Open source

Free software, released in the open.

Tools we built for our own work and gave away. Free to download, free to run, free to fork — no licence fee, no account, no catch. The same engineering we bill for, in public where you can read every line.

The Hugging Face Space node in an n8n workflow canvas
n8n-nodes-huggingface-space

Run inference on any Hugging Face Gradio Space from n8n — images, video, music, speech, text, and moderation — with a curated model catalog and automatic fallbacks when a Space is cold or busy.

The Remote Exec node in an n8n workflow canvas
n8n-nodes-custom-exec

Run a command on a remote execution service — ffmpeg, ImageMagick, pandoc, anything you can invoke over HTTP — straight from an n8n workflow. Built so a media pipeline does not need a self-hosted worker just to transcode a file.

WordPress themes

Block themes
The Broadside WordPress theme rendering a broadsheet-style article layout
Broadside

A block theme that dresses a modern WordPress site as a broadsheet newspaper: a blackletter masthead, a folio rule, a three-column lead grid, and a long-read article layout. Ships with Broadside Blocks and requires it to be active.

WordPress plugins

For WooCommerce
Crypto for WooCommerce

A self-custodial payments gateway for WooCommerce. Customers pay the store's own wallet directly, and the plugin confirms the payment on-chain — ETH, USDC, USDT, and Bitcoin — before the order is marked paid. No custodian, no processor, no fees, and no keys on the server. Published to the official WordPress.org plugin directory and developed in the open.

American Gun Trader for WooCommerce

Keeps a licensed dealer's WooCommerce store in step with their American Gun Trader listings — inventory, pricing, and availability, synced automatically instead of maintained twice by hand. Built for our own marketplace and released for any dealer to run.

Broadside Blocks

Editorial blocks for WordPress built for long-form reading: a short-answer box, key takeaways, a self-building table of contents, an FAQ block that emits FAQPage schema, a sources list, and the masthead furniture a broadsheet layout needs.
