Open Source Classifieds Script & Marketplace Software

Build a self-hosted marketplace or start a successful classifieds website for free

Osclass is a free open-source classifieds script for PHP and MySQL. Use it to run a local marketplace, real estate directory, car classifieds site, job board, or niche selling platform on hosting you control. Operators choose it when they want classified ads software they own: domain, database, moderation rules, and SEO URLs.
Compressed core is about 7 MB, runs on PHP 7.2+ (CURL, MySQLi, GD), and does not need WordPress, Joomla, Laravel, or Symfony. With DB credentials ready, the web installer usually finishes in about 1-2 minutes after upload. Built-in .po/.mo translations, country geolocation packs, themes, and plugins. Active 8.x releases from OsclassPoint. See the classified ad script comparison or the guide to build a powerful marketplace.

Osclass themes and marketplace overview

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 7.2+, 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-style alternative 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

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

Reach local and international users with 63 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 states that more than 120,000 people have chosen Osclass; WebTechSurvey finds about 1,700 live installs. Large listing counts are an ops problem (indexes, cache, media), not a license wall. OpenCVE lists about 10 Osclass CVEs (mostly old 2.x/3.x), a thinner stream than WordPress (11,334 ecosystem vulns in 2025) or Magento/Adobe Commerce on vastly larger install bases. Stay on current 8.x if scanners still fingerprint older version 3 installs.
Core supports unlimited listings, categories, and custom fields. Capacity planning details: cloud vs VPS guide and 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, 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. Niche fit notes: niche ideas guide and job board guide.

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: monetization playbook 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 free and premium products on OsclassPoint, or follow the hooks and plugins guide for safe customization.

OsclassPoint: templates, payments, SEO, and ops extensions

OsclassPoint is the official sister marketplace for Osclass themes and plugins. Connect an API key in oc-admin to install and update products from Market, or download packages manually.
Typical catalog needs: payment gateways, spam controls, SEO helpers, forums, blogs, attribute packs, and performance tools. Core stays free; extensions are optional.

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.
How do I build a powerful online marketplace with Osclass?
Install the PHP classifieds core, lock taxonomy and searchable fields, seed real listings, name a moderator, prove mail and system cron, then scale indexes, cache, and fees as inventory grows. Architecture detail lives in the build a powerful marketplace guide; launch ops live in the successful classifieds site guide.
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 self-hosted Craigslist alternative?
Yes for operators who want local or niche listings under their own domain and database. Osclass is not a Craigslist clone of layout or policy; it is a classifieds script you install and moderate yourself.
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.
