I've been selling on Vinted for 7 years and used other extensions before building Bleam. I often get asked about the difference between Clemz and Bleam. Here's an honest, feature-by-feature comparison to help you choose.
I've been selling on Vinted for 7 years with my company. Before creating Bleam, I tested most of the extensions out there, including Clemz. Today people often ask me: "I'm hesitating between Clemz and Bleam, which one should I pick?"
Rather than another marketing comparison, I'll honestly explain what each one does, where the real difference is, and which seller profile it fits. No bullshit, just my take as a reseller who uses these tools daily.
Clemz is kind of the historical pillar of Vinted extensions. They've been around for years and have clearly contributed to building the Vinted automation ecosystem. Comparison below based on Clemz public offering as of April 19, 2026.
Clemz lets you repost your items, send messages to users who favorited your items, exchange views/favorites with other sellers, bulk-edit listings, and track your sales. It's solid and if you're starting out on Vinted, it's a perfectly decent tool.
But as a high-volume reseller, I eventually hit the limits. Listing templates, hourly automatic backup, a conversational Intelligent Assistant — those were features I wanted and that the tools back then didn't offer.
I figured: if it doesn't work for me, there are probably plenty of resellers in the same situation. With a dev background, I jumped in. My cofounder and I built Bleam starting from our real reseller needs — not a theoretical spec sheet.
The result: every Bleam feature is pushed to the max, because we use the extension ourselves daily on our own accounts. When something bothers us, we fix it. That's the difference you'll see in the comparison below.
Bleam is built by Vinted resellers, for Vinted resellers. Every feature exists because we needed it ourselves to sell more efficiently.
Here's the match, feature by feature. For each one, I'll tell you what Clemz does and what Bleam does. That's where you'll see the real difference.
Clemz lets you send an automatic message with a discount to users who favorite your items. The message is the same for everyone, no variation based on the buyer.
With Bleam, you can personalize the message with the buyer's first name, and more importantly send different messages based on time of day, day of the week, or item price. A buyer who likes a €10 item Monday morning won't get the same message as a buyer who likes an €80 item Saturday night.
Clemz doesn't offer any listing template system.
With Bleam, you create reusable listing templates. When you have several similar items to post (same brand, category, size), you apply the template in one click and the listing fills itself. For resellers who post a lot, it's a massive time saver. Honestly, this was THE feature I missed most before building Bleam.
Clemz lets you repost your items to boost them in the Vinted algorithm. It's their historical feature and it works.
Bleam does the same, with more flexibility. Repost your whole closet in one click, or schedule reposts in advance (great to auto-repost over a weekend when you're away). Options for price change during repost (fixed, percentage, amount) and AI rewriting of title/description so each repost stays unique.
Clemz lets you download labels, but ordering stays on your end.
With Bleam, as soon as a sale is confirmed, the label is ordered automatically. Nothing to fetch, everything happens in the background. Auto-resizing for 4x6 thermal printers included. Add automatic post-sale messages (thanks after payment, review request after finalization) and your customer relationship runs itself.
Clemz offers a backup system, but it's manual: you have to trigger it every time.
With Bleam, every listing in your closet is backed up automatically every hour (title, photos, description, brand, size, price, colors, category, full attributes). Huge benefit: if your Vinted account gets restricted or banned, you can restore your entire catalog on a new account in minutes. Real safety net, and imo it's non-negotiable when you live off reselling.
Clemz supports multi-account Vinted. Refer to their public pricing for per-plan specifics.
With Bleam, from our higher plans you can connect multiple Vinted accounts on a single subscription. Everything managed from one dashboard, every automation runs in parallel on each account. For resellers with 2, 3, 5+ accounts, it's a real time saver.
Clemz has no AI assistant to negotiate or reply for you.
With Bleam, you can enable an Intelligent Assistant that negotiates prices based on your set margins and automatically replies to buyer questions. It runs 24/7: while you sleep, while you work, while you're doing anything else, it sells for you. You keep full control of the rules (margins, counter-offers, acceptance message, floor price).
Clemz requires your browser to be open to run.
With Bleam Cloud, your extension runs on a dedicated server managed by us. Even when your computer is off, Bleam keeps replying, reposting, sending favorite messages and negotiating. For real pro resellers, it's a game changer.

Start with BleamIf you're unsure, just start your free trial of Bleam. It's free, with no commitment whatsoever, and cancellable in one click anytime. Honestly, I think you'll see the difference within the day — especially on listing templates and message personalization.
Start with BleamHonestly, both tools aren't aimed at the exact same profile. Here's my simple rule, based on what you do per month.
Beginner or casual seller (under €1,000/month)
If you're starting out or selling casually, Clemz does the job just fine: reposting, favorite messages, bulk edits, basic sales tracking. A historical, stable tool covering the fundamentals without overcomplicating things. Bleam is accessible from day one too, but a chunk of its value (templates, Intelligent Assistant, Bleam Cloud, automatic backup) really shows up once your volume grows.
Regular seller doing more than €1,000/month and looking to scale
This is where Bleam truly shines. Intelligent Assistant negotiating and replying to buyers 24/7, listing templates speeding up publications, hourly automatic backup, labels ordered automatically. At that volume, every unhandled hour represents potentially lost sales.
Pro reseller with multiple Vinted accounts
At this level, Bleam is clearly the right fit. Multi-account on a single subscription, Bleam Cloud to run the extension 24/7 with your PC off, and the Intelligent Assistant multiplying sales on each account in parallel. The gains massively outweigh the subscription cost.
Both work for beginners. The real difference: Bleam includes from day one features Clemz doesn't have (listing templates, automatic backup, labels ordered automatically). For someone starting out who wants to save time right away, Bleam is more direct.
Technically yes, but honestly there's no point. You'll duplicate actions (two sets of favorite messages for instance) and stacking two automation tools on the same account increases the risk that Vinted detects unusual behavior. Pick one tool.
Yes, several. Listing templates (to post your items in 30 seconds), automatic backup of all your listings every hour, labels automatically ordered the moment a sale happens, the Intelligent Assistant that negotiates and replies to buyers, Bleam Cloud to run the extension 24/7 with your computer off, and multi-account Vinted on a single subscription.
No, it's available from our higher plans. You'll find the full details on the pricing page. If you only want templates, labels, reposting and favorite messages, the entry plan is enough.
Yes, from our higher plans. Link your Vinted accounts to your Bleam account and every automation runs in parallel on each one, with a single subscription.
5 to 10 minutes. Install the extension, connect your Vinted account, set your preferences (favorite messages, negotiation margins if you enable the Assistant), and you're good. The UI is designed to take 2 minutes, not 2 hours.
Bleam automates actions you could perform manually and is designed to respect Vinted's typical usage rates. Over 2,000 professional sellers use Bleam daily. As with any third-party automation tool, use remains at your discretion and under your own responsibility regarding Vinted's terms of service.
The trial is free, with no commitment whatsoever, and cancellable in one click anytime. Honestly, I think you'll see the difference within the day — especially with listing templates and message personalization.
