Osclass vs Yclas vs Flynax vs Sharetribe: An Honest Comparison
A founder's head-to-head of the four classifieds/marketplace scripts people actually evaluate, written by someone who builds one of them (Yclas). Yes, really. Here's what each is good for, where each leaks, and the gap none of them fills.
Let's get the conflict of interest out of the way first. I build classifieds software for a living. I run Yclas. So I have skin in this game, and you should read everything below with that in mind.
The four contenders, in one table
| Osclass | Yclas | Flynax | Sharetribe | |
|---|---|---|---|---|
| Model | Open-source PHP script | Hosted SaaS | Self-hosted PHP, one-time license | Hosted SaaS |
| License cost | Free core | Free / $29–89/mo | $95–195 one-time | $39–299/mo (annual) |
| Hosting | You host it | Hosted for you | You host it | Hosted for you |
| Checkout/payments | Optional, not forced | Optional, not forced | Optional, not forced | Core to the architecture |
| Custom fields | Yes, capable | Yes | Yes, per-niche packages | Limited |
| Modern UX feel | Dated | Modern | Dated | Modern |
| Best for | Tinkerers with hosting | Founders who want hosted + control | Budget self-hosters with a niche in mind | Transactional marketplaces |
Osclass: the capable open-source warhorse
Osclass is free, open-source PHP. You download it, you host it, you extend it with plugins and themes. The core is genuinely stable, it's been running real classifieds for over a decade.
- What it's good at: Being free, being yours, running classifieds at scale without license fees. The plugin ecosystem, while fragmented, covers most of what a listings site needs.
- Where it leaks (and I'll be blunt): It looks its age.The default UX feels like 2009, and no amount of theming fully hides it. The ecosystem is fragmented, plugins from different authors conflict, and someone still runs backups and patches plugins. You're the sysadmin.
- Who it's for: Someone technical who wants full control, pays nothing for the core, and is willing to invest in modernizing the frontend. Not for a non-technical founder who wants to launch in a weekend.
Yclas: hosted classifieds, no checkout by default
Yclas is the hosted SaaS I run. No checkout, no transaction cut. Cloud-hosted, nothing to install. The free tier has no listing or member caps, with a Yclas Neo badge in your footer. Your own domain and badge removal is $29/month (Go). Priority support is $89/month (Zen).
- What it's good at: No-checkout is the default, not a fight. Real custom fields with search filters for any niche, buyers contact sellers through a form on the listing page that opens a retained on-site thread with email notifications, and Open Graph tags so shared listings preview with photo and price on Facebook. Run it alongside an existing forum or site on a separate subdomain.
- Where it leaks:No automated import — listings are created one at a time. No sitemap or structured data for Google yet. Export is manual, within 2 business days. It's a new product and features are still shipping.
- Who it's for: A founder or community operator who wants hosted classifieds without payment-processing baggage, and is fine running it alongside whatever they currently use for dues and events.
Flynax: the budget self-hosted niche player
Flynax sells self-hosted PHP classifieds as a one-time license ($95–195), with niche-specific packages (auto, real estate, pets, etc.). It explicitly markets itself as an Osclass alternative.
- What it's good at: A one-time fee instead of recurring SaaS, niche-tuned packages, full code ownership, capable feature set.
- Where it leaks: Self-hosted PHP means you own hosting, updates, and security. The admin UI is dated, release cadence is slow, and customization often means digging into the code.
- Who it's for: A budget-conscious operator with a specific niche, their own hosting, and tolerance for a dated interface in exchange for no recurring fees.
Sharetribe: the modern one, built for the wrong customer
Sharetribe is the polished, hosted SaaS everyone evaluates first. Build is $39/mo (test mode only), Lite $99/mo (live, subdomain), Pro $199/mo (custom domain), Extend $299/mo (API).
- What it's good at:Being genuinely modern, mature, well-documented, with a real ecosystem. If you're building a transactional marketplace (money moves through the platform), it's excellent.
- Where it leaks: It's transactional-first by architecture.Every screen assumes checkout, Stripe Connect, payouts, escrow. And, the detail most “alternative” articles miss, even a buyer-seller conversationcounts as a metered “transaction.” If you're building a listings-and-contact site with no checkout, you're paying transaction-engine prices for machinery you'll never use, and you're metered on the one feature you actually want. (I broke down Sharetribe's pricing and that transaction gotcha in full here.)
- Who it's for: Transactional marketplaces. Decidedly not the listings-and-contact majority.
Classifieds scripts vs marketplace software
Osclass, Yclas, and Flynax are classifieds scripts: no-checkout is their default, listings are the product, but the UX ranges from dated to modern and none has solved distribution (buyers are still on Facebook, not your site). Sharetribe is marketplace software: modern and polished, but built for transactions, and priced to punish the no-checkout customer.
