Frequently asked questions
What types of extensions do you build?
Browser extensions for Chrome, Firefox, and Edge, plus platform add-ons and plugins, engineered for performance and store approval.
Can you publish the extension to the web stores?
Yes. We handle packaging, store listings, and the review requirements for the Chrome Web Store and other marketplaces.
How long does it take to build a browser extension?
Most extensions ship in 3 to 8 weeks depending on scope and integrations. We quote a fixed scope and price within one business day.
Can extensions integrate with our existing app or API?
Yes. We build extensions that securely connect to your APIs and existing product to extend its functionality.
Do you maintain extensions after launch?
Yes. Browsers and store policies change, so we offer ongoing updates, compatibility fixes, and support.
Take your business to the next level.
Tell us what you're building. We'll come back inside one business day with a fixed scope, timeline, and team — or an honest “this isn't a fit”.
Code is useless if it's not comprehensible to those who maintain it. We write code the next person can actually understand.
