alt Hacker NewsThe OSS point doesn't apply to every vertical. Open source applications come about when developers scratch their own itch. Developer tools, infrastructure, general purpose CRMs, project management get OSS alternatives because developers use them and want to build them.
Nobody is building open source software for [niche professional vertical] in their spare time. It's not mass market. It's not something a developer encounters in their daily work and thinks "I could do this better." The domain knowledge required to even understand the problem space takes months to acquire, and there's no personal payoff for doing so.
The "OSS will appear" prediction works for horizontal tools. For deep vertical SaaS, the threat model is different: it's other funded startups or internal enterprise clones (both of which we've already faced and won against).

As a matter of fact, I am (in the computer security vertical) - look for an announcement on Hacker News at the beginning of the year. I suspect that others are too, but there's always a discoverability problem for niche tools in verticals that one doesn't participate in, e.g. I know nothing about software for dentists but I know that at least one exists, and that there are probably a lot of dentists who use it but resent the fees, features or support, and there are probably some dentists who could manage an agentic coding project.
There have ALWAYS been niche OSS projects, and agentic coding will make them better and more prolific.
There are people like me who are passionate about a space and have the skills to manage an agentic coding project and the domain knowledge to design the software that they want, but not the skills and time necessary to have built the software in the absence of agentic AI. Last year I would never have started my 100k+ LoC project. This year I am proposing colleagues at two Fortune 50 companies to adopt it (at zero financial benefit to me). I am doing this from love of the problem space and desire to improve software security across the industry.
Most OSS is build by companies to commoditize their complement, not by some random devs building random stuff in free time.
