Answers to common questions about GriD12 — pricing, features, security and how it works. Can’t find what you are looking for? Contact us.
What is GriD12?
GriD12 is a configuration-driven PHP framework that turns a MySQL or MariaDB table into a complete, secure CRUD screen — no build step, no external dependencies. Write a small configuration array, include one file, and the grid runs immediately. See How it works for the full three-step workflow.
Is GriD12 free to use?
Yes. The Free edition gives you read-only grids — search, sorting, pagination and lookups — with no time limit. Paid editions add Create, Update, Delete, CSV/PDF export and more; see the full plan comparison.
How much does GriD12 cost?
One-time developer licenses range from €59 (Basic) to €449 (Ultimate), each including one year of free updates and support and backed by a 30-day money-back guarantee. Full breakdown on the Pricing page.
Do I need to install any dependencies to use GriD12?
No. The core engine needs only PHP 8.1+ and MySQL/MariaDB — every UI asset (Bootstrap, Select2, flatpickr) loads from a CDN, with nothing to compile or bundle. The one optional exception is PDF export, which requires installing the Dompdf library separately.
Which databases does GriD12 support?
MySQL and MariaDB, accessed exclusively through PDO prepared statements.
Can GriD12 handle master-detail (parent/child) screens, like an order with line items?
Yes, on the Professional plan and up. A master-detail form adds one 'detail' block to the same configuration array, and the parent record plus its repeatable child rows save together in a single transaction. See the Master-Detail Forms documentation.
Is GriD12 secure?
Every value is handled through PDO prepared statements, table and column names are whitelisted against the live database schema, forms are protected with CSRF tokens, and all output is escaped to prevent XSS — security is the default, not an add-on.
Which languages does the interface support?
English, Greek, German, Spanish, French and Italian out of the box, with localized month names and number formats. Adding another language is a single file.
How is the Free vs. Paid edition determined?
Purely by which optional PHP files are present on disk — there is no license key to enter. Dropping create.php, update.php and delete.php into the installation upgrades it to full CRUD.
Can I try the full Create, Read, Update, Delete workflow before buying?
Yes. The public live demo is read-only, but you can contact us for a 12-day trial with complete CRUD access.
Does GriD12 work on mobile devices?
Yes, every grid renders a responsive Bootstrap 5 interface that adapts to phones, tablets and desktops.
Can I export data to CSV or PDF?
CSV export is included in every paid edition. PDF export is also available on paid editions once the optional Dompdf library is installed — see the PDF Export documentation.
Who develops GriD12?
GriD12 is developed by Byte12.com, led by Stefanos Gkoutziantamis, Full Stack Developer and project manager of the GriD12 team.
Where can I find the full technical documentation?
The complete configuration reference — every column type and option, theming, localization and the security model — is in the GriD12 documentation.
