Is it still worth building a SaaS in 2026… or is AI going to eat everything?

Feels like every week there’s a new AI tool doing in minutes what used to take days. So where does that leave us? Are we still building real products… or just wrapping APIs and calling it a SaaS? I’m working on a small tool around debugging HTTP requests, and honestly I’m questioning this a bit. Curious how others see it: Are you still building SaaS products right now? Or shifting more into AI-first tools?
