Find Browser Extension Developers on GitHub

Browser extension developers are a fast-growing niche within the web development ecosystem. They build Chrome extensions, Firefox add-ons, and cross-browser tools that reach millions of users — and they have distinct tooling needs: Manifest V3 migration, storage APIs, content script bundling, cross-browser compatibility, and monetization. GitHub is where they discuss these challenges openly. GitLeads captures those conversations as lead signals.

Why Target Browser Extension Developers?

Extension developers are a concentrated audience with specific pain points. They are often indie developers or small teams with real budget for tools that solve their niche problems — testing frameworks, analytics, distribution platforms, and monetization tools. Finding them on GitHub before they discover your competitors gives you a significant first-mover advantage.

Enriched Lead Data for Extension Developers

For each signal, GitLeads returns: GitHub username, public email, name, bio, company, location, follower count, top programming languages, and the signal context (which repo was starred, which keyword triggered the alert, and where it appeared). Extension developers typically show JavaScript and TypeScript as top languages — use this to filter and personalize outreach.

Routing Extension Developer Leads

Push extension developer signals into Slack for real-time team alerts, HubSpot for CRM tracking, Smartlead for cold email sequences, or Clay for enrichment and persona building. GitLeads does not send emails — it finds the leads and routes them into your existing stack.
