Description
Asteris Utility Suite is the free edition of the Asteris suite. Five modules, no bloat, no upsell popups, no phone-home.
Install one plugin instead of five. Toggle modules on or off from a single dashboard. Each module does one job well and stays out of the way when you don’t need it.
What’s included:
- SMTP — send mail through your own SMTP server. Plug in Gmail / Outlook / SendGrid / Mailgun credentials, see a log of the last 50 sends.
- Image Optimisation — automatic WebP + AVIF conversion on upload and bulk-optimise your whole existing media library (background queue, pause/resume). Smart
<picture>serving sends each browser the smallest format it supports, and a derivative is only kept if it’s actually smaller. Original backup + one-click restore. - Analytics + Pixels — GA4 tag, Meta Pixel, basic Consent Mode v2. Loaded only on front-end pages, deferred to avoid blocking render.
- Activity Log — 30 day audit trail of admin actions: user logins, plugin activations, option changes, post edits. Filterable, exportable as JSON.
- Accessibility Scanner — page-by-page WCAG findings report. Catches missing alt text, low-contrast headings, skipped heading levels, links without descriptive text.
Looking for more? Asteris Utility Suite (paid) adds Security + Login, full SEO + AI suite, page caching with advanced-cache.php drop-in, scheduled cloud backups, the full Forms engine, link cloaking, and per-site Insights. See asteriscommerce.com/asteris-utility-suite.
Privacy: Asteris Utility Suite makes no outbound network calls by default. No telemetry, no licence check, no analytics on you. The Analytics + Pixels module is the only outbound traffic it ever generates — and only when you explicitly configure a tracking ID.
Why Asteris Utility Suite?
Built lean on purpose. Here’s what you actually get:
- Tiny footprint — about 160 KB zipped. Most “all-in-one” suites are 10-40 MB.
- One plugin instead of six — one thing to update, one settings area, one conflict surface instead of six separate plugins.
- Only runs what you turn on — every module toggles independently, and disabled modules load no code at all.
- Nothing loads on the front end unless it’s needed — the analytics tags are deferred and only output once you’ve actually set a tracking ID.
- No phone-home — zero telemetry, no licence check, no usage data sent anywhere. The only outbound traffic is the tracking pixels you choose to switch on.
- Modern, efficient code — built for PHP 8.1+, no jQuery dependency, no heavy framework bundled.
- Your data stays yours — everything installs and runs on your own server. Not SaaS, no account required.
- GPL-2.0 — audit it, fork it, keep it forever.
- No nag screens — the paid edition is mentioned once, never as a pop-up or a locked button.
- Built by people who run real sites — five years of agency work behind it, not a weekend side project.
Upgrade to Asteris Utility Suite (Pro)
The free plugin is complete and stays free. When you need more, the paid version adds the heavier modules — same one-plugin, no-bloat philosophy:
- Security + Login — brute-force throttling, 2FA, passkeys, malware + vulnerability scanners
- SEO + AI Suite — meta, schema, sitemaps, llms.txt, AI content generator, Search Console integration
- Performance — page caching with an advanced-cache.php drop-in, Core Web Vitals monitor, HTML rewriter
- Backups — streaming database dumps, file archives, cloud destinations, one-click restore + clone sandbox
- Forms — a full form builder with uploads, signatures, calculations and webhooks
- Links — affiliate link cloaker + click tracker
- Insights — per-site visitor analytics, plus the two-way Data sources (Search Console, Bing, GA4 Data API)
- AI Suite — AI content helpers: long copy, excerpts, SEO meta, and image alt text from a brief + your keywords (bring-your-own AI key)
- Duplicate Post — one-click clone of any post, page, or custom post type, with taxonomies and custom fields copied to a fresh draft
- The Pro tier of all five free modules
One standard price, no per-site upsells, the same lightweight build. See everything included at asteriscommerce.com/asteris-utility-suite.
External services
Asteris Utility Suite does not connect to any external service on its own. Three optional integrations inside the Analytics + Pixels module load third-party scripts only when YOU paste in the relevant tracking ID via Asteris Analytics + Pixels:
Google Analytics 4 (GA4) + Google Tag Manager (GTM)
* What: Tracks pageviews + events for your own analytics dashboards.
