Asteris Blocks

50 free Gutenberg blocks. Full-featured, and free forever.

Asteris Blocks gives you a polished, alphabetised block library covering everything you need to build landing pages, blog posts, and product pages. Every block is complete — nothing is locked behind a paywall, and the plugin never nags you to upgrade.

What you get

• 50 blocks — Hero, Pricing Table, FAQ Accordion (with schema), Recipe Card (with rich results), Comparison Table, Countdown, Cookie Notice, Code Block with syntax highlighter, Image Hotspots, Map (OpenStreetMap), QR Code, Before/After Slider, Table of Contents, and 37 more.
• 12 pre-built patterns — Hero + Stats, Pricing 3-tier, Full landing page, and more — one-click insert.
• 60 block style variations — Hero (minimal / split / gradient), Feature Grid (cards / icons-only / bordered / numbered), Pricing (classic / minimal / bordered / highlighted), and dozens more.
• Newsletter integrations — Mailchimp, MailerLite, ConvertKit, Brevo. API keys encrypted at rest (AES-256-CBC). See “External services” below.
• Schema.org markup — FAQ + Recipe + AggregateRating JSON-LD validates on Google Rich Results Test.
• HTML anchor IDs on every block — link anywhere, jump anywhere.
• Native typography + colour controls on every text-bearing block.
• 100/100 Lighthouse accessibility on Kadence, GeneratePress, Twenty Twenty-Five.

What you do NOT get

• No email-gated features — every one of the 50 blocks is fully functional, free.
• No nag screens, no pop-ups, no “your trial expires” timers in your editor.
• No tracking. No cookies. No analytics. The only outbound connections are the optional third-party services listed under “External services” below, and they run only when you add the relevant block to a page or configure a newsletter provider.

Asteris Blocks is full-featured and free forever — funded by our other products, not by upselling you. If you ever want premium section patterns and pro-level design controls, there’s an optional Asteris Blocks Pro — but the free plugin is complete on its own and never pushes you toward it.

Why Asteris Blocks?

Built lean on purpose. Here’s what you actually get:

1. Tiny footprint — about 215 KB zipped, and it loads zero front-end CSS or JavaScript on pages that don’t use an Asteris block.
2. Only loads where it’s used — the shared stylesheet and script enqueue only on pages where one of your Asteris blocks actually renders. No site-wide weight.
3. No JavaScript framework — blocks render in PHP with tiny vanilla-JS view scripts; no React or jQuery dependency dragged onto your front end.
4. 50 blocks, 12 patterns, 60 style variations — all free — nothing gated, no “premium” lock icons cluttering the inserter.
5. Schema built in — FAQ, Recipe and AggregateRating JSON-LD that validates on Google’s Rich Results Test, no separate SEO plugin required.
6. No phone-home — no tracking, no cookies, no analytics on you. The only outbound calls are blocks you choose to add (Map, Video, embeds) — each documented below.
7. Accessibility-minded — 100/100 Lighthouse accessibility on Kadence, GeneratePress and Twenty Twenty-Five.
8. GPL-2.0 — audit it, fork it, keep it forever.
9. No nag screens — Pro is mentioned once, never a pop-up or a disabled button.

Asteris Blocks Pro

Asteris Blocks is full-featured and free forever. If you want to go further, the optional Asteris Blocks Pro adds:

• 73 premium section patterns — niche page templates (photographer, music artist, conference, salon, fitness), video + audio sections, premium e-commerce layouts.
• The control layer — fine-tune any block’s spacing, responsive visibility, hover states, animations and custom CSS, no code required.
• AI Section Generator — describe a section and get a ready-to-edit block layout.
• Cloud pattern library — one-click insert from a growing hosted collection.

Same lightweight, no-bloat build. See everything included at asterisblocks.com/blocks-pro.

External services

This plugin can connect to the following third-party services. None of them are contacted unless you add the block that uses them to a page, or configure a newsletter provider. No data is sent to us.

Newsletter providers (optional). When you configure a provider and a visitor submits the Newsletter block, the visitor’s email address (and name, if entered) is sent from your server to that provider’s API to create or subscribe the contact. You choose the provider and supply the API key.

Spotify / SoundCloud (Embed block). Adding the Embed block with a Spotify or SoundCloud URL embeds that provider’s player. When a visitor loads the page, their browser requests the player and the track/episode you embedded from open.spotify.com or w.soundcloud.com. Only the public URL you paste into the block is sent.
