Priya Nadar Developer relations November 4, 2026 11 min read > **What is Stellar AIO?** Stellar AIO is a desktop checkout bot for Windows and macOS, made by Stellar Automation LLC, that monitors more than 100 retailers, including Amazon, Best Buy and Target, and tries to check out when stock appears. You store proxies in named proxy groups on its Proxies tab, then pick a group inside each task. A clean **Stellar AIO proxy setup** comes down to three decisions: which proxy type goes into which group, how many IPs each task gets, and which group you select in each proxy field of a task. Get them wrong and good accounts burn on login loops before the restock starts. This guide follows the current Stellar AIO 4.0 guides at guides.stellaraio.com. It covers adding proxy groups, the format Stellar accepts, how to split ISP and residential IPs across monitor, login and checkout traffic, and what the common proxy errors on Amazon and Best Buy mean. Wherever Stellar's own advice differs from general habit, we go with Stellar's advice. ## What does Stellar AIO support right now? Stellar lists 100+ retailers across the United States, Canada, the United Kingdom and Europe, with retailer guides for Amazon, Best Buy, Target, Walmart, Newegg, GameStop, Costco, Apple, B&H Photo and many more. Amazon also covers Australia, Mexico and Japan. The app runs on Windows 10, Windows 11, Windows Server 2016 or later, and macOS 14 or later. Support is per retailer and per regional site, not per country. Best Buy US and Best Buy Canada are separate modules with separate guides, and a SKU or account from one won't carry over to the other. Stellar also ships a mobile companion app for iOS and Android that can edit the proxy groups on your connected computer. For reference, Stellar's site lists two plans at the time of writing: $899 for the first year, then $599 a year, or $499 for the first three months, then $150 every three months. Check stellaraio.com before you buy, because bot pricing changes often. ## How do you add proxies in Stellar AIO? Open **Proxies** in the sidebar, click **+** next to **PROXY GROUPS**, name the group and click **Add**. Select the group, open **Manage Proxies**, paste one proxy per line into **Proxy list** and click **Save**. Then test the group against your target retailer and select it in your tasks. ### Step 1. Create one group per job Build groups around what the proxies do, not only who sold them. A setup that holds up well looks something like "Amazon Login ISP", "Amazon Monitor ISP", "BBY Monitor ISP" and "BBY Checkout Resi". When something breaks mid-drop, you know which pool to look at. ### Step 2. Paste and save, carefully The key detail in Stellar's docs: **saving replaces the group's whole list with what is in the box.** Manage Proxies does not append. To add 20 IPs to a group of 50, keep the 50 existing lines in the box and paste the new 20 underneath. Delete a line, save, and that proxy is gone from the group. Keep a private copy of your provider's original list so you can restore it. The mobile app works differently. Under More, then Proxies, you choose **Append** to add lines or **Replace** to overwrite the group. Read the prompt before you tap. ### Step 3. Pick the group inside the task In the Tasks tab, each mode shows its own proxy fields. Best Buy monitor modes use **Monitor Proxy**, while Shipping, Pickup, Invite, Reset and Account-Gen use **Checkout Proxy**. Saved Best Buy and Amazon accounts also have a **Login Proxy** field. Each of these can point at a different group, and on both retailers they should. ### The proxy format Stellar accepts Stellar documents a single format: `IP:PORT:USERNAME:PASSWORD`, one complete entry per line. All four parts are required. A list that looks like this is ready to paste: `192.0.2.10:8000:user_a:pass_a 192.0.2.11:8000:user_b:pass_b` Those are documentation addresses, so don't expect them to connect. Loopway delivers proxies in the dashboard as `host:port:user:pass` lines, the same four-part order, so you can copy a static ISP list straight into Manage Proxies. If a provider gives you `user:pass@host:port` or a URL with `http://` in front, reorder it into the four-part form before saving. ## Which proxy type should you use for each site? Use static ISP proxies for Amazon login, Amazon checkout and Best Buy monitoring, because those flows reward a stable IP. For Best Buy checkout tasks, Stellar's current guide recommends high-quality residential proxies, and notes that tested ISP proxies may work on