Hey fellow authors and WordPress developers 
Just wanted to share something we’ve built that might save you a TON of time if you’re creating and selling themes — especially here on ThemeForest.
Over the last few years, we at Keystone Themes have been developing commercial-grade WordPress themes for marketplaces like Envato and Creative Market. Along the way, we got tired of reinventing the wheel every time we launched a new product: writing update servers from scratch, building license validation systems, writing demo importers, etc.
So we packaged all of that into a reusable development toolkit.
What It Does:
- Base Theme framework (fast, modular, ThemeForest-ready)
- Theme Update System (API-based updates outside WP.org)
- License Verification (activation, domain binding, blocking unauthorized use)
- 1-Click Demo Importer (Elementor, Gutenberg, Classic Editor compatible)
- ThemeOps Dashboard (optional backend to track installs and licenses)
Why It Exists:
We’ve used this stack ourselves to power multiple approved and selling themes — so if you’re building commercial products and want to:
- Ship faster without backend overhead
- Own your licensing/update stack
- Ensure ThemeForest compliance
- Look professional from day one
This might be helpful.
We’re not linking directly here (to respect forum rules), but you can find more on our site — just search for Keystone Themes, then go to under “services” Keystone Toolkit, if you’re curious.
Would love to connect with others working on theme frameworks, toolkits, or similar systems. Let’s help each other raise the bar
