# Pubner > Pubner is a code-first, multi-tenant CMS built on Laravel and Twig, with a built-in AI copilot that manages content, SEO and settings across every tenant site from one Hub. Pubner targets agencies and freelance developers who run multiple client sites. Each site is fully isolated (multi-tenant), themes are plain Twig templates, and the AI Assistant acts on a site's real data — records, content, settings — instead of just generating static markup. Every site ships with Full Export: the underlying Laravel/Twig code always belongs to the owner, no platform lock-in. Key facts: Laravel, PHP, Twig templating, PostgreSQL, multi-tenant SaaS CMS, agency-oriented (Hub manages many client sites), AI copilot with tool-use over tenant data, full code export, Free and Premium ($20/month) plans. ## Product - [Homepage](https://pubner.com/en): product overview and the AI copilot pitch. - [Features](https://pubner.com/en/features): full feature list. - [Pricing](https://pubner.com/en/pricing): Free and Premium plan limits and pricing. - [About](https://pubner.com/en/about): why Pubner exists. ## Docs - [Documentation](https://pubner.com/en/help): Twig templating reference, AI vs Expert mode, routing/SEO helpers, forms, localization, the record builder. - [Full documentation (single file)](https://pubner.com/llms-full.txt): the same content, concatenated for bulk ingestion. ## Optional - [Privacy Policy](https://pubner.com/en/privacy) - [Terms of Service](https://pubner.com/en/terms)
