Launched a free Chrome extension for classified-ad sellers — now stuck on the hardest part: getting the first real users

Hey everyone,

Wanted to share where I'm at and get some honest input from people who've been through this.

I built a Chrome extension for people who sell on Kleinanzeigen (Germany's biggest classifieds platform). The problem it solves: ads sink down the search results over time, so sellers manually re-post them to get back to the top. My tool does that in one click — it carries over the title, description, price, and photos automatically. It's live and free, and I use it daily for my own ads.

The build was the easy part. Getting users is the real challenge — and where I'd love advice.

What I've tried so far:

  • Direct outreach to high-volume sellers (bike shops, clothing resellers). A couple replied, most didn't. One business was interested but went quiet.
  • I've got a landing page and just started posting in maker/beta communities.

Where I'm stuck / questions for you:

  • For a niche tool tied to a specific platform, what actually worked for you to get your first 10-20 real users?
  • Direct outreach feels slow and hit-or-miss — is that just the reality early on, or am I missing a better channel?
  • How did you figure out if people would pay before building payment infrastructure?

I know the honest answer is often "it depends," but I'd genuinely value hearing how others cracked the cold-start problem for a niche product.

Happy to share the tool with anyone curious — just ask in the comments.

Thanks 🙏

[Feedback] Free Chrome extension for Kleinanzeigen sellers (Germany) — re-post your ads to the top in one click. Looking for testers, especially German sellers!

Hey everyone,

I built AnzeigenBoost, a free Chrome extension for people who sell on Kleinanzeigen.de — Germany's biggest classifieds platform (like Craigslist / Facebook Marketplace).

👉 If you sell on Kleinanzeigen, this is for you — I'd love your feedback!

The problem: on Kleinanzeigen, your ads slowly sink down the search results over time and stop getting seen. Sellers have to manually delete and re-create their ads to get back to the top — tedious if you have lots of listings.

What it does: AnzeigenBoost re-posts your existing ad in one click — title, description, price, category, and photos are all carried over, so your listing jumps back to the top with zero copy-pasting. It also has AI helpers: generate ad text from a photo, reply templates, photo feedback, and price suggestions.

It's completely free, no subscription. I use it myself daily for my own Kleinanzeigen ads and it genuinely saves me time.

I'm especially looking for German Kleinanzeigen sellers to test it and tell me honestly:

  • Is the one-click re-posting clear and smooth?
  • Anything confusing or broken?
  • What would make it more useful for you?

(Any general UX / first-impression feedback is welcome too, even if you don't use Kleinanzeigen.)

Deutschsprachige Verkäufer: Falls du auf Kleinanzeigen verkaufst und Lust hast, es zu testen — ich freue mich riesig über ehrliches Feedback! 🙏

Thanks!

Built a Chrome extension to boost Kleinanzeigen ads with one click + AI

Hey everyone, I wanted to share a side project I've been working on to solve a personal frustration: spending way too much time manually tweaking listings on Kleinanzeigen.de.

I built a Chrome extension called AnzeigenBoost that uses AI to automatically optimize ad titles, descriptions, and pricing with a single click. The goal is to save time and help listings get more views and sell faster.

It's currently in a private beta phase (unlisted on the Chrome Web Store) and I'm looking for people who use Kleinanzeigen to try it out and provide honest, constructive feedback on what works and what's confusing. In return, testers will have direct influence on what I build next.

You can install it directly here:

Any feedback on the concept, usability, or features you'd like to see would be greatly appreciated.

Muss man bei Kleinanzeigen wirklich immer wieder für Boosten bezahlen?

Ich verkaufe auf Kleinanzeigen. Aber ich finde kaum noch Käufer.

Dann sagt die App: "Boosten" für mehr Sichtbarkeit. Also zahle ich.

Aber ich muss immer wieder bezahlen. Einmal reicht nicht. Erst nach 2-3 mal Boosten kommt vielleicht ein Käufer.

Das frisst meine ganze Marge. Ich bin es leid.

Geht das nur mir so? Oder kennt ihr das auch?
