Can You Actually Make Money with Chrome Extensions? Yes. But the numbers are smaller than you think, and the strategy matters more than the code. I run 7 freemium Chrome extensions through ExtensionPay + Stripe. Here's the real data — no vanity metrics, no cherry-picking. Extension Category Free Tier Pro Price Procshot Productivity 5 captures/mo $9.99/mo DataPick Data tools 10-row preview $19/mo PromptStash AI tools 3 saved prompts $5/mo ReadMark Reading 5 bookmarks $4.99/mo InvoiceReader Business 10 checks/mo 980 JPY/mo CookieJar Dev tools Basic features $4.99/mo FocusGuard Productivity Basic blocking $5/mo Chrome Web Store doesn't have a built-in payment system. Users can't buy your extension before installing it. This means: User installs (free) User tries the extension User hits a limitation User decides to pay Freemium is the only model that works naturally with CWS's install flow. Instead of a traditional free trial, I use a reverse trial: users get Pro features for 7 days immediately after install, then drop to the free tier. Why this works: Users experience the full product before deciding No credit card required upfront The "loss" of features is more motivating than never having them Conversion happens when users feel the pain of downgrade The hardest part of freemium is setting the right limit. Too generous and nobody pays. Too restrictive and users uninstall. My framework: The free tier must be genuinely useful (not a crippled demo) The limit should be hit after the user has gotten value (not before) Pro features should be visible but locked (grey out, don't hide) Example — Procshot: Free: 5 procedure captures per month Pro: Unlimited captures + markdown/HTML/PDF export The limit hits after the user has already created valuable documentation Export formats are visible but locked with a Pro badge I use ExtensionPay which wraps Stripe for Chrome extension payments. The setup: Register extension on ExtensionPay Add ExtPay SDK to your extension ExtPay handles the payment page, Stripe processes payments Your extension checks payment status via ExtPay API Cost: ExtensionPay takes a flat fee per transaction on top of Stripe's standard 2.9% + 30 cents. The tricky part is checking subscription status in a Manifest V3 service worker that can be terminated at any time: Background service worker holds the ExtPay instance On payment/trial events, cache the subscription in chrome.storage.local Content scripts and popups query the background via chrome.runtime.sendMessage If background is sleeping, fall back to cached data (5-minute TTL) Periodic refresh via chrome.alarms (every 60 minutes) This ensures paid users never get locked out, even if the network or service worker is temporarily unavailable. $3-5/mo is the sweet spot for utility extensions. Higher prices work only for niche professional tools. Annual plans convert at 2x monthly when offered at a 40-50% discount JPY pricing for Japanese users increases conversion significantly (InvoiceReader: 980 JPY vs $9.99 equivalent) Average free-to-paid conversion: 2-4% across all extensions Reverse trial increases conversion by ~60% compared to no trial Users who hit the free limit within 7 days are 5x more likely to convert The paywall modal shown at the moment of limitation (not randomly) converts 3x better What Doesn't Work Aggressive upsell popups (users uninstall) Hiding features completely (users don't know what they're missing) Time-limited free trials without reverse trial (users forget to convert) Pricing above $10/mo for general-purpose tools My 90-day plan to reach $650/month: Month 1: Optimize free tier limits + implement reverse trial on all 7 extensions Month 2: Add annual pricing + improve paywall design + cross-promotion Month 3: Content marketing (Dev.to, Zenn) + Product Hunt launch for top extension The key insight: revenue growth comes from reducing friction in the conversion funnel, not from adding more features. Freemium is the only viable model for CWS Reverse trials outperform traditional trials Set free limits at the point of value, not before Cache subscription state aggressively for MV3 resilience Price at $3-5/mo for utility extensions Show Pro features locked, never hidden Built by S-Hub — 17 Chrome extensions, 7 with freemium monetization.
