What is Osclass?

Osclass is a self-hosted open-source PHP classifieds CMS for ads sites and multi-vendor marketplaces. Listings, categories, custom fields, user accounts, moderation, media, SEO routes, and oc-admin ship in core. Install on ordinary LAMP hosting: ~7 MB ZIP, PHP 7.4+, CURL/MySQLi/GD, no Composer for core. With DB credentials ready, the web installer usually finishes in about 1-2 minutes after upload, then you own the files and database.
Teams often pick Osclass as a self-hosted Craigslist alternative (some search for it as a Craigslist clone script) or as a lighter path than WordPress-plus-plugins stacks: one classifieds codebase, no unused portal framework. See features, the software comparison, and project history.

Multilingual classifieds out of the box

66 community language packs with standard .po/.mo files

Reach local and international users with 66 community language packs. Install Spanish, French, Arabic, German, and many more from day one, or edit catalogs in oc-admin / Poedit and share fixes via Provide to community.
Osclass can use automatic translation services such as DeepL and works with tools like POEditor for agency or team workflows. Pair languages with country geolocation packs for accurate region and city filters.

Scales from shared hosting to VPS and cloud

Unlimited listings, categories, and custom fields in core

Start on shared hosting for early traffic, then move to VPS or cloud when search filters, images, and concurrent publishes grow. OsclassPoint cites more than 120,000 people who have chosen Osclass over the project's life (cumulative adoption, not a live census). WebTechSurvey finds about 1,700 live installs today. Large listing counts are an ops problem (indexes, cache, media), not a license wall. Security fixes ship in the current 8.x line; CVE history and how to report an issue are on the security page.
Core supports unlimited listings, categories, and custom fields. Capacity planning details: best hosting for Osclass, the cloud vs VPS guide, and the architecture guide.

One script for many niche marketplaces

Real estate, vehicles, jobs, services, and local goods

Use the same classifieds core for real estate listings, a vehicle or car parts site with vehicle make/model filters, a job board, freelancer services, second-hand electronics, fashion, or a city marketplace. Categories and custom fields shape the publish form and search filters for each vertical.
Attribute plugins for cars, real estate, and jobs add structured fields (mileage, property type, salary range) without rewriting core. Step-by-step guides: car and vehicle classifieds, real estate classifieds, and job board. Choosing a vertical: profitable niche marketplace ideas.

oc-admin: listings, users, and SEO settings

Moderate ads and configure the site from one backoffice

The oc-admin panel covers listing moderation, users, categories, media, reports, statistics, mail templates, spam controls, backups, and upgrades. Non-developers handle day-to-day ops; developers stay in themes, plugins, and hooks.
Tune permalinks, canonical and hreflang options, maintenance mode, and search rules without editing PHP. Try the admin demo, then read the usability guide for multi-vendor and daily workflow notes.

Responsive themes with search and RTL support

Mobile-first layouts for classifieds browse and publish flows

Ship with a mobile-first theme (Sigma ships in core) or pick premium designs from OsclassPoint. Themes stay light for listing grids and filters, and many support RTL locales when you enable Arabic, Hebrew, or similar packs.

Monetize listings and marketplace sales

Osclass Pay with Stripe, PayPal, and regional gateways

Charge for visibility and access with the Osclass Pay plugin: Stripe (SCA-ready cards), PayPal, and regional options such as Razorpay, Paystack, and Authorize.Net.
Common revenue models: publish fees, Featured / Premium, Highlight, Move to Top, wallets and credit packs, memberships, and multi-vendor checkout where buyers pay sellers through the same stack.
Ops detail: turn on paid visibility covers callbacks, staging tests, and fee rollout order.

Hooks, themes, and plugins (not a core fork)

Extend Osclass the same way WordPress sites use plugins

Osclass keeps custom work in themes, plugins, and hooks/filters so upgrades stay practical. Prefer that path over editing oc-includes. The extension model will feel familiar if you have shipped WordPress plugins, without running WordPress as the host CMS.
Browse Osclass themes and plugins on OsclassPoint, start with the free Osclass themes and plugins, or follow the hooks and plugins guide for safe customization.

Frequently asked questions

What is Osclass used for?
Osclass is free open-source PHP and MySQL software for self-hosted classifieds websites and marketplaces. Core includes listings, categories, custom fields, user accounts, moderation, media uploads, SEO routes, and oc-admin management.
Can Osclass run a car, real estate, or job board website?
Yes. The same core runs every listing vertical: categories set the browse path and custom fields set the filters, such as make and model for cars, property type and rooms for real estate, or salary and contract type for jobs. Each vertical has its own guide on this site with a category tree and field list.
How do I choose the best classified ad script?
Score candidates on filtered search latency, moderation logs, payment callback recovery, URL and export control, and staged upgrades. Prefer a dedicated classifieds script when ads are the product; prefer WordPress or Joomla when editorial CMS already leads. Use the classified ad script comparison for the pilot scorecard.
Is Osclass a Craigslist clone script?
Osclass is often used as a self-hosted Craigslist alternative or clone script for local and niche listings on your own domain and database. It does not copy the Craigslist layout or rules: you choose the theme, categories, and moderation policy.
Is Osclass free to install?
Yes. Osclass core is free and self-hosted under the Apache License 2.0. You pay for hosting and optional commercial themes, plugins, or customization services.
Can Osclass run paid listings and payments?
Yes. Sites commonly use Osclass Pay for featured listings, publish fees, wallets, memberships, and gateways such as Stripe or PayPal. Test payment callbacks on staging before go-live.
Does Osclass need WordPress or a PHP framework?
No. Osclass is a standalone classifieds application. It does not require WordPress, Joomla, Laravel, Symfony, or Magento. Themes and plugins extend classifieds features without a separate CMS host.
How many security CVEs does Osclass have compared with WordPress?
OpenCVE lists about 10 CVEs for Osclass (mostly old 2.x/3.x). WebTechSurvey finds about 1,700 live Osclass sites. Patchstack counted 11,334 WordPress-ecosystem vulnerabilities in 2025 alone across tens of millions of sites. Fewer Osclass CVEs reflects a smaller install base and surface, not zero risk; stay on current 8.x and patch plugins. The security page explains how to report a vulnerability.
