How to Use the Vendor Lock-in Severity Score
Find out how trapped you are on your current platform and what it would cost to leave. This tool analyzes API depth, export capabilities, fee structures, and audience portability to calculate a lock-in severity score from 0 to 100.
Step 1: Select the platform where you currently publish or sell (Substack, Patreon, YouTube, TikTok, Shopify, etc.).
Step 2: Enter your monthly revenue and email list size. The tool uses these to estimate the financial impact of migration.
Step 3: Click "Analyze Lock-in" to see your severity score, estimated revenue loss during migration, and a strategic recommendation for reducing your dependency.
You Are Renting Your Audience: The Vendor Lock-in Problem
Every creator, freelancer, and small business owner who builds on a third-party platform is renting their audience. Your 50,000 YouTube subscribers, your 12,000 Patreon supporters, your 8,000 newsletter readers on Substack: you do not own those relationships. The platform does. And when the platform changes its algorithm, raises its fees, or shuts down entirely, your audience evaporates overnight.
How Lock-in Happens
Vendor lock-in is not a single event. It accumulates over time through three mechanisms. First, content lock-in: your posts, videos, and products live on the platform's servers in their proprietary format. Second, audience lock-in: your followers are connected to you through the platform's notification system, not through a channel you control. Third, economic lock-in: the platform takes a percentage of your revenue, and switching means losing that income stream during the transition period.
The severity of each mechanism varies by platform. YouTube has deep audience lock-in (your subscribers are tied to the YouTube notification system) but moderate content lock-in (you can download your videos). Patreon has severe economic lock-in (supporters must manually re-subscribe on a new platform, and most will not). Ghost CMS has almost zero lock-in because you self-host everything and own your subscriber list directly.
The Migration Cost Formula
The tool calculates migration cost using a formula that accounts for four factors: the percentage of your audience you will lose during migration (typically 40 to 80% for platform-dependent audiences), the revenue gap during the transition period (usually 3 to 6 months), the technical cost of rebuilding your content on a new platform, and the opportunity cost of time spent migrating instead of creating. The result is a dollar figure that represents the true cost of leaving, which is often 2 to 4 times higher than creators expect.
The Email List Escape Hatch
There is one audience asset that is truly portable: your email list. Unlike social media followers, email subscribers are yours. You can export them, import them to any email service, and communicate with them directly without any platform in the middle. Every strategy recommendation in the tool includes "build your email list" because it is the single most effective hedge against vendor lock-in. If you have zero email subscribers today, that is your number one priority regardless of what platform you are on.
Frequently Asked Questions
Not necessarily. A high lock-in score does not mean you should leave immediately. It means you should start building escape routes: grow your email list, regularly export your data, establish a presence on a second platform, and consider self-hosting your core content. Migration should be strategic and planned, not reactive.
Self-hosted solutions like Ghost CMS, WordPress with WooCommerce, or custom-built sites have the lowest lock-in because you own everything. Among hosted platforms, Shopify and Gumroad offer good export capabilities. Social media platforms (YouTube, TikTok, Instagram) have the highest lock-in because your audience is entirely dependent on their algorithms.
Monthly at minimum. Set a calendar reminder. Export your subscriber lists, content archives, analytics data, and financial records. Store them in a location you control (your own cloud storage, not the platform's). If a platform changes its export policy or shuts down, your most recent backup is all you have.
