Host your tenants effortlessly on a single domain using our new Path-Based Routing (e.g., example.com/site/abcdef), or map them to full custom domains. It is the perfect, lightweight, drop-in replacement for WordPress Multisite built for simplicity and scale. 📖 Complete Documentation: grabwp.com\ 💻 Source Code: GitHub Repository\ 🐛 Report Issues: GitHub Issues Core Features

Shared MySQL Database: Cost-effective tenant isolation using unique table prefixes
Separated Upload Directories: Each tenant gets isolated upload directories
Shared Themes & Plugins: All tenants share the same themes and plugins for simplicity
Flexible Routing Options: Choose between domain-based routing or our new path-based (subdirectory) routing for an effortless setup without DNS changes.
Basic Admin Interface: Simple tenant management through WordPress admin
Early Initialization: Plugin loads before WordPress core hooks

1.1.2

Security: Replaced the file-based admin access token (a secret written to tokens.php and consumed via rename) with stateless HMAC-SHA256 tokens bound to the tenant ID, signed with AUTH_KEY/AUTH_SALT and given a short TTL (default 30 minutes, configurable via GRABWP_TENANCY_TOKEN_TTL). No token secret is persisted to disk anymore.
New: The clone "complete" screen now shows the target tenant ID with quick links to Edit tenant, Homepage, and Dashboard.
Enhance: Admin UI refactor — inline styles moved into a shared stylesheet (admin/css/grabwp-admin-shared.css) with utility classes; section show/hide now toggles a hidden class.
Change: Clone pipeline reordered — site URL replacement now runs before copying uploads.
Change: Installer removes legacy tokens.php / .consumed artifacts on activation; removed the now-unused get_tokens_file_path() helper.

1.1.1

Security: Admin access tokens are now single-use — consumed atomically on first successful login; concurrent or replayed token requests are rejected.
Security: Domain hash validation is mandatory for admin token login; comparisons use timing-safe hash_equals().
Security: Path-based admin URLs no longer expose tenant_domain in the query string; hash validation uses internal routing context instead.
Enhance: Added GrabWP_Tenancy_Path_Manager::atomic_put_php_file() for atomic writes of settings, tenant mappings, and admin token files (tmp + rename, ABSPATH guard, OpCache invalidation).
Fix: Tenant clone file copy now skips symlinks, preventing accidental duplication of shared plugin/theme directories.
Fix: WordPress cron requests again run in mainsite context (tenant detection disabled during DOING_CRON).

1.1.0

Refactor: Split early-boot load-helper.php into focused modules (security, server detection, tenant detection, boot constants, cache) — same boot behavior, easier maintenance and extension.
Refactor: Extracted admin form handling, tenant CRUD, and domain validation into dedicated classes (GrabWP_Tenancy_Admin_Form_Handler, GrabWP_Tenancy_Tenant_Crud, GrabWP_Tenancy_Domain_Validator); public handle_create_tenant(), handle_update_tenant(), and handle_delete_tenant() methods remain for backward compatibility.
Refactor: Status page reorganized into tab partials with centralized environment checks via GrabWP_Tenancy_Status_Checker (General, Base Plugin, Pro Plugin tabs unchanged).
Fix: Settings page now shows the "Settings saved successfully." notice after saving (previously redirected but notice was never displayed).
Developer: All existing action hooks (grabwp_tenancy_before_create_tenant, grabwp_tenancy_after_create_tenant, etc.) preserved; no migration required.

1.0.11

New: Cache isolation for tenant context — disables page-cache drop-ins per tenant request (WP_CACHE) and prefixes object-cache keys with the tenant ID (WP_CACHE_KEY_SALT) to prevent cross-tenant cache collisions on shared Redis/Memcached backends.
New: Added grabwp_tenancy_get_tenant_url() helper to resolve a tenant front-end URL by ID without loading a full tenant object.
Enhance: Centralized tenant URL resolution — get_site_url(), get_admin_access_url(), and static helpers (resolve_site_url(), resolve_admin_url(), build_site_url()) now handle domain-based and path-based routing in one place; tenant list and clone flows use these shared methods.
Enhance: Log messages are automatically prefixed with [tenant_id] or [Mainsite] for easier multi-tenant debugging.

1.0.10

Fix: Tenant directory cleanup now handles symlinks safely during recursive deletion, removing only the symlink itself instead of following it into the original shared plugin or theme directory.
Enhance: Tested up to WordPress 7.0.

