Yes, you can sell your Chrome extension — and depending on your user count and revenue, the payout can range from a few hundred dollars for a side project to five or six figures for a monetised, growing product. You don't need a legal team, a broker, or a million users. You need to know how buyers value extensions, where to list, and what paperwork protects you both. This guide covers all of it.
The Chrome extension market is valued at $2.5 billion and growing at 14% annually, projected to reach $5 billion by 2033 (HTF Market Insights, 2025). There are over 111,000 extensions in the Chrome Web Store right now (DebugBear, 2024). That supply creates a steady stream of buyers — operators, acquirers, and indie makers looking for shortcuts. Your extension might be one of them.
By the end of this guide, you'll know how to accurately value what you've built, which marketplace fits your extension's size and type, how to transfer ownership without exposing your source code, and the mistakes that leave money on the table or kill deals entirely.
Why Indie Makers Are Selling Chrome Extensions Right Now
The market for buying and selling small software products has matured significantly. Tools like Acquire.com and Flippa have normalised micro-SaaS exits at price points that indie makers actually care about — $1,000 to $50,000 — and Chrome extensions fit this bracket well.
The AI Chrome extension segment is particularly active. It's growing from $1.5 billion in 2023 to a projected $8.2 billion by 2032 at a 20.5% CAGR (Data Intelo, 2025). Buyers want AI-adjacent extensions with established user bases because the hard part — distribution and user trust — is already done. They want to buy what you spent months building and acquiring. If you're looking for extensions to acquire and rebuild, our guide on which expired extensions to rebuild maps the highest-potential opportunities.
Ihor Stefurak built Type Slash AI in 10 hours using ChatGPT, generated $1,000 in pre-orders within 24 hours of launch, listed it on Acquire, and sold it for thousands — all within a week (Business Insider, 2023). That timeline is exceptional, but it illustrates a real dynamic: buyers respond to momentum and traction signals, not just revenue history.
Even smaller extensions move. Zubair Ahmed sold Browser Stories for $1,000 on Side Projectors after six months and 100+ users (Indie Hackers). Prince sold Helper-AI for $3,500+ including the source code after just two months (Indie Hustle). The common thread: both sellers prepared their listing clearly, documented what they had, and found the right buyer for that tier.
How Do You Value a Chrome Extension Before You Sell It?
Valuation is where most indie makers undercharge. They look at their MRR and apply a rough multiple, but buyers look at far more than monthly revenue. Understanding the inputs gives you leverage in negotiation. If your extension isn't monetised yet, use our Chrome extension revenue calculator to estimate the MRR your user base could realistically generate — a defensible number that anchors your asking price.
The Standard Multiples Framework
Chrome extensions without revenue typically sell on a user-count and growth trajectory basis. Extensions with recurring revenue sell on a revenue multiple — typically 2x to 4x annual revenue (ARR) for small extensions, occasionally higher for AI-adjacent or sticky-use tools with low churn.
Here's how buyers break it down:
- Free extension, 1,000–10,000 users: $500–$5,000 range. Buyers pay for the audience and domain relevance, not earnings.
- Free extension, 10,000–100,000 users: $5,000–$30,000. Distribution is the asset — buyers will monetise it themselves.
- Monetised extension, $500–$2,000 MRR: $15,000–$60,000 at 2.5–3x ARR multiple. Revenue de-risks the acquisition.
- Monetised extension, $2,000+ MRR: $50,000+ depending on churn, growth rate, and niche. Institutional buyers enter at this level.
What Raises Your Multiple
Buyers pay more when they have confidence in what they're getting. Signals that raise your valuation include: a growing user count month-over-month, low uninstall rates, active reviews in the Chrome Web Store, documented monetisation (even early-stage), clean code with a README, and a niche with obvious upsell potential. Reading the buyer perspective in Secure Annex's breakdown of extension acquisitions gives you a clear map of what acquirers are actually checking.
What Lowers Your Multiple
Buyer concerns that compress price: extensions dependent on a single API that could break (especially unofficial third-party APIs), high-permission manifests (`
Where to Sell Your Chrome Extension: Marketplace Comparison
You have four main routes, and each suits a different extension profile. Picking the wrong channel wastes months.
Acquire.com (Formerly MicroAcquire)
Acquire is the highest-intent marketplace for micro-SaaS and extension sales. Buyers come pre-qualified; many are operators looking to add products to existing portfolios. The listing process requires revenue documentation and a data room. If your extension earns any MRR, start here.
Best for: Monetised extensions with $500+ MRR, or AI/productivity extensions with strong growth signals.