a given release. Keep monitor traffic on its own pool so it never slows checkout. ### Amazon Stellar's Amazon guide is clear here. Clean, stable ISP proxies are the starting point, and every Amazon account should get one dedicated ISP login proxy that stays with it. The guide warns against sharing one login IP across many accounts, rotating an account's login IP, or signing into one account from several locations at once, all of which can trigger reauthentication or account restrictions. It also notes that continuous monitoring can use a lot of residential data and that rotating residential IPs make sessions less stable. So for Amazon, run a static ISP group for login and checkout, plus a separate ISP group for Monitor tasks. Stellar says clean datacenter proxies may also work, but proxy quality matters more than task count. A dedicated [retail ISP proxy from Loopway](https://loopway.io/retail-proxies) keeps one IP for the whole term, which is exactly the pairing Stellar asks for. ### Best Buy Best Buy splits into two jobs. For the **monitor**, monitor-zip and monitor-stores modes, Stellar recommends clean ISP proxies. For the **Login Proxy** on a saved account, it recommends a stable ISP proxy so the account signs in from a consistent address. For the **Checkout Proxy** on Shipping and Pickup tasks, the current recommendation is high-quality residential, with the note that tested ISP checkout proxies may work for a particular release. In practice that means three groups: ISP for monitoring, ISP for account logins, and a residential group for checkout that you can swap for tested ISP when a release allows it. Stellar's Best Buy guide also describes a "Fetch Akamai" status as the task processing data required by Best Buy's protection, and advises about two minutes before treating it as stuck. ### Monitor tasks on other retailers Stellar's general proxy guide puts it simply: ISP proxies suit monitoring and consistent connections, residential can suit checkout or queues, and the retailer guide wins whenever it says something different. Rotating residential is billed per gigabyte, so a monitor polling every few seconds on rotating IPs drains data fast. Keep long-running monitors on static ISP unless the retailer guide says otherwise. ## How many proxies do you need per task? Stellar recommends at least a 1:1 proxy-to-task ratio as a starting point, so 25 proxies for 25 tasks, with 2:1 giving you spare IPs to rotate in. Count every task that shares the same proxies across all groups. Copying 25 entries into two groups still gives you 25 proxies, not 50. The retailer guides add tighter limits on top of the general ratio: - **Best Buy:** no more than one checkout task per SKU, account and fulfillment method. One monitor per SKU is enough for most setups. Duplicate Shipping tasks on one account can cause login conflicts and account locks. - **Amazon:** one stable ISP login proxy per account, 1 to 3 Monitor tasks per SKU as a starting point, one Special task per account, and about 20 Fast tasks at most per Stellar instance, with one Fast task per account. - **Scaling:** start small, watch the statuses, and add tasks only when the proxies keep up. Stellar says plainly that more tasks don't automatically mean better results. If you're sizing a static ISP order for a release weekend, short terms keep costs down. Loopway sells Retail ISP from $1.08 per IP for one day, and our [guide to daily ISP proxies](https://loopway.io/blog/daily-isp-proxies) explains when a 1-day term makes more sense than a month. ## Testing your proxies before a drop Stellar's Proxies tab has a built-in tester. Select the group, choose a destination in **Select/Enter URL** (Amazon, Target and Walmart are in the list, or type your own URL), then click **Test All**. The summary shows Total proxies, Working, Failed and Untested, and you can click **Stop** partway through. Three habits make the results useful: 1. **Test against the retailer you'll actually run.** A proxy that passes on one site can fail on another. Stellar says this directly. 2. **Retest failures in small batches.** Testing hundreds of proxies at once skews response times. Retest the failed lines on their own before deleting anything. 3. **Treat a pass as connectivity only.