Custom theme development
A theme built to your design, responsive and fast.
Agencies lose work because they can't ship it. The bottleneck isn't design. It's development.
Six months to onboard, no cover when they're ill. Then they hand in their notice.
Time zones on top. You carry the whole risk.
Bloated scope documents. And white-label? Forget it.
No meetings, no briefing marathon. You describe it, we build it.
Describe what you need, whether that's a bug, a plugin, a Figma build or a performance fix. Our AI reads the task before anyone picks it up.
Your dedicated dev team starts within 24 hours. Code review, QA and a staging test are part of it. You follow along live in the portal.
Review it on staging, give feedback, ask for a revision if you want one, then it ships. Under your brand, with no contact between us and your client.
Everything an agency needs to ship dev work fast, safely and under its own brand. WordPress, Shopify or custom code.
WordPress
WooCommerce
DevelopmentThe same people, project after project. They know your clients, your standards and your credentials. You never explain anything twice.
Upload the brief in the portal and your team starts. No quoting process, no waiting before the first commit.
Tasks, projects, credentials and messages in one place. One portal instead of five tools and an email thread.
Everything ships under your brand. No signature in the code, no mention in the legal notice, no contact with your client.
No email chaos. No WhatsApp groups. It all runs through your portal, from the task to the delivery.
We install a white-label plugin on every client site. You get full control, under your own brand.
Our connector generates magic links. Your team is inside wp-admin in a second, even with 2FA on.
Checks wp-config permissions, outdated plugins, default usernames and backdoor patterns. Recursive, every night.
Compares every installed file against the WordPress.org MD5 hashes. Modified or missing files show up immediately.
See at a glance which plugins need updating, which are inactive, and which are a security risk.
Performance, accessibility, best practices, SEO. Four scores plus Core Web Vitals per site, mobile and desktop.
The plugin is called whatever you want. 'Acme Site Manager'? Done. Your client never sees 'Webmaster Studios'.
Every task gets read straight away, every scope gets proposed, every status gets explained. Not as a gimmick, as a way to get more done.