Watch out for: Acquire's buyer base expects financials. If you have no revenue and no detailed metrics, you'll struggle to get traction.
Side Projectors
Side Projectors operates at a lower price point and is more community-oriented. It's where Zubair Ahmed sold Browser Stories for $1,000. The process is lighter — you post a listing, set a price, and negotiate directly. Deals close faster and with less formality.
Best for: Early-stage extensions, free tools with small-to-medium user bases, or quick exits where speed matters more than maximum price.
Flippa
Flippa covers a broader range of digital assets — websites, apps, SaaS, and extensions. The fee structure is more complex and the buyer pool more varied. Extensions can perform well here if you write a strong listing with clear metrics, but the noise-to-signal ratio for extension-specific buyers is lower than Acquire.
Best for: Extensions with web traffic components, monetised through ads or affiliate links as well as direct subscriptions.
Direct Outreach
Some of the best extension acquisitions never touch a marketplace. If your extension operates in a niche dominated by a few SaaS companies, email their business development team directly. Describe your user count, growth rate, and use case. A competitor or complementary tool may pay a premium to acquire your audience or eliminate a feature overlap.
Best for: Extensions already embedded in a specific vendor's workflow (e.g., an extension that enhances a specific CRM, email client, or developer tool).
How to Prepare Your Chrome Extension for Sale
Preparation is the highest-leverage step in the selling process. Extensions that sell quickly and above asking price are the ones where buyers can verify everything they're told without needing to chase the seller.
Step 1 — Document Your Metrics
Pull together a clean one-pager covering: total installs, monthly active users, uninstall rate, review count and average rating, MRR (if applicable), month-over-month growth for the last 6–12 months, and traffic sources (organic search, Product Hunt, Chrome Web Store suggestion). Screenshots from the Chrome Web Store Developer Dashboard are your primary evidence. Google Analytics or PostHog data from any companion web properties adds credibility. Use Mangools to pull search volume data for your extension's niche keywords — showing buyers that organic demand exists for your category strengthens your listing and justifies a higher asking price.
Step 2 — Clean Up Your Code and Write a README
Buyers need to be able to maintain what they're buying. This means your repository should have a working README that explains the architecture, the dependencies, the build process, and any external API integrations. Comment your code where logic is non-obvious. If you're embarrassed to show a buyer your codebase, that's a signal to spend a weekend cleaning it — it directly affects your sale price. Create professional listing visuals and documentation assets with Canva — a polished sale package with clear diagrams and branded screenshots signals professionalism and justifies a premium.
The Chrome Web Store Best Practices documentation is also worth reading before a sale — buyers will check your listing against these guidelines to assess risk.
Step 3 — Resolve Any Policy Issues
Check your extension against current Google Chrome Policies and Guidelines and clear any active warnings in the Developer Dashboard. A buyer inherits your extension's compliance history. Active policy flags significantly reduce what buyers will pay, because the first thing they'll do is check your review status.
Step 4 — Prepare the Handover Package
A clean sale includes: the source code repository, the Chrome Web Store developer account access (or a documented process for transferring the listing), all API keys and third-party service accounts, your user database or relevant analytics exports, and documentation of any ongoing costs (hosting, API subscriptions, etc.).
Source code transfer is where many first-time sellers get nervous. The Stack Overflow thread on selling a Chrome extension without leaking source code covers the mechanics well: use an escrow arrangement (standard on Acquire) where code access is granted only after payment clears, not before. Never send your source code in exchange for a promise.
What Do Buyers Actually Look for in a Chrome Extension Acquisition?
Flipping the perspective to the buyer's side makes your listing dramatically more compelling. Buyers are not just buying a product — they're buying a distribution channel and a bet on future revenue.
Defensible User Behaviour
Buyers want extensions that users rely on daily, not occasionally. A to-do list extension used twice a week is less valuable than a form-filling extension used five times a day. Your uninstall rate and monthly active user percentage are the metrics that show this. If you don't track these, start now — even 60 days of data before listing improves your position.
Low Technical Risk
Buyers fear the extension breaking post-acquisition. Extensions that depend on unofficial scraping of third-party sites, undocumented APIs, or deprecated Chrome extension APIs represent technical risk. The closer your extension aligns with stable, documented Chrome APIs (see Chrome Extensions Get Started for the current API surface), the more confident a buyer feels.
