Osclass

Overview

Osclass is a self-hosted classifieds and directory platform for people building marketplaces, job boards or niche listing sites on their own web hosting. It suits technically capable operators who want control over the software and site structure; its strongest appeal is a free open-source core, while paid extras and server maintenance make it less suitable for anyone seeking a turnkey hosted service.

The project started in 2011, with OsclassPoint taking over active development and maintenance in 2020. Its products are managed by AB profitrade, s.r.o., registered in Slovakia. The software runs as a web application rather than a native mobile app.

Key features

Listings and site customization

The core combines listings, nested categories, custom fields, comments, media uploads, user accounts, moderation, locations and currencies in an administration backoffice. Listing approval and seller messaging support practical marketplace workflows. Themes and plugins can use hooks, filters, child themes, custom CSS and JavaScript, and theme routes, so operators can tailor a site without modifying core files. That flexibility is useful for niche directories, but it also means the core does not arrive as a finished, branded marketplace.

Search and internationalization

Canonical URLs, hreflang, relevance sorting, RSS controls and configurable search URL rules—up to 26 patterns—give operators meaningful control over search and indexing. Staging noindex settings help keep development sites out of search results. Built-in .po/.mo translation support, multiple active languages, RTL where the selected theme supports it, utf8mb4 emoji and locale currencies make international sites possible, though language packs and geolocation SQL data must be added separately.

Payments and integrations

Paid Osclass Pay adds featured listings, publishing fees, wallets, memberships and connectors including Stripe, PayPal, bank transfer and regional gateways. Those are important revenue tools, but they are not part of the free core. Free extensions connect Cloudflare Turnstile and analytics services including GA4, Yandex, HotJar and Piwik, with custom head and footer snippets also supported.

Operations and requirements

Operators get searchable action logs, IP or email-pattern bans with hit counts and expiry, SMTP diagnostics, backups, maintenance mode and configurable log retention. Installation requires PHP 7.4 or later with CURL, MySQLi and GD, plus MySQL 5.7 or later or MariaDB. The base install needs 10 MB of disk space; after uploading the roughly 7 MB package, the web installer usually takes about one to two minutes once database credentials are ready. The modest base footprint does not remove the need to provision and maintain a compatible server.

Pricing

Osclass core costs nothing under Apache License 2.0 and is self-hosted. It provides the foundation for a site, including listings and administration features, but themes, plugins, language packs and geolocation SQL data are added separately. Commercial themes and plugins cost extra, so the free starting point is not a guarantee that a complete production site will be free.

For buyers who want packaged add-ons, the Starter Bundle costs €199.99, paid once and includes 20 items, with a stated 55% saving. Premium Bundle costs €399.99, paid once for 52 items and a stated 70% saving. Ultimate PRO Bundle costs €499.99, paid once for 150+ items and a stated 85% saving. The larger bundles suit operators expecting to assemble a broader feature set; the Starter Bundle is the lower-commitment paid option. These are one-time prices, not recurring subscriptions.

Platforms

Osclass is self-hosted web software. Its web interface can serve users on mobile browsers, but it is not a native mobile app. Operators supply hosting that meets its PHP and database requirements.

Who it's for

Choose Osclass if you want to run a classifieds marketplace, real-estate or car directory, job board or niche selling site and are prepared to manage hosting, configure the software and select extensions. It is especially compelling when ownership and customization matter more than having a ready-made hosted service. Look elsewhere if you need a managed platform or expect payment tools and a complete theme-and-plugin setup in the base price.

Pros and cons

• Pros: The Apache-licensed core is free and self-hosted, leaving operators in control of their site and deployment.
• Pros: Listings, moderation, messaging, categories, custom fields and an admin backoffice provide a substantial starting toolkit for directory and marketplace workflows.
• Pros: Hooks, filters, child themes and theme-level customization allow site-specific changes without editing core files.
• Pros: SEO controls, multilingual support and locale currencies suit operators serving distinct markets.
• Cons: Payment monetization depends on the separately added premium Osclass Pay extension.
• Cons: Themes, plugins, language packs and geolocation data require separate installation, and commercial add-ons can add to the cost.
• Cons: Operators must provide and maintain a server that meets the PHP and database requirements; there is no native mobile app.
• Cons: Technical issues go to community forums, while business, legal and partnership topics use a contact form, so support is not presented as a bundled paid-plan service.

Verdict

Osclass is a strong fit for technically capable operators who want a free, customizable foundation for a self-hosted classifieds or directory site. Its broad core and extensible architecture are the main reasons to choose it; the need to manage hosting and acquire some capabilities separately is the main reason to look elsewhere.
