Osclass

Overview

Osclass is a self-hosted classifieds platform for operators building marketplaces, real-estate directories, car listings, job boards or niche sales sites. It is best suited to people comfortable managing a web server and extending software themselves. Its appeal is a capable free core; the trade-off is that themes, plugins and some localization resources may need separate installation or purchase.

Key features

Listings and customization

The core brings listings, nested categories, custom fields, comments, media uploads, users, moderation, locations and currencies together in the oc-admin backoffice. Listing approval and seller messaging support basic marketplace operations. Hooks, filters, child themes, custom CSS and JavaScript, and theme routes allow changes without editing core files—a useful degree of control for a tailored directory, but less turnkey than a hosted service.

Search and languages

Canonical URLs, hreflang, relevance sorting, RSS controls and up to 26 custom search URL patterns give operators practical control over search presentation. Staging noindex settings help keep development sites out of search results. Built-in .po/.mo translations support multiple active languages, RTL where the chosen theme supports it, utf8mb4 emoji and locale currencies. Language packs and geolocation SQL data are added separately, so a multilingual or location-rich launch may take additional setup.

Payments and operations

Featured listings, publish fees, wallets, memberships and payment gateways such as Stripe, PayPal, bank transfer and regional providers come through the premium Osclass Pay extension, not the core. Free extensions provide Cloudflare Turnstile and analytics integrations for GA4, Yandex, HotJar, Piwik and custom snippets. Searchable action logs, ban rules with hit counts and expiry, SMTP diagnostics, backups, maintenance mode and configurable log retention offer useful administration controls, though operators remain responsible for their own hosting.

Pricing

Osclass core costs nothing under the Apache License 2.0 and is self-hosted. The free core is the sensible starting point for technically capable operators who can supply hosting and add only what their site requires. It does not bundle every theme, plugin or language resource, and commercial extensions are sold separately.

For buyers who want a packaged collection of add-ons, the one-time bundles are Starter Bundle at €199.99, paid once for 20 items (save 55%), Premium Bundle at €399.99, paid once for 52 items (save 70%), and Ultimate PRO Bundle at €499.99, paid once for 150+ items (save 85%). The larger collections suit operators who expect to use more extensions; the smaller purchase limits the upfront spend but includes fewer items. These are add-on bundles rather than replacements for the self-hosted core.

Platforms

Osclass runs as self-hosted web software, not a native mobile app. Installation requires PHP 7.4+ with CURL, MySQLi and GD, plus MySQL 5.7+ or MariaDB; a base installation needs 10 MB of disk space. With database credentials ready, uploading the approximately 7 MB package and completing the web installer usually takes about 1–2 minutes. That modest base footprint is attractive, but server compatibility and upkeep are the operator's responsibility.

Who it's for

Choose Osclass if you want to own the hosting and shape a classifieds site around specific categories, fields, languages or workflows. It is a weaker fit if you need a managed service or expect payments, a finished theme and localization materials to be included in the initial install. Technical issues are directed to community forums; business, legal and partnership topics can go through the contact form.

Pros and cons

• Pros: The free, open-source core includes a broad set of listing, moderation, SEO and administration functions, avoiding a software license charge for a self-hosted launch.
• Pros: Hooks, filters and theme-level customization let operators adapt the site without editing core files.
• Cons: The core is not a complete turnkey storefront: themes, plugins, language packs and geolocation data are added separately, and commercial extensions cost extra.
• Cons: Self-hosting requires a compatible PHP and database stack and leaves server operations to the site owner.
• Cons: Payment collection depends on the premium Osclass Pay extension rather than the core installation.

Verdict

Osclass is a strong fit for technically capable operators who want a flexible classifieds core without an initial software charge. Its broad built-in toolkit and customization hooks are the main reasons to choose it; look elsewhere if you need a managed, ready-to-run service or want payment tools and site assets bundled from the outset.