A Clear Path to Monetisation
Even if your extension is free today, buyers want to see an obvious way to add revenue. A free productivity extension with 20,000 users and no paywall is an opportunity to a buyer, not a failure. But you should be able to describe the monetisation path yourself — a freemium model, affiliate links, or a subscription tier — because buyers will ask and a clear answer increases their willingness to pay. For more on monetisation models, see our Chrome extension monetization guide. For a complete development blueprint, our how to build Chrome extensions pillar covers the full journey from idea to published product.
Common Mistakes Indie Makers Make When Trying to Sell a Browser Extension
The difference between a smooth sale and a stalled listing usually comes down to a small set of avoidable errors.
Mistake 1: Pricing Based on Time Invested, Not Market Value
"I spent six months building this, so it's worth $10,000" is not a valuation methodology. Buyers don't care how long it took — they care about what they're acquiring and what it can generate. An extension built in 10 hours with 1,000 engaged users is worth more than an extension built in six months with 50 inactive ones. Price based on the multiples framework above, not on your effort. The Reddit community discussion in r/SaaS repeatedly surfaces this mistake from first-time sellers.
Mistake 2: Sharing Source Code Before Payment Clears
Several developers have reported being approached by "buyers" who request a code review as due diligence, receive the source, and disappear. This is a known pattern in micro-SaaS acquisition communities. Never provide full repository access before payment is confirmed. Use an escrow service — Acquire has this built in, and Escrow.com works for direct sales. A legitimate buyer will not object to this arrangement.
Mistake 3: Listing Without Metrics Documentation
A listing that says "great extension, 1,000 users, priced at $5,000" with no screenshots, no growth chart, and no revenue data will sit unsold for months. Buyers need to verify your claims. The more documentation you provide upfront — developer dashboard screenshots, install trend charts, review history — the faster offers arrive and the stronger your negotiating position. Preparing this takes three to four hours and directly affects your final price.
Mistake 4: Ignoring the Google Account Transfer Complexity
Chrome Web Store publisher accounts are tied to a Google account. Transferring the extension means either transferring the entire publisher account (which includes all extensions on that account) or using Google's group publisher feature to add the buyer as a manager. Many sellers don't know this until mid-negotiation, which stalls or kills deals. Understand the Chrome Web Store transfer process before you start conversations with buyers — it removes a common last-minute obstacle.
Is Selling Your Chrome Extension Worth Your Time as an Indie Maker?
Here's the honest ROI picture across different extension profiles.
| Extension Type | Time to Prepare (hrs) | Investment ($) | Expected Sale Range | Assumptions |
|---|---|---|---|---|
| Free extension, 500–2,000 users | 5–10 | $0–$50 | $300–$2,000 | No revenue; audience and niche fit |
| Free extension, 5,000–20,000 users | 10–20 | $0–$100 | $2,000–$15,000 | Growth trend visible; clear monetisation path |
| Monetised, $200–$500 MRR | 15–25 | $0–$100 | $8,000–$25,000 | 2.5–3x ARR multiple; low churn |
| Monetised, $1,000+ MRR | 20–40 | $100–$500 | $30,000–$80,000+ | 2.5–4x ARR; AI niche or strong retention |
Assumptions: Sale price ranges derived from published case studies (Indie Hackers, Indie Hustle, Business Insider, 2023–2025) and standard micro-SaaS acquisition multiples. ARR multiples (2–4x) are consistent with Acquire.com's published benchmarks for small digital assets. Preparation time assumes clean code and available analytics; messy codebases or undocumented metrics add 10–20 hours.
The key insight here is that preparation time has the best ROI of any step in this process. Spending 10 extra hours documenting your metrics and cleaning your code can shift your price from the bottom to the top of any given range. The actual sale negotiation is quick once the documentation is there.
Conclusion
Selling your Chrome extension is a legitimate exit strategy, not a last resort. The market is mature, buyers are active, and the transaction mechanics are well-established for deals at every price tier. Whether you're sitting on a free tool with 2,000 users or a monetised product with $800 MRR, there's a buyer category and a marketplace that fits.
The extensions that sell quickly and at their asking price have one thing in common: they're prepared. That means documented metrics, clean code, resolved policy issues, and a clear handover package. Most sellers who stall do so because they listed too early, priced based on effort rather than market value, or tried to skip the escrow step that protects both parties.
The Chrome extension market is heading toward $5 billion by 2033. AI extensions alone are on track for $8.2 billion by 2032. There are buyers in this market right now looking for exactly what you've built. The next step is knowing whether your niche and user profile match what they're actively seeking — and Chrome Goldmine gives you that category-level intelligence before you invest weeks preparing a sale package.
