What we build
Browser Extensions & WordPress Plugins — the full scope.
Every item below is scoped, fixed-price and delivered by senior engineers, AI-assisted and human-verified.
Chrome & Firefox extensions
Productivity tools, scrapers, overlays and integrations on the current Manifest V3 standard.

Functionality the theme and existing plugins cannot give you, built the WordPress way.
WooCommerce extensions
Checkout tweaks, shipping logic, pricing rules, and payment or fulfilment integrations.
Internal / private add-ons
Tools distributed to your team or clients off-store, with a private update feed.
API & SaaS companions
An extension or plugin that connects an existing product to the browser or to WordPress.
Store submission & maintenance
Chrome Web Store, Firefox Add-ons and WordPress directory submission, plus updates.
How we work
Four steps from first message to live build.
- 01
Define the spec
We pin down exactly what the extension or plugin does, where it runs, and what it touches.
- 02
Scope & fixed quote
Numbered deliverables, the permissions involved, and a fixed price before work starts.
- 03
Build & test
We build it, test across the target browsers or WordPress versions, and review it with you.
- 04
Publish & maintain
We handle store or directory submission, and updates as browsers and WordPress evolve.

FAQ
Frequently asked questions.
- Can you publish to the Chrome Web Store and WordPress directory for us?
- Yes. We prepare the listing assets and handle submission to the Chrome Web Store, Firefox Add-ons and the WordPress plugin directory. Store review can take a few days, which we factor into the timeline.
- Will the extension work on more than one browser?
- Usually. Chrome, Edge and other Chromium browsers share the same build, and we can target Firefox from largely the same codebase. We confirm the exact browser list during scoping.
- Will a custom plugin break when WordPress updates?
- We build against the official WordPress and WooCommerce APIs and hooks — never by hacking core or theme files — so plugins survive core updates. We also test against new major versions and patch if anything shifts.
- Can the extension or plugin be private, not public?
- Yes. We can distribute privately to your team or clients with a self-hosted update feed, so you skip public store listings entirely while still getting automatic updates.
- Do you maintain it after launch?
- Two revision rounds are included in every quote. Browsers and WordPress change over time, so ongoing maintenance — compatibility updates and small improvements — is available as a separate plan.
