Frequently Asked Questions

Common operational and deployment compliance inquiries relative to extension assets.

What browsers do you develop extensions for?+

We primarily build for Chrome (Manifest V3), but also develop for Firefox, Edge, and Opera. Most extensions we build are cross-browser compatible from day one.

How long does a Chrome extension take to build?+

A simple productivity or utility extension typically takes 2–3 weeks. AI-powered extensions with backend integrations range from 4–8 weeks depending on complexity.

Can you integrate AI (ChatGPT, Claude, Gemini) into an extension?+

Yes — this is one of our core specialties. We can integrate any LLM API into your extension, including OpenAI, Anthropic, Google Gemini, and open-source models via Ollama.

Will the extension be approved on the Chrome Web Store?+

We follow Google's Manifest V3 policies strictly and handle the full submission process. We've successfully published extensions on the Chrome Web Store and work through any policy reviews alongside you.

Can you build a private, internal-only extension?+

Absolutely. Many clients want extensions distributed privately to their team via enterprise policy or unlisted Chrome Web Store links — we handle both distribution models.
