Flex Fields, Forms, Shortcodes, Redirects, SMM & SEO, Cache, SMTP, SSL, Website Security, Translate, Maintenance, and Clone — built as small, focused plugins you can use together or one at a time.
Twelve plugins that work together or standalone. Free on WordPress.org, maintained by Flex.
Maintenance
Put a public splash in front of the site while you build or repair it. Logged-in administrators still see the real site.
Schedule start and end times, share a secret bypass link, and purge Flex Cache when the splash turns on or off.
Duplicate
Copy content you already have so you can edit the duplicate instead of starting over.
Works with custom post types, WooCommerce products, Flex Fields meta, and a local history of the last 100 clones.
Custom fields
Add reusable field groups with ACF-style location rules, conditional logic, and REST / revision support.
Works across post types, taxonomies, user profiles, and Global Options, including Polylang-aware option keys.
Security
A lightweight toolkit — not a full WAF — that reduces brute-force logins, XML-RPC abuse, and user enumeration.
Optional Cloudflare Turnstile or Google reCAPTCHA, country rules, and a custom login URL.
Performance
Serve cached HTML for anonymous visitors before WordPress fully loads.
Optional Redis store; files stay as backup. No object-cache.php and no remote calls.
The mail layer for the FLEX suite — Flex Forms and anything using wp_mail() can leave credentials out of form settings.
HTTP API sending uses wp_remote_post only; no vendor SDKs and no telemetry.
Forms
Build forms in the admin, store submissions, and send email notifications without a heavy form suite.
Pairs with Flex SMTP for delivery and Flex Fields when you need custom data on the same site.
Redirects
Exact, prefix, and regex matching before the theme loads.
Hit counters, optional 404 logging, CSV import / export, and a dry-run tester.
Multilingual
Translate strings with ft() and posts with the same slug per language.
Path-based URLs such as /ru/about, plus a language switcher helper.
Content
Store HTML once and reuse it in posts, pages, widgets, and templates.
Parameters fill {{placeholders}}; nested shortcodes are allowed, circular includes are blocked.
SEO & social
Titles, Open Graph, Twitter/X cards, XML sitemaps, and JSON-LD from one plugin.
Optional Search Console and GA4 Insights via your own Google Cloud OAuth client.
HTTPS
Redirect HTTP to HTTPS, update site URLs, and fix mixed content on your own domain.
Reads X-Forwarded-Proto from Cloudflare so Flexible SSL does not loop.
