The Chrome Web Store has 180,000+ extensions. Roughly 87% of them have fewer than 1,000 users. The ones that break through — Grammarly (30M+ users), Momentum (3M+), Wappalyzer (2M+) — didn't compete on features. They found a specific gap that existing extensions missed. SCAMPER gives you seven systematic ways to find those gaps.

The Chrome extension gold rush

Chrome extensions are the fastest category to ship with AI coding tools. Cursor can generate a working extension from a single prompt. But speed-to-ship means the market floods quickly. There are 200+ tab managers, 150+ screenshot tools, and 300+ AI writing assistants. Competing on features in a saturated category is a losing bet. Competing on angle — a specific user, a specific workflow, a specific twist — is how solo developers earn $10K-50K/month from extensions.

Substitute the trigger

Most extensions activate when the user clicks the icon. What if yours activated automatically based on context? Grammarly succeeded partly because it appears when you start typing — no click required. What if your extension triggered when a user lands on a specific type of page, pastes a specific format, or opens a specific web app? The trigger substitution changes the entire user experience. Use SCAMPER for chrome extension ideas by starting with the activation model.

Combine two single-purpose extensions

Users install 5-10 extensions that each do one thing. What if you combined two of them? An extension that captures screenshots AND automatically uploads them to a project board. An extension that blocks distracting sites AND tracks how much time you saved. Mergestat combined Git data with SQL querying — same principle applied at a larger scale. Combination extensions reduce install count for users and capture two markets at once.

Adapt from mobile apps

Mobile-first features that haven't reached Chrome: swipe gestures for tab management, focus modes that hide parts of a webpage (like iPhone's Focus filters), streak tracking for productivity habits. Momentum adapted the phone homescreen concept (weather, greeting, task list) to the new-tab page and reached millions of users. What mobile interaction pattern can you bring to the browser?

Eliminate the UI

Most extensions open a popup with buttons and settings. What if yours had zero UI — it just worked? uBlock Origin's power-user appeal comes from its set-and-forget design. An extension that automatically reformats messy data tables on any webpage, with no settings, no popup, no configuration. Elimination reduces friction to zero, which increases adoption in crowded categories where users compare installation effort.

Reverse the workflow

Tab managers help you organize open tabs. What if an extension prevented tabs from piling up in the first place — auto-closing tabs older than 30 minutes? Bookmark managers help you find saved links. What if an extension surfaced forgotten bookmarks randomly, like a discovery feed for your own saved content? Reversals produce SCAMPER chrome extension ideas that feel counterintuitive and attract attention because they do the opposite of what the category expects.

Running your SCAMPER chrome extension ideas session

Pick a Chrome extension category you find overcrowded. Run Substitute, Combine, Adapt, Eliminate, and Reverse against it. Three minutes per prompt. Fifteen minutes total. You'll have at least three angles that don't exist in the current market — and each one is specific enough to prompt Cursor with.

Sparks trains SCAMPER across its entire first chapter — five difficulty levels, from guided to timed speed rounds. The same technique that generates chrome extension angles also produces SaaS concepts, feature ideas, and product pivots. AI scores every response for originality.
