/mo) that replicates the Relay board in a cleaner UI, and it filters things the native board can't: containers, third-party loads, recovery loads, empty-trailer-only booking, specific facility codes, and skipped origins, destinations, or facilities.
Pricing is published clearly: Basic at $49.95/month or $449.95/year, Pro at $99.95/month or $899.95/year. It is one of only two tools here with public annual plans (ours is the other). The site claims 1,000+ clients and 174,000+ lifetime booked trips, with eight named testimonials, and the 7-day trial requires no card.
What to watch: no public Chrome Web Store rating or user count surfaced in our research, and the site publishes no refund policy. Who it fits: dispatchers who live in filters and want the annual price break.
Flash Relay
Flash Relay is the premium-priced outlier, listed at $149/month as of July 2026 — roughly three times the market's $49 cluster — with a 25% discount promoted on its site. It sells 24/7 unattended booking, multi-tab simultaneous booking, Telegram notifications, and multi-stop optimization, covering the US, UK, EU, Canada, and India. Its store rating is high at 4.8 stars (21 ratings), though from a small base of 374 users.
What to watch: the Chrome Web Store listing shows the extension was last updated December 3, 2024 — the oldest last-update date we could verify among the tools in this comparison, in a niche where several rivals shipped updates in June and July 2026. The site carries no testimonials, and its claim that it "avoids Amazon detection" is the most explicit anti-detection marketing among the tools in this comparison, which says something about the risk everyone here is managing.
Who it fits: honestly, it is hard to recommend paying triple the going rate for a build that old. Ask the vendor about update plans before subscribing.
Amazing Relay
Amazing Relay has the sharpest audience focus in the niche: built by an active Amazon Relay driver for small carriers and self-dispatchers running 1–3 trucks, with a touch-friendly interface for working from the cab and messaging about staying within Amazon's rate limits rather than dodging detection. It also offers the longest trial here — 10 days of full functionality.
The pricing is unusual: Basic is a $49 one-time payment and then free ongoing (core filtering and monitoring), Standard is $99/month for the fastest refresh and unlimited daily autobooks, and an Ultimate tier at $249/month is listed as "coming soon". It is US-focused.
What to watch: we found no Chrome Web Store listing, ratings, or user counts — the site offers a founder story and team photos in place of third-party proof. Who it fits: US owner-operators who want the in-cab design and the 10-day trial, and don't mind being an early reference.
RGD AutoBooker
RGD AutoBooker (Rolling Global Digital) is the only tool we found that automates Relay's contract board, not just spot loads: the Business tier at $249/month adds "LoadBoard & Contracts" support and "Lightning Auto Book", while Essential at $79/month covers auto-booking, notifications, and refresh controls. The founders present themselves as daily Relay users rather than pure software people.
What to watch: the site publishes no reviews or testimonials and no refund policy — all sales are final; the trial says "Start Free Today" with no stated length; and no Chrome Web Store listing is linked anywhere on the site. Its own FAQ describes Amazon sending "multiple warning emails" before short bans while also claiming a "0% ban rate" — read that page before buying.
Who it fits: fleets that specifically need short-term contract automation, which nobody else sells, and are comfortable purchasing without third-party reviews or a refund path.
Relay Autobooker Cardamon (ours)
Relay Autobooker Cardamon is our extension, so weigh this section accordingly. Two things in it are uncommon. Relay Assistant auto-negotiation handles rate requests automatically — no other tool in this comparison markets negotiation automation (there is a separate guide to how Relay Assistant works). And it publishes the broadest region list here: 14 Amazon Relay regions, including Mexico, Brazil, and Australia, which no other published list in this comparison covers.
The Smart Refresher tier is free forever, with no subscription required. Premium is $49.99/month or $499/year — about two months free on annual — with a 7-day trial, and it books with selectable strategies (Regular, Fast, Super Fast), Stem Time and Max Stops filters, payout monitoring with "What changed?" and "Skipped" chips, "Slow down on errors" throttling, Ctrl+Space Fast Confirm, and multi-tab support. It works on Chrome for Windows and macOS and on Android via Kiwi Browser, and it links a visible refund policy directly under its pricing — SwiftRelay and RGD state all sales are final, Flash Relay links a refund policy page, and the rest say nothing.
The honest downside: we have roughly 1,000 users and 4.0 stars from 25 ratings as of July 2026. That is about a ninth of Rocket Relay's install base and far fewer reviews than SwiftRelay's 56. If a long public review trail is what convinces you, Rocket Relay has the deeper one.
How to choose
Match the tool to how you run, not to whoever shouts loudest. We keep a longer checklist in our FAQ on how to choose an Amazon Relay autobooker, but the short version:
- Owner-operator, 1–3 trucks. Amazing Relay is built for exactly this and gives you 10 days to test. Our tool targets the same audience, with Android support via Kiwi Browser for running from the cab. Rocket Relay's free tier is the cheapest way to learn whether automation helps your lanes at all.
- Dispatcher or small fleet. SwiftRelay's device-count tiers fit multi-seat teams — confirm the price before subscribing — the amounts did not render in our July 2026 checks of the pricing page. JungleBark Pro adds the deepest filters and a cleaner board UI. RGD Business is the only option if contract-board automation is the job.
- Free-first or tight budget. LoadFetcher's free refresher and analytics, Rocket Relay's free tier, and our free Smart Refresher all cost nothing and need no card. Run one on your own board for a week before paying anyone — you can install ours here.
- EU, UK, or other non-US boards. Rocket Relay lists the US, Canada, UK, EU, Germany, Spain, Poland, India, and Japan. Flash Relay lists the US, UK, EU, Canada, and India. We list 14 regions, and ours is the only published list that includes Mexico, Brazil, and Australia. Amazing Relay is US-focused.
One caution before you pay for anything: an autobooker cannot create freight that isn't on your board. If loads are thin to begin with, read our guide on why you can't find loads on Amazon Relay first — filters and timing usually matter more than raw booking speed.
The part every vendor downplays: account risk
Amazon has never published a Relay-specific policy on autobookers, but its general Conditions of Use prohibit accessing Amazon services with "any robot, spider, scraper, or other automated means". There is a documented consumer-law case in which Amazon told a Relay carrier it had "used bots or certain software to get loads off the loadboard", and TruckersReport threads document sudden suspensions for unexplained "irregularities".
The vendors' own marketing confirms the tension. Flash Relay advertises avoiding detection, RGD claims a "0% ban rate" while its FAQ describes Amazon's warning emails, and enforcement reaches the store level too: Gill Auto Booker was removed from the Chrome Web Store and survives only as sideloadable archives.
So here is the plain statement, and it applies to our product as much as anyone else's: any of these tools automates account activity that Amazon's carrier terms of service don't explicitly authorize. Weigh that against the loads you're losing to whoever books faster, and decide with both facts on the table. Our full position is here: is it safe to use an autobooker with Amazon Relay?