** A Working result means the proxy connected at that moment. It does not promise a checkout, and one failed test doesn't mean the IP is dead for good. For a second opinion outside the bot, paste a few lines into the [Loopway proxy checker](https://loopway.io/tools/proxy-checker) to confirm that the credentials authenticate and to see where the IP geolocates. That separates a provider problem from a retailer block. ## Common Stellar proxy errors and fixes These come from the error sections of Stellar's Amazon, Best Buy and Proxies guides. Restart only the affected task, not the whole setup, because a mass restart throws away queue and session progress. - **Login Detected Proxy Ban (Best Buy):** stop the task, replace the blocked proxy with a tested one and retry. If the entire pool fails, try a different pool or provider instead of cycling the same blocked addresses. - **CSRF token error (Amazon):** check the Monitor proxy group, replace blocked proxies, raise Monitoring Delay and restart only the affected monitors. - **401 error or repeated login (Amazon):** clear the account's cookies, check the password, Authenticator Key, region and Login Proxy, then rerun. Avoid simultaneous logins through changing IPs. - **Captcha detected or rotating proxy (Amazon):** try a clean proxy, increase the delay and cut unnecessary traffic. - **All tests fail:** compare each entry with your provider's dashboard, confirm the plan hasn't expired and, on data plans, that you still have data left. - **Proxies saved but tasks still error:** open the task and check which group is selected. This is the most common beginner mistake in Stellar's own guide. Stellar's Best Buy OTP Input can pull email codes through AYCD. If you run AYCD's tools too, our [AYCD proxies guide](https://loopway.io/blog/aycd-proxies-guide) covers their proxy side. ## Key Takeaways - Stellar uses named proxy groups. Create them in the Proxies tab and select them in each task's Monitor, Checkout or Login proxy field. - Manage Proxies replaces the whole list on save, so paste new lines under the existing ones. - The only documented format is IP:PORT:USERNAME:PASSWORD, one per line. - Amazon wants stable ISP proxies with one dedicated login IP per account. Best Buy wants ISP for monitoring and logins, with residential as the current checkout recommendation. - Start at 1:1 proxies to tasks, count shared proxies once, and follow each retailer's per-account task limits. - Test against the retailer you'll run, and restart only the task that's failing. ## FAQ **Where are proxies in Stellar AIO 4.0?** In the Proxies tab in the left sidebar. You create a group with the + next to PROXY GROUPS, then add proxies through Manage Proxies. The mobile companion app can also edit the groups on your connected computer. **Does Stellar rotate proxies inside a group?** Stellar's guide says ratios like 2:1 do not mean each task cycles through a fixed pair of proxies, and it doesn't document the exact assignment logic. Plan for at least one proxy per task and keep spare IPs in the group. **Can I use the same proxy group for monitors and checkout?** You can, but Stellar advises against loading monitor, login and checkout traffic onto one small pool, especially on Amazon. Separate groups make it easier to find the pool that's blocked. **Are datacenter proxies OK for Stellar?** Stellar says clean datacenter proxies may work on Amazon and that some retailers restrict them more heavily. Use them only where the retailer guide indicates they're suitable. **Why does my proxy pass the test but fail in tasks?** The test checks connectivity to one destination at one moment. The task might use a different proxy field, the retailer might block that IP during a release, or the account itself might need a fresh login. **How much residential data does Stellar use?** Stellar doesn't publish a figure, because usage depends on the site, mode, retries and run time. Watch your provider's dashboard during the first run and keep monitors off rotating residential where you can. That's a complete Stellar AIO proxy setup: separate groups for each job, the right type in each field, and testing against the store you'll actually run. If you need dedicated static ISP IPs for Amazon logins or Best Buy monitors, Loopway sells them by the day with country targeting, and the same setup logic carries over if you also run Refract, as covered in our [Refract bot proxy setup guide](https://loopway.io/blog/refract-bot-proxy-setup). ## Keep reading Guides Nov 4, 2026 11 min read ### [Refract Bot Proxy Setup for Target and Best Buy](https://loopway.io/blog/refract-bot-proxy-setup) Refract bot proxy setup for Target and Best Buy: add proxy lists, split ISP monitors from residential tasks, plan IPs per task and fix proxy errors.