1.0.9

Fix: Default tenant data directory moved from wp-content/uploads/grabwp-tenancy to wp-content/grabwp-tenancy (outside uploads) to prevent direct web access to tenant data. Existing installs that already use the uploads path are preserved automatically — no migration needed.
Fix: Corrected legacy-path migration notice in the Status page to use WP_CONTENT_DIR directly instead of wp_upload_dir(), matching the new default path.
Fix: Downgraded oversized "Clone to existing site" / "Clone to new site" hero buttons on the clone page to standard buttons for visual consistency.
Enhance: Plugin/theme admin bar nodes (plugins, themes) are now removed on tenant sites when the corresponding Hide Plugin Management / Hide Theme Management settings are enabled, closing a gap where the toolbar still exposed those links.
Enhance: Tenant create page UX — the first domain field is now auto-filled with a suggested domain (tenant-{6digits}.{hostname}); a new Clear button lets users wipe the field quickly; the domain input grows up to 500 px wide; and the domain section is visually indented under its radio button.
Enhance: GrabWP Tenancy admin menu position moved higher (position 3) so it appears near the top of the sidebar.
Change: Default values for Hide Plugin Management and Hide Theme Management settings changed from true to false for fresh installs, giving new tenants full access by default until explicitly restricted.

1.0.8

New: Tenant Cloning — clone any existing tenant (or the mainsite) to a new tenant, including database tables and uploaded files with automatic URL replacement.
New: Added GRABWP_MAINSITE_ID constant (__mainsite__) to allow the main site to be used as a clone source.
Enhance: Mainsite domain detection now supports localhost and local-network domains that have no TLD extension (e.g., mysite.local, bare localhost).
Fix: Resolved plugin asset URL resolution on hosts where the plugin directory is symlinked — switched to content_url() to avoid incorrect absolute paths.
Fix: Refactored tenant ID generation to guarantee uniqueness and avoid collisions on busy installations.
Quality: Normalised all PHP source files from CRLF to LF line endings.

1.0.7

Major: Introducing Path-Based Routing! You can now host tenants on subdirectories/paths (e.g., example.com/site/abcdef) without requiring separate domains. This completely eliminates the need for complex domain mappings and serves as a true, lightweight replacement for WordPress Multisite.
Enhance: Added comprehensive .htaccess diagnostic admin notices specifically tailored for path-based routing support.
Enhance: Centralized configuration and diagnostic tools into a transparent, read-only Status Page UI with manual fallback instructions for environment issues.
Refactor: Streamlined the installation, uninstallation, and environment-fixing processes into a single GrabWP_Tenancy_Installer class.
Security: Improved code compliance by integrating complete nonce verification on sensitive administrative handlers and securely transitioning to wp_is_writable().
Fix: Resolved PHP fatal errors (e.g., Class Not Found) relating to the class autoloader sequence during the initial activation process.
Quality: Standardized codebase formatting for consistent line endings (CRLF to LF) and file encoding across all files.

1.0.6

New: Dedicated Status admin page with system information, file structure, database config, content isolation, and domain routing details (moved out of Settings page)
New: One-click Auto Install MU-Plugin button with AJAX handler — auto-creates the must-use plugin file, or shows copy-to-clipboard fallback when the directory is not writable
New: One-click Auto Install to wp-config.php button with AJAX handler — injects the load.php require line before the stop-editing marker, or shows copy-to-clipboard fallback when wp-config.php is not writable
New: Admin notices for missing MU-plugin and missing wp-config.php loader, shown only on plugin pages, with writability-aware UI (auto-install vs. manual copy)
New: Pro Features section added to the plugin readme
Improved: Default tenant capability settings are now enabled (Disallow File Mods, Disallow File Edit, Hide Plugin Management, Hide Theme Management) for stronger security out of the box
Improved: Added fallback definition of grabwp_tenancy_validate_tenant_id() in Path Manager so validation works even when load-helper.php is not loaded
Improved: Tenant edit page title now displays the tenant ID for clarity
Improved: Moved AJAX nonces (muPluginNonce, loaderNonce) into localized admin script data
Improved: Refactored JS — extracted bindCopyButton() helper, added initMuPluginInstall() and initLoaderInstall() handlers in grabwp-admin.js
Improved: Streamlined load-helper.php base-dir resolution logic and added GRABWP_TENANCY_DIRS_FROM_PLUGIN constant
Improved: Renamed local variables in tenant views to use grabwp_tenancy_ prefix to avoid potential conflicts
Improved: Tested up to WordPress 6.9

1.0.5

New: Settings page for tenant capability controls (Disallow File Mods, Disallow File Edit, Hide Plugin Management, Hide Theme Management, Hide GrabWP Plugins)
Fix: Tenant ID starting with a number causes database errors on table prefix
