Products - A WordPress suite that stays out of the way.

Flex Fields, Forms, SEO, Security, Cache, SSL, Redirects, Translate, SMTP, and Shortcodes — built as small, focused plugins you can use together or one at a time.

WordPress plugins

Ten plugins that work together or standalone. Free on WordPress.org, maintained by Flex.

Flex Fields

Custom fields

Flex 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.

Flex Security

Security

Flex 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.

Flex Cache

Performance

Flex Cache

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.

Flex SMTP

Email

Flex SMTP

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.

Flex Forms

Forms

Flex 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.

Flex Redirects

Redirects

Flex Redirects

Exact, prefix, and regex matching before the theme loads.

Hit counters, optional 404 logging, CSV import / export, and a dry-run tester.

Flex Translate

Multilingual

Flex Translate

Translate strings with ft() and posts with the same slug per language.

Path-based URLs such as /ru/about, plus a language switcher helper.

Flex Shortcodes

Content

Flex Shortcodes

Store HTML once and reuse it in posts, pages, widgets, and templates.

Parameters fill {{placeholders}}; nested shortcodes are allowed, circular includes are blocked.

Flex SEO

SEO

Flex SEO

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.

Flex SSL

HTTPS

Flex SSL

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.
