JnK Plugins
Welcome to the JnK Plugins documentation. These guides cover how each of our WordPress plugins works under the hood and how to extend it — the hooks, filters, and integration points a developer needs. They complement (rather than replace) each plugin’s in-dashboard help and its readme.txt.
Everything here applies to the free editions, which are open-source (GPL) and currently direct downloads from this site while our WordPress.org listings are under review. Where a capability is Pro-only, we say so and describe the behaviour — but the extension points documented here are all available in the free build.
The plugins
- EntryVault — turns form submissions from 11 builders into one unified Kanban CRM. Also see Writing an EntryVault adapter.
- Automatic Linker — server-side internal-link suggestions, auto-linking rules, and broken-link scans.
- Trinity Forms — a block-native form builder with native entry storage and CSV export.
Principles the plugins share
- Self-hosted, no SaaS. All processing and data stay inside your WordPress install. There are no per-request fees and no third-party service is required to run the core features.
- Free core, honest upgrade. Each plugin has a genuinely useful free tier. Pro adds a distinct layer (workflow, automation, scale) rather than unlocking basic functionality you’d expect for free.
- Extensible by design. Public WordPress hooks and filters let you adjust behaviour in code without touching the plugin — the same pattern you already use across the WordPress ecosystem.
