Software is not a moat.
If you’ve ever tried any of the agentic AI tools out there, you know how trivial it is to give Claude Code a prompt like “Make me a better version of XYZ app/SaaS service/whatever that also does {ABC}”, and the tools will do it. This is especially true of systems like Cowork, OpenWork, OpenClaw, etc. – give them a great project plan and come back to working software in a few hours (assuming you don’t hit usage limits, of course).
Why is software not a moat? Because software is fundamentally the expression of ideas, and ideas are not protected under any law. Implementations are, with things like patents. Expressions are, with things like trademarks, service marks, and copyrights. And even those have nuances; courts ruled decades ago that musicians cannot copyright chord progressions as they are insufficiently unique.
When Claude Code’s source code leaked this week, what you saw were people taking the leaked codebase and passing it – ironically – through Claude Code to come up with better, cleaner implementations. Claude Code is written in Typescript/Bun, and more than a few folks immediately pivoted it to a pure Python app. From a copyright perspective, zero percent of a Python project will overlap a Typescript project. (I am not a lawyer, this is not legal advice. Consult a qualified attorney in your jurisdiction for legal advice specific to your situation)
If you’re building software in 2026 and expecting it to be a moat, you’re going to be very disappointed. A 1337coder can trivially replicate it in hours with an agentic tool. Your value proposition has to be levels up the value chain – what levels of service or experience come with the software that are difficult to scale and implement? What data does your software have access to that no one else has and can’t replicate easily?
Existing SaaS providers’ moats are the data and switching costs. It’s trivial to make a new CRM, for example. It’s exceedingly painful to get your vibe coded app to pass compliance checks and then migrate all your data and retrain your employees on the new system, no matter how good it is. That’s not to say big tech companies shouldn’t be worried; a company with no legacy data has no lock-in, and might find either vibe coding or forking an open source project faster and cheaper than a big tech provider.
The reality in 2026 is that code is a commodity, agentic AI can replicate your code-based idea in hours, and any defensible moat/business value must come from levels up the value chain past the code.
