Do you want to buy a ready-made free classifieds board (website)?

Building a business based on the concept of free classified ads is a highly profitable investment, proven by the decades-long success of such market giants as «Iz Ruk v Ruki» (Hand to Hand) or «Avito».

A market participant urgently needing to sell their product or service is willing to pay a relatively modest amount to achieve a quick and optimal result: attracting customers through ads posted on the website. Offering exclusive services — such as placing an ad in the highest available position among similar listings — benefits both the seller and the website owner: the seller moves their product or service, while the site owner earns revenue from the provided services.

How much does it cost to build a classified ads website?

There is no single answer to this question. In theory, you can download a ready-made classifieds website (as an OpenSource program) and install it on your hosting — this is what 99% of those wishing to launch their own «board» do. The result is yet another faceless website nobody needs, which with 99% probability will cease to exist after a while due to lack of demand and user interest, because it will be as alike as two peas in a pod to similar resources built on the very same «engine». But if you want a product that does not look like the other resources in this niche, then:

Hiring programmers to develop a classifieds board «from scratch» will cost you 250—300 thousand RUB in monthly salary for just one developer.
When it comes to classifieds websites like «Avito», their development and maintenance costs approach truly astronomical figures.

A solution based on the Котики-даром.рф software platform

If you are considering purchasing a classifieds board «engine» and looking for where to buy or order a turnkey classifieds website, we can help you with that: we offer a solution based on our software platform that powers Котики-даром.рф. Here are the key technical specifications of our solution:

The software platform is not OpenSource — the source code is not available to anyone; development was done entirely in-house. Consequently, the functionality and design of the site are unique in their own way.
The software platform is written on the PHP 8.4+ / MySQL / Memcached stack, following the MVC methodology with an implementation of the Data Mapper pattern (a clear separation between business logic and the data access layer).
Strict typing throughout the codebase — a whole class of errors is filtered out at the development stage rather than on the live site.
A proprietary database library — complete protection against SQL injections, one of the most common types of attacks on websites.
Valid HTML markup, separated from the business logic of the program code.
An administration panel is included.
High-quality, transparent program code, divided into domain objects and data sources.
Over 100 ready-made thematic categories; the category tree is freely configurable through the administration panel for any niche.
Templates and modules optimized for SEO promotion: structured markup for search engines, automatic site map generation (sitemap.xml), canonical page URLs.
Modular code structure: 20 ready-made modules — ads, users, categories, authorization, payments, mailings, articles, videos, captcha and others.
Detailed technical documentation included: architecture, data layer, caching, templates, validation, deployment, multilingual support and other aspects.

Out-of-the-box functionality

This is not just a skeleton for a classifieds board, but a finished product proven in real-world operation on commercial projects. The package includes:

Multilingual support — 6 interface languages (Russian, English, Armenian, Kazakh, Georgian, Serbian) with URL prefixes (for example, /en/, /hy/). Adding a new language is a routine task with a ready-made step-by-step guide.
Multi-domain support — a single software platform serves several websites (currently — Котики-даром.рф), each with its own set of categories, templates, texts and business logic, on a shared codebase.
Multi-country support — a built-in hierarchical tree of territories (country → region → city), ad filtering at any level. Ready-made territory directories for Russia, Armenia, Kazakhstan, Georgia and other neighboring countries.
Anonymous ad posting with automatic linking to an account after registration — lowering the entry barrier for new users.
E-mail confirmation, e-mail authorization and password recovery out of the box.
Image upload with automatic generation of thumbnails in the required sizes.
Automatic profanity filtering in ad texts.
A system of paid services — raising an ad in the listing, VIP, pinning and others; ready-made integration with the Prodamus payment service.
Mail queue — e-mails are sent in the background and do not slow the site down; e-mail templates are translated into all supported languages.
Bot protection — a proprietary CAPTCHA and an IP address blacklist with support for blocking entire subnets.
Ad archive — automatic archiving of outdated listings and restoration when needed.
Content sections — multilingual articles and a short-video feed: ready-made tools for attracting search traffic and retaining the audience, fully managed from the administration panel.
A ready-made set of legal documents — personal data processing policy, public offer, user agreement, consents, a cookie consent banner.
Compliance with the Russian personal data law (152-FZ) — a complete account deletion cycle at the user's request: destruction or anonymization of the data and automatic generation of a confirming statement in accordance with Roskomnadzor requirements.
A ready-made set of cron jobs: deleting expired ads, clearing VIP statuses, recalculating counters by territory, generating sitemap.xml, database backups, sending notifications.
A flexible data validation system (e-mail, phone, URL, string length, ranges, etc.) — everything users enter is checked before being written to the database.
Memcached caching in all hot spots (mappers, category lists, territory counters) — the site withstands high load without vertical scaling.

Ready-made deployment infrastructure

The package includes a complete Docker configuration for dev and prod environments — a working copy of the site can be brought up on a new server in a matter of minutes:

Separate containers for PHP-FPM, nginx, MySQL, Memcached, cron and postfix — deployment with a single command.
A unified configuration format for the test and production environments.
Preconfigured cron jobs, log rotation and database backups.
Detailed guides on deployment and day-to-day maintenance are included.

LLM-friendly code (AI-assistant friendly)

Separately, let us highlight a feature that matters in 2026: modern AI assistants (Claude Code, GitHub Copilot, ChatGPT and the like) do an excellent job of maintaining and evolving this code — unlike typical legacy PHP projects, where an LLM gets lost in framework «magic», implicit dependencies and non-standard conventions.

Why it works:

Dedicated documentation for LLMs (the CLAUDE.md file) and a whole library of reference guides for each subsystem — the assistant finds its bearings in the project right away, without manual explanations.
A uniform module architecture — all modules are structured identically. Having understood the structure of one module once, an LLM confidently edits any other.
Strict typing and detailed method signatures — the assistant does not guess types but «sees» the contract, which radically reduces the number of «trial-and-error» edits.
No «magic» — the behavior of the code is easy to trace from the entry point to the final database query, with no hidden dependencies or code generation.
A single documented naming style for files, tables, styles and text constants — an LLM generates code in the project's style without additional hints.
Verifiable changes — self-diagnostic scripts are included (for example, an automatic completeness check of the translations across all languages): the assistant runs the checks itself after making edits and sees the result.
A reference guide for every key feature — a separate document describing how it works and where its boundaries are. An LLM uses it as a ready-made instruction when making improvements and implementing similar tasks.

What this gives the site owner in practice:

Most edits and small features can be done by the hands of an AI assistant in minutes rather than hours.
Dependence on expensive senior PHP developers decreases — a middle developer paired with an LLM copes with the routine.
Adding a new language, a new section or a new paid service, translating a template — routine tasks that an LLM performs following the ready-made guides.
The total cost of owning and developing the project is several times lower than that of a typical classifieds board on a heavy framework with a large number of dependencies and complex infrastructure.