* When: A request is sent to www.googletagmanager.com on every front-end page load once you save a GA4 Measurement ID and/or a GTM Container ID.
* Data sent: Standard browser pageview ping (URL, referrer, user agent, screen size, language) plus any custom events you trigger.
* Provided by Google. Terms of Service · Privacy Policy
Meta Pixel (Facebook)
* What: Tracks pageviews + conversions for Meta ad campaigns.
* When: A request is sent to connect.facebook.net and www.facebook.com/tr on every front-end page load once you save a Meta Pixel ID.
* Data sent: Standard pageview ping plus any custom events you trigger.
* Provided by Meta Platforms, Inc. Business Tools Terms · Privacy Policy
If you do not enter a tracking ID for a given integration, no requests to that service are sent.
SMTP mail server (you choose the provider)
* What: When the SMTP module is enabled, outgoing site email (wp_mail()) is delivered through the SMTP server you configure — for example Gmail, Outlook, Amazon SES, SendGrid, Mailgun, or any other SMTP host.
* When: A connection is made to your configured SMTP host only at the moment WordPress sends an email, and only after you have entered host/credentials and enabled the module.
* Data sent: The contents of the emails your site sends (recipient, subject, body, headers) plus the authentication credentials you supply, transmitted to the host you nominated.
* Provided by the third-party mail provider you select. Review that provider’s own terms and privacy policy (e.g. Amazon SES, SendGrid, Mailgun). No mail is sent to any Asteris-operated server at any point.

FAQ
-
Does Asteris Utility Suite send my data anywhere?
-
No. The plugin makes zero outbound calls. The Analytics + Pixels module sends pageview pings to Google or Meta only when you turn it on and supply your own tracking IDs.
-
How do I upgrade to the paid version?
-
Buy a licence at asteriscommerce.com/asteris-utility-suite. The paid version installs over the free one in the same folder and replaces it — your settings, data, and snippets carry over automatically.
-
Can I run the free and paid versions at the same time?
-
No — and you don’t need to. The paid version is the same plugin with the full feature set unlocked; installing it replaces the free copy in place, keeping all your settings and data.
-
What’s in the paid version that’s not here?
-
Security + Login (brute-force throttling, 2FA, passkeys, malware + vulnerability scanners), full SEO + AI Suite (meta, schema, sitemaps, llms.txt, AI generator, Search Console integration), Performance (page cache + advanced-cache.php, CWV monitor, HTML rewriter), Backups (streaming DB dumps, files zip, cloud destinations, restore + clone sandbox), Forms (full builder with file uploads, signatures, calculations, webhooks), Links (affiliate cloaker + click tracker), Insights (per-site visitor analytics with mu-plugin fast-path), AI Suite (AI content helpers — long copy, excerpts, meta, alt text), and Duplicate Post (one-click clone of any post, page, or custom post type). Plus the Pro tiers of all five free modules.
-
Does it work with WooCommerce?
-
It runs alongside WooCommerce with no conflict. If you also use our separate Asteris for WooCommerce plugin, the two coordinate so you don’t get duplicate modules.

Changelog
1.0.6
- Security: the Safe-Mode kill switch now verifies the
manage_optionscapability before any cookie is set or cleared, so the exit URL (?asteris_safe_mode=0) can no longer change state via an unauthenticated request.
1.0.2
- Security hardening: tightened a REST permission check, added nonce + capability verification to an admin GET action, unslashed/sanitised all request inputs, and converted database queries to fully prepared statements with
%itable identifiers.
1.0.1
- Code Snippets module removed — superseded by WPCode / Code Snippets (both free on WordPress.org) which serve this category competently. Asteris focuses on modules where it adds genuine differentiation (analytics pipeline, SEO+AI suite in paid, accessibility automation). Existing snippets in the
wp_asteris_snippetstable are preserved on upgrade — install a dedicated snippets plugin to continue using them. Module count is now 5.
1.0.0
- Initial release. Six modules: Code Snippets (full), SMTP, Image Optimisation, Activity Log, Accessibility Scanner, Analytics + Pixels.
